• Set Up: Simply take your mattress out of the box and enjoy watching it decompress. Jumping, walking, and sleeping on your mattress can speed up the process.

Casper is reimagining sleep from the ground up. All of Casper’s sleep products are developed in-house by our award-winning research and development team. The Casper Original Foam mattress is the perfect combination of support and cooling. Our ZonedSupportTM has three areas of targeted support for proper spinal alignment. Soft foam around the shoulders provide more relief to the upper body. Firmer foam under the hips, waist, and lower back help align your spine. Breathable open-cell foam layers allow airflow to soothe you to sleep. This premium foam is plush, yet resilient and conforms to your body to relieve pressure. The durable base foam prevents sinking and sagging and supports the whole body. It's designed to withstand years of use. The knit mattress covers have four way stretch, so you feel the full benefits of the below layers. Still unsure? Rest easy with our 100-night trial and free returns.
