Guaranteed To Keep You Cool

Temperature-regulating memory foam and a breathable layer of independent coils maximize air flow to keep you feeling cool all night long.

The mix of the memory foam and springs affords a lighter mattress, feel of less density, and cooler sleeping experience. This mattress is simply better because of the feel of memory foam without the feel of density and associated heat that seems captured in a full foam mattress.”– Mark W (Washington, DC)
