Night Sweats, Be Gone! Here Are the Best WIRED-Tested Cooling Mattresses
Honorable Mentions
There are a ton of mattresses and related items on the market that claim to have cooling benefits. Here are a few others we tested and liked, but not as much as the options above.
BedJet 3 for $427: WIRED reviewer Christopher Null liked this climate-control device a lot because it allowed him to sleep cool without having to buy a whole new mattress. This device uses a large blower under your bed to blast hot or cool air beneath your covers. If you like your existing mattress but find yourself sleeping hot, this could be just the ticket.

Sealy Cocoon Chill Memory Foam Mattress for $919: Its surface is noticeably cool to the touch thanks to its exclusive phase change material, which works wonders at drawing and storing the body’s heat. This all-foam mattress leans firm, making it well-suited for back and stomach sleepers. If you’re a side sleeper looking for more body contouring, I’d suggest looking elsewhere. If you’re a stomach sleeper looking for a firm mattress that’s also cooling, this one will do the trick. There was almost no motion transfer in my testing, allowing my husband and me to get up at different times without disturbing each other. —Nicole Kinning
Casper Snow Hybrid for $2,595: When you come across a mattress with a name that includes “snow,” your expectations for cooling effects are naturally high—and this mattress indeed lives up to that expectation. Structurally, this hybrid bed combines poly foam, memory foam, and pocketed coils, and provides targeted support at the hips, waist, and lower back to alleviate pressure, making it ideal for back and stomach sleepers. I noticed it came out of the box slightly misshapen from its packaging and emitted a faint plasticky scent. After about two days, the mattress was ready to go, the smell gone, and it had settled into its intended neat rectangle shape. —Nicole Kinning
Saatva Memory Foam Hybrid for $2,049: The Saatva Memory Foam Hybrid is marketed as firm, and that’s exactly what you should expect. Crafted with patented AirCradle memory foam, the mattress features concentrated cushioning in the center, strategically intended to support your lower back. Since I’m only 5’2,” the middle-back cushioning didn’t hit where it was intended to. Despite its firmness, I didn’t find this mattress particularly exceptional, especially with its cooling properties. Despite incorporating a triple-phase LuxeCool system and cooling gel-infused memory foam, the cooling effect didn’t stand out. —Nicole Kinning

Wayfair Sleep 12-Inch Medium Cooling Gel Memory Foam Mattress for $500: This bed has four layers of hypoallergenic gel memory foam infused with green tea, using cooling technology and a breathable design to ensure you’re having a super-cool sleep. This medium-plush bed has two top layers of gel-infused memory and comfort foam to help with breathability and cooling, and the top material is a breathable knitted cover to aid in airflow circulation. This mattress had the perfect balance of soft cooling with the memory foam, and the breathable knitted cover also helped with airflow. Most importantly, though, I always slept coolly on this sleeper hit (pun intended).
Wayfair 10.5-Inch Plush Cooling Gel Mattress for $536 (King): This cooling gel hybrid mattress comprises five layers of various memory foams. The memory foam pillow top aims to relieve pressure points and help reduce motion transfer, and it has a breathable knit cover to aid in the cooling effect. The mattress is compatible with an adjustable base and has a 100-night trial and 10-year warranty. Although it doesn’t have as noticeable a cooling effect as some others on this list, it’s a true plush mattress that uses cooling gel technology at an affordable price.
Wayfair Sleep 8-Inch Medium Cooling Gel Memory Foam for $400: This super-cheap medium-firm cooling mattress has eight total inches of memory foam—the top layer of cooling gel, charcoal, and green tea-infused memory foams (to aid in freshness and odor absorption), followed by a soft comfort foam on a durable high-density foam base. The top layer has a breathable, woven jacquard design that helps to keep the sleeper cool and reduces motion transfer. The layers of ultra-cooling gel and green tea-infused memory foams help with the cooling effect and keep any odors at bay. This super-inexpensive mattress delivers well above expectations, but there are better cooling options on our list.
