The Casper sheets are the perfect balance of soft, crisp, and airy.


Casper was created to re-imagine sleep from the ground up, beginning with its obsessively engineered, outrageously comfortable mattress. All of Casper’s sleep products are developed in-house by the company’s award-winning R&D team, including its airy sheets, pillow-in-a-pillow, and inventive Lounger and Layer designed exclusively for Target.

Casper was recently named one of Fast Company's Most Innovative Companies in the World and its eponymous mattress was crowned one of TIME Magazine's Best Inventions.


What is Supima® or Pima cotton?
Pima cotton is one of the longest cotton fibers in the world. It’s 35% longer and 45% stronger than regular cottons, which means the fiber won’t pill or tear — it will only get softer and more lustrous wash after wash. Supima® is a trademarked name for textiles woven from 100% American Pima cotton, which is only grown in Texas and California. The Pima cotton used in Casper sheets comes from a farm in California’s Central Valley.

What's the thread count of the Casper sheets?
The thread count (400, with ultra-fine 2-ply 80s yarn) balances strength and softness without compromising breathability.

Will Casper sheets only fit on a Casper mattress?
You definitely don’t need a Casper mattress to use Casper’s one perfect sheet set! Any mattress up to 14” deep will work.

How do you care for the Casper sheets?
Wash in cold water on a gentle cycle and tumble dry on low. To prevent your sheets from wrinkling, remove from the dryer as soon as possible.

What is the 100-Night Trial?
We believe you should actually sleep on a product to decide if you like it. So we give you 100 nights to test out all Casper products in your own home. If you don’t love it, we’ll give you a full refund.

These sheets are Supima cotton - one step down from true Egyptian cotton which is used in much more costly bed linens. Both in a percale weave rather than satin are more subject to wrinkling. However, percale wears better and is cooler. Because of this, I chose Casper. I find the fabric is soft enou...see moreof the reviewer's review

These sheets are great. they are easy to put on my King size bed by myself. The best thing about them is they DO keep you COOL!!!! I always end up with my sweaty 5 year old next to me in my bed and he usually soaks through the sheets! Not this time! These are keeping us all cooler.

Really smooth and high quality fabric. There are little touches that make it stand out besides the fabric quality. The mattress cover has these grippy elastic bands which help keep it in place and is constructed from 5 separate pieces of fabric so its an actual box shape that fits the mattress bette...see moreof the reviewer's review

We wanted cool, crisp sheets, not soft, slippery ones. In this, we were apparently unlike most people! Truly crisp sheets are hard to find. These sheets fit well, don't come untucked or wrinkle up at night, and remain crisp. They are expensive, no question. We used some gift cards to make them ...see moreof the reviewer's review

Best sheets I've had. We got "free" $180 sheets with our new mattress and we haven't touched them since we got these. With an adjustable bed frame, our sheets were popping off when we raised the head of the bed, even with sheet straps. The very deep pockets and strong elastic all the way around the ...see moreof the reviewer's review
