Looking for Softer Sheets? These Bamboo Sheets Are the Answer
Comparing Our Favorite Bamboo Bedding
Terminology to Know When Shopping
Confused by the terms used to describe bamboo bedding? Here’s a quick breakdown.
Bamboo type: You’ll see bamboo rayon, viscose, or lyocell listed for the bamboo, which explains what method was used for turning the bamboo into fibers that could become sheets. Rayon is the cheapest, while viscose is a slightly better production process, and lyocell is the most ideal process (but still not a perfect one, and usually the most expensive).
Certifications: Some companies will label bamboo sheets as organic, using certifications like Oeko-Tex. You can learn more about organic certification terms here to understand what they each mean, and our thoughts on organic bamboo in our FAQs below. You might also see FSC-certified, which means it was sourced through sustainable forests certified by the Forest Stewardship Council.
Honorable Mentions
Cariloha Classic Bamboo Sheets for $239: Cariloha’s Classic Bamboo Sheets have a twill weave, which has a diagonal thread pattern and doesn’t sound as soft as a sateen weave that has a three-over-one pattern. But these sheets still felt super soft, and the softness difference compared to the pricier Retreat Sheets ($339) was minor for such a big price difference. There’s no corner straps, though.
Cariloha Retreat Bamboo Sheets for $339: These sheets are super soft and silky and use lyocell fabric to be more sustainable. They’re a similar softness to the brand’s cheaper sheets, but if you want to prioritize eco-friendly sheets, lyocell is a good option (though not a perfect carbon-neutral solution). I also really like the included straps, but you can find those on cheaper sets like the Luxome sheets I recommend above.
Ettitude Luxe Sheet Set for $470: These sheets are fantastically soft and use a combination of bamboo lyocell and bamboo “biochar” to make them antifungal and odor-resistant. They ran a little warm for my liking, but if you’re looking for something to keep odors and fungi away, these could be the splurge for you. Ettitude previously called these Airy+ instead of Luxe, but both use a combination of lyocell and biochar.
Honeydew Sheets for $230: These sheets felt a little stiff at first but softened up a bunch after washing. They also come with a securing strap, so they’re a good option for taller mattresses. The only downside is that they’re only available in two colors, but if you want white or a nice dark gray, you’re in luck.
My Sheets Rock the Regulator Sheet Set for $199: These sheets are super soft. They promise to regulate your temperature, but I found myself waking up a little too warm some nights. If you aren’t a hot sleeper, these are overall soft, comfortable sheets to sleep on.
Pom Pom at Home Bamboo Sateen Sheet Set for $368: These are good bamboo sheets, but for the price, we were more impressed by others we tested.
Quince Linen Bamboo Bundle for $255: This set would have been a pick if it were still available. It’s a fantastic combination of linen and bamboo that gets the best of both worlds: the softness and cool touch of bamboo with the structure and airflow of linen. It’s a great pick for hot sleepers—if it resurfaces, buy it!
Quince Bamboo Sheet Set for $130: Quince makes some solid sheets, and these bamboo ones are super soft. They’re a little heavy for me as a hot sleeper, but otherwise come in a nice range of colors and have an Oeko-Tex certification, meaning no harmful chemicals were used. Quince also says the bamboo is organic, but there aren’t any certifications to confirm that (more below on our thoughts on organic bamboo bedding).
Sunday Citizen Bamboo Sheet Set for $109: WIRED reviewer Louryn Strampe found these sheets to be super soft and fantastic to sleep on. But even with the claimed deep pockets, they tended to pop off her mattress, and other picks like Luxome’s sheets feature straps that will avoid that problem.
FAQs
What Types of Bamboo Are There?
There’s a few different terms you might see when describing the bamboo fibers that make up a set of bamboo sheets. Bamboo isn’t naturally a soft fiber, so it goes through a harsh chemical process to break it down and turn it into fibers that can be woven into sheets. Each different name lets you know what kind of process was used and what kind of chemicals (and chemical off-put) were involved.
Bamboo rayon and bamboo viscose are sometimes used interchangeably, though they shouldn’t be since they aren’t exactly the same. Rayon is likely a term you’ve seen before, since it’s a general term used for fabric made from regenerated cellulose. Bamboo rayon usually suggests that it’s semi-synthetic and might not be 100 percent bamboo. Meanwhile, bamboo viscose also uses bamboo cellulose as its base, though it has a slightly different process. Viscose is another type that isn’t limited to bamboo. Just about every sheet I’ve tested claims to be 100 percent bamboo viscose.
