What is the Plank Mattress

Inspired by the minimalist approach to sleep in parts of Asia, the all-foam Plank Firm mattress promises a firmer, flatter surface that promotes spinal alignment for better back support and proper posture. The solid surface of the Plank Firm is also engineered to reduce pressure on your circulatory system for better blood flow while promoting more oxygen intake while you sleep. 

But the best part? The Plank Firm is flippable, giving you two unique sleep surfaces to choose from for the price of one. The top side of the mattress is similar to your standard firm feel, while those who prefer an even firmer sleep surface can simply flip and enjoy. 

In addition to the Plank Firm mattress, you can also choose the hybrid Plank Firm Luxe that pairs the flippable features of the original with the added benefits of individually wrapped coils for extra responsiveness and pressure point relief. The line also includes an organic, eco-friendly option known as the Plank Firm Natural.

Plank Firm Mattress: A Closer Look 

Thoughtfully designed to provide one of the firmest sleep experiences on the market with two unique, flippable surfaces, The Plank Firm has even been endorsed by the American Chiropractic Association. A three month study found that this all-foam firm mattress helped to reduce spinal stress, improve lumbar support, and alleviate back pain. 

Materials Used

The Plank mattress is 9.5” tall and is made up of:

  • A six-inch layer of high-density, polyfoam core
  • Two, .75” quilted layers on either side of foam core to ensure minimal loft 
  • Two inches of Titanflex™ comfort foam for deep compression support 
  • Optional GlacioTex cooling cover to help promote airflow and cooling on contact 

The upgraded Plank Firm Luxe Mattress builds on these benefits by adding a six-inch core of individually wrapped TitanCore coils and additional foam layers to increase responsiveness and support that’s perfect for partners. And, if you want the most natural sleep surface, you can’t go wrong with the Plank Firm Natural featuring 100 percent organic cotton, wool and Talalay latex so you can sleep soundly knowing you made a safe, sustainable choice. 

Mattress Type

As previously mentioned, sleep shoppers can currently choose between three unique mattress types: 

  • Plank Firm: Super firm, flippable support 
  • Plank Firm Luxe: Hybrid design featuring extra layers 
  • Plank Firm Natural: Eco-friendly, organic construction   

It’s important to note that the Plank Firm mattress comes in both standard and more custom sizes, including short, olympic and RV styles. 

Ages Suited For

The Plank Firm mattress is suitable for all ages as it provides both comfort and support to sleepers of every body size.

Sleeper Types Suited For

If you prefer to sleep on your back or stomach and like a firmer feel, then the Plank Firm mattress is meant for you. These particular positions benefit from firm spinal support, and the Plank Firm is designed to promote a neutral spine position while helping to prevent your hips or midsection from sinking, which can contribute to back pain. 

While side sleepers who prefer a firmer sleep surface may still like the feel of the Plank Firm, typically they need more contouring than this particular mattress provides to help alleviate pressure points. The Plank Firm Luxe is a better fit for side sleepers as it has additional foam layers and a coil core that contour to the body. 

Firmness Level

As one of the firmest mattresses on the market featuring two levels to choose from with its flippable surfaces, the Plank Firm really caters to customers who prefer to sleep on top of their mattress as opposed to sinking into it. 

According to Brooklyn Bedding who makes the Plank Firm, the firm side measures around an eight on the typical firmness scale of one to 10, while the ultra-firm side falls closer to a 10. Essentially, the only way to get a firmer sleep surface would be to sleep directly on the floor. 

Getting the Plank Mattress

The Plank Firm mattress is a great choice for those who are looking for an extra firm mattress. It’s constructed with two unique firmness levels, so you can pick the one that best suits your needs. But the best part? You can shop, ship and set up your mattress without ever leaving home. 

Plank Firm Mattress Cost & Coupons

Plank firm mattresses start at $749, with the standard Queen sizes costing $1,332 at full retail value.* 

Brooklyn Bedding often runs seasonal promotions that can offer significant savings, as well as a year-round discount of 30 percent off for certain groups including military, first responders, medical providers, educators and students.   

You can also finance your Plank Firm mattress purchase through Affirm to spread out your payments over three, six or 12 months.

*Prices at time of this review; subject to change.

