Brooklyn Bedding Plank Firm Mattress Video Review
Take the Plank Firm for a (vicarious) test drive with our in-depth video review! Our reviewer, Joe, will walk you through each layer of this bed’s construction and share his experiences with sleeping in every position on the Plank Firm.
Brooklyn Bedding Plank Firm Firmness And Feel
When you’re evaluating any mattress, it helps to start by considering firmness and feel. These factors will have a big impact on whether a given bed is well-suited to your preferred sleep position(s) and other sleep needs. So let’s dive in: Here’s a look at the Plank Firm’s firmness and feel!
How Firm Is The Brooklyn Bedding Plank Firm?
We ranked the firm side of the Plank Firm around an 8 out of 10 on the firmness scale, and we ranked the extra-firm side close to 9/10. The industry standard for average firmness is 6.5/10, so both sides of this mattress are significantly firmer than average. In fact, the extra-firm side is one of the firmest sleeping surfaces we’ve ever experienced. The bed is explicitly designed to create a very firm and very flat sleeping surface with no loft for sleepers to sink into.
Firmness is a bit subjective, so it’s possible that your assessment might vary a touch. But it’s safe to say that everyone will agree this is a very firm mattress.
Sleeping On The Brooklyn Bedding Plank Firm
Now, let’s talk about what it feels like to sleep on both sides of the Plank mattress.
We found the extra-firm side of the Plank Firm to be a bit too firm for back sleeping. Because the mattress is so firm and so flat, it doesn’t allow our hips to sink in a bit for any pressure relief.
Not surprisingly, this side is much too firm for side sleeping. There’s no “give” from the mattress, so we experienced a lot of pressure around the shoulder and hip.
This side proved to be a great match for stomach sleeping. It is incredibly supportive and keeps the hips fully elevated and aligned with the spine. This makes it one of the best mattresses for stomach sleeping.
We found this side to be a much better fit for back sleeping. Because it’s a touch softer, our hips are able to sink in for just a bit of pressure relief. Some back sleepers might prefer even more pressure relief, but this could be a good match for back sleepers who like a firm feel.
As with the extra-firm side, the firm side is much too firm for side sleeping. We simply didn’t obtain anywhere near enough pressure relief around the shoulder and hip. Side sleepers will definitely want to seek out a dedicated mattress for side sleeping.
The firm side is a great match for stomach sleeping. It’s supportive and helps maintain proper spinal alignment. This means it could be one of the best mattresses for back pain relief.
What Does The Brooklyn Bedding Plank Firm Feel Like?
Both sides of the Plank Firm have a firm, foam feel with some good bounce. You won’t sink into this mattress, so it’s very easy to move around and switch positions. You’ll feel like you’re sleeping on top of this bed instead of “in” it.
Average Weight Sleepers – 130lbs – 230lbs
Average-weight back sleepers who like a firm mattress should enjoy the firm side of the Plank Firm, while the extra-firm side will probably be too firm for this position. Side sleepers will not obtain adequate pressure relief from either side of this mattress. Average-weight stomach sleepers will enjoy plenty of support from either side.
Heavyweight Sleepers – Over 230lbs
Heavyweight back sleepers who like a firm feel could enjoy the firm side of the Plank Firm, while the extra-firm side will almost certainly feel too firm. Heavyweight side sleepers will experience too much pressure around the shoulder and hip on both sides. Both sides of this mattress should be a supportive match for heavyweight stomach sleepers. If you need something even more supportive, check out the best mattresses for heavy people.
Lightweight Sleepers – Under 130lbs
Lightweight back sleepers who like a very firm feel might enjoy the firm side of this mattress, but it’s likely that most lightweight back sleepers will want a mattress that’s a touch less firm. Both sides of this mattress are decidedly too firm for lightweight side sleepers. Lightweight stomach sleepers who like an extra-firm mattress might like the firm side, but in general lightweight sleepers will probably want to look for a bed that’s not quite so firm.
Brooklyn Bedding Plank Firm Mattress Construction
Now that you know what it feels like to sleep on top of one of the firmest mattresses around, let’s take a peek inside of this bed! We’ll review each layer of this bed’s construction and share how different materials influence performance.
The Plank Firm’s “cover” is really its top layer; more on that below. Customers can choose to purchase an optional cooling panel that is sewn onto the surface of both sides of the mattress.
The extra-firm side of the Plank Firm features a comfort layer made from 0.75” of quilted polyfoam, which offers very minimal softness on top of the bed. Next up, there’s a 2” layer of firm TitanFlex foam, a proprietary foam with qualities similar to latex (meaning it’s responsive and bouncy).
On the firm side of the Plank Firm, the top layer consists of 1.5” of quilted polyfoam, which offers a bit more pressure relief than the extra-firm side’s thinner layer of the same material. The foams used in this mattress are CertiPUR-US certified, which means they’re more eco-friendly than conventional foams and they’re low in VOCs (volatile organic compounds).
The Plank Firm’s support layer is made from 7” of a high-density base foam, which lends firm support and structure to the mattress overall. Read our Plank Firm Luxe mattress review if you prefer a mattress with coils.
The Brooklyn Bedding Plank Firm mattress is 11.5” tall.

