Expert Review by Jed
From the quilt to the coil system, the Twin size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is a big improvement from the generation III model in every way. If you're on the lookout for one of the best values in the Sealy line this year and want a firm Comfort Scale score of 3, this mattress may be perfect for you.

Key improvements in the Cooper Mountain IV Cushion Firm begin right in the quilt with the Comfort Loft Cover with MoistureProtect. This quilt contains performance enhancement that is designed to draw moisture away from your body throughout the night and help keep you more comfortable. A layer of Sealy Cushion Air Foam offers initial body contouring and even promotes better airflow. The Cooper Mountain features SealyCool Gel Memory Foam in the center third that helps provide better back support and prolonged durability. A layer of SealySupport Foam creates a firmer underlying feel and works well along with the coil system to give you a more solid, supportive feel. The Sealy Response Pro Encased Coil System utilizes barrel-shaped coils to ensure you receive support where you need it. Each coil is encased to allow it to move independently for more targeted support and reduced motion transfer. Also, the generation IV model has a density of over 200 more coils than the previous model. This coil system is adjustable base compatible, 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 better edge support, more usable sleeping surface, and improved durability. This feature makes it possible to sleep all the way to the edge and not feel like you're going to roll off the side.

To sum up, Sealy did an excellent job upgrading a customer favorite from the generation III line and making it even better. If you prefer a firm feel and you're searching for one of the best mattress values available, the Twin size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is a great way to go.

Quality Firm Mattress for a Great Price
I have been very happy with this mattress. I sleep on my stomach so I need something firm but still comfortable (i.e. not a rock). My back has been very happy on this mattress. Also, I initially found this at my local mattress store and when I searched online the price was about $200 lower on US Mattress. I learned from the mattress store to look for a firm mattress with tight quilt lines on the top, and that will indicate firmness. This is a quality mattress for a great price.

Best bed
Bed is very comfortable and on the firm side. My puppy approves. Best bed I have had in a long time. I have tried the memory foam beds and this is by far the best. I would not recommend a memory foam at all.
