Expert Review by Jed
If you like sleeping on a mattress that feels exceptionally dense, the Twin size Sealy Posturepedic Response Performance Cooper Mountain IV Firm Mattress may be the perfect choice for you. With a Comfort Scale score of 1.5, its feel is akin to sleeping on a carpeted floor. If you prefer this type of comfort, then you'll also appreciate the fact that the generation IV model features upgrades to the coil count, edge support, foam quality, and quilt compared to the previous model. In other words, the entire mattress is far better.

Beginning at the top, one of the first improvements is the Comfort Loft Cover with MoistureProtect. This high quality quilt is soft to the touch and features a performance enhancement that is designed to draw moisture away from your body to keep you sleeping comfortably cool. The premium comfort layers 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 designed to promote durability and ensure support to the lower back. A thick layer of Sealy Support Foam achieves a very dense, firm feel. Back support is provided via the Sealy Response Pro Encased Coil System. With a coil density of over 200 more coils than the generation III model, this coil system feels incredibly supportive. Plus, the individually wrapped system design results in better contouring than tied coil systems with reduced motion transfer to promote undisturbed sleep. The DuraFlex Edge is one of the strongest edge systems on the market today and not only allows you to sleep edge to edge, but it also feels very supportive when doing so.

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

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.

Nice bed, not as firm as I was expecting. It moves a lot on my foundation, everyday I have to slide it back on straight.

Nice mattress wished it was as firm as specs indicated. A bit softer than expected.
Good mattress but from specs we thought it would be firmer.
