Plank Mattress Highlights
The Plank mattress by Brooklyn Bedding is a dual-sided all-foam mattress that offers different firmness levels on each side. If the typical firm mattress is never quite firm enough for you, the Plank may be just what you’ve been looking for.
In this review, you’ll see how the Plank mattress performed during our in-house testing along with everything else you should know to decide if the Plank is the right ultra-firm mattress for you.
What makes is special:
- The Plank mattress is a dual-sided all-foam mattress designed for those who find most firm beds too soft. This flippable mattress offers a firm (7/10) and ultra-firm (9/10) side allowing you to choose which works best for you. The extra-firm side of the mattress is one of the firmest sleeping surfaces that we’ve come across.
- Designed with Brooklyn Bedding’s transitional TitanFlex foam, the Plank offers outstanding support, durability, and pressure relief. This allows for improved blood flow and better support for your lower back so you can rest peacefully all night long.
- The quilted top and bottom layers are uniquely stitched to provide the most firmness and least loft.
- An optional cooling panel offers temperature-regulating phase-change material for an incredibly cool night’s sleep.
- It’s one of our top-rated best firm mattresses!

Plank Highlights
✅ Pros
- Pressure point relief: The Plank mattress is one of very few extra-firm beds that delivers excellent pressure point relief—although most side sleepers would still do better on a softer mattress.
- Proper spine alignment: The Plank is designed for healthy back support, and we confirmed this benefit during our in-house testing.
- Easy to move around on: This mattress is responsive, which means it’s easy to switch positions and get comfy—great for combination sleepers.
- Durable: Thanks to its high-density foam construction, the Plank is more durable than the average all-foam bed.
❌ Cons
- Costs more for optimal cooling: While the baseline Plank is cool for an all-foam mattress, hot sleepers should consider the optional cooling panel. However, this costs an extra $250 for the queen-size mattress.
- Off-gassing: While we didn’t notice much of an odor when we unboxed our Plank, some reviewers have noted a scent that lasts for up to a couple of days. Don’t worry, this odor will fade, and it’s quite normal for an all-foam mattress that comes compressed in a box.
Pressure Relief
When buying a firm mattress, it’s hard to find one that also cushions pressure points. And for side and back sleepers, you need a mattress that removes weight from areas like the lower back, hips, and shoulders.
We use a pressure mapping film to locate problematic areas of high pressure, which show up as red zones. As you can see from the images below, there was zero red when our sleep tester was on their back or side! For a firm mattress, that level of pressure relief is nearly unheard of. Brooklyn Bedding’s proprietary foam technology does an incredible job of contouring while maintaining firm support.
Motion Isolation
One of the most important factors for couples to consider when buying a mattress is how well it stops motion from traveling from one side of the bed to the other. We conduct two tests to see how well a mattress isolates movement.
In the first, our sleep testers lie next to one another and take turns switching from one position to the next, while the other person sees how much movement they feel. When our sleep subjects tossed and turned on the Plank, the other person could feel it. However, the surface wasn’t too shaky. They gave the Plank an 8 for the first part of our motion transfer test.
During the next test, we place a glass of red wine on one side of the bed and have one of our sleep testers move around on the other side. The wine had a little jiggle to it, but nothing too severe, earning it an 8/10 in this test, too.
Spine Alignment
There’s a movement surrounding the benefits of sleeping on hard surfaces. Some people are choosing to sleep on the floor in the hopes of improved posture and spine positioning, potentially reducing back pain and body aches over time.
The Plank mattress is designed for people who want to reap the benefits of sleeping on a hard surface but without having to sleep directly on the floor. In our spine alignment test, we were impressed by how straight the spines of our sleep testers were. A straight spine while on your side is a healthy spine, and the balanced firmness also cradles the spine’s natural curvature when lying on your back.
How Firm is Plank?
The Plank is one of the firmest mattresses available. Its dual-sided design boasts one firm side and one extra-firm side. The firm side has a firmness level of 7/10 and the firmer side a 9/10.
What Sleeping Position Works Best?
Thanks to the Plank’s firm feel, it’s a top back sleeper mattress and stomach sleeper mattress for sleepers who prefer a firm bed. It’s also a great mattress for combination sleepers who spend most of their time on their backs or stomachs – they can also enjoy the Plank thanks to its excellent responsiveness.
Firm beds usually aren’t great for side sleepers. Their hips and shoulders need to sink in further to cushion their pressure points and keep their spine aligned. That being said, our test proved that side sleepers can get both of these things from Plank; therefore, it could work well for side sleepers who prefer to sleep on the mattress rather than in. If you want to compare it to other options, head over to our best mattress for side sleepers page.
Temperature Regulation
We tested the Plank mattress without the optional cooling panel. Without the cooling panel, the Plank earned an 8/10 for its cooling properties. With the cooling panel, the Plank is a good mattress for hot sleepers. They sew extra cooling properties into the cover of the mattress, making it a cool-to-the-touch bed.
Weight Limit
When we spoke with Brooklyn Bedding customer service, we were told that the Plank doesn’t have a weight limit. Thanks to its firmness and durable high-density foam, this mattress excels for people of most sizes and body types who want a bed with an incredibly firm feel.
What Foundations Are Compatible?
The Plank mattress can be used on most foundations that provide minimal to no flex. This includes box springs, adjustable frames, platform beds, or slatted bed frames. Brooklyn Bedding also offers specially designed foundations.
A Look Inside
The Plank is a dual-sided all-foam mattress made from two foam layers and unique quilted tops on both sides.
- Quilted top layer: A thin quilted top that utilizes continuous stitching for zero loft and a flat, smooth sleeping surface. This is the ultra-firm side of the mattress.
- TitanFlex foam: Ultra-firm proprietary TitanFlex foam is a latex alternative that delivers excellent firmness, support, and pressure relief.
- High-density base foam: High-density polyfoam makes up the Plank’s core. It adds durability, motion isolation, and firmness.
- Quilted top layer: A thicker quilted comfort layer with minimal loft for a bit more cushion than the firmer side.
- Optional cooling panel: A unique phase change material fabric can be added for an extra-cool sleeping surface. This add-on includes a cooling panel for both sides of the mattress.

