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. Our Nova Foam mattress has the most luxurious plush feeling without sacrificing support or cooling. A velvety-soft layer makes bedtime feel extra cozy. The top layer has pillow-like fabrics that cradle your body and make you feel as if you were sinking into a cloud. Zoned SupportTM Pro has 7-areas of targeted support for healthy spinal alignment. Softer foam around the shoulders provide more relief to the upper body. Multiple ergonomic points provide pressure relief under shoulders, hips, waist and lower back. More support where you need it, with the plushness you crave. AirScapeTM 2 means there are two layers of perforated breathable foam to help reduce heat. Tiny holes move hot air and body heat away, creating air channels that allow heat to escape. These small perforations eliminate the risk of overheating during the night. The durable base foam prevents sinking and sagging and supports the whole body. The cover is made with recycled materials and easily zips off. 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.
