Expert Review by Jed
If you like resting on a mattress that feels really dense, the Twin XL size Sealy Posturepedic Response Performance Cooper Mountain IV Firm Mattress may be the ideal choice for you. With a Comfort Scale rating of 1.5, its feel is similar to sleeping on a carpeted floor. If you enjoy this kind of comfort, then you'll also appreciate the fact that the generation IV model features upgrades to the coil count, quilt, edge support, and foam quality compared to the previous model. In other words, the entire mattress has been improved.

Beginning at the top, one of the first updates is the Comfort Loft Cover with MoistureProtect. This high grade quilt is soft to the touch and features a performance enhancement that is specially designed to draw moisture away from your body to ensure you sleep comfortably cool. The various comfort components are all CertiPUR-US certified and include a layer of Sealy Cushion Air Foam for a bit of contouring and improved airflow. The Cooper Mountain IV contains Posturepedic Technology in the form of SealyCool Gel Memory Foam found in the center third, which is engineered to promote durability and provide ample support to the lower back. A thick layer of Sealy Support Foam helps the mattress achieve a very firm, dense feel. Essential back support is delivered via the Sealy Response Pro Encased Coil System. With a coil density of over 200 more coils than the generation III version, this coil system feels exceptionally supportive. Plus, the individually wrapped system design results in better contouring than tied coil systems with decreased motion transfer to promote undisturbed sleep. The DuraFlex Edge is one of the strongest edge systems on the market today and not only makes it possible to sleep comfortably from edge to edge, but it also feels very supportive while doing so.

In conclusion, the Twin XL size Sealy Posturepedic Response Performance Cooper Mountain IV Firm Mattress is a wonderful choice if you prefer a firm feel. This mattress feels incredibly firm and solid, and it is built to last over the next 10 years. The updates from the already good generation III model are most welcome and appreciated.

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.
