Posturepedic® - Support Where You Need It Most

  • Sealy’s exclusive technique reinforces the centre third of the mattress to provide extra support for your back and core.
  • Only Sealy® has Posturepedic® support for your back and core. It’s targeted to the individual areas of your body that need it most so your body stays level while you sleep.
  • Built to deliver middle-of-the-mattress support and pressure relief—for truly best-of-the-best sleep.
  • Targeted Support, where you need it. Developed with orthopedic specialists in the 50s, Posturepedic® provides reinforced support for your back and core, where you need it most.
