Expert Review video placeholder
Expert Review by Jed
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.

I love my new copper mountain IV mattress. It fits perfectly to your body and so comfortable. And I can not feel when my husband moves or gets up through the night. It is awesome. Thank-you so much.

We are very happy with our mattress
We were hopeful that we would like our mattress but we are very very happy with it and highly recommend it. Plus US Mattress was great with both helpful information and service

We love these mattresses
We have purchased 3 mattresses for our family and we are thrilled with them. They are very comfortable and the prices at US Mattress are the best

It's been 3 weeks since our mattress arrived
We are back to getting a great nights sleep again. I was leery at first that our mattress would be too firm, but, after the 1st week both of us were waking up refreshed. This mattress is giving us the back support we needed. Your online video reviews helped with decision making. Ordering was a breeze and your communications and delivery is a well oiled machine. Great experience.

Excellent Mattress
Did my research on mattresses - love this one especially for the price (on sale). Several years back I had purchased the same one, but it was less firm. I now what a firm mattress (and put a memory foam topper on it), this mattress is firm. Also like it has handles on the side, many mattresses dont have that anymore. Delivery was excellent, phone call to schedule & confirm and on time delivery.

Great mattress for back pain
Great mattress, not too soft and not too firm. It was for my parents, and my dad was able to sleep all night in it happily, when he had been having to sleep in a recliner due to back pain with his old mattress. It’s supportive enough for a 6’5”, 267 lb man.

I love this bed! Delivery was prompt and they removed my old set. This bed is just the right firmness but still feels like a luxury pillow top.

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.
