The Plank is an all-foam mattress built for people who want the firmest sleep surface they can get. It is flippable: one side is extra firm, the other firmer still, and the brand rates it a ten on the firmness scale. High-density foams give the support while open-cell foam is meant to move heat away. It suits back and stomach sleepers and heavier sleepers who sink into softer beds, not side sleepers who need cushioning. Rivals like the Sleep On Latex or traditional innersprings offer firm support with more give; the Plank trades comfort for rigidity. It carries American Chiropractic Association endorsement for firm support.

Owners who want a very firm bed tend to be satisfied, and back and stomach sleepers report good support. Side sleepers and lighter sleepers often find it too hard, and some mention heat and edge support as weak points.
The Plank Mattress is an all-foam, flippable mattress with a pillowtop. One side is extra firm, rated a ten on the firmness scale. Flip it over for a medium-firm feel.
High-density foams give firm support. Breathable open-cell foams wick away excess body heat. The mattress is endorsed by the American Chiropractic Association (ACA), which concluded that firm support reduces spinal stress, improves lumbar support and alleviates back pain.
An optional GlacioTex™ Cooling Cover is available.