Ease of Setup
The Plank mattress took us exactly a minute and a half to unbox. The mattress was not very heavy and had a mild smell (not too much chemical off-gassing). There was a lot of wrapping, but the Plank took its full shape immediately.

How Long Is the Sleep Trial?
You have 120 nights to try the Plank mattress in the comfort of your home. You can return the mattress during the 120-night sleep trial for a full refund. But there is one caveat—Brooklyn Bedding asks that you give the mattress a chance for 30 days. It takes time for your body to adjust to a new mattress, so it’s best to try it out for a full month to see if it’s what you’d hoped it would be.

Brooklyn Bedding mattresses come with the industry-standard 10-year warranty. If you have a problem during this time that you believe is a defect in the mattress, contact BB’s customer service team to submit a claim.

Should You Buy Plank?
The Plank mattress is one of the best all-foam beds for firm mattress lovers. Its double-sided firmness levels allow you to choose between a standard firm and an ultra-firm. And what we love about this firm foam mattress is that it offers greater pressure relief than the vast majority of firm beds out there.
Another great thing about the Plank is that it was built to be supportive and durable. Its high-density foam construction has no set weight limit as it’s designed to support every body size. And with an optional cooling panel, it’s an excellent bed for hot sleepers.
The only people that we would advise against buying the Plank are those who need extra cushion. If you’re a side sleeper, chances are you’re going to experience fewer aches and pains on a medium-firm or softer bed. We recommend the Layla Hybrid as a flippable alternative if this is you.