Wayfair Sleep 14-Inch Plush Cooling Gel Hybrid Mattress for $326 (Full): This plush cooling gel mattress features a top plush layer of gel memory foam to relieve pressure and help with airflow, plus the quilted Euro-top knit cover and sides promote continuous airflow around the mattress to keep the sleeper cool. The bed also features classic pocket coils below for structure and support, with layers of memory foams surrounding the coils (this helps with low-motion transfer, too). The mattress is also compatible with an adjustable bed base, has solid edge support, offers a 100-night trial, and has a 10-year warranty. I love a plush mattress, but it may be too plush for someone with a bigger body, since the first super-soft memory foam layer is on top of a coil system.
Wayfair Sleep 13.5-Inch Medium Cooling Gel Memory Foam Mattress for $550: This 13.5-inch cooling gel memory foam mattress is listed as medium, but I’d definitely consider it super-plush. The top layer has 2 inches of gel-infused memory foam and 4.5 inches of comfort foam, and the bottom layer is 7 inches of high-density base support foam. Like other cooling Wayfair mattresses, the top has a breathable jacquard pattern and is green tea-infused to help with freshness and cooling. The top layers of memory foam are designed to mold to your body and help relieve pains and achy joints. This in-a-box bed also has low-motion transfer, a 100-night trial, and a limited 10-year warranty. If you’re someone who wants a super-plush bed that helps to wick moisture, then I’d recommend this behemoth.

How Does WIRED Test Cooling Mattresses?
Mattresses are tested for at least a week, but in many cases for longer. I slept on the majority of these mattresses for half a month or more to really get a feel for the product. I tested them at different times of the season and with different types of sheets and bedding. I sat on the edges to test for edge support, jumped, and performed some other methods to test the bounce and motion transfer of the mattress. Perhaps most important for this guide, I was my normal, perpetually warm (and sweaty) self, and gauged more abstract things like my overall comfort at night, and how well I thought air flowed through the mattress, or how much heat was trapped in.
What Should You Look for in a Cooling Mattress?
When shopping for a cooling mattress, here are a few things to consider:
- Composition: Opt for mattress materials designed to promote airflow, which will help prevent heat buildup. Many mattresses are infused with gel or copper, which are designed to dissipate heat and keep you cool. A hybrid mattress combines the best of both worlds by using a coil support system under a foam, latex, or polyfoam comfort top. Hybrid mattresses tend to retain less heat than all-foam mattresses because they have a layer or two of springs to help dissipate heat.
- Cover fabric: Consider mattresses with covers made from moisture-wicking fabrics and phase-change fibers to draw sweat away from the body. Breathable fabrics include bamboo, Tencel lyocell, and synthetic fabrics, which are engineered to help regulate body temperature. Perforated cooling covers further amplify airflow between your body and the fabric. We find quilted tops help too, since they have ridges and valleys that allow air to escape.
- Airflow: With proper airflow, the heat you generate overnight is properly conducted through the mattress. Hybrid mattresses with individual coils help with this, but many mattresses marketed for their cooling benefits have other tricks.
- Firmness: While the debate of soft versus firm mattresses is a personal preference, your choice can play a crucial role in the way your body traps heat. Softer mattresses tend to envelop your body, leading to increased heat retention as your body sinks into the surface. Conversely, firmer mattresses provide better support and allow for more air circulation around your body.
How Did WIRED Select Models to Be Reviewed?
We have tested over 100 mattresses across all of our guides, like Best Organic Mattresses, Best Mattresses for Back Pain, and Best Mattresses You Can Buy Online, as well as for individual review. We talk with each other, discussing which mattress brands in general we’re fans of, and which we aren’t. Some mattresses are provided as review samples by the manufacturers, with the understanding that we don’t guarantee coverage or type of coverage—we aren’t paid for glowing reviews on products we think are just mid. We purchase and expense models we aren’t able to get a sample of.
We try to test a range of mattress types, firmness, and brands to ensure we know what’s out on the market, so we can best give you our honest, unbiased opinion on which mattresses you should spend your money (and one-third of your life sleeping) on.
