How to Sit Properly at a Desk
It’s not just about finding a chair you like. We’ve rounded up several tips on how to set up your desk properly here, but here are a few highlights.
Sitting for too long in a day is not good for your health, no matter what chair you use. It increases the risk of type 2 diabetes, stroke, and heart disease. The best thing you can do is get up and move every half hour. If you can, a 40-minute walk per day can, according to a recent study, make a big difference in countering some effects of a sedentary lifestyle. You probably don’t need to bother with an active chair. Our recommendation? Try a smartwatch. Most have movement reminders that encourage you to stretch your legs. If you’re dealing with back pain, your first step is to consult your physician.
Make sure your chair’s armrests are adjustable. Your palms should be elevated over your desk, which should be elbow-level, and your wrists should be straight. If the bottom of your palm is resting on the desk or wrist rest, there’s a chance you’re putting too much pressure on your nerves, which could lead to issues like carpal tunnel syndrome. Talk to your physician if you’re feeling any kind of pain. A gaming mouse, often more ergonomic than a standard mouse, might be helpful; just make sure to find one that fits your palm size.
When you look forward, your eyes should align with the top of your monitor or laptop. That might mean finding a chair that can adjust up and down, elevating your laptop with a stand, or raising the height of your monitor. This puts less pressure on your neck and spine—you shouldn’t be craning your neck up or down.
What Should I Look for in an Office Chair?
A good rule of thumb is that the more adjustable a chair is, the better. Now, that doesn’t mean this chair is the absolute best, but it gives you the possibility to mold it to your body shape, which hopefully makes it a comfier and more supportive seat. Here’s what you can expect to adjust on a chair.
Armrests: Most chairs let you move the armrests side to side, up and down, forward and back. It’s even nicer when you’re able to lock the armrest into place so that they don’t slide around as your elbows rest on them. The armrest should naturally allow your palms to slightly hover over the desk. You’ll often see descriptors like “4D” and “5D adjustable armrests,” which denotes how many directions you can adjust the armrest.
Seat height: It’s worth checking a chair’s maximum and minimum height before you buy because they might not work for your current desk (unless you have a standing desk where you can adjust the height). This is usually a pneumatic lift lever under the chair—pull the lever and get off the seat to let the chair go up, then sit on it and pull the lever to bring it down to your preference. Your feet should be planted on the floor at a 90- or 100-degree angle. If your chair arrives and it doesn’t get as high as you’d like, don’t worry, there’s a very simple fix. Some office chair brands offer “tall cylinders” for not a lot of money, and if not, you can usually find third-party options on retailers like Amazon (make sure you buy for your specific chair!). Simply swap your existing cylinder with the tall version, and you’ll have a greater height range to work with. You may be able to choose this option before checking out, or reach out to the company to see if they can swap it for you.
Seat depth: Seat depth is important for taller folks. This is usually a mechanism that lets you pull the seat out so that your thighs get the proper support. There should be 1 to 2 inches between the front of the seat and the back of your knees. Taller people with longer legs may not get the best support if you can’t adjust the seat depth.
Seat tilt: This isn’t as common as the above adjustments but it’s designed to tilt the seat up or down. This can help posture and prevent back pain, though it can take some getting used to.
Lumbar support: Most office chairs offer lumbar support, which can look like a separate piece attached to the backrest that can slide up and down. This piece supports your lower back (the lumbar region!), specifically maintaining the curve of the spine to maintain good posture as you sit and, ideally, warding off back pain. Check your chair manufacturer’s assembly instructions to learn how to adjust the lumbar support, and place the support on the curve of your lower back. What I like to do is run my hand along my spine until I reach the natural dip, then I try to make sure the lumbar support sits at that exact location. Some chairs also let you adjust the depth of the lumbar support, pushing it further inward or outward. Make sure it feels natural and that it’s not digging in. Play around with this until it feels comfortable and natural. Your shoulders should align with your hips, and you shouldn’t feel like you’re leaning forward.
Recline: Almost every office chair lets you lock or unlock the recline, but some go a step further and let you tweak the tension of the recline. This allows you to use more or less force when you lean back, which comes down to how much resistance you want when you lean back.
How We Test Office Chairs
My home office is often filled with at least four or five chairs at any given time. It takes me a while to test them because I prefer to sit on these office chairs for more than two weeks at a bare minimum, though that often extends into a month. It’s hard to gauge the supportiveness of a chair by sitting on it for less than a week. I adjust it to my 6’4″ preferences, and sometimes have my 5’1″ wife sit on it for her two cents. I try out all the adjustments throughout the testing period, too. It’s not just about the chair; aesthetics are important, and I also research these companies, looking into their warranties, customer service, and overall reliability.
How Does WIRED Select Chairs to Be Reviewed?
