An extra cushioned sleep surface and a cool feel are what Serta delivers with its Classic 11.5" Plush Eurotop Mattress. Cool Twist Gel is swirled directly into a breathable foam that promotes airflow and heat dissipation which are both conducive to a deeper sleep. Individually wrapped coils in concert with Pillow Soft Aire foam provide contouring and cradling support along with enhanced cushioning so you can feel total comfort throughout the night.
