  • Experience the perfect balance of extra-firm support and deep pressure-relieving comfort. This luxury mattress features 3 exclusive technologies to balance comfort, support and temperature regulation:

    • Thermo°Cool yarn fabric cover with TENCEL® fibers, an exceptionally soft material designed to help improve heat and moisture flow at the sleep surface.
    • Cool Action Dual Effects® Gel Memory Foam helps provide more support where your body needs it and an enhanced ability to transport heat away from the mattress layers above it.
    • Pods gel-activated support layer works with our ComfortLast® Foam core to help provide extra support from the deepest parts of the mattress and a firmer seating edge.

    This mattress also features a layer of Serta® Support Foam underneath the Cool Action material, allowing you to experience its benefits from a firm mattress.



    Your iComfort® Sleep System mattress comes with a 10-year limited warranty.
