All-over elevation.
Layers of React ® and Boost-X ® breathable foams work together to create a firmer surface that keeps your body smoothly balanced from head to toe.

Our high-density foam base adds durable support under the cushioning top layers, helping air circulate while making sure your mattress keeps its shape without sagging or deflating 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.
