If every mattress feels too soft to you, the Plank Firm may be the solution. This all-foam bed by Brooklyn Bedding is one of the firmest mattresses you can find. Furthermore, you can use either side of it by flipping it over (so it’s technically two beds in one).
One side is super firm, and the other is even firmer. The mattress is also quite affordable, especially considering it’s designed specifically for people with a firmness preference well above the average. In this article, I’ll help you learn everything about the Plank and whether it’s the firm mattress you’ve been missing.
As a certified wellness coach, I know the true value of rest and the need for a proper bed to achieve restorative sleep. Working with Mattress Clarity has helped me guide many people to better sleep health. In the past seven years, Mattress Clarity has tested over 500 mattresses and 150 sleep products.
We have helped over 40,000 people find the right bed for their home. We also receive guidance from our chief medical advisor, Dr. Raj Dasgupta, and gather hands-on feedback from Dr. Hannah Habeeb, Mattress Clarity’s chief medical product tester. Our testing considers every sleeper’s needs and all sleeping styles to deliver unbiased reviews based on thorough testing by our sleep specialists.
Now, with all that said, let me walk you through the Plank!
Our Plank Firm Review in a Nutshell
The Plank Firm is a flippable all-foam mattress. Each side offers a different firmness option, offering versatility. It is an excellent choice for those who want a firm surface. However, this bed is not for fans of memory foam mattresses, so you shouldn’t expect that cradling, cushiony feel. We found that the Plank works well for heavier sleepers in need of a supportive mattress. Couples and combination sleepers will revel in the bed’s responsiveness. Hot sleepers will want to add the Plank’s Glaciotex cooling cover ($150 add-on fee) for a more comfortable night’s rest.
The Plank Firm offers a solution for people who always find their mattress too soft and not supportive enough. The bed’s dual-sided use essentially offers two beds in one, giving you more bang for your buck. Additionally, it is quite affordable considering its quality. I’d suggest the Plank for heavier sleepers, combination sleepers, and couples. But, only if they truly want a bed that doesn’t mess around when it comes to firmness.
Plank Firm Mattress Performance: My Overall Rating
Our testing methodology assesses mattresses across a variety of performance categories to create an overall score and help you know whether it works well for what’s important to you. We put the Plank Firm to the test in our studio and gave the firm side 3.9/5 overall, while the extra-firm side earned 4.2/5. Averaging those scores gave us a score of 4.1/5 for the bed as a whole. We found the mattress had great edge support and supreme responsiveness, and, as the name suggests, it offered very firm yet generous support.
I’ll go through everything our testers found in each category. But just to know, you can easily hover your cursor over the icons below for a quick definition of what each score means.
Watch Us Test the Plank Firm Mattress
I Recommend the Plank Firm For…
- Heavier and stomach sleepers. The Plank’s firmness options should provide high-quality support for both heavy and stomach sleepers.
- Shoppers on a budget. The Plank is fairly affordable given its versatility and unique firmness levels.
- Combination sleepers and couples. The mattress has excellent responsiveness, making it really easy to move around on the bed and switch sleeping positions.
I Don’t Recommend the Plank Firm For…
- Lightweight side sleepers. The Plank may make you feel like your joints are sleeping on marble because it’s so firm.
- Pressure-relief seekers. Many sleepers, especially those with joint or back pain, may not find the pressure relief they need on the Plank.
- People who want cushioning. For some, the Plank may offer just the right firm feel they need, but if you expect the sort of cushioning comfort of memory foam, this bed is not for you.

How Firm is the Plank Firm Mattress?
The Plank Firm offers different firmness on each side, making it a flippable dual-sided mattress. Our firmness guide ranges from 1 to 10, with 1 being as soft as it gets and 10 being like a hardwood floor. For comparison, the industry-standard is 6.5/10 firmness on our firmness scale. Our testers determined that the Plank has an 8/10 firmness on one side and 9/10 on the other.
The Plank Firm is one of the firmest mattresses available today (on both sides).
How Does the Plank Firm Feel for Different Body Types and Sleeping Positions?
According to Dr. Dasgupta, your preferred sleeping position is a major factor in which mattress works best for you. “Side sleepers typically need softer beds that cushion their shoulders and hips, but back and stomach sleepers may find that they enjoy the spinal alignment offered with a firmer mattress,” he said.
The Plank is one of the firmest mattresses you can get today. Its 8/10 and 9/10 firmness options offer far firmer support than most beds, making the Plank a go-to for people who want a seriously firm bed.
However, although there will be exceptions, I’d say most light and average-weight sleepers (especially those who prefer sleeping on their sides) will find the Plank too firm for comfort. Overall, I would suggest this bed for heavier sleepers, some average-weight sleepers, and most stomach sleepers.