Shipping and Delivery

The Plank Firm mattress is crafted in Phoenix, Ariz., and shipped free of charge via FedEx Ground within the contiguous United States (white glove delivery is not currently available). They can also ship to Hawaii, Alaska and even Canada for an additional fee. 

Delivery typically takes three to seven business days from the time of purchase. The mattress will arrive compressed in a box and can be set up easily in minutes by following the included instructions. While it will typically begin to decompress within the first few minutes, you should really give it a good 24 hours to fully expand and air out before breaking it in.  

Since the Plank Firm can weigh between 60 and 105 pounds, it’s best to have help when transporting to your preferred space, plus unboxing and setting it up.

Plank Firm Mattress Performance

Besides being backed by the American Chiropractic Association (ACA), the Plank Firm mattress is preferred by sleepers who like the firmer support of a solid surface without that sinking feeling. Let’s take a closer look at how it stands up across popular performance features:

Motion Isolation / Transference

The Plank mattress does a great job at isolating motion transfer across the bed. While you may feel a little less tossing and turning from your partner with the Plank Firm Luxe due to the extra layers of foam and coil core (making the Firm Luxe an awesome choice for couples), the Plank Firm still limits movements enough that you could sleep soundly solo or next to that special someone. 

Pressure Relief

The Plank Firm mattress provides lower back relief by promoting a neutral spine alignment, making it better suited to help alleviate the common pressure problems that back and stomach sleepers often encounter. Stick to the firm side (versus ultra-firm) for slightly more responsiveness and pressure relief. 

Temperature Control (Hot vs Cold)

The Plank firm mattress does a great job at regulating temperature throughout the night, and customers who tend to sleep hot can also purchase the optional GlacioTex Cooling Cover for additional cooling comfort on contact. 

If you run hot, you may also want to consider the Plank Firm Luxe, which includes individually wrapped coils for extra air flow, or the Plank Firm Natural, which offers ultra breathability. 

Edge Support

Unlike many all-foam mattresses, the Plank Firm mattress offers good edge support even when you’re sleeping near the edge of the bed, thanks to its extra firm surface. This ensures that you get full use out of your entire sleeping surface without feeling like you’re going to roll off the edge of your bed during the night. 

Ease Of Movement

The Plank Firm mattress’s dual firm surfaces help sleepers to sleep on the bed versus in it (like memory foam). This makes it easy for you to toss, turn or get up from your bed without feeling stuck or uncomfortable.


The Plank Firm mattress is handcrafted in the United States with high-quality, high-density materials that are built to last. The firm and ultra-firm surfaces are designed to resist sagging or indentations over time so you can enjoy consistent comfort throughout its lifespan.


The all-foam construction of the Plank firm mattress means it is virtually silent when bearing weight, so there’s no need to worry about any squeaks or creaks coming from your bed during the night. This makes it perfect for light sleepers or those who live in shared spaces where noise can be disruptive during quiet hours.


The Plank Firm mattress has a firmer surface that allows you to move about easily, but lacks the bounce of traditional coil or hybrid mattresses that couples may prefer. The Plank Firm Luxe or Plank Firm Natural can provide more of the springy feel better suited for intimate moments. 


When first unboxing your new Plank mattress, there may be some initial off-gassing odor due to its all-foam construction, however this should dissipate within a 24 hours to a few days after airing out in a well ventilated room. If you’re particularly concerned about off-gassing, you should consider the Plank Firm Natural, which includes organic and natural latex materials. 

Comparing the Plank Mattress to Other Brands

With so many direct-to-your-doorstep mattress brands to shop, we’re putting the Plank Firm up against a few popular competitors to see what makes it stand out:

Plank Mattress vs. Casper

The Casper mattress is a popular all-foam model that offers a one-side-fits-all, medium-firm feel to suit a variety of sleepers. The Plank Firm offers two levels of comfort in one mattress with flippable firm or ultra-firm sides, which are both firmer than what you’ll find from the Casper. While both companies offer 10 year warranties, the Plank Firm comes with a slightly longer trial period (120 nights versus 100 with the Casper), and is made right here in the United States. And though both companies often run promotional discounts, the Plank Firm is typically priced slightly higher than the Casper. 

