Expert Review by Jed
From the quilt to the coil system, the Queen size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is an excellent improvement from the generation III model in every possible way. If you are after one of the best values in the Sealy line this year and you prefer a firm score of 3 on our Comfort Scale, this may be the perfect choice for you.

Noteworthy updates in the Cooper Mountain IV Cushion Firm begin right in the quilt with the Comfort Loft Cover with MoistureProtect. This quilt contains a performance enhancement that is specially designed to draw moisture away from your body to keep you more comfortable. A layer of Sealy Cushion Air Foam gives you some initial body contouring, and it also helps increase the airflow throughout the mattress. The Cooper Mountain features SealyCool Gel Memory Foam in the center third, and this results in better back support and prolonged durability. A layer of SealySupport Foam helps the mattress achieve a firmer underlying feel, and it works well in conjunction with the coil system to give you a feeling that is more supportive and solid. The Sealy Response Pro Encased Coil System utilizes a series of barrel-shaped coils to ensure you receive the right amount of support where you need it the most. Since each coil is individually encased, the coils can move independently for more targeted support and reduced motion transfer. The new model has an impressive density of over 200 more coils than the previous version. This coil system is conveniently adjustable base compatible, 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, improved durability, and better edge support. This new feature makes it possible to sleep near the edges without feeling like you might roll off the side.

To conclude, Sealy did a super job upgrading a customer favorite from the generation III line and making it even better. If you like a firm feel and you want one of the best mattress values out there, the Queen size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is a great way to go.
