The TEMPURHybrid Supreme is the first of three mattresses in this collection which combine advanced TEMPURmaterial for pressure point relief with new Precision micro coils, individually encapsulated in fabric pockets to provide exceptional support. Made from state-of the-art cold-drawn steel, each micro coil has a diameter of 45mm, is wound to seven turns and compressed to 10cm, an ideal stiffness to maximize response and comfort. This product is engineered to deliver a new, faster-responding feel by adapting to your temperature, weight and shape. If you share a bed, motion transfer is dampened because each person is independently supported so you can both sleep undisturbed. . .