I routinely look at the market to find new office chairs that have hit the scene, whether it’s from a newcomer or an established brand like Herman Miller. I typically reach out to these companies to ask for the product, but I do not promise any kind of editorial coverage—that goes against WIRED’s editorial polcies. Yes, WIRED earns affiliate revenue if you purchase an office chair using our link, but this is not factored into the decision process.
As much as I’d like to test and review every single chair, it’s just not feasible with our resources. You may find some notable missing options in this guide, like the Steelcase Leap. I’ll be testing it in the future, and will gradually try to evaluate all the top options in the market.
After I’ve finished testing a chair, I typically donate it to a local Goodwill. I keep a handful of top recommendations on hand so that I can reevaluate them or compare them to other newer options, like the Branch Ergonomic Chair Pro, Herman Miller Embody, and Anthros V2.
Accessories for Your Chair
Replace Your Casters
The wheels on the bottom of your chair are among the easiest parts to replace. If your current casters don’t roll smoothly or are too loud, it might be worth replacing them instead of buying a whole new chair. I like these from Stealtho, a Ukrainian company. They’ll work with nearly every office chair, though the company notes they don’t work with Ikea products. The soft polyurethane material means these won’t scratch or chip hardwood floors, as some plastic casters do, plus it’ll feel like you’re silently gliding as you roll from your desk to the fridge (don’t judge).
Fair warning: Since these are more frictionless than normal casters, they can cause your chair to roll around sometimes, like when you stand up and walk away. Stealtho has locking casters if you’re worried about your chair rolling, and they don’t cost much more.
An Office Chair for Your Pet
Does your pet longingly look at your fast-typing fingers and wish for scritches? Get SeatMate’s Pet Office Chair if you don’t want to feel like a cruel, cruel pet owner. This faux fur seat gets high enough that you won’t have to bend down to pet your dog or cat when they inevitably enter your home office to distract you. Instead, they’ll sit at a reasonable height that allows you to have one hand running through their fur, while the other tries very hard to work a keyboard and mouse simultaneously. There’s a pull-out ramp that lets them clamber up, and my dog instantly took to it, though now he’s so used to it he jumps straight onto the seat. The back legs of the seat are on wheels, making it easier to move around a room.
You can choose different fabric materials and colors, and it’s easy to clean with a brush or hand vacuum. Just keep sizing in mind. My dog is 19 pounds and a little long, and it just fits him when he sleeps.
A Glass Chair Mat
Do you need a mat for your chair? Most likely not. However, casters can scuff up hard floors, which is why we recommend upgrading them to rollerblade wheels (see above). If you’re on a carpet, it can also be hard to move around. A mat can help with both of these issues. I sat on top of this glass one from Vitrazza for two years and was pleasantly surprised. (You can go for much cheaper mats made from other materials, too.) The safety glass is thick, and I did not see any notable scratches even after that time. It holds 1,000 pounds and doesn’t touch my hardwood floor, as you need to affix rubber bumpers to keep them apart. You can choose from several sizes, and Vitrazza sells various shapes too. It’s just a bit difficult to clean since you have to lift it up to get to all the dirt underneath.
Seat Cushions, Backrests, and Footrests
If you can’t upgrade your seat just yet, a cushion or backrest might help. Here are a few we like:
CushionLab Seat Cushion for $75: This memory foam seat is comfortable, and I had no problems sitting on it for hours on end. It’s best paired with an adjustable chair, as it adds a decent amount of height to your seat, which might make typing on a keyboard awkward. It does a great job of keeping out bad odors, and you can also wash the cover. Just know that it’s rarely sold for its full price of $85, which means it isn’t really on “sale.”
LoveHome Memory Foam Lumbar Support for $22: If you slouch in your seat, this comfortable memory foam pillow can help. It keeps your back straight and supported, and as it’s affordable, it’s a great option to try before shelling out hundreds for a new chair. It’s good to use in a car or a wheelchair, too. The cover is washable, and it has two adjustable straps (plus an extension strap) that go around your seat to keep it in the position you need.
Secretlab Premium Footrest for $89: I have tried a handful of footrests, and Secretlab’s Premium Footrest is easily the best—I have been using mine for more than three years. Ideally, your feet are planted on the ground as you sit, but it’s nice to be able to prop them up on something soft every so often. Not only is the PlushCell memory foam material soft and cushy for my feet, but it also stays remarkably clean. I have a tiny dog, and his hair gets everywhere except the quilted fabric cover. (You can handwash this cover to get dirt out.) The patterned silicone base does a good job of keeping it in place, too.
Other Office Chairs to Consider
Not every pick is a winner. Here are a few others we like enough to recommend, but they’re not as good as our top picks above.