Bamboo lyocell is the best of the three, because lyocell has a closed-loop process, which means that almost all of the chemicals used to make more lyocell get reused rather than dumped. Lyocell is a fantastic-quality fabric that makes for a great cooling sheet, so it’s a term to look for if you want to stay cool while you sleep.
Are Bamboo Sheets Cooling?
While bamboo is absolutely cool to the touch when you first climb into bed, I often find that bamboo bed sheets can warm up quite a bit throughout the night. Some companies claim that the bamboo fibers can help regulate your temperature and wick away moisture. As a hot sleeper, I haven’t found this true with every set of bamboo sheets. Some have a weave that’s too heavy to keep me cool on hot nights, since no amount of promised moisture-wicking can replace good airflow to keep you cool. There are a few sets of bamboo bed sheets I recommend below that keep me cooler than others, but I recommend visiting our guide to the Best Cooling Sheets if you want to consider all kinds of bed sheets that could keep you cool, from bamboo to cotton percale and even sheets with phase-change material (or PCM) blended in.
Can Bamboo Sheets Be Organic?
Unlike cotton fabrics, which have the Global Organic Textiles Standard or GOTS, there’s no overarching certification to verify if bamboo is organically sourced. Many sheet makers will say the bamboo is organic, but with no main certification to confirm this, it’s hard to say without a doubt that any bamboo sheets are fully organic.
Instead, you’ll usually see Oeko-Tex certifications, which confirm that no harmful substances were used, and sometimes you’ll see Forest Stewardship Council or FSC certifications, which confirm the bamboo was sustainably sourced. Hopefully a primary bamboo organic certification will come out in the future to better inform bamboo textile shoppers. You can learn more about existing organic certifications in our guide here.
Does Thread Count Matter?
Bamboo sheets have a thread count, just like cotton sheets, describing how many threads are in a square inch of the fabric. You don’t want too high of a thread count—anything over 800 is purely marketing-speak, and higher thread counts can mean shorter, lower-quality fibers. It’s better to have fewer fibers that are longer and stronger.
Bamboo made into rayon, viscose, and lyocell can be manipulated into a long thread more easily than cotton, of course, so we haven’t seen the crazy-high thread counts listed on bamboo sheets. Many of these sheets are also a sateen weave, which is a three-over-one thread style, leading it to feel softer but not be as breathable. It’s not always so simple as sateen will make you hot, of course; our favorite cooling bamboo sheets from Ettitude have a sateen weave, so it depends on several factors.
The takeaway? Don’t worry about thread count. Focus on type of weave and reviews (like ours!) to get a better idea of whether a set of bamboo sheets (or any other kind of sheet) will suit your sleep needs.
How Does WIRED Test Bamboo Sheets?
For our bamboo sheets guide, I compared our picks both overnight and side by side for softness, cooling properties, and price. Each set of sheets was slept on anywhere between two and seven nights, depending on how it performed, and was washed multiple times to check for pilling or design flaws. I’m a hot sleeper living in Southern California, with my bedroom on the third floor of my home, so it’s been easy to discover if sheets can’t keep me cool all night long. I also looked at each sheet’s quality in reference to the price to see what sheet sets were really worth investing in after testing each one.
How Does WIRED Obtain Sheet Samples? What Happens to Samples After Testing?
All sheets in this guide were obtained as testing samples from companies. We obtain these sheets with no obligation to cover or promises for what coverage could look like. When testing is complete, the top picks are held onto for long-term testing, while the rest are donated locally.

The Catastrophic Swatch x Audemars Piguet Launch Was Entirely Predictable and Utterly Avoidable
The note from the communications team then, quite remarkably, lists some stats in an attempt to paint the launch in a positive light, as opposed the retail bin-fire it seemingly was: “We have received millions of clicks on our website. This new collaboration is literally making social media explode, with over 6 billion views within one week; by now, it is already 11 billion. All in all, the Royal Pop Collection is captivating the entire world, not least because the Royal Pop is, quite surprisingly, not a wristwatch.”
Audemars Piguet seems unhappy with how Swatch has handled the launch of its collaboration on the Royal Pop. AP told WIRED that “we understand the questions around the Royal Pop launch experience. As retail operations are handled by Swatch and their local teams, Swatch is best placed to comment on the operational handling of the launch. From AP’s perspective, safety and a positive experience for clients and teams remain the priority.” The brand did not respond when asked if it considered Swatch’s handling of the Royal Pop launch a “safe and positive experience”.
