The core difference
6-Zone Adjustment vs Fixed Hybrid Coil & Foam Mattress
iZone® Smart Bed provides three independently adjustable support zones for each sleeper, while Helix™cannot be adjusted for individual sleeper needs.
iZone® Smart Bed
Six Adjustable Zones, Three Per Side, for Back, Side & Stomach Sleepers
Six adjustable air zones, tree on each side, provide targeted support for the shoulders, lumbar region, and legs. Fine-tune lumbar support with 100 settings using the remote or app. Each sleeper enjoys personalized comfort with independent control of their side of the bed.
Helix™ Mattress
Helix™ Hybrid Coil & Foam Mattress with One Fixed Comfort Feel, No Adjustability
Helix™ provides only contouring support across the entire mattress. There is no independent adjustability for the shoulders, lumbar, or legs, and both sleepers share the same comfort feel throughout the mattress.

Does it come with an adjustable base?
The 12" Select, 14" Elevate, and 16" Prestige iZone® Smart Beds include one free.
What if it is not right for me?
You get 100 nights to decide. Risk free.
