Offering a firm level of support with just a hint of cushioning, the iComfort Guidance mattress was designed to help restore and replenish your body as you sleep. This premium mattress utilizes EverFeel Triple Effects gel memory foam, which intelligently responds to your body in three ways: relieving pressure points, providing added support for ideal body alignment and regulating temperature as you sleep. Providing additional pressure point relief and support is a layer of Cool Action gel memory foam, infused with millions of MicroSupport beads which gather under the areas needing the most support while dissipating excess heat. Layers of Serta Support foam and Serta PillowSoft foam deliver additional body contouring support, while Serta's EverTemp technology helps the mattress to maintain a comfortable sleep temperature in any room environment. And finally, providing reinforced support to the mattress edges is the Serta Ultimate Edge Foam Support Core. 10 Year Warranty.
