The Four Seasons Sierra Plush mattress utilizes patented Phase Change technology sewn into the cover to cool the mattress quickly and keep you sleeping longer. In the Sierra Plush, Our Cool Gel Memory Foam is placed right under the cover to conform to your body, while regulating your body temperature. The soft High Resiliency Foam then provides you with proper pressure relief and durable support. The Support Core is High Density Foam using a Superior Edge Support, which provides a firmer seating edge to the mattress, increasing your overall sleeping surface.
