Offers multiple price points. The open cell design of the Gel Foam allows air and moisture movement resulting in a cooler night's sleep. Gel Foam also has improved pressure relief and support for the recessed parts of the body and superior weight distribution along with superior durability. The cool gel is whorled into memory foam during production, allowing the gel to be completely bonded to foam and providing consistent gel coverage. All models feature the Gel Foam as the top layer to maximize its benefits.
