On a scale of 1 to 10, the firm side of the Plank Firm mattress ranges between 7.5-9. This ranking is slightly above a traditional firm mattress. The ultra-firm side ranges between 9.5-10.5 — meaning it’s the firmest, flattest sleep surface on the market. To put that in perspective, next level firmness could only be achieved by sleeping directly on the floor with no pressure point relief.

The flippable design of the Plank Firm mattress allows you to choose your ideal firmness level. A .75” quilted top layer, patterned with continuous stitching, ensures zero loft for an ultra-firm sleep experience. Or, flip the mattress, and a .75” quilted layer, patterned with tack-and-jump stitching, creates minimal loft for a firm sleep experience. Next level firmness can be achieved by eliminating the mattress altogether and sleeping directly on the floor. You will, however, lose some of the pressure point relief that comes with sleeping on an actual mattress.

The Plank Firm by Brooklyn Bedding is an all-foam mattress—and the firmest sleep experience on the market. (Next level firmness could only be achieved by eliminating the mattress altogether and sleeping directly on the floor.) Meanwhile, the Plank Firm Luxe by Brooklyn Bedding is constructed with added foam layers and individually encased coils to deliver greater pressure point relief and responsiveness. Both mattresses are flippable, which allows you to choose between a firm and extra-firm side. Many customers with a sleep partner do opt for the Plank Firm Luxe to ensure a more comfortable sleep experience for both individuals.

The Plank Firm features a breathable quilted top on either side of the mattress, coupled with open cell technology throughout the foam layers, to help ensure a neutral temperature environment.

For even greater temperature moderation, a GlacioTex™ Cooling Cover can be sewn into the Plank Firm mattress as an optional feature—just look for the "Add Glaciotex™ Cooling Cover” option on the right side of the product page when making your selection. Once you add this feature to your mattress, the cooling top panel will be sewn into the surface of the mattress to deliver ultimate cooling on contact

The GlacioTex™ Cooling Cover is an optional feature that does not impact the comfort, firmness level, or support of the Plank Firm mattress.

The height of the Plank Firm mattress is 10”. An illustration of the mattress with details for each layer is found on the product page, along with a full product description.
