Casper Sleep Original Foam King Size Mattress - Medium Firm Memory Foam Bed

Casper is reimagining sleep from the ground up. The Casper Original Foam mattress is the perfect combination of support and cooling, developed in-house by our award-winning research and development team. Our ZonedSupportTM has three areas of targeted support for proper spinal alignment, with soft foam around the shoulders providing more relief to the upper body, and firmer foam under the hips, waist, and lower back helping to align your spine. Breathable open-cell foam layers allow airflow to soothe you to sleep, and the premium foam is plush yet resilient, conforming to your body to relieve pressure. The durable base foam prevents sinking and sagging, supporting the whole body and designed to withstand years of use. The knit mattress covers have four-way stretch, allowing you to feel the full benefits of the layers beneath.

Still unsure? Rest easy with our 100-night trial and free returns. Setting up is simple - just take your mattress out of the box and enjoy watching it decompress. Jumping, walking, and sleeping on your mattress can speed up the process. All of Casper's sleep products are developed in-house by our award-winning research and development team, ensuring the highest quality and innovation in sleep technology.
