The Four Seasons Coral Firm mattress utilizes patented Phase Change technology sewn into the cover to cool the mattress quickly and keep you sleeping longer. In the Coral, firm High Resiliency Foam is placed right under the cover to provide a firm conforming feel with proper pressure relief and durable support. Our Cool Gel Memory Foam then conforms to your body, while regulating your body temperature. 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.
