Expert Review by Jed
If you like sleeping on a mattress that feels exceptionally dense, the Queen size Sealy Posturepedic Response Performance Cooper Mountain IV Firm Mattress is an excellent choice that is suitable for couples. With a rating of 1.5 on our Comfort Scale, it feels much like sleeping on a carpeted floor. If you like this sort of comfort, then you'll also appreciate the fact that the generation IV model features improvements to the quilt, foam quality, edge support, and coil count compared to the previous generation. In other words, the entire mattress has been greatly improved upon.

Starting at the top, one of the first noticeable upgrades is the Comfort Loft Cover with MoistureProtect. This premium quilt is soft to the touch, and it features a performance enhancement that is uniquely designed to draw moisture away from your body to help you stay cool while you sleep. Each of the comfort components are CertiPUR-US certified, including a layer of Sealy Cushion Air Foam that provides a bit of contouring and improved airflow. The Cooper Mountain IV contains Posturepedic Technology in the form of SealyCool Gel Memory Foam located in the center third, which is implemented to encourage prolonged durability and supply support to the lower back. For a dense and firm feel, a thick layer of Sealy Support Foam is also included. With an impressive coil density of over 200 more coils than the generation III model, this coil system feels super supportive. Furthermore, the individually wrapped system design results in better contouring than tied coil systems with minimized motion transfer to promote undisturbed sleep for couples. The DuraFlex Edge is one of the strongest edge systems available today. It not only makes it possible to sleep comfortably from edge to edge, but it feels very supportive at the same time.

In summary, the Queen size Sealy Posturepedic Response Performance Cooper Mountain IV Firm Mattress is an excellent choice if you prefer a firm comfort level. This model is very solid and firm, and it is designed to last over the next 10 years. The updates from the already great generation III model are certainly appreciated and welcome.

I am Dorothy's daugther, Brenda. I chose this mattress for my mom because I only buy Sealy Posturepedic mattresses. She needed something firm, but not a brick; therefore the Cooper Mountain III Firm Mattress will be a good choice for her.
Dorothy K on May 16, 2017
I called in and spoke with David. He was very helpful. He answered my questions and listened to my various shopping experiences. After we discussed several lines of mattresses and manufacturers, he suggested I go to Macy's to try the differend styles and models from the companies I was researching. I was able to get to a store and tried out the different beds. Glad I did. It really helped me make my decision. We will see how it goes from here but I expect it will be fine. Looking forward to it.

can the mattress be used on both sides?
A shopper on Feb 19, 2014
BEST ANSWER: This is a one sided mattress.
Does the mattress keep your body heat or is it cool?
A shopper on Aug 15, 2014
BEST ANSWER: Neither my husband nor I have noticed this mattress to hold heat. It is warm in our house in the summer, we live in georgia and keep the house around 78, but I do not believe it is any warmer on our bed than anywhere else in the house.
WILL THIS MATTRESS HOLD M 300 LB. FRAME??
jozeppie l on Apr 30, 2014
BEST ANSWER: Foam mattresses are better for people who are over 250 lbs because they are more resilient than typical innerspring units. Give us a call at 1-800-455-1052 and let our mattress experts help you pick the right mattress.
Is there a photo of the premium frame and low profile box spring?
Edwin N on Mar 19, 2014
BEST ANSWER: Hi Edwin, the low profile box spring looks exactly like the regular box spring in the product image. The only difference is that it is 5.25" thick instead of 9". Here is a link to a bed frame that looks exactly like the one you would receive: http://www.us-mattress.com/fashion-bed-group-universal-bed-frame.html
What are the measurements for your full mattress? my bed frame reuqires a mattress that is 74 inches long and 55 inches wide.

Good so far
This mattress is firm, but not extra-firm like I was expecting/hoping. However, even so, it's very comfortable and we like it a lot. Good support, and does very well on our platform bed.

Exactly As Expected.
After many, many months of comparing reviews, specs, etc (even with Costco) I purchased this bed and am very happy with it so far. The delivery was professional and I love my new bed that I've waited so long for. I almost purchased Costco's bed because of their services but found out that they actually have less coils and have their beds made to their specs to keep the price down. This bed has more coils and was very similar in price. And the delivery/removal price was even lower as well! Great Company! I took a risk and am glad I did. It is a firm bed with a little give on top. Not as hard as I thought it would be; which is good but hard enough. So far so good!

Firmness I've been dreaming of
Didn't realize how awful my prior mattress was until sleeping on this one. The support has eliminated that morning back stiffness. And sleeping on back or stomach is great.
