Don't sweat it: Cozy Earth bed sheets
Like slipping into a shady hammock on a July afternoon, Cozy Earth’s Bamboo Sheet Set was made for cool comfort with a smooth touch. The fabric is 100% viscose from bamboo in a sateen weave. Unlike most other sheets, pockets fit mattresses up to about twenty inches so sheets stay tucked in even if you're using a fluffy mattress topper. Sets include two pillowcases, one fitted sheet, and one flat sheet, with the split king trading the fitted sheet for two twin XLs. The color palette ranges from crisp white and soft neutrals to walnut and pacific blue, with new pinstripe options that work well in both traditional and modern bedrooms. Oprah included the set in her Favorite Things list back in 2018, calling it the softest ever.
At a glance
Cozy Earth was founded by laid-back surfer Tyler Howells in 2010 to help solve the wife/husband temperature feud that often accompanies pregnancy, and they have focused on bamboo-based bedding and loungewear since the start. The sheet set is their flagship, and it is built around temperature regulation and an intentionally generous cut. Each piece is OEKO-TEX Standard 100 certified, so it meets third-party safety standards for harmful substances unlike some of the sketchy sheet sets out there. Unsure if these sheets are for you? Buyers get a 100-night trial and a 10-year warranty for peace of mind.
Why bamboo?
Bamboo-based viscose sits in the “regenerated cellulose” family, alongside lyocell. It feels smoother than most cotton because of the rounder fibers and a silky drape. It also absorbs more moisture vapor, which matters for breathability and sweat control. Viscose averages about 11% moisture regain, cotton is closer to 8%, and polyester sits near zero. That explains why synthetics feel clammy and build static. The tradeoff is durability. While these sheets will last, viscose does some strength when wet and benefits from gentle washing. The surface of bamboo fabric is naturally smooth, which reduces friction and can help people with sensitive skin avoid irritation compared to rougher cotton weaves. It also tends to resist pilling longer than cotton, which means the fabric keeps its clean look after repeated washes.
What’s in the set
The construction is consistent across sizes. Twin and twin XL include one pillowcase, full through king include two, and king or larger sets use king-sized pillowcases. The split king comes with two twin XL fitted sheets instead of one, plus a shared flat sheet and two king pillowcases. Deep pockets stretch to around twenty inches, which is helpful for anyone with a tall mattress topper.
Feel, cooling, and sweat handling
The sateen weave gives the sheets a smooth surface and fluid drape, meaning the fabric gently flows over contours rather than closely following them. This makes air pockets that create just the right balance between 'comfortable' and 'cold'. These sheets work well for sweaty sleepers because the fibers wick moisture away before the surface feels damp, and they have room between contact points to naturally move the moisture away and dry quickly where areas do not have physical contact. Architectural Digest recently named Cozy Earth the best overall deep pocket sheet set, praising both comfort and secure fit.
Seasonality and static
One reason viscose is popular is that it is comfortable year-round. In summer the sheets feel breathable, and in winter they insulate lightly without becoming heavy. Unlike polyester, static is uncommon because the fiber naturally retains some moisture from the air. Over-drying can cause cling in particularly dry climates, but reducing dryer heat or using wool dryer balls usually prevents it. We think it is best to use cooler sheets all year long to wick away sweat and let the desired warmth in winter months come from the comforter.
Care and durability
Care instructions are straightforward: machine wash cold, no bleach or softener, and tumble dry low or regular. Cozy Earth suggests wool dryer balls instead of dryer sheets to keep the fabric smooth because it doesn't leave behind a chemical coating that can cause skin irritations and reduce breathability. Like other bamboo viscose fabrics, these sheets are more delicate when wet, so avoiding high heat extends lifespan. Viscose is similar to almost all other sheets in that it does not have any anti-microbial properties, so frequent laundering remains the best way to keep bedding fresh. These sheets stand up even if laundered often, and Cozy Earth is known for their long warranty and they stand behind their claims.
Colors and pinstripes
Cozy Earth offers more color options than most competitors with shades like light grey, oat, driftwood, charcoal, walnut, creme, shore, dove grey, pacific blue, and peony, along with new driftwood and charcoal pinstripes. The pinstripe patterns are subtle enough to blend into minimalist spaces but add variety compared to plain solids.
Endorsements that matter
The sheet set has been consistently praised by everyone who has reviewed them. Oprah’s 2018 Favorite Things list included them, calling the sheets ideal for both hot sleepers and chilly ones. Architectural Digest recently highlighted it as the best deep-pocket sheet for comfort and fit, proving that these sheets are still the same quality as they were when Oprah endorsed them. Business Insider listed them as the “splurge” choice in its bamboo roundup and pointed to the mix of softness and durability.
Vetted verdict
Cozy Earth’s Bamboo Sheet Set may not be the cheapest option but it balances comfort, fit, and durability better than anyone else. The deep pockets solve the problem of corners slipping off tall beds, the hand is soft without being slippery, and the year-round breathability works for sweaty or neutral sleepers. A little extra care needs to be taken in laundering, but the instructions are simple. For premium feel and fit combined with long warranty and heavy-hitting endorsements, Cozy Earth is a no-brainer.
