Casper's award-winning design shines in the brand's signature Casper mattress. Light and breathable, its open cell foam allows for cool air flow throughout your night's sleep. Additional layers of pressure-relieving foam absorb the weight of your body, transferring tension away from key pressure points so you can sleep comfortably. For extra pressure relief, Casper's trademarked Zoned Support provides different levels of firmness beneath your shoulders and hips to obtain optimal spinal alignment. Designed for all body types, this mattress offers the support you need whether you sleep on your back, side or stomach. 10 Year Limited Warranty
