Brooklyn Bedding Plank Firm Mattress Review (2026) | Expert Tested
The Brooklyn Bedding Plank Firm earned a perfect 10/10 for edge support and a 9/10 for responsiveness in testing, with the high-density foam perimeter holding firm under seated and lying-down edge evaluations and weight drop tests showing immediate surface recovery. Its flippable design (Firm 8/10 on one side, Extra Firm 10/10 on the other), 120-night trial, and all-foam construction make it the strongest pick tested for back and stomach sleepers who want the firmest available feel with the flexibility to choose between two firmness levels on the same mattress. Side sleepers should look elsewhere.
Every mattress featured on Sleep Junkie is evaluated using the same testing framework for support, pressure relief, cooling, motion isolation, edge support, responsiveness, and overall value. Learn How We Test Mattresses.
Testing Scores
Response Time: 9/10
Motion Isolation: 8/10
Edge Support: 10/10
Cooling: 8/10
Value: 9/10
Overall: 9/10
Pros:
– Scored 10/10 for edge support in testing; the reviewer described the edges remaining firm and stable under full seated pressure at the very perimeter, with no sensation of slipping or instability when lying near the edge. She attributed this to the high-density foam construction maintaining its shape even under concentrated edge pressure.
– Scored 9/10 for responsiveness in testing; 10-pound weight drop tests showed immediate surface recovery, and the reviewer described never feeling restricted or stuck during position changes or while lying down. She noted this is notably responsive for an all-foam mattress.
– Flippable design confirmed to produce a meaningful firmness difference in testing; the reviewer described the two sides as distinct enough to matter in practice, with the firm side (8/10) providing a less punishing surface than the extra firm (10/10), making the mattress effectively two products in one.
– Scored 8/10 for cooling with the standard cover; the reviewer did not experience overheating during testing and described the cover as breathable, noting the optional GlacioTex cover upgrade would likely earn a higher cooling score based on her experience with it on the Aurora Luxe.
– Back and stomach sleeping were well-suited to both firmness levels in testing; the reviewer found both sides kept hips elevated and spine in a neutral position, which is the primary alignment check she runs for these positions.
Cons:
– Side sleeping was flagged as a limitation on both sides; the reviewer described the mattress as too firm for her as a side sleeper, with insufficient cushioning at the shoulder and hip contact zones even on the firm (8/10) side. She explicitly would not recommend this mattress to dedicated side sleepers.
– Motion isolation scored 8/10 rather than higher; the weight moved slightly during tossing and turning on the opposite side, and the reviewer noted this is an expected tradeoff for a firmer foam surface where less softness is available to absorb movement.
– At 10.25 inches, the Plank Firm has a lower profile than many alternatives; shoppers who need a taller bed height or prefer the feel of more layers will find this thinner than premium hybrid and luxury foam alternatives.
Why We Picked It
The Brooklyn Bedding Plank Firm earned a perfect 10/10 for edge support and a 9/10 for responsiveness in testing, with the high-density foam perimeter holding firmly under full edge-seated pressure and weight drop tests confirming immediate recovery on both the firm and extra firm sides. Its flippable design gives back and stomach sleepers two meaningfully different firmness options on a single mattress, a feature the reviewer confirmed produces a noticeable feel difference rather than a marginal one. It is the top pick for back and stomach sleepers who want the firmest available surface and the option to choose between firm and extra firm without purchasing a second mattress. Side sleepers should not consider this model.
How the Mattress Feels
The Brooklyn Bedding Plank Firm is a flippable mattress with a Firm side (8/10) and an Extra Firm side (10/10), which the reviewer described as one of the firmest mattresses she has ever tested. The surface provides little to no contouring or body hug; it is flat and unyielding by design, with the slight cushioning on the firm side being just enough to make the surface tolerable for most back and stomach sleepers. The reviewer found both sides unsuitable for side sleeping due to the firmness concentration at the shoulder and hip, and specifically recommended this mattress only for those who already know they prefer an extra firm or very firm surface.
