Product Description

Meet the high-performance mattress designed for people who live an active life and still want deep, uninterrupted rest. 

The Core Znergy™ Sleep System layers cooling gel quilt foam and copper-infused memory foam over a responsive nano-coil comfort layer, all supported by a 3-zone wrapped-coil core. 

The result is a firmly balanced feel that keeps back and stomach sleepers aligned yet cushioned, while the copper-zinc Znergy fabric works around the clock to fight odor and wick away excess heat. 

Edge-to-edge reinforcement lets you stretch out without that “roll-off” sensation, and every layer is engineered to breathe so you stay comfortably dry. All night, every night. 

Pair it with any solid foundation or adjustable base, unbox, and enjoy the 120-night comfort guarantee backed by a 10-year warranty.
