Our goal was to balance the right amount of comfort, support, quality and firmness into one ideal mattress.

Comfort	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.	The ventilated viscoelastic hybrid foam is anti-microbial and prevents any moisture from accumulating. The top layer allows air to circulate, keeping you cool while adapting to your body. It identifies the pressure points, reduces the temperature and the firmness of these points in seconds only.
Support	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.	An element that makes this mattress truly unique is the proprietary support frame. This keeps the mattress from flattening out when you sit along any of the edges and helps to reinforce the structure. The support layer serves as a transition between the top layer and the base. It is designed for your comfort and provides full body support to ensure a better sleep. The first layer, or base, of the ultimate mattress is built with high-density foam and acts as a boxspring, while providing unparalleled reinforcement. It adds durability, strength and comfort without feeling too firm.
