Sealy’s all-new Posturepedic Plus collection is an amazing upgrade to our most popular Sealy lineup. This is Sealy’s ultimate in an innerspring mattress, offering exceptional support from exclusive Posturepedic Technology that responds to your body’s unique needs. The Satisfied Plush Pillow Top starts with a ComfortLoft Knit cover with Chill technology and AllergenProtect which helps to protect from common allergens like dust mites. Below the cover, you’ll find Certipur-US certified SealyCool Air Gel Foam, SealyCool Gel Memory Foam, and a reinforced center third of SealyCool Gel Memory Foam to provide durable, breathable, conforming cushion and comfort. The all-new 1072 Response Pro HD Encased Coil System features a dual-stage design and provides targeted support while reducing motion transfer. The DuraFlex Pro Edge System is a high-density, flexible coil border surrounding the mattress for better edge support, more usable sleep surface and improved durability over a foam encased edge.
