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

Key changes in the Cooper Mountain IV Cushion Firm start right in the quilt with the Comfort Loft Cover with MoistureProtect. This quilt consists of a performance enhancement that is expertly designed to draw moisture away from your body and keep you more comfortable. A layer of Sealy Cushion Air Foam supplies some initial body contouring, and it also helps promote a higher level of airflow throughout the mattress. The Cooper Mountain includes SealyCool Gel Memory Foam in the center third, and this achieves improved back support and prolonged durability. A layer of SealySupport Foam is incorporated to give the mattress a firmer underlying feel, and it works wonderfully along with the coil system to provide a solid, supportive feel. The Sealy Response Pro Encased Coil System consists of a series of barrel-shaped coils that ensure you receive the correct amount of support where it is most needed. Because each of the coils are individually encased, they can move independently for more targeted support and less motion transfer. This updated model has a density of over 200 more coils than the previous generation. This coil system is conveniently compatible with an adjustable base, and it boasts 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 improved durability, more usable sleeping space, and better edge support. The DuraFlex Edge makes it possible to sleep near the edges without feeling like you might roll off the side.

In conclusion, Sealy did a fantastic job upgrading a customer favorite from the generation III line and making it even better. If you like a firm comfort level and you want one of the top mattress values out there, the King size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is a great way to go.

I’m very pleased with my mattress set. The model name was different from the store I had seen it in. But I was able to find the one I wanted. Ordering and delivery was simple and easy. I was kept informed of the shipping movement. It arrived exactly when they said it would be there.

Looking for firm? This is a good mattress.
I was looking for a firm mattress, but after using a soft mattress for years, it has been a difficult change. I have had my new mattress for two weeks, and I still not get totally comfortable with it.

We are very satisfied with our new mattress rom U.S.Mattresses. It was made to perfection as specified and the price was much lower than other stores. We will buy from them again when the time arises and we will recommend them to our friends and family.
