We added an extra layer of Serta Gel Memory Foam which provides cradling comfort and allows airflow to keep you cool. PillowSoft Foam is an extra soft foam that gently contours the body to enhanced cushioning support. We also our CoolTwist Gel Foam where cooling gel is swirled directly into a breathable foam designed to promote airflow and heat dissipation.The 805 Individually Wrapped Coil System provides contouring, cradling support. This coil system also features Serta’s BestEdge Foam Encasement technology –an extra-deep foam rail to help reduce edge roll-off and extend the sleep surface.
