Feels soft, works hard.
Thick layers of breathable Boost® and React® foams cradle your every curve and create a plush feel without the "sink" you get from even top-of-the-line memory foam beds

Air flow-enhancing Boost-X® amplifies the conforming quality and resilience of the top layers—while also creating a smooth transition from the up-top softness into the high-density base that helps your mattress keep its shape without sagging over time.
The Climate Control
Our fills are all designed to keep you cool—and so are the fabrics we've engineered for the exterior. As Dri-Tec® wicks away moisture, Air-X® siding ventilates, regulating body heat for uninterrupted sleep.
