- Casper is known first and foremost for its mattresses, but it has also expanded into making bedding products like sheets and pillows.
- I tried a selection of their new line and was rewarded with a comfortable sleep experience: The cotton sheets are cool and crisp, the duvet cover is weighty and well-designed, and the pillow is soft yet supportive.
- From a mattress-first company, the bedding is impressively good and offered at a reasonable price, too.
When shopping for bedding, I tend to look for the brands that make it their core business and have been producing it for years — but when I heard about mattress start-up Casper's foray into bedding, I was intrigued. At $129, its queen-sized sheet set sits between the value-focused Brooklinen and $200+ options from Parachute, Boll & Branch, and Snowe, so purely based on price, it seemed to strike a good balance. Since Casper clearly has an understanding of the mattresses people like to sleep on, I hoped that it could also perfect the bedding that goes over that mattress.
I tried Casper's sheets, duvet cover, and pillow, and after many nights of great sleep, I can now count its bedding products among my favorites. Below, I break down how this mattress-first company won me over with its bedding.
The sheets
The sheet set comes with one flat sheet, one fitted sheet, and two standard pillowcases (one pillowcase for twin/twin XL sizes). It's available in six cool-toned combinations of white, blue, and slate gray. I opted for the white/slate color because I wanted the clean, neutral look of a hotel room, but not the sterility of an all-white ensemble.
I encountered no problems changing into these sheets. The thick stretchy elastic on the inside of the fitted sheet is rubberized, letting it grip onto the mattress and leaving little room for the sheets to move around.
I found that while it was just slightly big, it wasn't enough to bother me and Casper says the extra fabric is to account for the industry-standard two percent shrink factor. If you'd like, you can wash the sheets before your first use. As for the flat sheet, my personal preference is to not sleep with one, but if my experience with the fitted sheet and pillowcases are any indication, the flat sheet should be equally enjoyable to sleep with.
The sheet set is made from extra-long staple Supima cotton, which represents less than 1% of cotton grown in the world. These long continuous fibers are stronger and softer than the shorter fibers of regular cotton, resulting in longer-lasting, piling-resistant, and comfortable sheets that are certainly worth the investment. Meanwhile, the percale weave — a standard one-yarn-over, one-yarn-under weave — is what gives the sheets their crisp, cool feel. They're perfect for the summer and warmer climates, or if you tend to overheat in your sleep.
The duvet cover
For an additional $90 to $140, you can add a matching duvet cover to your sheet set, and we highly recommend you do so. Insider Picks senior editor Ellen Hoffman, who also tested the sheets and cover set, can't praise it enough for its superior design details that solve for the annoying inconveniences of typical duvet covers. There's no way you'll button up the wrong buttons and have to start all over again because there are no buttons, just a zipper and snaps in the corners. And if your duvet shifts around inside, there are hidden openings that let you readjust the duvet without having to undo the whole cover.
The cover is not overpoweringly heavy at all but still has that soothing weight you appreciate at the end of the day. It's probably too warm for the summer, but for the remaining chilly nights of the year, it does the job well.
The pillow
I sleep on a memory foam pillow that's on the firmer side, so I can usually expect an adjustment period of at least one night whenever I try out new pillows. To my surprise and delight, I settled immediately into Casper's pillow.
My theory for this seamless transition is the pillow's two-layer construction, which strikes the balance between firmness and softness that most sleepers are looking for. The inner pillow provides a foundation of firm support, while the outer pillow is soft and fluffy.
Filled with polyester microfiber and covered by a 100% cotton percale weave fabric, it adapted to my movements and always stayed cool throughout the night. The pillow is also easy to clean: just unzip the outer pillow, remove the inner pillow, and throw both in the washing machine.
