When shopping for a Split-King Size mattress just remember, "There is no one alive who is you-er than you." (Dr. Seuss) This is important to remember when selecting a mattress.  At the heart of every Sealy mattress is the support that's right for you. Sealy innerspring mattresses offer exceptional full-body support with ease of movement for that sleep-on-top feeling and comfort you want. The Heartwarming Cushion Firm is part of our Sealy Response line from the Sealy Performance collection. This collection offers durable all-over support plus exclusive Posturepedic technology for reinforced support where you need it most for a truly comfortable night's sleep.

Essential Split-King Size mattress features in the Sealy Posturepedic Response Performance Heartwarming Cushion Firm Mattress include comfort foams that are 100% CertiPUR-US certified to meet or exceed the highest quality standards in bedding. The top layer of Sealy Cushion Air Foam closely contours to the body and promotes good airflow throughout the mattress. The Posturepedic Technology layer utilizes Sealy Cool Gel Memory Foam in the center third to provide more support to the lower back and enhance durability. A layer of Sealy Cushion Extra Soft Foam delivers deep down pressure relief to help prevent tossing and turning. Also, a layer of Sealy Support Firm Foam acts as a foundational foam to give the mattress a supportive, firm underlying feel. Back support is provided with the help of the Sealy Response Coil System, which uses hundreds of traditionally tied coils provide solid support. If you tend to sleep at the edges of the mattress, the Solid Edge HD Foam Encasement is a welcomed feature since it helps prevent roll off and promotes good comfort.

The Sealy Posturepedic Response Performance Heartwarming Cushion Firm Mattress combines good quality comfort materials with a capable coil system to result in a good overall value. Dependably made, this mattress comes backed by a 10-year warranty.
