The MOLECULE Hybrid 13" Cooling Memory Mattress features the best of both worlds with temperature regulating memory foam and the MOLECULEedge coil system of steel precision springs to provide adaptive, support for a responsive sleep surface. The coils respond and actively contour to your body, lifting you where you need it and allowing heavier areas to sink, keeping you in perfect alignment all night long. Each coil is individually encased and zoned for customized, targeted comfort while reducing motion transfer between sleeping partners. The MOLECULEedge coil system has open-air channels around the coils to keep the air flowing and heat away from the body. Smaller, targeted coils along the sides provide advanced edge-to-edge support, eliminating that roll-off feeling and improving durability. The luxurious extra plush quilted cover features Microban antimicrobial protection treatment to inhibit the growth of bacteria for long-lasting freshness and a cleaner sleep. Our engineers developed our proprietary advanced foams, AirTEC, and MolecularFLO for heat dissipation, cooling comfort, and maximum support. The RecoveryFLO 5-zone support layer is designed to support you exactly where you need it. It offers hyper-targeted, self-adjusting support for different parts of the body for advanced spine alignment.