Photograph: Julian Chokkattu
Hon Altern Chair for $295: It’s hard to find a good office chair under $300. Most people will be better served with the Branch Ergonomic Chair pick above, which has dipped close to $300 during sale events, but the Hon Altern is a decent alternative. The best part about it is that the seat is wide and soft, so your butt will feel fairly comfortable, and the seat depth adjustment accommodates a larger group of people. However, the back support is lackluster. I want it to be more upright, but the chair forces me to lean backward. The armrests can only move up and down—I wish I could move them inward a bit more. Its design is also generic. Still, I sat on the Altern for a month, and it does the job. If your budget is tight, it’s far and away better than many of the options you’ll find at this price on Amazon. It includes a headrest, too, which is typically an extra add-on for many chairs.
Autonomous ErgoChair Ultra 2 for $399: I’ve now sat on Autonomous’s 3D-printed ErgoChair Ultra 2 for over a month, and I’m pleasantly surprised. It’s a big improvement over the original Chair Ultra, which had a flat and hard seat. The Ultra V2’s seat is still not as cushy as some chairs, but it doesn’t feel like I’m sitting on concrete. It has all of the adjustments you’d want, from seat depth to a recline lock, and I didn’t encounter any back pain. The all-mesh design offers good airflow, and the backrest is wide enough and doesn’t dig into my shoulders. The only flaw? Sometimes when I put too much pressure on the armrest (like when I’m getting up or shifting my weight), it goes down with a loud crack despite being locked in place. Also, Autonomous has a pretty lackluster two-year warranty despite the high price.
Haworth Fern for $1,242: I think the Haworth Fern is best for shorter people (aka anyone not above 6 feet, like me). It’s adjustable to the nth degree—you can even tilt the seat for a more upright sitting position!—but the seat itself was just wide enough for me, though it’s plenty soft and pillowy. When I pulled out the seat depth to the max, it created a gap between the seat and the backrest, and I didn’t love this feeling. The backrest is nice and soft, but I’d argue the lumbar support is quite aggressive. My back just felt like something was there all the time, and it felt distracting. I don’t think you’d have these issues if you are shorter and narrower, and it’s otherwise one of the softest office chairs I’ve sat on.
Autonomous ErgoChair Pro for $399: Our top pick, the Branch Ergonomic Chair Pro, is a better buy, but if you need a headrest and want a wide seat, consider the Autonomous ErgoChair Pro. I sat on it for a month with no major problems, except that the box it came in was massive and barely fit through my front door. The levers also aren’t super intuitive—I highly recommend checking out this video from the company when you first set it up to dial in your preferences. All the standard adjustments are present, from seat depth and lumbar support to fine-tuning the recline. What surprised me more was the ability to tilt the seat so it’s angled down—you don’t see that in many chairs. The overall build quality has been solid, and I even enjoyed the headrest when kicking back to watch House reruns during lunch. The only woes? I wish the arms stayed locked, as they can slide back and forth. While the foam seat is quite comfy, it can get warm in a toasty room (though the mesh back helps keep things cool). It’s a shame this company has an abysmal warranty period.
Staples Hyken for $145: The humble Hyken is frequently available for just $140 during big sale events, making it one of the most affordable good chairs out there. It reclines, has a breathable mesh fabric on the back and seat, and it’s sturdy. You even get a headrest and lumbar support. After five years of continuous sitting, WIRED reviewers say the Hyken’s mesh has compressed a bit, but it’s still comfy. The Staples Dexley is slightly wider, so get it if you need a wider seat.
Nouhaus Ergo3D for $350: This is another all-mesh chair. The ElastoMesh seat isn’t as comfy as the Steelcase Karman (it’ll feel worse on the skin if you, uh, tend to sit at your desk without pants), but it’s otherwise quite adjustable and roomy, plus it even comes with two sets of wheels (casters or rollerblades) so you can choose which works best for you and your flooring. If you’re in a particularly hot environment, it won’t trap heat and will keep your whole body cool for a fraction of the price.
Haworth Breck for $419: I like Haworth’s newest chair, the Breck. After sitting on it for a month, I didn’t have problems (no back pain!), though I can safely say it’s better suited for shorter people (roughly under 5’8″). That’s because the Breck’s seat is short, and the seat depth only extends an extra 2 inches. The weight-activated recline requires some push on your end, more than you might expect—it wasn’t too hard for me, but lighter-weight people may find it problematic. The seat padding is thin, but I didn’t see this as an issue even after hours of sitting. The best part is how amazingly simple it is to set up—no tools required! But my main gripe? Simply getting up from the seat causes the gas spring cylinder to loudly lift. This, and the fact that it tends to make some noises when I fidget around, makes it feel a little cheap.