The madness of the Royal Pop launch is that, considering all that could have been learned from the MoonSwatch release in 2022, Swatch decided to repeat the playbook that went so badly wrong four years ago. This is a move, according to experts, that was entirely avoidable and utterly unnecessary.
Hype With No Control
“Luxury drops cannot rely on surprise, scarcity and social frenzy as the strategy, then act surprised when human behaviour follows,” says Kate Hardcastle, author of The Science of Shopping and advisor to brands including Disney, Mastercard, Klarna and American Express. “Retailers are already dealing with heightened tensions around theft, aggression and crowd management globally. Add a highly restricted product, long queues, resale economics, social media amplification and the emotional intensity attached to luxury access, and the environment can escalate very quickly if not expertly managed.”
Hardcastle confirms that what is particularly difficult for Swatch here is that the MoonSwatch launch already provided a live blueprint of the risks. “Once a brand has experienced scenes involving crowd surges, disappointment and policing,” she says, “the obligation shifts from reacting to proactively engineering a safer customer experience. Successful luxury houses increasingly control the experience with far greater precision.”
Neil Saunders, managing director of retail at Global Data, is even more candid. “The chaos does not reflect well on Swatch, and it probably makes Audemars Piguet wonder what on Earth it has gotten itself into,” he says. “Wanting to create some hype is understandable, but not being able to control it becomes damaging both commercially and for the brand image. Swatch should understand this better than most as it has been through this before with MoonSwatch.”
Not only Saunders and Hardcastle, but scores of commenters on Swatch’s Instagram post, point out well-known and obvious solutions that would have mitigated or entirely avoided the Royal Pop’s shambolic release.
“We have seen other premium or limited launches use staggered collection windows, verified appointment systems, geo-ticketing, VIP allocation tiers, timed QR access, private client previews and controlled queue technology to reduce volatility while preserving excitement,” says Hardcastle, adding that some combine digital ballots with curated in-store experiences so consumers feel part of an occasion rather than participants in a scramble.

The Backward Logic of Chickenpox Parties
Anyone who has had chickenpox shares one distinct memory: the relentless, all-consuming itch.
Ciara DiVita was only 3 years old when she caught the virus, but she remembers it well—along with the oven mitts she was made to wear to stop herself scratching. She also recalls being taken to hang out with her cousin while covered in blisters, in the hopes of deliberately infecting them.
DiVita, now 30, was actually the second in the chain, having been taken by her parents to catch chickenpox from an infectious friend. “I imagine the chain continued and my cousin gave it to someone else at a chickenpox play date,” she says.
A lot has changed over the past three decades, most notably the development of a chickenpox vaccine, meaning the virus is no longer the childhood rite of passage it once was.
Thanks to the vaccine’s success, children today are much less likely to be exposed to the infection at school or on the playground.
Chickenpox parties are also largely considered a relic of the past—a strategy many Gen X and millennial children were subjected to before vaccines became routine. But much like the virus itself—latent, opportunistic—they haven’t disappeared entirely.
Before a vaccine existed, chickenpox, which is caused by the varicella-zoster virus, felt unavoidable. In temperate countries like the UK and the US, around 90 percent of children caught the virus before adolescence (in tropical countries the average age of infection is higher).
It’s nothing to do with chickens. The splotchy, scratchy, highly contagious disease is possibly named after the French word for chickpea, pois chiche, according to one theory, because the round bumps caused by the virus resemble their size and shape. While most infant cases are mild, adolescents and adults are more likely to develop severe complications.
This is where the idea of “getting it over and done with” emerged from, according to Maureen Tierney, associate dean of clinical research and public health at Creighton University in Omaha, Nebraska.
“You were trying to have your child get the disease when they were at the greatest chance of not having complications,” Tierney says, explaining that, generally speaking, the older the patient, the more severe the infection can be.
While varicella-zoster is usually a mild, self-limiting disease in children, it can be much more severe—and sometimes life-threatening—in adults.
“I had an otherwise healthy adult patient who died of chickenpox pneumonia when I was first practicing,” Tierney says. “You never forget those scenarios.”
The virus spreads rapidly through respiratory droplets and contact with fluid from its characteristic blisters, meaning if one child contracts it, siblings and classmates are likely to be next, if unvaccinated.