Brooklyn Bedding Plank Firm Mattress Performance
If you’ve read this far, you know a lot about the Plank Firm mattress. But there are still a few key factors to consider! We put this mattress through a barrage of tests with regard to temperature regulation, motion transfer, edge support, and more. Let’s see how it performed!
Sleeping Hot Or Cold
The Plank Firm is an all-foam mattress, so it’s not the most breathable bed around. However, you can opt to purchase a cooling panel for the surface of both sides of the mattress, which helps prevent overheating. Additionally, because the bed is so firm, you’ll sleep on top of it instead of sinking into it. This allows for air to flow around your entire body, which further prevents sleeping hot.
Because the Plank Firm has a flat, firm surface without much “give,” it doesn’t do a great job of absorbing motion. It’s possible that you could feel the movements of a partner or pet during the night, so keep this in mind if you’re hunting for a mattress for couples.
Even though this is a very supportive mattress overall, the Plank Firm doesn’t feature great edge support. The edge collapsed quite a bit when we sat and laid down near it, and we felt a bit like we might roll off the bed. Neither side features great edge support.
The Plank Firm is made with quality foams and should be fairly durable, although it won’t be as durable as some beds (such as an innerspring mattress with steel coils). You can also flip or rotate the mattress to make it last longer.
Because the Plank Firm uses foams that are CertiPUR-US certified and low in VOCs, it shouldn’t produce unpleasant off-gassing. If you do notice any off-gassing from this mattress, it should dissipate within a couple of days.
We didn’t observe any notable noise from this mattress. Because it’s all-foam, it’s unlikely to grow noisier over time.
The best mattress for sex allows partners to change positions easily. Because the Plank Firm has a very firm, flat, and bouncy surface, it should be a great match. Partners won’t feel stuck in this bed, and it’s easy to move around on top of the mattress.

Brooklyn Bedding Complaints
Not surprisingly, one of the biggest complaints about the Plank Firm is that it doesn’t offer much pressure relief, and as a result side sleepers won’t be satisfied with this mattress. Additionally, some people report that the surface of the Plank Firm feels a bit slippery.
How Does The Brooklyn Bedding Plank Firm Compare To Other Mattresses?
If you’re considering the Plank Firm mattress, then you’re probably interested in other firm mattresses. So let’s do a little comparison shopping! We’ve pitted the Plank Firm against two of its competitors, the Birch and the Big Fig, so you can see how this mattress compares to other beds in its class.
Brooklyn Bedding Plank Firm Vs. Birch Mattress
The Plank Firm is a flippable bed-in-a-box that’s designed to offer a flat sleeping surface and be incredibly firm. Its all-foam construction is made with CertiPUR-US-certified foams and includes a thin comfort layer on both sides, a firm transition layer on the extra-firm side, and a support layer made from high-density base foam. The Birch is a hybrid bed-in-a-box with an eco-friendly construction: It layers an organic cotton cover over wool and Talalay latex comfort layers and a support layer made from individually wrapped coils.
Not surprisingly, both the Plank Firm and the Birch are firm beds. But the Plank Firm is significantly firmer than the Birch. We ranked the Birch around 7/10, while the firm side of the Plank Firm is around 8/10 and the extra-firm side of the Plank Firm is an incredibly firm 9/10.
Even though these beds vary when it comes to construction and firmness, they have fairly similar feels. These are both bouncy, responsive beds that make it easy to move around.
Finally, these beds differ when it comes to price. A Queen-size Plank Firm (sans cooling cover) starts at $999, while the same size Birch costs more at a starting price of $1,299.
Who Should Get The Plank Firm?
- People who want an extra-firm mattress
- Stomach sleepers
Who Should Get The Birch?
- People who want an eco-friendly, organic mattress
- People who want a supportive mattress that balances firmness and pressure relief
- Hot sleepers who need a mattress that sleeps cool

Brooklyn Bedding Plank Firm Vs. Big Fig
As we’ve noted, the Plank Firm is an all-foam bed with a flippable construction. The Big Fig is a hybrid mattress that’s specifically designed for heavier people. It layers a latex foam comfort layer over a polyfoam transition layer and a support layer made from individually wrapped coils.
Even though they have very different constructions, these beds are pretty similar in terms of firmness. We ranked the firm side of the Plank Firm around 8/10 and the extra-firm side around 9/10. Meanwhile, we ranked the Big Fig’s firmness around 8/10. (Note that average-weight sleepers might rank the Big Fig even firmer, because it’s expressly designed for heavier folks.)
These mattresses differ a bit when it comes to feel. The Plank Firm has a bouncy and responsive foam feel, while the Big Fig has a balanced hybrid feel with some bounce.
In terms of price, the Big Fig is significantly more expensive. A Queen-size Plank Firm (without the cooling cover) starts at $999, while the same size Big Fig costs $1,699 at full price.
Who Should Get The Plank Firm?
- Stomach sleepers
- People who like a mattress without much “give”
- People who want a flat sleeping surface
Who Should Get The Big Fig?

- Hot sleepers who want a supportive mattress that sleeps cool
