From the quilt to the coil system, the Full size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is a great improvement from the generation III model in every way possible. If you want one of the best values in the Sealy line this year and you prefer a firm Comfort Scale rating of 3, this model may be the perfect choice for you.

Notable upgrades in the Cooper Mountain IV Cushion Firm begin right in the quilt with the Comfort Loft Cover with MoistureProtect. This quilt utilizes performance enhancement that is designed to draw moisture away from your body to keep you more comfortable. A layer of Sealy Cushion Air Foam delivers some initial body contouring, and it also increases the airflow throughout the mattress. The Cooper Mountain features SealyCool Gel Memory Foam in the center third, and this provides better back support and prolonged durability. A layer of SealySupport Foam helps the mattress achieve a firmer underlying feel, and it works well alongside the coil system to give you a feeling that is more solid and supportive. The Sealy Response Pro Encased Coil System uses a series of barrel-shaped coils to ensure you receive support where you need it. Each coil is individually encased, and this allows the coils to move independently for more targeted support and minimal motion transfer. Furthermore, the generation IV model has a density of over 200 more coils than the previous version. This coil system is conveniently adjustable base friendly, and it offers better contouring than tied coil systems. Also new to this year's line is the DuraFlex Edge, which is a flexible, high-density coil border that surrounds the mattress for more usable sleeping surface, better edge support, and improved durability. This addition makes it possible to rest all the way at the edges without feeling like you're going to roll off the side.

In summary, Sealy did an excellent job upgrading a customer favorite from the generation III line and making it even better. If you enjoy a firm feel and you're looking for one of the best mattress values out there, the Full size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is a great way to go.
