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.

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.

Great firmness. Does generate a awake at hips area.
Very good firmness. However, after about 40 days it does generate a slight swale where your hips and heavier part of torso lay. You cannot turn mattress over to counteract this, and if you flip ends you just created a more elongated swale. If you do try to roll to either side for sleeping, you get pressure on your rib cage because of the dip. Which could lead me to a 2.5 Stars in about a year of use.

Good Mattress
Good overall mattress for the price. I was expecting it to be firmer as it's rated 1.5 firmness, but it was actually a little bit softer than expected. However, it's still just barely firm enough for me.

Also, the sewings on the top of the mattress were not sewn in for 1/3 of the mattress. It's definitely an eye sore but probably doesn't affect usage of the mattress. Certainly seemed like mattress was made quickly with little quality control.
