Blending the best of advanced memory foam and traditional innerspring comfort creates a new category of comfort. This hybrid bed features a thick comfort layer of ventilated, gel-infused memory foam at the surface and a superior pocket-coil unit for excellent pressure relief and support. At the surface, three layers of foam create the conforming comfort of memory foam with design that enhances temperature-control and breathability. At its base, 12-gauge pocket coils offer the bounce and support of a traditional spring mattress. Mattress comes with a 10-year non-prorated warranty.
