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

High Density Foams 
Our foams are thick and dense (and made with the highest quality materials!) to give you firm support while soothing hips and shoulders for long-lasting 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?

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 5" apart, wood or metal box foundations, and solid wood or metal platforms. If you need a foundation for your new mattress, check out our foundations specifically designed for Brooklyn Bedding mattresses here.

How does the 120-night trial period work?

If during your 120-night sleep trial (which begins once you receive 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. 

Please allow 30 days to laps from the date of delivery before beginning the return process.

Customers are able to make use of this 120-night comfort trial on one occasion. The second occasion is not eligible for a return.

Please contact us at support@brooklynbedding.com with “Return Request” in the subject line, and we will respond quickly to process your request. 

Please Note: No returns or exchanges will be offered on clearance items.

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

Happy with purchase!

"Very happy with the mattress! We got the cooling cover and are happy to say it is definitely NOT hot. What an upgrade over a typical foam heat trapper! We are using it on the extra firm side and are happy, although might flip it over just to try the other side! So far so good, we are pleased with the mattress."

— Paloma E. (5/5)

Positive results

"It’s been a couple weeks since I got this mattress. I can’t say much about the ‘cooling technology’ as I still get hot while sleeping, but the mattress quality and firmness is very good. My lower back would tighten up so much worse than it does now after 2 weeks. I’m hoping it continues to improve. I’m going to flip the mattress over to the ultra firm side and try that out next."

— Patrick R. (4/5)

If Firm is Your Desire

"The Plank Luxe is the best firm mattress that I have ever purchased. Being someone with multiple back surgeries it has increased my sleep duration. I was hesitant to purchase a mattress in a box, but it has been a good decision."

— Robbie A. (4/5)

Plank Luxe review

"It's a nice bed overall, but unfortunately it was not as firm as I was expecting. It is firmer than most on the market I will say, but less so than what I was hoping to experience. The outer 25% of the mattress seem to be the firmer sections, I just wish it was as firm throughout, especially in the middle. I have a steel frame with no bowing or bending in it, so unfortunately I don't believe there is a remedy for the firming issue. I recently bought a couch off of Amazon, at the same time I purchased the Luxe. The couch is the firmest piece of furniture I have ever sat or laid down on, and now I am pondering returning the Luxe and purchasing another couch to convert into a bed. The couch is what I hoped my Plank would feel like. I suppose I prefer an absurd amount of firmness, however. Maybe its just me."

— Christopher J. (3/5)

Firm as it indicates

"Double side is good . We used to get a really firm mattresses but can't find it anymore in the market. Everytime we bought indicate as firm but not actually firmly to us. This matress is actually firm to us and maybe too firm in one side. Good thing it has double side that we can choose which side is good to us."

— Kuo L. (5/5)

Sturdy marress. Maybe too sturdy?

"I bought my mattress in April, and it has been a tough transition. I developped leg, knee, and hip aches from sleeping on my mattress that I didn't have when sleeping on my old mattress. I tried the less firm side and still have the same aches and pains. I started sleeping on my couch and the aches stopped. I will be looking at mattress toppers to try and find a remedy."

— Matt W. (2/5)

Great purchase for lower back pain!

"Loving this mattress so far. After being overseas and realizing how much the firmer mattress helped my lower back pain, I knew I needed something new. I have been using the less firm side and it is definitely helping. It also does not feel too firm to sleep on my side sometimes."

— Ariana B. (5/5)

I would recommend to memory foam lovers

"This mattress is great for people that likes memory foam. I got the 75% firm. I should have gotten the 100% firm. But my body is not in pain after sleeping on it. The box that it was delivered in looked like someone played kickball with it for a few weeks. Thankfully the mattress was in great condition. The height is high for us height called people but I could tell from the pic, so I planned correctly for it."

— Katrina E. (4/5)

At first restless sleeping because

"At first restless sleeping because of extra firm side not used to it switched to firm side and a bit better sleep now will try firm side again. . . . ."

— Gary S. (5/5)

Love mattress, Base needs modification

"Love my recently purchased Twin Firm Luxe. Exactly what I needed for my lower back pain. However, the foundation needs some modification. It needs some sort of lip or raised edge to keep the mattress in place. Sit on the edge of the bed and the mattress slides across the foundation. Not much, but enough that it is irritating to have to keep pulling mattress back into square with base."

— Pauline H. (4/5)
