Sealy Hybrid™ Mattress

Our innovative Hybrid design provides the responsive support of an innerspring with the body-conforming comfort of memory foam. The center of the mattress is reinforced with 20% more of our densely packed system of coils for support where you need it most. Bringing you lightly-conforming comfort on top, with stable deep down support below.

Why You'll Love the Hybrid Line

Our exclusive Posturepedic Technology delivers reinforced support under the heaviest part of your body with 20% more coils—while also giving you that "sleep-on-top" feeling and comfort you expect from innerspring.
