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?

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.

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

I wanted the Plank because

"I wanted the Plank because most beds on the market sag and my back was hurting because of that. This bed does not sag at all, which is great, with that being said I am a side sleeper and so it tends to hurt my hip and shoulder. I requested a topper to try and alleviate this problem and it did help, but my hubby did not like the topper! I am trying to give it some time before making a definite decision."

— KIM S. (4/5)

Not as Firm as Expected

"I chose a 3-star rating because the mattress is not as firm as I expected. The top layer feels too much like foam, which I personally don’t like. I was looking for a truly firm mattress, but this one doesn’t provide the firmness I wanted. Unfortunately, mattresses are not something that’s easy to return, otherwise, I would return it. We’ll keep it, but I’m disappointed with the purchase. If you’re looking for a firm mattress, I would not recommend this one."

— Mila N. (3/5)

AWESOME MATTRESS

"Awesome - worth every penny. Using the extra firm side now and it’s truly a well made, Beautiful mattress. Have been looking for this type of two sided, flip-able mattress for years - since the manufacturers stopped making them and this is the real deal. Highly recommend."

— CHERYL M. (5/5)

My husband and I are

"My husband and I are both loving our new BB mattresses. After trying unsuccessfully (trialed 2 other mattresses over a nearly 2 year period) to find a bed that didn’t leave one or both of us with a sore back and/or hips, we decided to go for a split King setup. What a game changer! Now we both wake up feeling well rested and refreshed. For me, I am super glad to have found the Plank. I sleep on the softer of the 2 sides and it’s a perfect match for me. I’ve not bothered to try the other side yet but appreciate having the extra option. In contrast, my husband has found the medium Sedona to be his great match. I’m also enjoying the adjustable frame - nice to hang out reading in bed before going to sleep."

— Gretchen Y. (5/5)

Super Sleeper!

"I'm 76 with 9 surgeries from ankles to neck. My body and brain totally appreciates my new bed and adjustable frame. After a couple of weeks of playing with all the features, WOW. Since getting younger isn't an option, my new sleep team will be become even more important as I age. Also priced right with great reviews. My research paid off. more"

— Mitchell K. (5/5)

This mattress was a replacement

"This mattress was a replacement for earlier one that ended up being too soft for me. I like a very firm mattress. The Plank has a top and bottom sides that are useable. The first side I tried for 1 night. It was extremely firm. Too much even for me. I flipped it over and it has been perfect."

— Robert H. (5/5)

Let us not forget how

"Let us not forget how fun it is to unwrap! The bed is indeed firm and pleasant to sleep on. I guess you could say I don't even notice it. I've been sleeping on a Sealy firm mattress for over 30 years and this new mattress is just as comfortable."

— Frederick N. (5/5)

Firm and still comfy

"Easy delivery and set up, my husbands back is better already. I usually like soft mattresses but I actually find this very comfortable as well."

— Debby V. (5/5)

The mattress has been excellent.

"The mattress has been excellent. The only problem I had is with the delivery. I live in an apartment complex on the second floor. The box was delivered on the first floor at the opposite end of the building. I had to drag the box up a flight of stairs then drag it across the causeway to my apartment while it was raining. Since it was raining on a Sunday evening, I had not time to borrow a hand truck. I have no idea how or why anyone would think this type of delivery is acceptable."

— Rodrigue L. (4/5)

The dual firmness option was key

"I have a bad lower back and have to find the "just right" mattress to keep it happy. I prefer firm mattresses but need a little give on the top to mostly stomach sleep. I tried the firm side on the first night and found it way too firm. I tried the medium-firm side on the second night and found it almost perfect, but still a little unforgiving. I added a 2" foam topper to the medium-firm side and am now perfectly dialed in for my back. So far, with the inexpensive addition, the best mattress I've owned."

— Tom G. (5/5)
