Expert Review by Jed
One of the best all-around mattresses for couples in the Sealy collection, the King size Sealy Posturepedic Response Performance Cooper Mountain IV Plush Mattress features updates across the board to the already wonderful generation III model. Scoring a rating of 6 on our Comfort Scale, this mattress has a medium level of softness that is designed to give you an excellent combination of support and comfort.

Noteworthy components and improvements begin right in the quilt with the Comfort Loft Cover with MoistureProtect. This performance quilt is uniquely built to wick away moisture for a comfortably cool night of sleep. A layer of Sealy Cushion Air Foam provides some initial body contouring, and it has a convoluted design that promotes increased airflow throughout the mattress. Essential back support is reinforced with the help of Posturepedic Technology, more specifically the SealyCool Gel Memory Foam included in the center third. This premium material not only ensures improved support, but also better durability. A layer of Sealy Cushion Extra Soft Foam provides deep down pressure relief in order to prevent you from tossing and turning. Another benefit worth mentioning is that each of the comfort materials used in this mattress are CertiPUR-US certified. Crucial back support is provided with the help of the newly improved Sealy Response Pro Encased Coil System, an individually wrapped system that has a coil density of over 200 more coils than the previous generation. This expertly engineered system provides close body contouring, delivers deep down support, and helps isolate motion transfer. This way, when movement takes place the sleeper on the other side keeps resting soundly. The DuraFlex Edge, which is one of the top edge systems, ensures that comfort and support are consistent across the surface, even at the edges. The mattress is conveniently adjustable base friendly.

In conclusion, if you want a great middle-of-the-road mattress in terms of both price and comfort, the King size Sealy Posturepedic Response Performance Cooper Mountain IV Plush Mattress is one of the best choices available.