Before the existence of social media, the idea that children should deliberately infect each other spread just as rapidly around communities—in conversations in the school yard, church groups, and pediatric waiting rooms—leading to the popularity of so-called chickenpox parties.
Parents swapped advice about oatmeal baths and calamine lotion and arranged to bring children together when one was thought to be infectious—despite the practice never being an official medical recommendation.
“They thought, well, if it’s going to happen to my kid anyway, it might as well happen in a controlled environment,” says Monica Abdelnour, a pediatric infectious disease specialist at Phoenix Children’s Hospital. “The families were ready to encounter this infection, deal with it, and then move on.”
While the majority of children who develop chickenpox feel well again within a week or two, around three in every 1,000 infected experience a severe complication such as pneumonia, serious bacterial skin infections, encephalitis (inflammation of the brain), or meningitis.

A Danish Couple’s Maverick African Research Finds Its Moment in RFK Jr.’s Vaccine Policy
In 1996, Guinea-Bissau seemed like an ideal research post for budding pediatrician Lone Graff Stensballe. Her supervisor, a fellow Dane named Peter Aaby, had spent nearly two decades collecting data on 100,000 people living in the mud brick homes of the West African country’s capital.
Aaby and his partner, Christine Stabell Benn, believed that the years of research in the impoverished country had yielded a major discovery about vaccines—and what they described as “non-specific effects”: The measles and tuberculosis vaccines, which were derived from live, weakened viruses and bacteria, they said, boosted child survival beyond protecting against those particular pathogens.
But, the scientists said, shots made from deactivated whole germs, or pieces of them, such as the diphtheria-tetanus-pertussis (DTP) shot, caused more deaths—especially in little girls—than getting no vaccine at all.
The World Health Organization repeatedly and inconclusively examined these astonishing findings. They tended to elicit shrugs from other global health researchers, who found Aaby’s research techniques unusual and his results generally impossible to replicate.
Then came Donald Trump, Covid, and the administrative reign of anti-vaccine advocate Robert F. Kennedy Jr.
Suddenly, Aaby and Benn weren’t just sending up distant smoke signals from a far corner of the planet. They were confidently voicing their views and policy prescriptions online and in medical journals. The “framework” for “testing, approving, and regulating vaccines needs to be updated to accommodate non-specific effects,” their team wrote in a 2023 review.
And the Trump administration has taken notice.
“They became more strident in saying that their findings were real and that the world needed to do something about it,” said Kathryn Edwards, a Vanderbilt University vaccinologist who has been aware of Aaby’s work since the 1990s. “And they became more aligned with RFK.”
Kennedy, as secretary of the Department of Health and Human Services, cited one of Aaby’s papers to justify slashing $2.6 billion in US support for Gavi, a global alliance of vaccination initiatives. The cut could result in 1.2 million preventable deaths over five years in the world’s poorest countries, the nonprofit agency has estimated. Kennedy has frozen $600 million in current Gavi funding over largely debunked vaccine safety claims.
Kennedy described the 2017 paper as a “landmark study” by “five highly regarded mainstream vaccine experts” that found that girls who received a diphtheria-tetanus-pertussis, or DTP, shot were 10 times more likely to die from all causes than unvaccinated children.
In fact, the study was far too small to confidently make such assertions, as Benn acknowledged. In a study of historical data that included 535 girls, four of those vaccinated against DTP in a three-month period of infancy died of unrelated causes, while one unvaccinated girl died during that period. A follow-up published by the same group in 2022 found that the DTP shot by itself had no effect on mortality. Critics say the 2017 study, rather than being a landmark, exemplified the troubling shortfalls they perceive in the Danish team’s research.
As Aaby and Benn’s US profile has risen, scientists in Denmark have set upon the work of their compatriots. In news and journal articles published over the past 18 months, Danish statisticians and infectious disease experts have said the duo’s methods were unorthodox, even shoddy, and were structured to support preconceived views. A national scientific board is investigating their work.
Stensballe, who worked with Aaby and Benn for 20 years, has been among those voicing doubts.
“It took years to see what I see clearly today, that there is a strange concerning pattern in their work,” Stensballe said in a phone interview from Copenhagen, where she treats children at Rigshospitalet, the city’s largest teaching hospital. She said their work is full of confirmation bias—favoring interpretations that fit their hypotheses.
