We think that Plank mattresses offer firm construction and strong edge support, making them a great choice for older adults.
A queen Plank mattress costs $1,332–$1,598.
Plank is one of the firmest mattresses we’ve tested, with a firm side and an extra firm side that users can flip between.
We recommend Plank for older adults, higher-weight sleepers, and people with mobility issues who want extra stability and support.
Despite its memory foam construction, the Plank was still easy for our testers to move around on.

NCOA supports everyone’s right to age well. So we take the time to research, test, and recommend products that can help you live a healthier life. We’ve spent more than 2,500 hours researching and testing mattresses to give you the most accurate product reviews. To find the best mattresses, we:

Consulted with sleep specialists like doctors, occupational therapists, and physical therapists for guidance on choosing the best mattress
Put more than 130 models through a series of 19 different tests at our in-house lab
Mystery-shopped more than 40 brands
Surveyed more than 2,000 older adults on their sleep quality
Interviewed experts on the importance of good sleep for older adults
Worked with older adult testers to evaluate mattresses and get their opinion
Read thousands of verified customer reviews

We’re constantly testing new mattresses and sleep products to give you the most accurate and up-to-date recommendations. Read more about our mattress review methodology.

Plank earned best overall in our best firm mattresses guide because it has the highest firmness level of all mattresses we’ve tested. Medium-firm mattresses have long been considered helpful for a good night’s sleep.¹ But people with mobility issues or who need extra spinal support tend to benefit more from a firm mattress. With both a firm and an extra firm side, Plank’s mattress offers stability and structure that we believe can benefit older adults as they sleep.

Plank is owned by Brooklyn Bedding, which means there might be some overlap between the two brands’ offerings, but we focus on what sets Plank apart from other mattresses on the market.

In this Plank mattress review, we highlight what makes this brand unique, who might benefit from a firm mattress, and what to consider before choosing a mattress.

Why choose Plank?

Plank offers a very firm mattress for people looking for extra stability and support. The majority of the mattresses we’ve tested fall into the medium-firm range, which is about a 6.5 out of 10 on our scale. Plank’s firm side rates as an 8 out of 10, and its extra firm side rates as a 9 out of 10.

For people with mobility issues, a firm mattress can make it easier to shift positions during the night. And firm mattresses are recommended for higher-weight people because they create less sinkage.

We are especially impressed that Plank is able to achieve this firmness using only memory foam. Memory foam typically causes a sleeper to sink into the mattress, which makes it difficult to flip over easily. Our testers reported it was not difficult for them to move into different sleeping positions on the Plank.

A woman lies on her side on a mattress — Testers said it wasn’t difficult for them to move from one position to another on the Plank.

We also like how stable the edges are on the Plank mattress. Edge support is important for people who need to use their hands to push themselves to stand. An unstable edge, or one that sinks deeply when you sit on it, increases the chances of sliding off the bed or falling. That’s important because one-fourth of older adult falls happen at night.² And of those nighttime falls, more than half were due to leaving bed to visit the bathroom, according to research.

Sturdy edges also help provide a sense of security while sleeping, so you don’t have to worry about falling off the edge. This means you can use the entire surface of your bed to sleep instead of avoiding getting too close to the edge.

But the Plank mattress’s firmness also means it’s not the best for people who want pain relief. The sturdiness means this mattress doesn’t cushion joints very well. And, if you’re a lighter-weight sleeper, you might find the lack of sinkage uncomfortable. If you're looking for a bed with better pressure relief, consider reviewing our roundup of the best mattresses for back pain.

The Firm: Plank’s Flagship Mattress

The Plank Firm offers a truly firm sleep experience with excellent edge support. The dense memory foam stays cool during the night, and its motion isolation means you’re less likely to be woken up by a partner or a pet.

Our experience with the Plank Firm

When we tested the Plank Firm, we were impressed by how sturdy the memory foam construction was. The majority of mattresses we test fall into a medium-firm range, but Plank’s dense memory foam offers a truly firm sleeping experience. Our testers liked how the mattress had minimal sinkage when they laid down. “I didn't feel much sinkage at all,” said one tester, Patti, a 70-year-old average-weight side sleeper with arthritis who’s fallen out of bed in the past due to weak edges. “[I] feel like [I’m] staying on the top.” This means it’s easier to shift positions versus a traditional memory foam mattress, which has more sinkage and takes more effort to flip from side to side. “Although there is a little cushioning…it was easy to switch from back to side,” Patti said.

