Key Features of the Sealy Posturepedic Plus Determination II Ultra Firm Mattress:

• ComfortLoft Knit Cover with Chill & AllergenGuard – This cover features a medium loft, soft knit fabric made with durable spun yarns for a comfortable plush feeling next to your body. Additionally, Chill™ Technology provides cool-to-the-touch comfort designed for hot sleepers and AllergenGuard™ protects the mattress from common allergens like dust mites and dander, helping the mattress stay fresh.

• SealyCool Gel Memory Foam – This is a conforming foam with gel added for superior pressure point relief and deep-down cushioning support.

• Posturepedic Technology – Posturepedic Technology provides support where you need it most. At least 50% of your body weight sits in your back and hips so, Sealy has reinforced the center third of the mattress with a layer of SealyCool Gel Memory Foam to provide deep targeted support for exceptional all-over comfort.

• SealyCool Gel Foam Medium – This medium comfort conforming foam has gel added for superior pressure point relief and deep-down cushioning support.

• SealySupport Gel Foam Firm – This high-quality, firm comfort foam provides a plush supportive feel with contouring pressure relief.

• Response Pro HD Encased Coil System (Coil Density 1072) – The Response Pro HD Encased Coil System is comprised of hundreds of densely packed, individually encased hourglass-shape coils with a dual-stage design, meaning more coils are placed in the center third of the mattress to ensure you get proper support where you need it most. These individually encased coils allow each coil to move independently providing unique targeted support and reduced motion transfer so, motion on one side cannot be felt on the other side.

• SealySupport Foam – This is a high-quality support foam that is used in all Sealy Response Innerspring Mattresses. This foam gives a solid supportive feel and increases the durability of the mattress.

• DuraFlex Pro Edge System – A high-density, flexible coil border which surrounds the entire outer edge of the mattress improves durability, and provides an even surface to the very edge of the mattress. A perforated encasement design provides a more breathable edge. This system allows for more sleep space and ensures you won’t slip or roll out of bed.

• Adjustable Base Friendly

• 8 Vertical Handles

• 10-Year Limited Warranty – The Best warranty in the business.
