Firm design for those in need





Add GlacioTex™ Cooling Cover

The Plank Firm mattress allows sleepers to gain the health benefits of a very firm mattress—while enjoying a similar feel to the firm, flat sleeping mats found in the Far East. This flippable mattress allows you to choose between firm and very firm with a simple rotation of your mattress. Add the optional GlacioTex™ Cooling Cover to gain the perfectly cool sleep temperature.

Available in both all-foam and hybrid, sleepers can opt for an ultra-firm mattress or a firm mattress with an inner coil system for a more responsive feel. (Available exclusively from Brooklyn Bedding.)

  • Flippable design in dual-option firmness levels.
  • Endorsed by the American Chiropractic Association (ACA). A careful three month evaluation found that the Plank Luxe and Plank All-Foam were able to reduce spinal stress, improve lumbar support, and alleviate accompanying reports of back pain.
  • Select “Add GlacioTex™ Cooling Cover” and we’ll sew our dynamically cooling cover made from PCM fabric onto your mattress to provide you with the perfect sleep temperature.
  • Bed-in-a-box delivery allows for quick shipping and easy maneuverability to your bedroom. (Expands in minutes.)
  • Free shipping to the 48 contiguous states.
  • 10-year warranty.
  • 120-night risk free trial.
  • Side 1: The traditional firm sleep surface provides cushion for joints while also providing   durability and support for your hips to help alleviate back pain (ideal for plus size or larger build sleepers who sleep on their back).
  • .75 quilted top layer, patterned with continuous stitching, ensures an ultra-firm sleep experience.

  • Side 2: The ultra firm sleep surface provides some cushion for joints while providing durability, support for your hips, and the flattest sleep surface possible.
  • 1.5” quilted top layer with tack-and-jump stitching is paired with a 2” premium memory foam comfort layer, creating a traditional firm sleep experience.
  • Side 1: The traditional firm side of this mattress is engineered to promote the neutral alignment of your spine in order to alleviate back pain and prevent sleep apnea.
  • 1.5” quilted top layer with tack-and-jump stitching—paired with a 1” premium memory foam comfort layer and a 2” high-density support layer.

  • Side 2: The ultra-firm side of this mattress pairs with an innerspring core to promote both pressure point relief and better spinal alignment (ideal for back sleepers with a larger build).
  • .75” quilted top layer with continuous stitching—paired solely with a 2” high-density support layer—ensures an ultra-firm sleep experience.
  • 6” core of individually encased Ascension Firm coils delivers contouring responsiveness and pressure point relief.
  • More compatible with adjustable power bases and taller headboards due to this model’s higher profile build.

“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 comes in at 11.75 inches and the Plank Firm Luxe comes in at 13.25 inches (both are in the average range for modern mattresses). 

For an illustration of each mattress, a detailed description of each layer, and a full product description, please visit our Plank Firm product page here.
We believe the only way to achieve a more firm sleep experience is to opt for the floor—an option we caution against as your body may quickly begin to feel stiff due to the absence of our mattress’s pressure relief system or feel sick from allergens and dust mites that accumulate on the floor. 

Please note: Both the Plank Firm and the Plank Firm Luxe are flippable designs, allowing you to choose between a truly firm .75 inch quilted layer on one side or a medium firm 1.5 quilted layer on the other side. 
Both the Plank Firm and the Plank Firm Luxe vary in weight starting at roughly 60 pounds for a twin to 105 pounds for a king. 

For the dimensions of each mattress size, please consult our information graphic here
Both the Plank Firm and the Plank Firm Luxe sport a breathable quilted top fabric and layers of high quality foam. Each of these quality foam layers feature open cell technology—ensuring a neutral temperature environment. 

For additional cooling comfort, you may select our GlacioTex™ Cooling Cover, which offers dynamic cooling from PCMs so you’re never too hot or too cold. (Our skilled craftsmen will sew this cooling cover onto the mattress’s surface for cooling on contact. Simply select “Add Cooling Top Panel” at your time of purchase.)
Since the GlacioTex™ Cooling Cover is about as thin as a typical bed sheet, this technologically-advanced cooling layer preserves the mattress’s firmness, comfort, and height—you simply gain a cooler night’s sleep. (This optional cooling panel is sewn on as the mattress’s top layer.)
On a scale of 1 to 10, the truly firm side of the Plank Firm ranges from a 9.5 to a 10.5 on the firmness scale—making this mattress the firmest, flatest, and healthiest sleep on the market. 

The medium-firm side of the Plank Firm ranges from a 7.5 to a 9 on the firmness scale.

The Plank Firm Luxe is slightly less firm. The medium firm side of this mattress ranges from a 6.5 to an 8 on the firmness scale (a traditionally firm mattress range). While the truly firm side ranges from a 7.5 to a 9.5 on the firmness scale. 
The Plank Firm is an all foam mattress, made with the highest quality layers of foam available and engineered to be as firm as possible, as such, the mattress’s edge support is higher than a typical foam mattress. 

For additional edge support, we recommend the Plank Firm Luxe which includes a core of individually encased coils—and surrounding the mattress’s edges, we add higher gauge coils (meaning, smaller and more tightly wound coils) for unparalleled edge support. 
Both Plank Firm models are engineered to support as much as 950 pounds—a standard feature of all Brooklyn Bedding mattresses. However, if you are looking for a mattress built for a plus size sleeper (or a plus size partner), please consider our Titan mattress, found here
Any mattress foundation with slats no more than 4 inches apart will work well with any of our mattresses. While a mattress foundation is not necessary, please be sure that the mattress rests on a surface with minimal to no flex. 

If you prefer a foundation, please see our Brooklyn Bedding foundations here.
We encourage you to rotate your mattress every 6 to 8 months for optimal and sustained flatness. However, it is not necessary to flip either Plank Firm model—unless you wish to change the firmness level of your sleep experience.
The Plank Firm is an all-foam mattress—while the Plank Firm Luxe is made from the same high quality foam layers, but with the addition of our high-quality, individually encased coils for increased pressure relief and responsiveness. 
We are confident that we are providing you with the very best bedding available. If for any reason, you decide that our mattress does not fit your needs, we ask that you first try the mattress for 30 nights from the date of delivery in order to properly adjust to the new mattress. 

Then, if you are still unsatisfied with your mattress, we will gladly refund your purchase within our generous 120 night risk-free trial period.