What Does WIRED Do With Mattresses After Testing?
We keep top picks for longer-term durability testing in our own homes and the homes of other staffers, friends, and family members, while other models are donated locally.

Every Model of this New Snoopy MoonSwatch Is Different—And You Can Only Get One When It Snows
First a confession: I own more MoonSwatches than I care to admit. Never let it be said that WIRED does not walk the walk when it comes to recommending products—Swatch has assiduously extracted a considerable amount of cash from me, all in $285 increments. This was no doubt the Swiss company’s dastardly plan all along, to lure us in, then, oh so gently, get watch fans hooked. The horological equivalent of boiling a frog. It’s worked, too—Swatch has, so far, netted hundreds of millions of dollars from MoonSwatch sales.
But while I’ve been a fan of the Omega X Swatch mashup since we reported on exactly how the hugely lucrative collaboration came to be in the first place, I have never liked the iterative Moonshine Gold versions. Employing a sliver of Omega’s exclusive 18K pale yellow gold alloy in marginally different ways on each design, they seemed almost cynical—a way of milking the MoonSwatch superfans on the hunt to complete the set.
Now, though, just when I thought I was done with MoonSwatch—having gone as far as to upgrade all of mine with official $45 color-matching rubber straps—Swatch has managed to ensnare me once again, and with a Moonshine Gold model: the new MoonSwatch Mission To Earthphase Moonshine Gold Cold Moon.
Clumsy moniker aside, this version takes the all-white 2024 Snoopy model (WIRED’s top pick of the entire collection), mixes it with the Earthphase MoonSwatches, and replaces the inferior original strap for a superior white and blue Swatch rubber velcro one. Aesthetically, it’s definitely a win, but this is not the Cold Moon’s party trick.
On each $450 Cold Moon MoonSwatch, a snowflake is lasered onto its Moonshine Gold moon phase indicator—and, just like a real snowflake, Swatch claims each one will be completely unique. When you consider the volumes of MoonSwatches Swatch produces each year, this is no mean feat.

These Are the Best Tech Deals to Shop This Cyber Monday
Welcome to WIRED’s guide to the best Cyber Monday tech deals, where we can promise you two things: these devices are worth buying (we’ve tested and recommended every one of them), and these are actual discounts (not the year-round price). So, whether you need an upgrade, want to treat yourself, or are seeking a great gift, we have you covered.
Want a wider range of deals? Check out the Absolute Best Black Friday Deals roundup to find more bargains this sale weekend.
Updated November 30: We’ve added deals on Samsung Galaxy Z Fold7 and Galaxy Z Flip7, Galaxy S25, S25+, S25 Ultra, Lenovo Flex 5i Chromebook Plus, Apple AirPods Pro 2, and Apple Watch SE 3.
The Google Pixel 10 is one of the best Android phones you can buy. Easy to recommend at full price, the Pixel 10 is an absolute bargain with this discount. You get an excellent triple-camera system with a 5X optical zoom sensor, support for Qi2 wireless charging, so you can magnetically attach to wireless chargers and docks, and Google’s super smart software features (Call Screen to filter out spam calls is our favorite). Learn more in the Best Pixel Phones guide.
The Pixel 9a is our top smartphone choice for most people, and it’s now $50 cheaper than it was on Black Friday itself. At $349, you’re getting a smooth-performing smartphone with a reliable dual-camera system that’s unmatched at this price, not to mention day-long battery life and a completely flat camera lens system for anyone who hates giant camera bumps. Oh, and it’ll get 7 years of software updates.