What It’s Made Of
The Brooklyn Bedding Plank Firm is a 10.25-inch flippable all-foam mattress. From center outward on the firm side: a 6-inch high-density base foam core sits between a 3/4-inch quilted extra firm top layer on one side and a 2-inch Supreme Response Comfort Foam layer with quilted cover on the other, giving each side its distinct firmness. No coils or latex are used. An optional GlacioTex cooling cover upgrade is available; the standard cover was tested in this review. All materials are USA-made, backed by a 10-year warranty.
Disclosure by Kristina Hindes: The Brooklyn Bedding Plank Firm Mattress was provided to me free of charge for the purpose of this review. However, all opinions expressed in this article are my own and based on my personal experience with the mattress.
Kristina Hindes is a certified sleep science coach through the Spencer Institute and a licensed clinical social worker. For the Brooklyn Bedding Plank Firm, she evaluated the flippable mattress on both the firm (8/10) and extra firm (10/10) sides across back, stomach, side, and combination sleeping positions. She ran standardized weight drop tests for responsiveness and motion isolation, and tested edge support through seated and lying-down perimeter evaluations.
She was specifically focused on whether the two sides felt meaningfully different in practice and whether the all-foam construction would produce the edge stability and cooling performance she typically associates with hybrid designs.
You can see Kristina’s thoughts in her video above or keep reading on for her review!
I tested the Brooklyn Bedding Plank Firm specifically as an extra-firm mattress, so I focused on whether it kept my hips lifted in back and stomach sleeping, how punishing the surface felt for side sleeping, and whether the flippable design offered a meaningful difference between sides.
I paid close attention to whether the extra firm side felt uncomfortably punishing or whether it maintained a flat, supportive surface through overnight testing. I also confirmed the flippable construction during my physical inspection, checking that both sides’ layer configurations matched the described spec.
In the following sections, I’ll share my honest assessment of the Brooklyn Bedding Plank Firm Mattress, including its strengths, potential drawbacks, and suitability for different types of sleepers. Whether you’re a back, stomach, or side sleeper who prefers a firm sleeping surface, my goal is to provide you with the information you need to determine if this mattress is the right fit for your unique sleep needs.
- With its flippable design, sleepers can choose between an 8 out of 10 firmness on one side and a 10 out of 10 firmness on the other, catering to individual preferences and needs.
- Throughout testing, the Plank Firm performed well in responsiveness (9/10), edge support (10/10), and cooling (8/10 with the standard cover). The construction felt stable and firm across the surface, but long-term durability should still be judged against owner feedback and the 10-year warranty.
- While the Plank Firm Mattress may not be suitable for all sleepers, particularly side sleepers or those who prefer a softer feel, it offers a 120-night sleep trial and a 10-year warranty. This allows customers to purchase with confidence, knowing they have ample time to test the mattress and ensure it meets their needs and preferences.
Our Review Process: Each mattress we review undergoes a rigorous evaluation process. We assess comfort, support, cooling, and durability through both subjective experiences and objective tests.
Criteria include pressure relief, spine alignment, mattress responsiveness, motion transfer, edge support, and temperature regulation. This comprehensive approach ensures our reviews are thorough and unbiased.
I. Mattress Layers, Materials and Construction
The Brooklyn Bedding Plank Firm Mattress is a flippable mattress, so I’ll start by describing the layers from the bottom up.
First Layer
The bottom layer, which can also be used as the top depending on your firmness preference, has a quilted cover.
Moving slightly up by looking underneath the cover, there is a 2-inch layer of Supreme Response Comfort Foam, which provides a slightly less firm feel when the mattress is flipped to this side.
Second Layer
Next, there is a 6-inch layer of high-density base foam, which is Brooklyn Bedding’s firmest support foam. This layer offers deep compression support, ensuring a stable and supportive foundation for the mattress.
Third Layer
The top layer (or bottom, depending on your perspective) features a 3/4-inch quilted top with continuous patterned stitching to maintain the extra firm sleep surface.
It’s worth noting that the Plank Firm Mattress comes with an optional GlacioTex cooling cover, which can provide additional cooling properties. However, the version I tested had the standard cover.
