Original 11-Inch Foam Mattress

Casper's in-house research and development team engineered this award-winning mattress designed with Zoned Support™ systems to help you sleep deeply and well. Softer under the shoulders and firmer under the hips, waist and lower back, the mattress promotes superb comfort and improved spinal alignment. Open-cell foams have tiny pores to let excess hot air escape so you can stay cool, and they work together with three additional foam layers (high-density memory foam, zoned transition foam and durable support foam) to enable a perfect night's rest.