Sony’s A7 IV is the best mirrorless camera on the market (for most people). It’s a 33-megapixel, full-frame camera with a brilliant autofocus system, impressive dynamic range, and crisp images. There’s an expansive range of 4K video options as well, along with customizable buttons to set up your preferences, so you don’t have to always rummage through the menus. Reviewer Scott Gilbertson found the grip to be super comfortable and the camera to be light enough to endure for long periods without any back strain. —Boutayna Chokrane
If you’re shopping for open earbuds so that you can enjoy your music but still be aware of your surroundings, the Soundcore Aeroclip is the best we’ve tested so far. Reviewer Ryan Waniata praises the comfort, sound quality, usability, and value. The sound is wide and balanced, and the built-in controls are ideal for runs. Waniata likes to use them during outdoor activities, like hiking or biking, but he finds them especially helpful when he’s cooking dinner and needs to stay alert for his newborn’s cries. —Boutayna Chokrane
Editor Adrienne So says the Fitbit Ace LTE is the first fitness tracker she’s gotten her kids to use. It’s a fitness tracker (designed with Fitbit’s health sensors), gaming device, and location tracker. The $10/monthly subscription includes both LTE connectivity and Fitbit Arcade, which has a variety of movement-based games that get children on their feet and incentivize them to keep their watches on. They can call and text their guardians (and other approved contacts) through the Fitbit Ace app, and their location is trackable via Google Find My. —Boutayna Chokrane
This is a rare and tasty deal on my favorite Xmas lights. They work indoors or out, can be scheduled, and support a bunch of lovely animated effects. While I’m mentioning Philips Hue and its excellent but horribly expensive wares, you might want to check out some of its other Cyber Monday deals. My picks would be the wall washers ($316), TV lightstrip ($129), and HDMI sync box ($270).
The Asus RT-BE58U is perhaps the ideal Wi-Fi 7 upgrade for modest homes and apartments still struggling with the crappy router their internet service provider sent, and that’s why it tops our Best Wi-Fi Routers guide. It’s easy to set up and use, can cover up to 2,000 square feet, and boasts plenty of ports. As a dual-band router, it lacks the 6-GHz band, but has all the other advantages of Wi-Fi 7. There’s also support for VPN service, separate IoT or guest networks, and Ai Mesh.
Don’t ask me why they keep taking our ports away. God forbid you should want to plug something into your laptop. Well, you can stick it to those minimalist designers with the best laptop docking station. This one doubles as a wedge to prop your laptop up and has a storage slot.
These wireless noise-canceling headphones may not be the latest release from Sony, but they are still an excellent pair of cans with a far deeper discount. The Sony WH-1000XM5 are relatively light and comfortable, producing accomplished sound in every scenario, and have great control options.
You can spend a lot on a TV, but you can also get a great screen without breaking the bank, and the TCL QM6K proves it. This is the best TV for most people right now as it offers excellent color and processing, all the apps you want, and great performance, even in bright rooms. There are discounts across the range of screen sizes.
If you want to get the latest streaming apps on an older TV, the Roku Streaming Stick Plus is for you. It’s easy to set up, works reliably, and has a handy voice remote that makes finding content easier than ever. It slots neatly behind most TVs, and Roku’s interface is nice and clear.
Apple doesn’t really do sales, but other retailers do. This is the lowest price we’ve seen on a solid iPad the whole family can enjoy. The Apple iPad (A16, 2025) performs great for most tasks, looks pretty nice, and has a 12-megapixel camera. It is honestly all the iPad most folks need for surfing the web and streaming shows in bed. With iPadOS 26 and the new windowing apps feature, you can even comfortably do some work if you pair it with a Bluetooth keyboard and mouse.
Handy as they are for keeping you connected when your phone dies unexpectedly, portable chargers can be very same-y. The reason the Nimble Champ tops our Best Power Banks guide is Nimble’s focus on the environment. It’s made from 90 percent certified recycled plastic and comes in fully biodegradable packaging. It also works well, with capacities starting from 5,200 mAh, with USB-A and USB-C ports, and up to 15-watt charging.
Yes, you should read more, and Amazon’s Kindle e-readers make it easier to do exactly that. Our current favorite is the Kindle Paperwhite (12th generation). It has a sharp 7-inch display, auto-adjusting warm light, three-month battery life, snappy performance, and it’s slim and light, making it comfortable to hold. It even has integration with Overdrive for your library books and support for several languages.
