The Sealy Posturepedic® Pro Spring Dupont II Firm Mattress pairs individually wrapped PrecisionFit™ Coils with SealyComfort™ Gel Foam comfort layers in a firm feel built for sleepers who want a supportive, minimal-sink surface. Reinforced support zones, a stable coil edge, and Sealy's 10-Year Limited Warranty back a mattress made in the USA.
Spring Support, Built Firm
The Dupont II Firm 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 Firm feel, the coil layer does more of the supporting work and the comfort layers stay thinner on top — less sink, more support, for sleepers who don't want a plush, contouring feel.
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.
Targeted Support
Engineered for All-Night Support
Every Sealy Posturepedic® mattress is engineered by Sealy's sleep team to keep you comfortably supported for the deep, relaxing sleep you need — night after night.
Sleep Position
Back & Stomach Sleepers
The Firm feel keeps sink to a minimum, so back and stomach sleepers stay supported and level instead of settling into a soft, contouring surface.
Targeted Support
Extra Support Where It's Needed
MaxSupport™ Technology reinforces the zones that carry the most weight, while PrecisionFit™ Coils flex head-to-toe to keep you comfortably supported all night.
