The Plank Firm Luxe is a flippable hybrid mattress with a firm sleep surface on one side and an extra-firm surface on the other. High-density comfort foams and individually encased Ascension Firm coils provide sturdy support and help limit motion transfer.

Choose your size, then select the standard quilted surface or upgrade to the GlacioTex Cooling Cover on both sides. SleepCity showrooms feature the Luxe Hybrid with GlacioTex; both cover configurations are available to order.

  • Flip between the firm and extra-firm sides to fine-tune ultra-firm support for your back and stomach sleeping.
  • Up to 961 individually encased Ascension Firm coils stabilize the core, limit motion transfer, and reinforce the edges.
  • Upgrade to the optional GlacioTex Cooling Cover on both sides for a cool-to-the-touch sleep surface.
