The Sealy Posturepedic TrueForm™ is the first mattress to combine the pressure-relieving characteristics of memory foam with our Posturepedic support. This mattress is distinctive for its cradling feel, and it’s designed to eliminate uncomfortable pressure points that cause tossing and turning. Plus our exclusive Outlast® Smart Fabric provides a consistent temperature for your body throughout the night; not too hot, not too cool.
