The Serta iSeries® mattress is built to feel like a traditional mattress while offering the benefits of gel memory foam technology. It features a layer of our Cool Action™ Dual Effects® Gel Memory Foam for enhanced cooling, comforting, and targeted support. Plus, a layer of Serta® PillowSoft™ Foam gently contours to the body for enhanced cushioning.  Below the luxurious foam layers is the Duet® Coil Individually Wrapped Coil-in-Coil Support System with BestEdge® Foam Encasement for deep support and to maximize your sleep surface.