II. Sleep Position
During my personal testing, I found that the Plank Firm Mattress is best suited for back and stomach sleepers due to its high level of firmness. On a scale of 1-10, the mattress ranks as an 8 or 10 depending on which side you sleep on, making it one of the firmest mattresses I’ve ever tested.
As a side sleeper, I found the mattress to be too firm for my liking, which was expected given its design. However, even though the mattress is firm, it still provided just enough cushion to potentially appeal to some side sleepers who prefer a very firm surface.
For combination sleepers who change positions throughout the night, the Plank Firm Mattress responds quickly to movements, ensuring that you don’t feel stuck or restricted. The mattress performed well in all three positions during my testing, allowing for easy position changes without compromising support.
III. Mattress Responsiveness
Responsiveness refers to how quickly a mattress surface returns to its original shape after pressure is applied and released. For an all-foam mattress at this firmness level, I was specifically watching whether the dense foam would recover quickly or hold an indentation, since very firm foam can sometimes be slow to reset.
During my testing, I used 10-pound weights to assess the responsiveness of the Plank Firm Mattress. The weights quickly bounced back after sinking into the mattress, demonstrating excellent responsiveness.
I gave the mattress a 9 out of 10 for responsiveness based on my personal experience, as I never felt restricted or stuck while lying down or moving across the bed.
IV. Mattress Motion Isolation
Motion isolation determines how much movement on one side of a shared mattress transfers to the other. I placed a 10-pound weight on one side and observed how much it moved during vigorous activity on the other side. For a firm all-foam mattress, I expected less cushioning to absorb motion compared with softer foam alternatives, which is reflected in the 8/10 result.
To test the motion isolation of the Plank Firm Mattress, I placed a 10-pound weight on one side of the mattress and observed its movement while I tossed and turned on the other side. The weight moved slightly, indicating that the mattress does transfer some motion. Based on my testing, I gave the Plank Firm Mattress an 8 out of 10 for motion isolation, which is still a good score considering its firmness level.
The all-foam construction of the Plank Firm Mattress contributes to its motion isolation properties, as foam tends to absorb movement better than other materials like innersprings. However, due to the mattress’s extra firmness, there is less plush cushioning to absorb movement compared to softer foam mattresses.
If perfect 10-out-of-10 motion isolation is what you want in your a mattress for couples, I would suggest one of the following models that I’ve awarded top marks to:
V. Mattress Edge Support
Edge support determines how stable the mattress feels at the perimeter when seated or lying close to the edge. I tested the Plank Firm by sitting at multiple points along the full perimeter and by lying near the edge in each sleeping position, specifically curious whether the high-density foam construction would hold up better at the edge than softer foam alternatives I have tested.
To assess the edge support of the Plank Firm Mattress, I sat on the edge and lay near the side of the bed to gauge how supported I felt. The mattress performed exceptionally well in this category, with the edges remaining firm and stable.
I didn’t experience any sense of slipping or falling off the bed, even when sitting right on the edge. Based on my testing, I gave the Plank Firm Mattress a perfect 10 out of 10 for edge support.
The impressive edge support can be attributed to the mattress’s high-density foams, which maintain their shape and firmness even under pressure. This level of edge support is particularly beneficial for those who frequently sit on the edge of the bed, need a caregiver’s help, or sleep close to the sides.
VI. Cooling and Breathability
I evaluated cooling on the Plank Firm using the standard cover version, monitoring whether the dense foam construction would trap heat through extended overnight contact.
While the standard cover is not necessarily cool to the touch, it is highly breathable and well-ventilated. The open-cell technology used in the foam layers helps wick away excess body heat, promoting a neutral temperature throughout the night. I personally did not experience any overheating issues while testing the mattress.
It’s important to note that Brooklyn Bedding offers an optional GlacioTex cooling cover upgrade, which provides enhanced cooling properties. I have previously tested this cover on the Brooklyn Bedding Aurora Luxe and found it to be exceptionally cool, giving it a perfect 10 out of 10 for cooling and breathability.
Other cooling mattresses that achieved a perfect score in cooling include:
VII. Durability and Longevity
The Plank Firm Mattress comes with a 10-year warranty from Brooklyn Bedding, demonstrating their confidence in the product’s durability. The warranty covers sagging and indentations, giving buyers peace of mind when it comes to the mattress’s long-term performance.
