The Twin XL size Sealy Posturepedic Response Premium Warrenville IV Plush Pillow Top Mattress is an excellent choice if you're in the lookout for a mattress that shares a lot in common with the top of the line version, but at a more affordable price point. This mattress has a medium soft comfort level that is designed to provide a great combination of contouring and support. This is the fourth generation of the Warrenville mattress, and it features a number of great improvements from the generation III line, including the coil system, quilt, foam quality, and edge support.

Essential components in the Sealy Posturepedic Response Premium Warrenville IV Plush Pillow Top Mattress start right on top with the SupremeLoft Cover with MoistureProtect and AllergenProtect Technology. This high quality quilt is designed to provide a healthier sleep environment, protect against allergens, and wick away moisture. The comfort foams are now all CertiPUR-US certified to meet or exceed the highest quality standards in bedding. The Sealy Cushion Air Ultra Soft Foam promotes good airflow, supplies initial conforming, and offers a softer feel. A layer of SealyCushion Extra Soft Foam delivers deep down pressure relief to help prevent tossing and turning. Another layer of SealyCushion Extra Soft Foam further enhances this feeling and helps encourage good spinal alignment, which is particularly beneficial for side sleepers. The Warrenville IV utilizes Posturepedic Technology located in the center third of the mattress to enhance support to the lower back and improve durability. This is achieved through the SealyCool Gel Memory Foam Center in addition to targeted support to that area from the coil system. Speaking of the coil system, the Sealy Response Pro HD Encased Coil System provides targeted support by using individually wrapped coils that conform independently to the curves of your body. This system is conveniently adjustable base compatible, and it helps isolate motion when movement occurs so the other side remains undisrupted. Also newly added to this model is the DuraFlex Edge, which is one of the best edge systems available today. It creates a consistent feel, even when you are resting at the edge, as well as a sturdy area to sit.

To summarize, the Twin XL size Sealy Posturepedic Response Premium Warrenville IV Plush Pillow Top Mattress is a great mattress in the upper-end category. The many improvements Sealy has made to the previous line have made this model one of the best available at this price point. It's made to last, and it comes backed by a 10-year warranty.
