I test bedding for a living, and this Cozy Earth duvet cover is pure luxury — save 35% with our exclusive Sleep Week code

In the spirit of Sleep Awareness Week, I have a confession: Despite the fact that I test and write about home products for a living, I've never been the type of person who looks forward to going to bed. Maybe it's because I'm a hot sleeper and used to find myself drenched in sweat in the middle of the night — not exactly pleasant! But ever since I started sleeping under this ethereally silky Cozy Earth Bamboo Duvet Cover, all of that has changed. It manages to keep me cool and, true to its name, incredibly cozy at the same time. (No wonder Oprah loves this brand!) This luxurious duvet cover costs a pretty penny, but good news: It's on sale for Sleep Week 2024.

Why do I need this?

The Cozy Earth Bamboo Duvet Cover is made of 100% viscose from bamboo fabric, which is known for its temperature-regulating properties. For a hot sleeper like me, this is a game-changer; even though I tend to sweat at night, I like the comforting feeling of being covered by a blanket.

Before I switched to this duvet cover, I was sleeping under a stuffy cotton-blend comforter that I often wound up kicking off in the middle of the night. But the Cozy Earth cover feels cool to the touch in a way that's refreshing without making me cold. With my comforter inside, it's got a bit of heft for a sort of "hugging" sensation (so comfy), but it feels far less heavy than a true weighted blanket.

Placing a comforter inside a duvet cover is never fun, but this one has ample snaps inside to help keep everything in place until laundry day. I will say that the version I have has a series of tie enclosures at one end, and because of the slippery material, they can become untied fairly easily — a pro when you need to take the comforter out, but a a nuisance when you want them to stay closed. (Reviewers who have purchased this duvet cover more recently note that theirs have zip-up enclosures.)

Aside from that, the snaps ensure my comforter stays put without bunching or migrating, and the satin-like material has elevated the look of my bed beyond recognition. Now I feel like I'm in a fancy hotel bed when I get under the covers, and I can "rest" assured I won't wake up a sweaty mess.

Cleaning this duvet cover is a breeze too — it's machine washable, and while it does wrinkle easily, tossing it in the dryer remedies that.

What reviewers say

With over 900 reviews, the Cozy Earth Bamboo Duvet Cover has scored an impressive 4.9-star average rating.

"We love the simple look of this well-thought-out duvet cover," raved one satisfied sleeper. "It washes well and did not need ironing when put straight on the bed out of the dryer. ... We do have a cat, and I’ve noticed we don’t have fur sticking to the cover either, which is amazing!"

"It is so soft and comfortable, I feel like I am sleeping in clouds," said another happy shopper. "Cozy Earth is 100% the best bamboo products on the market! Trust me, I have tried several. ... It has made menopause an easy transition. I no longer wake up sweating."

"My boys used to sweat all night long," shared a pleased parent. "Now they both have a good night's sleep with the duvet that keeps them not too cold or hot. This is saving our laundry machines, water, electricity bills!"

This final fan's only complaint? "My current comforter doesn't want to 'stay' in the corners — the snap holders must work well with the Cozy Earth comforter, but not my current comforter. That's the only drawback: I need to shift the comforter and reset it inside the cover each morning." (Psst: I use this affordable Bedsure comforter with my duvet cover and it stays in place just fine. Here's my full review.)

While we're on the subject of bedding, need some new sheets? Cozy Earth has also discounted Oprah's favorite bamboo sheet set.

"Truly the most luxuriously soft sheets I have ever had!" gushed a reviewer. "I sleep like a baby with these sheets, enveloped in softness all night long. I cannot wait for summer … these sheets have a slight coolness to them, which I know will bring even more amazing sleeps when the heat kicks in."