During my examination of the mattress, I noticed that it is well-constructed with high-quality materials. The stitching is robust, and the foams used are dense and durable.
I cannot confirm long-term durability from a review period. What I can assess is construction quality at the time of testing: the stitching was robust and consistent, and the foam layers felt dense and well-bonded with no gaps or soft spots. The 10-year warranty is Brooklyn Bedding’s long-term durability commitment, and memory foam mattresses tend to last 7-10 years. This is a general industry range rather than a guarantee for this specific model.
VIII. Potential Drawbacks
While the Plank Firm Mattress excels in many areas, there are a few potential drawbacks to consider:.
Firmness
The mattress is designed to be very firm, which may not be suitable for those who prefer a softer or more plush sleeping surface. Even the “less firm” side of the mattress is likely to be too firm for side and some combo sleepers.
Height
At 10.25 inches tall, the Plank Firm Mattress may be considered relatively thin compared to other mattresses on the market. Some sleepers might prefer a taller mattress for aesthetic reasons or to make getting in and out of bed easier.
All-Foam Construction
While the all-foam design contributes to the mattress’s motion isolation and pressure relief, it may not be ideal for those who prefer the bounce and responsiveness of innerspring or hybrid mattresses.
Instead, I would recommend the upgraded Plank Firm Luxe, which has pocketed coils, or a model from another brand like the Helix Dawn Luxe.
Price
The Plank Firm Mattress is competitively priced for its category, but some shoppers may still find it more expensive than their budget allows, especially for larger sizes like king and California king.
IX. Trial Period, Warranty, Pricing, and Sizes
When choosing a new mattress, know its trial period, warranty, pricing, and sizes. These details matter for a confident investment in quality sleep.
Mattress Sleep Trial
The Plank Firm Mattress comes with a 120-night sleep trial, allowing buyers to test the mattress in the comfort of their own home for about four months. If unsatisfied, customers can return the mattress for a full refund within this period.
This generous sleep trial demonstrates Brooklyn Bedding’s confidence in their product and gives buyers peace of mind when making a significant purchase.

In addition to the sleep trial, the mattress is backed by a 10-year warranty, which covers defects in materials and workmanship. This warranty is on par with mattress industry standards and provides long-term protection for your investment.

I doubt I’ll ever use the softer side.” This review suggests that the mattress’s firmest side is suitable for both back and side sleepers and has helped alleviate back pain.
However, not all reviews were glowing. Edgar F. gave the mattress a 4-star rating, noting, “They take a while to be made and shipped. The mattresses are pretty good but I notice they still sag at heaviest body weight positions. We’ll see as time goes on. Like the fact they can be flipped.”
While this review praises the mattress’s flippable design, it also expresses concerns about sagging and the time it takes for the mattress to arrive.
Mustafa R. awarded the mattress 3 stars, stating, “Not as firm as expected; my back pain is still not relieved with this mattress.”
Jessie J. also gave the mattress a 3-star rating, echoing a similar sentiment of, “Definitely not sure I love it. Back is testy some mornings. Hoping that does not continue.” These reviews indicates that the mattress may not provide consistent comfort and support for all users.
Overall, the customer reviews suggest that the Plank Mattress is an excellent choice for those who prefer a very firm sleeping surface, with many users praising its comfort, support, and durability.
However, as with any mattress, individual preferences and experiences may vary, highlighting the importance of the sleep trial period when making a decision.
XI. Environmental Impact
Brooklyn Bedding takes pride in their commitment to environmental responsibility. The foams used in the Plank Firm Mattress are CertiPUR-US certified, meaning they are free from harmful substances like heavy metals, formaldehyde, and ozone-depleting chemicals. This certification ensures that the mattress is safe for both humans and the environment.
As a bed-in-a-box mattress, the Plank Firm Mattress is shipped compressed, which allows for more efficient transportation and reduces the overall carbon footprint associated with delivery. By compressing the mattress, more units can be shipped in a single vehicle, minimizing the environmental impact of transportation.