Branch Verve for $599: The Verve used to be a top pick above, but I think the Ergonomic Chair Pro is a better value considering they’re similar in price. It is elegant (especially in the lovely Coral and Cobalt colors), it keeps my back straight, and it’s quite comfy. It can make nearly the same adjustments, but there’s no seat tilt, and the armrests are much more limited. I also wouldn’t have minded if the seat was a smidge wider—folks who need a wider seat may want to look elsewhere. I try to sit on these chairs for several weeks, if not months, but I rarely can sit on one for years, as I have so many to test. However, I have a colleague who owns the Verve who said that after more than two years, the seat started to sink whenever he sat on it. Thankfully, he says Branch’s customer service was very responsive and promptly sent him a new cylinder.
Eureka Ergonomic Royal Chair for $450: Some folks chase that executive aesthetic—you know, plush leather and a high back so you can swivel around and reveal a cat in your lap as you laugh maniacally. This chair from Eureka fits the bill without costing a fortune, and it’s been an OK chair for the month I’ve sat in it. The setup was quick, and the seat and back are soft and a little bouncy. I found my back sweaty after a few hours of sitting because there was just nowhere for body heat to go. The lumbar support isn’t great, as prolonged sitting has left me with some sensations in my lower back. Not pain, just my back telling me I ought to get up. There’s not much to adjust, but the recline and headrest. Also, if you need a wide seat, this is not the chair for you, as the armrests will feel like they’re boxing you in (it just fits me, and I’m 6’4″). I thought this chair would look pretty poor after a month, but it’s easy to clean with a damp cloth, and the fake leather has held up. Too bad about the two-year warranty.
Secretlab Titan Evo for $549: Our review of the Secretlab Titan Evo gaming chair says it’s classy enough for the home office. It sets itself apart from similarly priced competitors with its durability and flexibility. It’s comfortable for marathon gaming sessions, thanks to the adjustability it offers (particularly the lumbar support). The headrest pillow is magnetic and stays attached to the chair, which is a nice touch. But the firm, cold cure foam molds to your body and may not suit everyone. It will also make you feel sweaty.
Allsteel O6 for $1,279: While this chair is eye-searingly expensive, every part—from the casters and the adjustments to the design—is incredibly refined. The adjustable lumbar support provided shockingly good support even for hours of work. My only complaint is that the armrest adjustments are a bit stiff, but besides that, this is an exceptional chair that’s comfortable and intuitive enough for me to completely forget about once I sit down and start working. Fair warning: The 06 comes fully assembled, which is nice, but the box is massive. —Henri Robbins
Hinomi X1 for $649: Hinomi’s X1 mesh chair has a trick up its sleeve—a built-in footrest! Just extend and flip out the footrest; voilà, your feet are now propped up. This might not be very practical for fellow tall people, as my legs often hit the wall behind my desk, but it’s quite comfy. I also just didn’t end up using the footrest as much as I thought. The chair is otherwise well-built. I like the lumbar support here, and there’s a good amount of adjustments you can make. The seat itself is a bit firm, but I got used to it after some time. Hinomi offers a 12-year warranty.
Odinlake Ergo Max747 for $899: The Ergo Max747 is, all around, a great seat to sit in. The three-piece back provides great back support and comfort, and the easy-access paddles on either side of the seat make most adjustments quick and simple. Even sitting for hours, I never felt uncomfortable, whether I was sitting up or reclining (this chair reclines incredibly far, from 90 to 135 degrees). The bag holder in the back (which I typically used to hold a hat or small backpack) was a surprisingly nice touch, and the mesh backing and seat are breathable, preventing overheating during prolonged use. I still don’t know how I feel about the polished metal frame, and the inclusion of gloves for assembly makes me worry about how easily this seat will pick up smudges over the years, but the polished finish itself is spotless and well-executed. At 6’3″, I had to max out the back height to comfortably sit in the chair. The secondary adjustments (back height, lumbar support, and headrest height) were awkward to adjust due to complicated ratcheting mechanisms keeping them in place. However, the comfort and breathability of this chair make it a compelling choice. —Henri Robbins
Vari Task Chair for $399: Vari’s Task Chair is surprisingly comfy given its relatively simple construction. Former WIRED reviewer Medea Giordano tested it and asked her husband to use it during his long gaming sessions. They agreed that the angled back provides ample lumbar support to make those sessions comfortable. It also takes very little time to construct. You can recline a bit, but even at the lowest tension, it pushes you back up, and there’s no head support. It’s more for rocking than actually leaning. Her biggest gripe is that the armrests are quite hard. A little more padding would be a huge improvement.
