Expert Review by Jed
If you want a mattress that feels exceptionally dense, the King size Sealy Posturepedic Response Performance Cooper Mountain IV Firm Mattress is a great choice that is plenty large enough for couples. With a score of 1.5 on our Comfort Scale, it feels a lot like sleeping on a carpeted floor. If you like this style of comfort, then you'll also appreciate the fact that the generation IV model features improvements to the quilt, coil count, foam quality, and edge support in comparison to the last generation. In other words, the entire design has been greatly improved upon.

Beginning at the top, one of the first noteworthy updates is the Comfort Loft Cover with MoistureProtect. This premium quilt is soft to the touch, and it utilizes a performance enhancement that is expertly designed to draw moisture away from your body to help you sleep comfortably cool. Each of the comfort components are CertiPUR-US certified, including a layer of Sealy Cushion Air Foam that offers a bit of contouring and promotes airflow throughout the mattress. The Cooper Mountain IV includes Posturepedic Technology in the form of SealyCool Gel Memory Foam in the center third, which is incorporated to encourage prolonged durability and supply support to the crucial lower back area. For a firm and dense feel, a thick layer of Sealy Support Foam is also added. With an impressive coil density of over 200 more coils than the generation III version, this coil system is exceptionally supportive. Furthermore, the individually wrapped system design achieves better contouring than tied coil systems with minimized motion transfer to promote undisrupted sleep for couples. The DuraFlex Edge is one of the strongest edge systems on the market today. It not only makes it possible to rest comfortably from edge to edge, but it feels incredibly supportive at the same time.

To sum up, the King size Sealy Posturepedic Response Performance Cooper Mountain IV Firm Mattress is a superb choice if you prefer a firm comfort level. This mattress is incredibly solid and firm, and it is made to withstand use over the next 10 years. The improvements from the already great generation III model are definitely appreciated and welcome.

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.