Brooklyn Bedding also emphasizes energy efficiency in their manufacturing processes. Their recently constructed factory, completed in 2022, incorporates various green elements, such as temperature-controlled heating and air conditioning, roof skylights, automatic light sensors, and LED lighting. These measures demonstrate the company’s commitment to reducing its environmental impact during production.
XII. Mattress Care and Maintenance
To ensure the longevity and performance of your Plank Firm Mattress, it’s essential to follow proper care and maintenance guidelines:
- Use a supportive bed frame: A sturdy, high-quality bed frame with minimal flex will provide the best support for your mattress and help maintain its shape over time.
- Invest in a mattress protector: A waterproof mattress protector will shield your mattress from spills, stains, and dust mites, keeping it clean and fresh for longer.
- Spot clean as needed: If spills or stains occur, spot clean the affected area as soon as possible using mild soap and water. Be sure to let the mattress dry completely before replacing the bedding.
- Vacuum regularly: To remove dust, dirt, and debris, vacuum the mattress surface every few months using the upholstery attachment of your vacuum cleaner.
- Rotate the mattress: To ensure even wear and prevent sagging, rotate your Plank Firm Mattress 180 degrees every 3-6 months. This will help extend the mattress’s lifespan and maintain its supportive properties.
- Use fresh bedding: Regularly wash your sheets, pillowcases, and other bedding items to keep your sleep environment hygienic and free from allergens and bacteria.

XIV. Frequently Asked Questions
Is the Plank Firm Mattress suitable for side sleepers?
While the Plank Firm Mattress is designed to be one of the firmest mattresses available, some side sleepers who prefer a very firm surface may find it comfortable. However, most side sleepers will likely find the mattress too firm, as it may not provide sufficient pressure relief for the hips and shoulders.
If you’re a side sleeper, it’s best to consider a mattress with a bit more cushioning to ensure proper spinal alignment and comfort.
Can I use a box spring with the Plank Mattress?
Yes, you can use a box spring with the Plank Firm Mattress as long as it provides a flat, supportive surface. However, Brooklyn Bedding recommends using a platform bed, slatted foundation, or adjustable base for optimal support and longevity. If you choose to use a slatted foundation, make sure the slats are no more than 4 inches apart to prevent sagging.
Does the Plank Firm Mattress come with a sleep trial?
Yes, the Plank Firm Mattress comes with a 120-night sleep trial. This means you can test the mattress in the comfort of your own home for about four months. If you’re not satisfied with the mattress during this period, you can return it for a full refund, giving you peace of mind when making your purchase.
How long does it take for the Plank to expand after unboxing?
The Plank Firm Mattress expands quickly after unboxing and is ready for immediate use. During my personal testing, I noticed that the mattress reached its full size and shape within a few minutes of removing it from the packaging.
However, it’s recommended to allow the mattress to air out for a few hours before using it, as there may be a slight off-gassing odor initially.
Is the Plank available in different firmness levels?
Yes, the Plank Firm Mattress is a flippable mattress, offering two different firmness levels in one. One side is rated as an 8 out of 10 on the firmness scale, while the other side is a 10 out of 10, making it one of the firmest mattresses available. This dual-sided design allows you to choose the firmness level that best suits your preferences and sleeping style.
How does the Plank compare to other firm mattresses?
The Plank Firm Mattress is one of the firmest mattresses available, with one side ranking as a 10 out of 10 on the firmness scale. Compared to other firm mattresses I’ve tested, the Plank Firm Mattress stands out for its exceptional firmness and support. It offers a stable, flat surface that caters to sleepers who prefer a very firm feel.
While other firm mattresses may provide similar benefits, the Plank Firm Mattress’s flippable design and ultra-firm option set it apart from the competition.
How do I clean my Plank Mattress?
To clean your Plank Firm Mattress, start by removing the bedding and vacuuming the surface using the upholstery attachment of your vacuum cleaner. This will help remove dust, dirt, and debris.
If there are any spills or stains, spot clean the affected area using mild soap and water, being careful not to saturate the mattress. Allow the mattress to dry completely before replacing the bedding. For added protection, consider using a waterproof mattress protector to keep your mattress clean and fresh.