Branch Softside for $299: I tested the high-back version of the Softside and like it a lot. It’s different from all the other chairs in this guide, but comfy and cushiony. If you need a wider seat, this might not be the option for you, as the armrests do box you in. There’s not much to adjust, but my back didn’t have any issues after weeks of sitting for full workdays. The build quality overall is OK. Considering it starts at $299, the overall seating experience, and the lovely design in fun colors, this is a pretty good value if you are after a soft and cushiony experience.
BodyBilt Midcelli for $949: BodyBilt’s chair looks quite average, but the seat pad is plushy and soft, and it’s contoured to your butt and legs, which I liked more than I expected. The mesh back has some give to it, so it doesn’t feel rigid, and there are all the usual points of adjustment, including moving the seat forward and back. I wish the arms could lock to a position. It has a lifetime warranty on select parts, while other chair areas are covered for 12, seven, five, or three years. There are more customization options on BodyBilt’s website—with the option to get a consultation—but I just think it’s overpriced.
Razer Fujin Pro for $1,050: Razer is asking Herman Miller and Steelcase prices despite offering a measly five-year warranty on this $1,000-plus chair. Still, my former colleague Eric Ravenscraft liked the Fujin Pro (8/10 WIRED Recommends). There are a good number of adjustments you can make; the armrests are useful, and the mesh is breathable. Oh, and it doesn’t have the overused gaming chair race-car seat aesthetic.
Tempur-Pedic Tempur-Lumbar Support Office Chair for $352: I think this is a nice alternative to the Branch Ergonomic Chair above. The Tempur seat cushion is, perhaps unsurprisingly, wonderfully comfy to sit on for hours at a time. And most chairs that have a thick lumbar cushion end up causing me back pain, but not here—I’ve had no issues sitting on it for a month. The mesh back is nice for airflow, too. The arms tend to move around a bit, though, and the mechanism to adjust them is not elegant. Installation wasn’t too hard, but the instructions weren’t as simple as Branch’s, and the overall build quality feels cheap.
Knoll Newson for $1,424: This minimalist chair looks best in the graphite and petal colors; it’s a bit drab in black and umber. It’s nice that I didn’t have to fuss with any levers or knobs much—it’s comfy out of the box and decently adjustable if you need to make some tweaks—and it feels especially nice when you recline. (The red knob adjusts the tension of the recline, but you need to twist it for five rotations, and I found it hard to turn sometimes.) The Newson didn’t give me trouble in the two months I sat in it. I’m just not a huge fan of how the elastomer mesh backrest distorts, depending on how you sit. It feels lumpy. This seat also doesn’t let me sit as upright as I’d like, but maybe you’re fine with a bit of give. Ultimately, it’s the price that pulls it out of our top recommendations, but you do get a 12-year warranty.
Kelly Clarkson Home Louise Velvet Task Chair for $165: There’s absolutely nothing you can adjust on this chair except its height, but it’s cute, and the seat is comfy. The velvet polyester was surprisingly durable and looked nice even after several weeks of sitting on this chair. The gold finish on the frame and legs chipped off in one area when I was unboxing it—it’s frequently under $200, OK? But my biggest issue is that it is not compatible with tall or larger people. My wide shoulders caused my arms to stick out of this chair, making it difficult to type. However, I asked my 5’1″ wife to try it, and it suited her narrower frame well. She didn’t find it hard to use her computer. With a 30-day warranty, you get what you pay for, but this chair is more about aesthetics than anything else. Oh, and Kelly Clarkson, because she hand-picked this product for Wayfair.
X-Chair X2 K-Sport Management Chair for $969: This used to be our top mesh chair pick, but it has been supplanted by the Steelcase Karman. Sitting in the X-Chair feels like lounging in a hammock. Every part of my body feels well supported, and you can adjust nearly everything on the chair. Pull the seat up and push the armrests up, down, and side to side, or angle them in or out. The lumbar support feels like a cushion, and it adjusts as you move in your seat. If you want to rest your head, you can pay extra for the headrest. It has held up extremely well after three years of near-continuous sitting, but I don’t like how bulky it is. X-Chair has several models to choose from. I tested the X-2 K-Sport with the wide seat, and it fits my 6’4″ frame well, but it was too wide for my partner, who is 5’1″. Most people should be fine with the standard X1.
Ikea Markus for $300: The Markus is a perfectly fine office chair. It’s not the most comfortable, but it’s far from the worst. The mesh design keeps you cool, and the tall back lets you fully lean into it. It’s rather thin and isn’t obtrusive in a small home office or bedroom. It was annoying to put together (lol, Ikea), and you might need someone to hold up the back of the chair while you properly attach the seat. Unfortunately, if you often sit with at least one leg up or with your legs crossed, the width between the arms will make you uncomfortable.
