The Sealy Posturepedic Keyes Medium Mattress in full size (53" x 74.5") is an 11.5-inch performance innerspring mattress designed for balanced comfort and support. It features Response Pro Encased Coils with a reinforced center third that delivers targeted support to the heaviest part of the body, helping maintain natural spinal alignment throughout the night.

The mattress incorporates SealyCool Gel Memory Foam for pressure relief and temperature regulation, along with a DuraFlex Coil Edge system that provides a high-density, flexible coil border for better edge support, more usable sleeping surface, and improved durability. The SupremeLoft antibacterial cover wicks away moisture for a cool, refreshing feel while keeping the mattress protected.

This medium-feel mattress is ideal for sleepers who want a balance between firm and plush, and is particularly well-suited for side and stomach sleepers. It is sold as a mattress only without a box spring or foundation. Backed by a Sealy 10-year limited warranty. Designed, assembled, and tested in the USA.