Plank Mattress vs. Saatva

Saatva is one of the most known names in the at-home mattress space, and they offer a wide range of mattresses to suit almost any sleepers. Their Loom & Leaf memory foam mattress is comparable to the all-foam Plank Firm from Brooklyn Bedding, but while shoppers have to choose upfront which feel they prefer with the Loom & Leaf mattress (medium firm or firm), the Plank Firm offers two firm feels in one mattress so you can flip between both as needed. Saatva offers one of the longest trials and warranties, but their Loom & Leaf foam mattress comes in at almost twice the retail price of the Plank Firm. 

Plank Mattress vs. Tempurpedic

The Tempur-Pedic® mattress is one of the most well known memory foam mattresses on the market today. It has several layers of adaptive memory foam that provide superior pressure relief and contouring, while its cooling technology helps keep you cool throughout the night. The Plank Firm mattress also features an all-foam, flippable design, but both of its firm and ultra-firm sides offer a firmer feel than the TEMPUR-Cloud®’s medium feel. The Plank Firm also comes with a 120-night trial compared to the 90 nights you get with Tempur-Pedic, and both come with a 10 year warranty. The Plank Firm is also more budget-friendly, coming in a few hundred dollars less than the TEMPUR-Cloud mattress. 

Plank Firm Mattress Made by Brooklyn Bedding

On the forefront of the bed-in-a-box boom since the very beginning, Brooklyn Bedding is a family owned and operated mattress company based in Phoenix, Arizona. Originally founded in 1995 by two brothers, they have remained committed to custom creating mattresses at affordable prices manufactured right here in the U.S. using only the finest materials and modern technologies to deliver sound sleep right to your door.  

Plank Mattress Customer Service

Whether you have a question about shipping, returns, set up or more, support is available by calling 1-623-624-1222, chatting live or submitting a request at  

Trial Period

The Plank Firm line of mattresses comes with a generous risk-free trial period of up to 120 nights, beginning from the date of delivery. That means that if you’re not 100 percent satisfied with your mattress for any reason, you can request a refund (minus any additional shipping fees). Since it can take a little while to break in your new mattress and adjust, the brand requires you to wait at least 30 days from delivery until making any decisions. 

But before you decide that the Plank Firm just isn’t the right fit, Brooklyn Bedding will even offer a free mattress topper to help soften the surface and increase pressure point relief (you’ll need to contact Customer Support to request this). This is a perk you don’t often see, and something that shows the company really cares about customer satisfaction. 


Brooklyn Bedding stands behind their handcrafted mattresses by offering a 10-year warranty beginning on the date the mattress was purchased. The warranty covers manufacturer defects and not normal wear and tear. 

Our Verdict

The Plank Firm mattress is specifically designed for people who prefer a firmer sleep surface. With its unique flippable design, you’re essentially getting to experience the feel of two mattresses for the price of one, and we think back and stomach sleepers can especially benefit from the extra firm support that can help reduce back pain and improve posture. Its affordable price, 120-night trial and 10-year warranty make it a safe bet for anyone in the market for an extra-firm bed.  


Are Plank mattresses any good?

Plank mattresses are highly rated for their unique firmness levels and flippable design, and are even endorsed by the American Chiropractic Association (ACA). The Plank Firm mattress is a dual-sided, all-foam mattress designed for those who find the typical firm bed too soft. It offers a firm (eight out of 10) and ultra-firm (10 out of 10) side, making it great for both back sleepers and stomach sleepers. Reviews of the Plank mattress have been overwhelmingly positive, with many customers praising its durability and support. With its two unique firmness levels, the Plank Firm mattress is an excellent choice for those looking for a comfortable yet firmly supportive sleeping experience.

Where can I try the Plank mattress?

If you prefer to shop in person, you may be able to test out the Plank Firm mattress at select Brooklyn Bedding stores or preferred retailers. You can also find it at select online retail partners, such as Amazon. They offer a 120-night trial period, so you can get your money back if it’s not the bed for you. It’s always smart to read reviews before making a purchase to help decide it’s the right mattress for you.

Where can I buy the Plank mattress?

Which side of the Plank mattress is harder?

The Plank Firm mattress by Brooklyn Bedding is a dual-sided all-foam mattress with two firmness levels. On a scale from one to 10, the firmer side of the Plank mattress comes in around 7.5-9 on the firmness scale, while the ultra-firm side is rated at 9.5-10.5 on the firmness scale. The ultra-firm side is one of the firmest, flattest sleep surfaces on the market.