X-Chair X-Tech Executive Chair for $1,845: Functionally, the X-Tech is similar to the X-Chair above. In this version, the M-Foam cooling gel seat is indeed wonderful to sit on, though it’s not as heat-wicking as the all-mesh versions. It’s the Brisa Soft Touch material that impresses the most—it’s ridiculously soft. I recommend you stick with the standard armrests instead of the FS 360 armrests, which tend to move about too much. But my biggest gripe with this model is the price. Why on earth does it cost that much?
Mavix M7 for $777: If it looks strangely similar to the X-Chair (see above), that’s because both are owned by the same company. WIRED reviewer Louryn Strampe ran into some issues with assembly, but customer service was able to exchange the model without much effort. The M7 has similarly adjustable armrests and seat angles, but you get wheels that lock. The mesh back and wide seat construction keep you cool and comfortable during sweaty League of Legends sessions, and the lumbar support does the job. If you’re short, contact customer support while ordering—Mavix offers shorter cylinders so your feet touch the ground.
Hon Ignition 2.0 for $477: The Ignition 2.0 is easy to set up and looks great, but it gave me really bad back pain, which is why I originally placed it in our “Avoid” section. I thought it was perhaps the long hours I was working, so I switched back to the Knoll Newson Task chair, and my pain quickly began to ease. Sometime later, I gave it a shot again. After a few hours, the pain came back, and switching to another seat dissipated it. Color me confused, because this chair has positive reviews around the web. I then asked a friend who is around 5’4″ to try it for a few weeks, and she has had zero issues. This seems to be the answer. It’s possible the Ignition doesn’t work for my 6’4″ self and is better suited for smaller folks.
Pipersong Meditation Chair for $359: Have a problem sitting in a traditional chair? If your legs need to be bent and twisted for you to be comfortable, you’ll want to check this seat out. It has a 360-degree swiveling footstool that can accommodate pretty much any sitting position you want. I can go from kneeling to cross-legged to one leg up, one leg down. It’s possible to sit regularly too, with the footstool behind you and your feet flat on the floor. It’s the only chair I’ve found that’s designed for odd sitting habits. There are no armrests, which I didn’t mind because that’s what makes it possible to sit in many of these positions. The actual stool and chair back could stand to be bigger and taller, respectively. I had to use a pillow to keep my back comfy. —Medea Giordano
Avoid These Chairs
If you come across these models, I recommend you save your cash and go for one of the picks above.
TopJob Napa: The Napa should be $200 or $250 at best, nowhere near its $449 asking price (though it does seem to have a perpetual discount on TopJob’s website for $359). It looks attractive, especially in the amber vegan leather. My back surprisingly didn’t complain after more than a week of sitting in it for several hours a day. I wouldn’t say it’s comfy, there’s not much plush to the seat and backrest, but it’s not too uncomfortable. It doesn’t have many points of adjustments—you can adjust the armrest height, lock the recline at a few degrees, and adjust tilt tension. That’s it. Technically, you can adjust the headrest, but mine would not stay put at a specific height. You can pull out a footrest, but I found it more gimmicky than useful. The overall quality is a little cheap. You can do better at this price.
Humanscale World One: Despite hailing from the well-renowned Humanscale, this chair looks quite bland. The setup was fairly quick, and … interesting. You have to hammer two pegs to affix the backrest to the seat, which I’ve never before had to do, after testing dozens of office chairs. It just feels cheap and a little too plasticky. Like other Humanscale offerings, there are no adjustments to make as the chair will handle it all for you (you can adjust the seat and armrest height). I loved this on the pricier Humanscale Freedom, which felt like someone was cradling my body. But here, I find my body constantly shifting in the all-mesh World One, trying to find a comfy way to recline. The mesh material also feels like it digs in a bit. This could all be because I’m 6’4,” as the chair feels like it’s better suited for shorter people. However, I think you can do better at this price.
Herman Miller Vantum: Initially, I liked the Vantum. I liked how I could keep myself in a super upright position, which made me feel more engaged in what I was doing. The mesh backrest also disperses heat quite well. However, the overall build quality feels cheap and doesn’t scream Herman Miller (nor does the asking price, which has since dropped by $200). The headrest isn’t great either—I’ve nearly broken it trying to move it up and down. As I kept sitting, it was the back support that disappointed me the most. You can feel the lumbar support on your lower back, and not in a good way, almost like it’s digging in. At least it didn’t give me back pain.
Vilno Nobel Kneeling Chair: It’s a freakin’ kneeling chair! It was easy to put all the wood pieces together, and the seat cushion was surprisingly plump. This is what’s known as an active chair, meant to keep your body moving and keep your posture straight. It feels effective for the first few hours, but unfortunately, rocking in the seat tends to cause it to move around on the floor, so I frequently had to fix my position. Worse yet, my shins and knees grew fatigued, and I started feeling some pain after a few days. You can’t adjust its height, so it needs to be paired with a standing desk so that your palms don’t rest on your desk.
