At the heart of every Sealy mattress is the support that's right for you and the Kelburn II Medium Hybrid king size mattress at RC Willey will provide the support you need to get a restful night's sleep. By precisely engineering the mattress into specific zones, a Sealy Posturpedic targets reinforced support, while providing exceptional full-body support. In every mattress they make, Sealy combines smart innovation, precise engineering and industry-leading testing to ensure quality and durability. You can trust Sealy to deliver durable support and comfort in every mattress.

The innovative hybrid mattresses pair the responsive support of an innerspring with the body-conforming comfort of memory foam. This unique hybrid design provides the best of both: lightly-conforming comfort on top, with stable deep down support below. It uses exclusive Posturepedic Technology™, with 20% more coils to deliver reinforced support where you need it most. The Hybrid line’s DuoChill™ Cooling Sleep System features twice the cool-to-the-touch technology – Sealy Chill™ Technology is integrated into the Chill™ Performance Tech Cover & Sealy Chill™ Immersion™ Advanced Memory Foam – this hybrid has the most cooling power in its class. Altogether, the Sealy Hybrid is the complete package, offering Sealy’s best in comfort, support and cooling technology.

Don't forget the mattress pad! When purchased at the same time as a mattress from RC Willey, our high-quality mattress pads help keep your mattress safe with a 10-year limited guarantee.
