CoreSupport Center

Sealy Posturepedic is the only mattress that features the CoreSupport Center.

The center third of the mattress (the area that gets the most use) is powerpacked to:

  • enhance support
  • resist body impressions

so your mattress feels as good after ten years as it did the day you brought it home.

Titanium DSx Innerspring

The resilience of the CoreSupport Center is enhanced by the strength of the Titanium DSx innerspring that lies just beneath it (Titanium is twice as strong as steel)

It's on the innerspring that gives you dual-stage support; conforming support on the surface and deep-down support underneath.

And each coil is twice-tempered to maintain maximum support over the life of your mattress.

LiftRight Surround Handles

Sealy has considered all of the ways you interact with your bed and we've made it easier for you. Whether you're changing your sheets, repositioning your mattress or moving your bed, you'll find our LiftRight Surround Handles right where you need them when you need them.

StayTight Foundation

And Sealy Posturepedic is the only mattress that features the StayTight Foundation with a rubberized gripper fabric that holds your mattress in place, and keeps your sheets and bed skirt right where they belong.