Flexispot C7: While this chair is simple to assemble and looks good, it feels flimsy. The entire back flexes and warps whenever you move, and the lumbar support is barely connected to the rest of the chair, meaning it audibly scratches against the main section of the back every time you adjust and hardly feels like it provides any actual support. The footrest bends whenever weight is put on it, and the foam seat cushion collects crazy amounts of pet hair. It feels like just a few extra screws and supports would have made this a good product, but in its current state, there isn’t enough material to make it feel sturdy. —Henri Robbins
Steelcase Series 1: WIRED reviewer Louryn Strampe says her biggest issue with the Series 1 is with the armrest—the tops slide back and forth and side to side, which could be a good thing, except she managed to pinch her arm every time she moved. There’s no way to lock them in place, so while she felt supported, her arms weren’t. The seat is also pretty curved, which can feel like you’re trapped in one position as you work throughout the day.
Sihoo Doro S300: Former WIRED reviewer Medea Giordano tested the Doro S300, which, in white, looks like it came straight out of the Space Force situation room. She found it comfortable. There are several adjustments you can personalize, like seat depth and recline angle. You can recline quite far, but she says she wishes there were a footrest to enjoy the lowest recline position. She typically prefers a cushy gaming chair, but she says she had no trouble sitting on this seat all day—the dual lumbar support helps too. However, the headrest is too low for her to lean against, even at its max height, and the arms move too easily. Simply placing her arms down pushes them out of position. It’s also squeaky and overpriced.

Robot regret: New research helps robots make safer decisions around humans

Imagine for a moment that you’re in an auto factory. A robot and a human are working next to each other on the production line. The robot is busy rapidly assembling car doors while the human runs quality control, inspecting the doors for damage and making sure they come together as they should.
Robots and humans can make formidable teams in manufacturing, health care and numerous other industries. While the robot might be quicker and more effective at monotonous, repetitive tasks like assembling large auto parts, the person can excel at certain tasks that are more complex or require more dexterity.
But there can be a dark side to these robot-human interactions. People are prone to making mistakes and acting unpredictably, which can create unexpected situations that robots aren’t prepared to handle. The results can be tragic.
New and emerging research could change the way robots handle the uncertainty that comes hand-in-hand with human interactions. Morteza Lahijanian, an associate professor in CU Boulder’s Ann and H.J. Smead Department of Aerospace Engineering Sciences, develops processes that let robots make safer decisions around humans while still trying to complete their tasks efficiently.
In a new study presented at the International Joint Conference on Artificial Intelligence in August 2025, Lahijanian and graduate students Karan Muvvala and Qi Heng Ho devised new algorithms that help robots create the best possible outcomes from their actions in situations that carry some uncertainty and risk.
“How do we go from very structured environments where there is no human, where the robots are doing everything by themselves, to unstructured environments where there are a lot of uncertainties and other agents?” Lahijanian asked.
“If you’re a robot, you have to be able to interact with others. You have to put yourself out there and take a risk and see what happens. But how do you make that decision, and how much risk do you want to tolerate?”
Similar to humans, robots have mental models that they use to make decisions. When working with a human, a robot will try to predict the person’s actions and respond accordingly. The robot is optimized for completing a task—assembling an auto part, for example—but ideally, it will also take other factors into consideration.
In the new study, the research team drew upon game theory, a mathematical concept that originated in economics, to develop the new algorithms for robots. Game theory analyzes how companies, governments and individuals make decisions in a system where other “players” are also making choices that affect the ultimate outcome.
In robotics, game theory conceptualizes a robot as being one of numerous players in a game that it’s trying to win. For a robot, “winning” is completing a task successfully—but winning is never guaranteed when there’s a human in the mix, and keeping the human safe is also a top priority.
So instead of trying to guarantee a robot will always win, the researchers proposed the concept of a robot finding an “admissible strategy.” Using such a strategy, a robot will accomplish as much of its task as possible while also minimizing any harm, including to a human.
“In choosing a strategy, you don’t want the robot to seem very adversarial,” said Lahijanian. “In order to give that softness to the robot, we look at the notion of regret. Is the robot going to regret its action in the future? And in optimizing for the best action at the moment, you try to take an action that you won’t regret.”
Let’s go back to the auto factory where the robot and human are working side-by-side. If the person makes mistakes or is not cooperative, using the researchers’ algorithms, a robot could take matters into its own hands. If the person is making mistakes, the robot will try to fix these without endangering the person. But if that doesn’t work, the robot could, for example, pick up what it’s working on and take it to a safer area to finish its task.
Much like a chess champion who thinks several turns ahead about an opponent’s possible moves, a robot will try to anticipate what a person will do and stay several steps ahead of them, Lahijanian said.