A person rolls a large barbell across the surface of a mattress — The Plank showed almost no motion in our seismograph study when we dropped and rolled a large barbell across the opposite side of the mattress.

Another benefit of memory foam is motion isolation. The foam absorbs movement, so if you’re sleeping next to another person or a pet, you’re less likely to feel it when they shift or get out of bed. We rated the Plank Firm a 5/5, meaning it’s a great option for people who are sensitive to other people moving around at night.

Even though memory foam typically traps heat,we found the Plank Firm does an excellent job at staying cool throughout the night.³ Plank also offers a GlacioTex Cooling Cover for $150. “The top feels pretty cold when I first touch it,” Patti said. “One thing about this mattress is I'm definitely sitting ‘on top’ of it, and so the sides aren't coming up to hug me. That makes it feel a little cooler since there's literally less fabric touching me.”

A temperature gun shows a screen that reads 61.8 degrees F — Though memory foam isn’t known for its cooling properties, we were impressed with how cool the Plank stayed through our temperature gun testing.

And we were very impressed by the mattress’s edge support, giving it a 5/5. When our testers tried to stand up from a seated position, they felt supported by the sturdy edge. “[I] didn't feel insecure when standing up,” Patti said. As someone who’s fallen out of bed before due to weak edges, Patti said she felt very secure sitting or lying down near the edge.

This is important for people who might need to use their hands when standing up. It reduces the chance of someone slipping off the edge and falling to the floor.

A woman lying on her side at the edge of a mattress — Testers loved the super strong edges of the Plank. They could lie right on the edge without feeling like they could fall off.

But the firmness of this mattress also has some drawbacks. The lack of cushioning increases pressure, so if you have pain or joint problems this mattress won’t provide much relief. If you want pain relief, the best hybrid mattresses might be a better choice for you. And for lighter-weight sleepers, the lack of sinkage can make you feel like you’re sleeping on top of a board (hence the name of the mattress, the “Plank”).

A woman lies on her side on a pressure map on top of a mattress — The biggest drawback of the Plank is its lack of pressure relief. The mattress didn’t do well in our pressure map testing, showing pressure in key points throughout each tester’s body.

Your mattress should provide the right amount of support and accommodation for your spine, as it will help take stress off sensitive muscles and joints.”

— Jordan Duncan, MD, chiropractor at Silverdale Sport & Spine in Silverdale, Washington

Who is the Plank Firm right for?

The Plank Firm is right for people who enjoy the feeling of sleeping on a truly firm mattress. If you shift around a lot at night or need support from your hands while pushing yourself to stand, this mattress is a great option.

Its motion isolation capabilities also mean it’s good for people who share their bed with a partner or pet.

The Plank Firm Luxe: An extra-firm hybrid mattress

The Plank Firm Luxe is an enhanced hybrid version of the original Plank all-foam mattress. The Luxe version of the Plank adds a sturdy coil layer for extra responsiveness, support, and cooling. While pricier, it offers the benefits of both coils and foam in a more luxurious mattress.

Our experience with the Plank Firm Luxe

We tested the Plank Firm Luxe for edge support, responsiveness, motion isolation, cooling, and pressure relief.

Our testers found the Plank Firm Luxe to be highly responsive and easier to change positions. Like the Plank Firm, this mattress is for people who need extra-firm support. The mattress offers reliable full-surface support from edge to edge.

When assessing the bed’s edge support, the Plank Firm Luxe impressed our testers. “I felt super secure lying near the edge. You can sleep right up to the edge, and really spread out without feeling unstable," said one of our testers. This makes the bed a good option for couples, ensuring both get the same support on the bed’s edges as they do in the center. “I don't need assistance or to use my hands to get in and out of bed. The mattress has immediate responsiveness," added one tester. People with mobility concerns may benefit from the Firm Luxe's strong support when getting in and out of bed.

