Why Plank Luxe is the Best Firm Mattress

Video Thumbnail

American Chiropractic Association Approved 
Endorsed by the American Chiropractic Association (ACA), this luxe design was shown in a 3-month study to reduce spinal stress, improve lumbar support, and help alleviate back pain–one of the reasons it’s recognized as a best mattress for back pain.

Firmest Hybrid 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

Choice of Firmer or Firmest  
Change it up—will it be firmer or firmest? The choice is yours with a simple flip of the mattress (This flippable design improves the longevity of your mattress) 

Time-honored Sleep Design 
Our firm design is borrowed from the wisdom of the ancients who created Tatami mats—while offering the modern look and comfort of a traditional mattress 

More Than Just Firm, Made for Comfort

Frequently Asked Questions

How firm is the Plank Firm Luxe?

On a scale of 1 to 10, the firm side of the Plank Firm Luxe mattress ranges between 7.5-8. This ranking is deemed a traditional firm mattress. The ultra-firm side ranges between 9.5-10—meaning it’s one of the firmest, flattest sleep surfaces on the market but features more contouring than the original Plank Firm version.

What are the cooling features available for the Plank Firm Luxe?

First, the Plank Firm Luxe 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. Second, the Plank Firm Luxe mattress is constructed with individually encased coils, which allow for greater airflow.

For even greater temperature moderation, a GlacioTex™ Cooling Cover can be sewn into the Plank Firm Luxe 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 Luxe mattress.

How much does the Plank Firm Luxe weigh and what are it's dimensions?

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

What type of foundation works best for this mattress?

What differentiates the Plank Firm from the Plank Firm Luxe by Brooklyn Bedding?

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.

What is the height of the Plank Firm Luxe?

The height of the Plank Firm Luxe mattress is 13”. An illustration of the mattress with details for each layer is found on the product page, along with a full product description.

How much weight will the mattress support?

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—you can check out the Titan Plus Mattress by Brooklyn Bedding here.

Is the Plank Firm Luxe flippable?

The Plank Firm and Plank Firm Luxe mattresses are designed with varying firmness levels on either side of the mattress and can be flipped to customize your sleep experience.

Where is this product made?

This product is made in America using foreign and domestic components.

Do your mattresses have any safety certifications?

Every Brooklyn Bedding mattress is assembled in our Arizona facility, allowing us to ensure the highest quality every single time. Our mattresses are GREENGUARD Gold Certified and made with CertiPUR-US certified foams, which guarantees they are made without any harmful chemicals including ozone depleters, PBDE flame retardants, mercury, lead, heavy metals, formaldehyde, and have extremely low impact on indoor air quality.

Reviews

King short plank mattress

"This was a vast improvement over the original RV mattress. We tried a mattress topper first but that did not work. Manufacturing and delivery was fast. I called to verify shipping date and the customer service was great!"

— Stann M. (5/5)

Disappointed

"Initially the mattress was very firm. After about a week it, I noticed it getting soft. I've flipped the mattress around but the issue is still the same. Last night, after about 2 months of sleeping on the mattress, I noticed that indentations and sinkage on the extra-firm side. For reference, I weigh 105lb. My experience has been disappointing and I'm looking to return this."

— Yeefung T. (2/5)

Plank Mattress Delivers Again

"The mattress is everything I expected from Plank Mattress. The mattress is firm and comfortable and made with high quality materials. This is our third mattress (for an extra bedroom and larger mattress) from Plank, so that says a lot about our opinion of the mattress."

— Kurt W. (5/5)

Good firmness.

"I like a firm mattress and the Plank Luxe Mattress Twin XL is comfortable and has the good firmness I am looking for. I use the ultra-firm side. I've been sleeping on it for a few weeks now and I do like it. It also has a quality build that should last some years to come. This was a good purchase for me."

— ROLAND H. (5/5)

Great Deal!

"74 years young 210lbs, never thought a thousand dollar mattress would work for me. This mattress made a believer out of me. Today is day 118 and I checked the mattress with a level and no sags at all. Sleeping great and that is what is what counts, returned a three thousand dollar mattress to another company that gave me back pain. If I can get 2 years out of this one I'll be happy to buy another one."

— Frank (5/5)

Love that it is reversible.

"Love that it is reversible. The extra-firm is perfect for us. Motion isolation is good, and my back feels great, which it doesn't after sleeping on softer mattresses."

— Michelle S. (5/5)

Could this be the one?

"First off, love that they could get an innerspring mattress into a box. It made it easier to drag up 7 flights of stairs. I can't imagine doing it fully expanded. 😨 I'm sleeping on the Extra Firm side (I think, 💎 pattern = extra firm) and let me tell you, my back hasn't felt this good since I was a teenager. I'm a stomach sleeper and it's sheer bliss(I also lost weight so that helps too). I don't sink into the bed. Surprisingly enough, I can fall asleep on my side and EVEN MY BACK 🫢. I can never fall asleep in my back. . . . Can this be magic? The cooling mattress protector. . . . OMG I've never been able to sleep in a room at 78°F with a blanket and only a fan blowing. I would be in a puddle the whole night. Not with this mattress. New achievement unlocked! The cooling gel works. It really does move the heat away from you. All you need is a fan to move air past it and you got yourself an "air conditioned bed". Very pleased since I've always looked cooler temps because of the hot sleeping. So far I love everything about it. The only thing I can't rate is durability. My last mattress developed a hole where I slept after 1. 5 years. I wanted a hybrid this time hoping it will last longer than 5 years and not torture me along the way. I have hopes for this mattress. It's solid, it's heavy, its well built and double sided. If one side wears out, in theory, I should be able to flip it to get a new mattress."

— Janusz C. (5/5)

So far, so good! We’re

"So far, so good! We’re really happy with the mattress. Also the fact that we can flip it, which seems to be rare nowadays. Easy to purchase online. The delivery was very prompt. The package was easy to access and open and set up was a breeze. We have an Olympic queen size bed, and this will be the for our needs in the future too"

— John T. (5/5)

I love this mattress! I

"I love this mattress! I was waking up with back pain constantly but was leery of ultra firm mattresses. I did not need to be worried because this is the best mattress I have ever had. It's firm but yet still is soft and supportive where I need it. I've had it for about two weeks now and NO back pain in the mornings! I sleep really well too and feel like I don't toss and turn all night as I did before. Really great purchase. So happy :)"

— Ellen F. (5/5)

A Mattress That Made a Real Difference

"I like my Plank mattress. After years of waking up stiff and dealing with back pain, I noticed a difference within the first week. I have less pain, greater flexibility, and wake up feeling better than I have in years. I started on the Firm side for the first week, then flipped it to the Extra Firm side. While it’s definitely a firm mattress, it doesn’t feel hard. It provides excellent support while still being surprisingly comfortable."

— Steven W. (5/5)