The reMarkable 2 is one of the best digital notebooks, offering a paperlike writing experience, intuitive software, and several weeks of battery life. This is a budget model, so it lacks front light and color, but it’s still a decent device. Bundles where you choose both a marker and folio are heavily discounted right now, and they’re not often on sale, so it’s a good time to snap one up.
Keychron boards are popular here at WIRED, and the Q6 HE is our current pick of the best mechanical keyboards. Sturdy, satisfying to type on, with a lovely retro aesthetic, what more do you need? Well, the Q6 HE also boasts hot-swappable Hall Effect switches, four macro keys, and is relatively easy to customize or repair.
The great thing about Nomad’s 65-watt charger is that it’s incredibly slim, with flip-out prongs, so it can slip easily into small pockets in your bag or purse. You get dual USB-C ports, and can pull 45 watts out of the left port and 20 out of the right. Or, if you’re just charging one device, the full 65 watts is enough for any phone, most tablets, and even some MacBooks or Windows laptops (though they may not charge at top speed).
You know what I don’t miss in the slightest? Mowing the lawn. A good robot mower, like this relatively affordable one from newcomer Anthbot, will do it for you, quietly. No wire required; it recharges itself, you just set a schedule and relax. OK, it sometimes leaves a verge, but the only model I’ve tried that doesn’t is more than twice the price.
Sharp 2K video, color night vision, a wide 160-degree field of view, and clear two-way audio make the Arlo Pro 5S easy to recommend for folks seeking a security camera. You also get AI recognition for people and pets, a siren to scare intruders, and the quick-loading Arlo app. But you need Arlo Secure ($8 per month for one camera or $13 per month for unlimited cameras) for subject recognition, smart alerts, and cloud storage. The Arlo Pro 5S is our pick of the best outdoor security cameras.
I love my Oura Ring 4. It accurately tracks my sleep, activity, and stress levels and offers insights that I find genuinely useful. It’s also very comfortable, the app is super slick, with new features being added all the time, and it’s far less obtrusive than any other kind of tracker you could wear. The catch is a subscription, but this is still the best of the best smart rings.
It’s the thoughtful design that elevates the Backbone One above the rest of the best mobile controllers. Slot your phone into the compact cradle, with a USB-C jack for speedy connectivity, and you get satisfyingly clicky and responsive controls plus a 3.5-mm headphone port. You can also customize it for different games, or even use Backbone’s software as a one-stop gaming hub, if you’re willing to pay a subscription.
Yes, there is a new version of the Ray-Ban Meta Wayfarers, but the good news is that the old pair is now on sale. If you can stomach Meta AI’s privacy policies, there’s a strong argument that it has won the smart glasses race already (at least, so far). The best smart glasses must be easy to wear, and these look great and help offload things from your phone, so you don’t have to dip into that pocket quite as much.
The JBL Flip 7 is the Bluetooth speaker that has it all. It’s durable, it has stamina, it produces a punchy sound, and it comes in fun colors. As the best Bluetooth speaker you can buy, this deal is for real.
