The luxuriously plush Prodigy III mattress is the perfect choice for anyone who enjoys cloud soft, gentle support. Featuring thick layers of EverCool Plus and PillowSoft memory foams, this mattress contours to every curve while dissipating body heat for a cool, comfortable feel. Adding to the sinkability factor is Cool Action gel memory foam, targeting the areas of your body that need the most support with millions of gel beads, relieving pressure points exactly where you need it. A thick layer of EverFeel Triple Effects gel memory foam intelligently responds to your body in three ways: relieving pressure points, providing added support for ideal body alignment and regulating temperature as you sleep. Serta's EverTemp technology helps each layer of gel memory foam maintain a comfortable sleep temperature in any room environment. The Serta Ultimate Edge Foam Support Core reinforces the mattress perimeter, allowing you to stay supported to the mattress edge. 10 Year Warranty.
