The Serta Isleworth Plush Mattress features Cool Twist Gel Memory Foam, an exclusive liquid gel-enhanced memory foam that helps move heat away from your body. This foam also gently conforms to your body, providing enhanced cushioning and helping reduce the pressure points that cause tossing and turning. The custom support system is constructed of foam and designed to provide proper support throughout the night, while also working to reduce pressure build-up that can disrupt a peaceful sleep. Serta’s StabL-Base Double Beam Foundation provides consistent support across the bottom of the mattress and lasting durability to the mattress sleep set.
Mattresses and foundations within the same brand have been tested together to comply with consumer flammability standards. If you have any questions concerning which mattress, box spring, or adjustable base to purchase, see a Mattress associate at your local Sears store.
