Plank Luxe Zoned: two firm feels with zoned support
The Plank Luxe Zoned is a flippable hybrid designed with a firm side and an extra-firm side. Its foam-and-coil construction includes reinforced foam through the center third, according to Plank. Flip the mattress to change surfaces; both are intended for people who prefer a firm feel.
Inside the mattress
Plank lists these layers from the firm side toward the extra-firm side:
- Quilt foam: 1.5 inches. Firm surface cushioning.
- Zoned lumbar-support foam: 1.5 inches. Added reinforcement through the center third.
- VX 2.5 responsive foam: 1 inch. Responsive cushioning above the coil unit.
- Ascension® Max coils: 6 inches. Individually encased support coils.
- VariFlex™ transition foam: 1 inch. A responsive layer on the reverse side.
- Zoned lumbar-support foam: 1.5 inches. Center-third reinforcement on the reverse side.
- Quilt foam: 0.75 inch. The flatter, extra-firm surface.
Plank also offers an optional GlacioTex cooling cover. Construction details are manufacturer specifications and may change.
Who might like it?
- Firm-mattress shoppers who want two surfaces to choose from.
- Back or stomach sleepers looking for a firm hybrid with zoned center support.
- Side sleepers who prefer a firm mattress and want to try the more cushioned firm side. Those who need significant shoulder or hip relief may prefer a softer mattress.
Comfort and pressure relief depend on the sleeper. Flipping a hybrid can take two people; follow the manufacturer’s care instructions.
