Expert Review video placeholder
Expert Review by Jed
From the quilt to the coil system, the Twin XL size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is a drastic improvement from the generation III model in every way. If you're searching for one of the best values in the Sealy line this year and prefer a firm Comfort Scale score of 3, this mattress may be the perfect choice for you.

Key updates in the Cooper Mountain IV Cushion Firm begin right in the quilt with the Comfort Loft Cover with MoistureProtect. This quilt contains performance enhancement that is designed to draw moisture away from your body throughout the night to keep you more comfortable. A layer of Sealy Cushion Air Foam supplies some initial body contouring, and it also helps promote increased airflow. The Cooper Mountain features SealyCool Gel Memory Foam in the center third that ensures better back support and prolonged durability. A layer of SealySupport Foam gives the mattress a firmer underlying feel, and it works well alongside the coil system to give you a more supportive, solid feel. The Sealy Response Pro Encased Coil System consists of several barrel-shaped coils that ensure you receive support where you need it. Each coil is encased, and this allows them to move independently for more targeted support and decreased motion transfer. Furthermore, the generation IV model has a density of over 200 more coils than the previous model. This coil system is conveniently adjustable base compatible, and it offers better contouring than tied coil systems. Also new to this year's line is the DuraFlex Edge, which is a flexible, high-density coil border that surrounds the mattress for better edge support, improved durability, and a more usable sleeping surface. This feature makes it possible to rest all the way at the edges and not feel like you're going to roll off the side.

To summarize, Sealy did an excellent job updating a customer favorite from the generation III line and making it even better. If you enjoy a firm feel and you're looking for one of the best mattress values available, the Twin XL size Sealy Posturepedic Response Performance Cooper Mountain IV Cushion Firm Mattress is a great way to go.

Sleeping tight in Erie!
We have found our dream bed! We sleep through the night and our Pug Titan has gone in our bedroom and slept in the bed all by himself during the day which he has never done since we have had him in the past 9 years. The chat representatives have been amazing utilize them!!
