More than just dressing for your mattress and pillows, the right set of sheets can transform your bedroom and every night of your life.

However, most sheet sets represent a compromise between softness, strength, and breathability.

We spent 18 months visiting 10 factories on 3 continents to test hundreds of samples in order to design a sheet set that perfectly balances them all.

Sublime Balance

The Casper sheets offer the perfect balance of softness, breathability, and strength — three of the most desired sheet attributes.

Casper Illustration (Balance)
Casper Illustration (Cotton)

The best cotton

Our unique design is made possible by some of the best cotton fibers in the world — and it just so happens they’re grown in California. We use a sustainably grown, extra-long staple Supima® cotton. The longer the fiber, the stronger the yarn, which means less tearing over time and softness that lasts.
Casper Illustration (Strong Weave)

Strongest Weave

Compared to sateen, our percale weave is more structurally sound, breathable, and durable, giving you cool, crisp comfort for nights on end.
Casper Illustration (Thread Count)

Smart thread count

To get the most out of our top-quality threads and weave, we needed to find the perfect thread count. Most people think “the more, the fancier,” but that’s only true until there are so many threads that they block airflow. After testing dozens of combinations, we found that a thread count of 400 (200, using 2-ply threads) provides the ideal balance between soft, strong, and breathable.

The Perfect Sheets

From the fitted and flat sheets to the pillowcases and duvet cover, this entire set is expertly balanced to keep you cool and comfortable for nights on end. See how Casper users are sleeping in the sheets reviews.

Casper Mattress with Sheets

Detail Oriented

While talking to people about sheets, we gained insights that went beyond the fabric itself. Our participants revealed common frustrations most people have with their bedding. So naturally, we wanted to solve for those as well.

  • My duvet gets bunched up and lost inside the cover.
    WE DESIGNED OUR DUVET COVER TO HAVE EASY-TO-ACCESS INTERIOR CORNER SNAPS TO KEEP YOUR DUVET SECURE.
  • I prefer sleeping without a top sheet.
    WE MADE OUR DUVET COVER OUT OF THE SAME COMFORTABLE MATERIAL AS OUR SHEETS, SO YOU DON’T NEED A TOP SHEET IF YOU DON’T WANT ONE.
  • I hate folding fitted sheets.
    WHO DOESN’T? THAT’S WHY WE ADDED SEAMS TO THE SIDES OF OUR FITTED SHEET, MAKING IT MUCH SIMPLER TO FOLD.
  • My fitted sheet is always popping off the bed.
    WE ADDED GRIPPY ELASTIC TO THE SEAMS TO KEEP IT IN PLACE, NO MATTER HOW MUCH YOU MOVE AROUND.
  • I always put my fitted sheet on the wrong way.
    WE PUT BLUE TABS ON THE TOP AND BOTTOM ENDS SO YOU’LL NEVER BE CONFUSED.
  • I’d rather not see my pillow.
