The Sealy Posturepedic® Pro Spring Dupont II Medium Mattress pairs individually wrapped PrecisionFit™ Coils with SealyComfort™ Gel Foam comfort layers in a balanced medium feel built for sleepers who want cushioning without losing support. Reinforced support zones, a stable coil edge, and Sealy's 10-Year Limited Warranty back a mattress made in the USA.
Spring Support, Balanced Just Right
The Dupont II Medium is part of Sealy's Posturepedic® Pro Spring line: an all-innerspring construction with individually wrapped coils topped by gel foam comfort layers. In the Medium feel, the comfort layers and coil layer are balanced evenly, so you get noticeable cushioning at the shoulders and hips without sacrificing the supportive lift of the coils.
It's built with Sealy's PrecisionFit™ Coils, SealyComfort™ Gel Foam, SealySupport™ Gel Foam, MaxSupport™ Technology, and a DuraFlex™ Coil Edge for a stable perimeter.
