Expert Review video placeholder
Expert Review by Jed
One of the top all-around mattresses for single sleepers in the Sealy collection, the Twin size Sealy Posturepedic Response Performance Cooper Mountain IV Plush Mattress features improvements across the board to the already great generation III model. With a Comfort Scale score of 6, the Cooper Mountain IV has a medium level of softness that is designed to provide an excellent combination of comfort and support.

Key features and improvements begin right in the quilt with the Comfort Loft Cover with MoistureProtect. This performance quilt is brilliantly designed to wick away moisture for a more comfortable night of sleep. A layer of Sealy Cushion Air Foam supplies initial body contouring, and it has a convoluted design that will help enhance airflow throughout the mattress. Back support is reinforced with the help of advanced Posturepedic Technology, more specifically the SealyCool Gel Memory Foam found in the center third. This not only provides better support, but also improved durability. A layer of Sealy Cushion Extra Soft Foam helps ensure deep down pressure relief to help decrease tossing and turning. Another bonus worth mentioning is that all the comfort materials used are CertiPUR-US certified. Back support is provided via the new and improved Sealy Response Pro Encased Coil System, an individually wrapped system that boasts a coil density of over 200 more coils than the generation III model. This system delivers excellent body contouring, provides deep down support, and helps isolate transfer of motion. This way, when movement occurs the other side remains undisrupted. The DuraFlex Edge, one of the best edge systems in the industry, keeps comfort and support consistent, even when resting to the edge. The model is completely adjustable base friendly.

To sum up, if you're searching for a great middle-of-the-road mattress in terms of both price and comfort, the Twin size Sealy Posturepedic Response Performance Cooper Mountain IV Plush Mattress is one of the best choices out there. The performance and comfort improvements from the generation III Cooper Mountain is one of the biggest jumps forward in many years.

Comfortable
We had been looking for a good mattress for awhile and chose to buy one at US Mattress again. We had a good experiemce with the US Mattress staff but the delivery service was difficult to to get scheduled. We are happy with the purchase but hope that US Mattress reconsideres who they use for delviery.

High quality mattress at a competitive price
We did a bit of local shopping before turning to US Mattress. They were great with their explanations and recommendations. We started with the Cushion Firm and slept on it 90 days. We ended up feeling that it was too firm, but we still like the support. We opted for the straight Plush instead of the plush pillowtop. It wasn't as dramatic a change as we expected (3 to a 6), but it is definitely an improvement. The price of the Plush even came down from the time of the original purchase. USM was very accomodating throughout. I think the next time I woud opt for the hybrid, but it's a whole lot more $$ and I'm not yet fully convinced about memory foam. If you want a bit softer on this mattress, I'd opt for the pillow top.
