$749 $561.80






Add GlacioTex™️ Cooling Cover

Firmly ACA Endorsed

The American Chiropractic Association (ACA) concluded that the mattress’s firm support reduces spinal stress, improves lumbar support, and alleviates back pain 

Firmest All-foam Mattress on the Market 

Never feel your back dip and never opt for the floor again. The extra firm support (a ten on the firmness scale) will keep you firmly supported all night long

Flippable All-Foam 

If your extra firm mattress feels too firm, simply flip the mattress to achieve a medium-firm feel. Flip for firm or firmest—the choice is yours. (Plus, the flippable design improves the longevity of the mattress.) 

Time-honored Sleep Design 

Our firm design is borrowed from the wisdom of the ancients who slept on firm pads or tatami mats. Our design offers all the benefits of these time-honored traditions while providing a more modern look

“Our Editor’s Pick is the Plank mattress from Brooklyn Bedding, a flippable mattress with one side that is ‘Firm’ (or 8 on the 1-10 firmness scale) and another side that is ‘Extra Firm’ (or 10).”


“Those in the market for a firm bed now have a dual-sided choice…well-supported and comfortable in Plank, a new product from Brooklyn Bedding.”


“The Plank by Brooklyn Bedding mattress is the firmest 2-sided bed on the market.”




The height of the Plank Firm mattress is 10.25”. An illustration of the mattress with details for each layer is found on the product page, along with a full product description.

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 1.5” 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 weight of the mattress and its dimensions vary by selection. The Plank Firm mattress weighs between 60-105 pounds. Dimensions for mattress sizes can be found in the graphic here:

Any type of support system that provides minimal to no flex will work with our mattress. This includes most platform, slat, and box spring foundations. If you need a foundation for your new mattress, check out our foundations specifically designed for Brooklyn Bedding mattresses here.
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 cooling panel can be added to 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 GlacioTex™ Cooling Cover will be sewn into the surface of the mattress to moderate temperature while delivering ultimate cooling on contact.
Brooklyn Bedding mattresses are designed to be used on foundations with solid support with minimal to no flex. This includes slatted wood or metal foundations with slats no more than 4" apart, wood or metal box foundations, and solid wood or metal platforms.
The GlacioTex™ Cooling Cover is an optional feature that does not impact the comfort, firmness level, or support of the Plank Firm mattress. What it does affect is temperature moderation—providing cooling relief on contact. This added feature can be especially important to sleepers who tend to experience night sweats or otherwise sleep too hot. Because the optional GlacioTex™ Cooling Cover is sewn into the surface of the mattress, the height of the mattress remains 11.75” tall.
Most Brooklyn Bedding mattresses should be rotated every 6 to 8 months but never flipped (or inverted). Our mattresses are designed with comfort layers on top and support layers on bottom, including individually encased coils in hybrid models. We also use higher quality materials that last much longer than traditional mattresses. The exceptions to the “no flip” rule are the Plank Firm and Plank Firm Luxe mattresses by Brooklyn Bedding, the EcoSleep by Brooklyn Bedding and the Propel Dual-Sided All-Foam and Propel Dual-Sided Hybrid mattresses by Brooklyn Bedding. These mattresses are designed with varying firmness levels on either side of the mattress and can be flipped to customize your sleep experience.
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 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 mattress by Brooklyn Bedding is engineered to be the firmest, flattest sleep possible. Edge support on both sides of the mattress will be firmer than a typical all-foam mattress.
All Brooklyn Bedding mattresses are designed to support up to 950 pounds. If you or your sleep partner weigh more than 300 pounds—and prefer more substantial support as well—you can check out the Titan Plus Mattress series by Brooklyn Bedding here.

If during your 120-night sleep trial (which begins once you have received your new mattress), you decide that you are not completely happy with your mattress and wish to return it, we will help dispose of your mattress and help you begin your return.

Our mattresses are made in America using foreign and domestic components.

Extra firm mattresses are highly favored by back and stomach sleepers for their superior support, crucial for maintaining proper spinal alignment and preventing overarching of the spine, especially in these sleeping positions. By providing a firm surface, they distribute body weight evenly, reducing pressure point pain and promoting restful sleep. To enhance comfort without compromising firmness, incorporating a cooling mattress topper can be transformative, regulating temperature and wicking away moisture for night sweats and hot sleepers. This combination of an extra firm mattress with a cooling topper offers optimal support for spinal alignment and enhanced comfort, ideal for those prioritizing back health and seeking relief from pressure point pain while ensuring a cooler and more comfortable sleep surface.

The Plank mattress is highly recommended for individuals with back pain, offering superior spinal stress reduction, enhanced lumbar support, and improved sleep quality. Its unique design and firmness ensure proper spinal alignment, crucial for alleviating back pain, while premium materials provide exceptional comfort. With a 6” high-density foam layer engineered for pressure relief, the Plank mattress cradles pressure points and promotes proper spinal alignment, reducing stiffness upon waking. Crafted to contour to the body's curves, it minimizes strain on back muscles and enhances overall comfort and sleep quality, while also isolating motion for undisturbed sleep, particularly beneficial for couples. Endorsed by the American Chiropractic Association and praised by customers for significantly reducing back pain, the Plank mattress offers an optimal sleep surface for feeling refreshed and revitalized each morning.

Yes, the Plank mattress is CertiPUR-US Certified. CertiPur-Us Certified means that it meets rigorous standards for emissions, content, performance, and durability, ensuring a high-quality and safe sleeping environment.
