Comfort
Our high-quality memory foam adapts to your body size, shape and sleep position to ensure a great sleep no matter which feel is right for you.
Cooling helps keep you at the right temperature for your best rest. We also own the manufacturing process, so we can guarantee all Casper mattresses meet our high standards for comfort. Plus every mattress saves up to 9 recycled bottles from the environment. A top layer of proprietary perforated breathable foam helps reduce heat, the tiny holes move hot air and body heat away. This innovative cooling system is designed to help keep you cool all night.
Support
Choose our soft layer for a cozier, more "in-the-bed" feel. Choose our firm layer for a sturdier, "on-the-bed" feel. Engineered to be highly durable and resilient. We’ve tested it, and we know it bounces back every time.
The durable base is engineered to prevent sinking and sagging while supporting your whole body. Premium AirScape™ foam conforms to your body to relieve pressure.
