Experience 15x better cooling power throughout the night with Serta’s Arctic Plush Memory Foam Mattress. Designed and built in the USA, this soft cooling mattress for hot sleepers features the exclusive, three-part Reactex® System to pull heat away from your body and down into the mattress for consistently cool relief. Conforming to your body’s curves, CustomFit™ high-density memory foam offers comfortable support, while two layers of gel-infused foam increase airflow with substantial pressure-relieving ease. The new and improved Serta® foam core creates uniform edge-to-edge support for any sleep position.
