Expert Review by Jed
If you're a side sleeper who needs great pressure relief or simply someone who likes a soft yet supportive feel, the Twin XL size Sealy Posturepedic Response Performance Cooper Mountain IV Plush Pillow Top Mattress is a fantastic option. The previous model was one of the most popular mattresses not only from Sealy but on our site in general, and the new version boasts numerous upgrades across the board. With a score of 7 on our Comfort Scale, this model supplies a soft initial feel with firm underlying support.

Noteworthy improvements to the Cooper Mountain include the Comfort Loft Cover with MoistureProtect, a quilt designed to wick away moisture for a more comfortable and cool night of sleep. Comfort is primarily provided through premium polyurethane foams, which are all CertiPUR-US Certified. A layer of Sealy Air Foam offers initial body contouring, and it is expertly designed to promote increased airflow. A layer of SealyCushion Extra Soft Foam helps soothe pressure points to prevent tossing and turning and encourage better blood circulation. The SealyCool Gel Memory Foam layer found in the center third offers more support to the lower back, and it also makes the mattress more durable. An additional layer of SealyCushion Extra Soft Foam ensures deep down pressure relief, and it is built to really help side sleepers get the contouring that is necessary to avoid waking up with achy limbs. Support is provided with the help of the Sealy Response Pro Encased Coil System, a coil system that includes a coil density of over 200 more coils than the previous version. This coil system is among the most forgiving on the market, and it contours well to your body's curves while ensuring deep down support. It's particularly helpful for those who expect a pet to jump into bed because when movement occurs on one side very little motion is felt on the other. It's also conveniently adjustable base compatible. One of the best edge systems on the market today, the DuraFlex Edge also represents an improvement in edge support technology. It allows you to sleep anywhere on the surface without sacrificing support or comfort.

In summary, if you prefer a soft feel this is one of the top choices available on our site. The attention to detail Sealy gave to this mattress is incredible and leaves nothing to be desired at this price point. This mattress is even backed by a 10-year warranty to ensure your satisfaction.

Good night’s sleep!
Mattress was just as described. More soft than firm. Good quality. I’d recommend this mattress as it was a good middle of the road price and quality.

The bed is too soft and does not seem to have the best quality. Definitely will exchange for another mattress.