Toniebox is our favorite speaker for young kids, particularly ages three through seven. It’s essentially a squishy cube that plays stories and songs tied to different characters (aka Tonies). It’s activated when your child places the figurine on top of the speaker. There are so many Tonies to choose from. Peppa Pig, Moana, Winnie the Pooh, the list goes on. You can also buy Creative Tonies to record your own audio. Super easy to use, and the cutesy ears double as volume controls. —Boutayna Chokrane
The best tech books unpack the rise and fall of the characters that invented the stuff that runs our lives. The New York Times and former Wall Street Journal reporter John Carreyrou writes about Elizabeth Holmes, as she miserably fails to build a blood testing machine that would allegedly eliminate the need for hypodermic needles. Her company raised hundreds of millions of dollars, but its technology was inaccurate. Rather than admit defeat, she pressed on, which is why Holmes was put on trial for fraud and sentenced to 11 years in prison. —Boutayna Chokrane
Samsung’s flagship Galaxy S25 has been heavily discounted all Cyber Weekend, probably because its successors are right around the corner (the Galaxy S26 series is expected to be announced in January). But we still love these excellent smartphones. The S25 is the smallest, the S25+ gets a few extra perks, plus a bigger screen and better battery life, and the Galaxy S25 Ultra has a dual telephoto camera system, integrated S Pen stylus, and a beefy battery. Be sure to check out the Best Samsung Phones guide for the full scoop. —Molly Higgins
You’re not like other girls; you have a folding phone. In all seriousness, folding phones are not as fragile as they used to be, with durability improving while remaining slim. We love the Galaxy Z Fold7 because it’s amazingly slim and versatile. You can use the front screen like normal, and when you need extra real estate, open the device up. You can view apps on a much larger scale or easily split-screen two apps. If you’re not feeling a folding phone, the updated Galaxy Z Flip7 has a more usable front screen. Read our Best Folding Phones guide to decide which is best for you at the discounted price this Cyber Weekend. —Molly Higgins
The Lenovo Flex 5i Chromebook Plus is super cheap and compact, with a small touchscreen for more versatility. Especially with the Cyber Monday discount, it’s one of the most affordable Chromebook Plus models you can find, plus WIRED reviewer Luke Larsen thinks it’s in a whole different league over standard Chromebooks at this price because of its improved screen with a 360-degree hinge and touchscreen, fast performance, more storage, and crisp webcam. —Molly Higgins
Even though they’re an older model, we like these AirPods because of their hearing aid feature, comfort, and outstanding streaming experience. If you’re an iPhone user, you should have some AirPods, and we still think these are a good choice for most people because of their active noise cancellation, sound quality, and easy pairing within the Apple ecosystem. Plus, it doesn’t hurt that they’re nearly 25 percent off for Cyber Monday. —Molly Higgins
We on the WIRED Reviews team still think this is the best Apple Watch for most people. With its newest upgrade, it now has the latest S10 chip, a Liquid Glass display, Workout Buddy, and wrist-flick gestures. If you have an iPhone, this accessory is a no-brainer. It makes a great gift for yourself or others, and is seriously discounted at only $200 right now. —Molly Higgins

Dreaming of a Thuma Bed Frame? Don’t Miss the Black Friday Sale
Thuma knows what it’s doing when it comes to bed frames, which is why we’re so excited to see Thuma’s Black Friday deals. Two different frames from Thuma are the top picks in our Best Bed Frames guide, and our reviewers have reported how not only high-quality and and sturdy the brand’s frames are, but also how easy it is to put the frame together thanks to Japanese-style joinery.
While our top pick isn’t on sale, our second-favorite is on Thuma’s site during this Black Friday weekend, and it’s a great price for the quality you’ll get. And it’s not the only thing Thuma has on sale, either, if you’re looking for more Thuma goodness around your bedroom and home.
If you’re looking for more great sleep deals, don’t miss our guide to the Best Black Friday Mattress and Bedding Deals, plus you can catch more sleep deals on our guide to the Absolute Best Black Friday Deals.
The Best Thuma Bed Frame Deal
Thuma’s Signature Bed is one of our all-time favorite bed frames. It’s on the new side, launching back in February as Thuma’s first upholstered bed. It still uses Japanese wood joinery, but the frame is covered in two different fabric options, depending on what you choose. There’s a soft Italian felted wool and a performance linen; our reviewer tested the wool version for a few months with great results.
Even with the fabric covering, it still only takes minutes to assemble this bed, and there’s not a squeak to be heard since it was built. WIRED reviewer Martin Cizmar says the plush headboard feels pillow-soft, so much so that he’s tempted to try to lie directly on it. The frame can come with or without a headboard, and both variants are on sale right now.
If it’s still out of your budget, check out our guide to the Best Thuma Dupes to see if any on-sale options are a fit for you. But there’s really no better time to get a Thuma frame of your own than during this sale, especially since we’re such big fans of this model.