The Plank vs Other Firm Mattresses
The Plank is one of very few all-foam mattresses that’s designed for those who find most beds too soft. Most firm beds are innerspring beds or hybrid mattresses with thin layers of foam. Because of this, the Plank provides superior pressure relief, perfect for back, stomach, and combination sleepers.
Thanks to its all-foam construction, the Plank is better than the average extra-firm bed for couples. Without innerspring coils, the Plank does a good job at minimizing motion transfer for a bed that’s extra-firm.
The Plank vs Other Brooklyn Bedding Mattresses
Brooklyn Bedding manufactures a wide variety of high-quality foam and hybrid mattresses. Here’s a breakdown of how the Plank compares to each BB mattress model.
- Plank vs Titan: The Titan is a foam and hybrid mattress designed for plus-size sleepers. It too is a firm bed, with a firmness that falls between the firm and extra-firm sides of the Plank. During our in-house testing, we found the Titan to offer better motion isolation, ease-of-movement, and spine alignment. The Plank earned higher scores in pressure relief and edge support. Read our Titan mattress review.
- Plank vs Signature: The Signature is a hybrid mattress with three firmness levels: soft, medium, and firm. The firm falls between the firm and extra-firm sides of the Plank. Both beds earned an outstanding 9.1/10 in our testing, although the Plank does do a better job limiting motion transfer. Read our Brooklyn Signature mattress review.
- Plank vs Sedona: The Sedona is Brooklyn Bedding’s most luxurious mattress. Its hybrid construction boasts deeply hugging memory foam and responsive innerspring coils. Its medium feel is much softer than the 100% polyfoam Plank. The Sedona’s plush comfort layers are better for side sleepers and people who like a memory foam feel. The Plank is best for people who prefer extra-firm beds.
- Plank vs Spartan: The Spartan is a luxury hybrid mattress with a feel much different than the all-foam Plank. Innerspring coils deliver a slightly bouncier surface, while thick comfort layers of memory foam and polyfoam offer a balance between softness and support. The Spartan comes in soft, medium, or firm but is only one-sided. The Plank is firmer and has a distinct all-foam feel, with the less firm side slightly softer than the Spartan firm and the extra-firm side firmer. Read our Titan mattress review.
- Plank vs Bloom: The Bloom and Plank are vastly different beds. The Bloom is an eco-friendly hybrid mattress with a medium firmness level. Its top layer of cotton and wool is quite plush, while the latex and innerspring support layers balance support and pressure relief. The Plank is much firmer, dual-sided and is made entirely of polyurethane foam. The Bloom is better for the average sleeper and the Plank for anyone who needs extra firmness and support. Read our Bloom Hybrid mattress review.
- Plank vs Bowery Hybrid: The Bowery Hybrid is softer than the Plank and uses pocketed coils rather than high-density foam for its support. The Bowery does a better job at minimizing motion transfer. Combined with even sturdier edges, and the Bowery is typically a superior bed for couples. The Bowery Hybrid is much less expensive than the dual-sided Plank, but the Plank is more durable. Read our Bowery Hybrid mattress review.
- Plank vs Aurora: The Aurora is a hybrid bed that comes in multiple firmness options. The plush, medium, and firm Aurora mattresses are each softer than the Plank all-foam mattress. Opt for the Plank if you want extra-firm support and the Aurora for a more balanced feel. Read our Brooklyn Aurora mattress review.

Q.
Do I need to use a Brooklyn Bedding foundation with my new mattress?
A.
No. While their bed frames and foundations are designed for their beds, that does not mean others won’t work well. Just be sure that whatever you use is in good condition and doesn’t allow for much flex.
Q.
I spilled something on my new Plank mattress. Can I still return it?
A.
Potentially yes, potentially no. It all depends on if the mattress is in good enough condition to be accepted by a local charity for donation. Damage can void the trial period, as well as the warranty. This is why we recommend that you use a waterproof mattress protector from day one on any new bed.
Q.
Is the Plank better than sleeping directly on the floor?
A.
There are many proponents of the ultra-firm sleeping surface. We tend to advise extra-firm mattresses over directly sleeping on the floor for a few reasons. The first is that your joints need a bit of cushion to avoid pressure and pain, which is provided by firm beds. Second, sleeping on the floor puts you at the same level as allergens like dust and pests like spiders or mice. Sleeping on a bed can help you breathe better and sleep more soundly.