Despite its extra foam and coil layers, the Plank Firm Luxe also had excellent motion isolation. The bed earned a 4/5, so it may help limit motion transfer between people sharing the bed. This also means if you move around a lot during the night, you’re less likely to wake yourself up.

The extra layer of coils in the Plank Firm Luxe can help keep the mattress cool, offering added airflow. But our testers found its cooling to be only average. “As I was lying there, I felt myself warm up ever so slightly. It's pretty firm, so I didn't feel like I was being hugged by warm, doughy foams. Instead, it was just slightly warmer in the areas my body was lying on,” said one tester.

Like the original Plank, the Plank Firm Luxe had impressive edge support, scoring a 4.5/5. “The mattress has great edge support, and I don't need assistance getting in and out of bed. I don't have to use my hands and the mattress has immediate responsiveness,” said one tester when resting on the bed’s edge. This should stand out to couples because it highlights the bed's sturdy, reliable support.

A woman sitting on the edge of the Plank Firm Luxe mattress — Our testers found the Plank Firm Luxe offered impressive edge support. They scored the bed’s seated edge support a 4.5 out of 5.

The Plank Firm Luxe, like the original Plank, is for people who aren’t concerned with cushioning. Instead, it suits those who want extra-firm support. For example, higher weight sleepers may find strong spinal support. But if you have joint pain, this mattress may not provide enough pressure relief due to its firmness. Our testers felt aligned and supported when lying on their back or stomach. But they found pressure built on their hips and shoulders when lying on their side.

A woman lying on her side on the Plank Firm Luxe mattress — While the Plank Firm Luxe scored well in pressure relief for back and stomach sleepers, it didn’t offer enough cushioning for side sleepers.

Who is the Plank Firm Luxe right for?

The Plank Firm Luxe could be a good fit for people who want a truly firm mattress. If you value sturdy edges and reliable full-surface responsive support, the Plank Firm Luxe may be a good choice.

Its coils mean you can expect increased responsiveness. This feature may work well for people who change sleeping positions throughout the night. The Plank Firm Luxe adapts to movements with consistent support.

I may love it if I:
Sleep with a partner	Yes
Have chronic pain	Yes
Feel hot at night	Maybe
Have mobility concerns	Yes
Sleep in the following positions	Side, back

Who should keep looking for their perfect mattress?

People who like the sinking-in feeling of soft, all-foam beds
Those who tend to overheat when sleeping
People who like to sleep on their sides

Plank mattress price

Plank prices its mattresses competitively, offering a high-quality product for less than some of the other brands we’ve tested, like Saatva, which costs $2,139 for a queen-size. When on sale, Plank’s pricing is comparable to other budget-minded companies like DreamCloud, which also offers sales, lowering the cost to about $1,000 for a queen-sized mattress.

Is a Plank mattress right for you?

Plank mattresses are right for you if you enjoy sleeping on a truly firm mattress. The lack of cushioning and support might make this mattress feel uncomfortable for some people, especially lighter-weight sleepers or those with chronic pain. But it’s a great choice for higher-weight sleepers, people with mobility concerns, or those who just prefer a really firm mattress. We like that you can flip this mattress between a firm and extra-firm side for a more custom sleep experience.

We also think these mattresses are a good fit for people with mobility issues who need extra support while pushing themselves to stand. The sturdy edges offer stability so you don’t sink into the mattress and have to work harder to get up.

And we like that Plank uses memory foam for its construction. In our March 2025 survey, 50% of respondents said they chose a memory foam mattress, making it a popular choice.⁴ This mattress’s motion isolation and cooling technology make it great for both people who sleep with a partner or pet or who get hot at night.

Plank also doesn’t offer white-glove delivery service, meaning you’ll be responsible for moving the mattress to its frame. If you don’t have help, maneuvering a heavy box like this could be dangerous or difficult. If you need assistance in moving the mattress, an option like Saatva (which comes with free white-glove delivery) might be a better choice. You can learn more in our Saatva mattress review.

Before choosing a mattress, ask yourself these questions:

What sleep issues am I hoping to solve with a new mattress?
Do I wake up easily from others’ movements?
Am I a hot sleeper?
Do I prefer the feel of a truly firm mattress or do I like something more supportive?
