TEMPUR-Flex Supreme Breeze Mattress, California King

A - Cooling Cover Performance fabric cover that's lightweight, breathable and infused with innovative cooling technology to help create a cooler sleeping surface. B - Comfort Layer Extra-soft TEMPUR-ES® material is infused with PureCool™ for cooling comfort, determining the mattress feel and level of TEMPUR-Adapt™ and drawing excess heat away from the body. C - Response Layer Made up of quick-responding TEMPUR-Response™ material (which delivers a more familiar, slightly springy feel), it quickly provides the responsive support your body needs and helps distribute body weight evenly across the mattress. D - Dynamic Support Layer Made up of innovative, densely-placed precision coils, it works in harmony with the Response Layer to actively react to your body's movement. E - Base Layer This layer serves as the "base" for the TEMPUR® material above it, and is also designed to help disperse heat from the mattress.