But the goal is not to attempt the impossible and perfectly predict a person’s actions. Instead, the goal is to create robots that put people’s safety first.
“If you want to have collaboration between a human and a robot, the robot has to adjust itself to the human. We don’t want humans to adjust themselves to the robot,” he said. “You can have a human who is a novice and doesn’t know what they’re doing, or you can have a human who is an expert. But as a robot, you don’t know which kind of human you’re going to get. So you need to have a strategy for all possible cases.”
And when robots can work safely alongside humans, they can enhance people’s lives and provide real and tangible benefits to society.
As more industries embrace robots and artificial intelligence, there are many lingering questions about what AI will ultimately be capable of doing, whether it will be able to take over the jobs that people have historically done, and what that could mean for humanity. But there are upsides to robots being able to take on certain types of jobs. They could work in fields with labor shortages, such as health care for older populations, and physically challenging jobs that may take a toll on workers’ health.
Lahijanian also believes that, when they’re used correctly, robots and AI can enhance human talents and expand what we’re capable of doing.
“Human-robot collaboration is about combining complementary strengths: humans contribute intelligence, judgment, and flexibility, while robots offer precision, strength, and reliability,” he said.
“Together, they can achieve more than either could alone, safely and efficiently.”

Warehouse automation hasn’t made workers safer—it’s just reshuffled the risk, say researchers

Rapid advancements in robotics are changing the face of the world’s warehouses, as dangerous and physically taxing tasks are being reassigned en masse from humans to machines. Automation and digitization are nothing new in the logistics sector, or any sector heavily reliant on manual labor. Bosses prize automation because it can bring up to two- to four-fold gains in productivity. But workers can also benefit from the putative improvements in safety that come from shifting dangerous tasks onto non-human shoulders.
At least, that’s the story employers such as Amazon have—largely successfully—promoted to the public.
In a recent study, Brad N. Greenwood, Dean’s Distinguished Professor at the Costello College of Business at George Mason University, investigated this question: Does automation make warehouse jobs safer? His co-authors include Gordon Burtch of Boston University and Kiron Ravindran of IE University. Their findings, which appear in ILR Review, reveal that the answer depends on how safety is defined.
The researchers distinguish between two types of injuries: severe and non-severe. Severe injuries include broken bones, traumatic falls, and other incidents that cause employees to miss work. Non-severe injuries include sprains, strains, and repetitive motion problems, often leading to reassignment or light-duty work, but not missing work.
The findings showed that robots do seem to reduce severe injuries. In robotic fulfillment centers (FC), tasks like heavy lifting and long walks are handled by machines, reducing workers’ exposure to physical hazards. The researchers found a meaningful drop in the number of severe injuries in these facilities.
However, the overall picture is not so clear. In the same robotic warehouses, the researchers observed a sharp increase in non-severe injuries, especially during high-demand periods such as Amazon Prime Day and the winter holidays. The robotic fulfillment centers experienced a 40% decrease in severe injuries but a 77% increase in non-severe injuries compared to traditional centers.
To better understand their results, the researchers also analyzed thousands of online posts from Amazon warehouse workers.
“There was an immediate and obvious discrepancy in worker opinion, based on whether their fulfillment center was roboticized or not,” says Greenwood.
Humans working alongside robots described their daily experience as “not physically exhausting” and “better than working at a legacy FC.” However, they also reported being expected to meet much higher performance metrics than their counterparts in non-automated FCs—amounting to a two-to-three-times higher “pick rate” in some cases. The faster pace of the human/robot dance was accompanied by a far more repetitive work routine that induced burnout in some workers, while causing others to “zone out.”
This dual reality—robots reducing some injuries while exacerbating others—has serious implications. For employers, simply introducing automation is not enough. Without careful job design, task rotation, and realistic performance goals, the shift to robotics can create new health and safety risks.
“Companies have bottom-line reasons to take this issue seriously. Beyond simple issues of liability, there is a cost to the firm of workers being unable to perform their duties,” says Greenwood.
Traditional safety metrics often focus on injuries that result in lost workdays. But as the nature of work changes, this approach may miss more subtle forms of harm. Chronic, repetitive injuries may not lead to time off, but they still decrease worker well-being and performance.
Looking ahead, Greenwood and his colleagues plan to explore how these trends play out over longer timeframes and in other industries. As robots become more common in fields like manufacturing, retail, and health care, similar patterns may emerge. The researchers hope their findings will help inform both corporate and public policy, ensuring that the future of work is not only more efficient but also humane.
“That isn’t to deny that warehouse robotics benefits workers,” Greenwood explains. “But we need to think more carefully about how to use them, and what that means for the humans they work with.”
