Expert Review by Jed
If you are looking for a large mattress that feels incredibly dense, the California King size Sealy Posturepedic Response Performance Cooper Mountain IV Firm Mattress is an excellent choice. Scoring a rating of 1.5 on our Comfort Scale, it feels much like sleeping on a carpeted floor. If this kind of comfort is appealing to you, then you are also sure to appreciate the fact that the generation IV model features updates to the quilt, foam quality, edge support, and coil count in comparison to the last version. In other words, the entire design has been significantly improved.

Starting at the top, one of the first notable upgrades is the Comfort Loft Cover with MoistureProtect. This high quality quilt is soft to the touch, and it incorporates a performance enhancement that is expertly engineered to draw moisture away from your body to help you sleep comfortably cool all night. All of the comfort components are CertiPUR-US certified, including a layer of Sealy Cushion Air Foam that offers a bit of contouring and increases the airflow throughout the mattress. The Cooper Mountain IV utilizes Posturepedic Technology in the form of SealyCool Gel Memory Foam in the center third, which is added to encourage prolonged durability and supply support to the important lower back area. For a firm and dense feel, a thick layer of Sealy Support Foam is also built into the mattress. With a coil density of over a whopping 200 more coils than the generation III model, this coil system is super supportive. In addition, the individually wrapped design of the coil system is able to achieve far better contouring than tied coil systems as well as minimized transfer of motion. The DuraFlex Edge is one of the strongest edge systems that you can find. It not only makes it possible to rest comfortably across the entire surface, but it feels supportive at the same time.

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

Love it
We really like the mattress. Me and my husband had light back problems in the past and we always prefer a firmer mattress. Before buying this one, we went to a mattress store to try different levels of firmness and it's very apparent that it's only the extra firm mattresses that can give me enough back support that I felt completely comfortable in. This mattress gives me such kind of support and it's also very comfortable. We love it.

Softer than I thought
Given a scale of 1.5, I thought this mattress would be firm enough. But out of my expectation, this mattress is still soft and it leaves my body print after I used for only 2 weeks.