I arranged a table below that outlines what different sleeper types in different weight categories can expect with the Plank Firm.
| Sleeper Weight | Side Sleepers | Back Sleepers | Stomach Sleepers |
| Light (under 130 lbs) | Unpleasant | Good | Good |
| Average (130-230 lbs) | Unpleasant | Good | Good |
| Heavy (over 230 lbs) | Good | Excellent | Excellent |
Lightweight Tester 5’5”, 128lbs
“On my back, the mattress feels slightly more forgiving than on my side, but still very firm. I feel pressure against my lower back and shoulders, but everything is fairly elevated.” – Caitlin Giddings
Average-weight Tester 5’6”, 160lbs
“The firmness kept my hips from sinking when I was on my stomach, so I felt very aligned.” – Melanie Kassel
Heavyweight Tester – 6’4”, 250lbs
“It’s firm, but that doesn’t mean it’s not pressure-relieving. I’m surprised that I like it a bit, from a pressure-relief standpoint.” – In-house tester
Plank Firm In-Depth Test Results
Pressure Relief
Despite being an all-foam mattress, the Plank was so firm that it didn’t provide our testers with the cushiony pressure relief many seek from foam-based beds. This was reflected in our testers’ pressure relief scores: the Plank received a 2.7/5 on its firm side and a 3/5 on its extra-firm side.
These scores reflect our testers’ subjective, hands-on experiences and an objective test using a specialized mat that measures pressure in pounds per square inch (PSI) and provides color-coded images that map the pressure testers in different weight categories feel.
For reference, we consider a side-sleeper PSI around 14.58 to be typical, and a PSI around 12.43 for back sleepers. Lower-than-typical PSI readings imply better pressure relief, while higher-than-typical PSI readings imply worse pressure relief.
Firm Side Pressure Relief
Our lightweight tester tried the Plank on their side and was disappointed, giving it a 2/5 rating. However, I want to note this may have been specific to their experience, as their 12.54 PSI reading indicated decent pressure relief. Regardless, they described side-sleeping on the Plank, saying, “I don’t like this at all. It’s just too firm, and it feels like it’s digging into my hip.”
Then they switched to their back, and said, “On my back, the mattress is definitely more comfortable.” While they felt better on their back, the lack of cushioning earned the Plank a 3/5 for back sleeping.
Our average-weight tester gave the Plank a 2/5 for side and back sleeping. The low grade wasn’t surprising, considering how they described the experience, “I feel pressure throughout my entire body. This mattress is way too firm for me, particularly in my shoulders and hips.”
Although the pressure maps showed better-than-average pressure per square inch in both sleeping positions (13.37 PSI for side and 11.26 for back), the tester claimed that she felt a lot of pressure in their shoulders and lower back. “I just don’t love it,” they said.
The Plank performed best for heavyweight back sleepers. Although their PSI of 14.08 was slightly higher than the average reading (12.43), the tester gave it a 4/5 in this position. They said, “I feel this is a much better fit for heavy back sleepers.”
Extra-Firm Side Pressure Relief
When we flipped the mattress to the extra-firm side, the lightweight tester’s PSI readings were 11.96 for side sleeping 10.79 for back. The tester gave both positions a 3/5 rating. Although they didn’t find the bed particularly comfortable, they acknowledged that they felt supported and weren’t experiencing a ton of pressure.
Product expert and average-weight sleeper Nicole Davis preferred this mattress for back sleeping. “I don’t sleep on my back, but this bed is considerably more comfortable on my back than my side.” This was reflected in her pressure relief scores. She gave the Plank Firm a 2/5 for side sleeping, while back sleeping earned 4 stars.
Our heavyweight tester was also less than impressed with the Plank’s pressure-relieving abilities when he was on his side. He gave it a 2.5/5, saying, “Yeah, I am not a fan. I like how supportive it is, but it’s just not very comfortable. It doesn’t give at all, and it’s jamming my shoulder into my head.” His sentiments were understandable given his well-above-average PSI reading (18.33).
However, he gave it 4.5/5 on his back. “This is way better on my back. Very supportive. Keeps everything aligned without much pressure. I could do with a little more cushion, but overall I like it.”
Dr. Hannah Habeeb, our chief medical product tester, also tried out this bed in our mattress studio. She appreciated the support and how well it kept her spine aligned. However, she cautioned that its lack of cushioning could cause pressure buildup for many sleepers. She also said that those with joint pain may want to look for an alternative, as both sides would likely be too firm.
Edge Support
I define quality edge support as how durable a bed’s perimeter is when supporting someone resting on its edges, while also preventing sagging when someone gets in and out of the bed. Edge support can also reflect how durable your bed will be in the long term. Moreover, if you lounge at the edge of your bed, share it, or need firm edges to get in and out, edge support will be important to you.
We tested both sides of the Plank for edge support and rated the firm side 3.8/5 and the extra-firm side 4.8/5.
We did two tests to get these scores with the Plank. The first one is a feel test, where a tester sits or lies on the bed’s edges and describes how it feels. Then we place a set of weighted plates on the bed’s edges and measure how much the edges sag. We use three sets of plates to resemble light, average, and heavier sleepers. For this test, if we measure any sagging less than five inches, we consider it a good result. I’ll explain how each test was conducted and played out below.
Feel Test
Our tester, Melanie Kassel, sat and rested on the firm side of the Plank’s edges to provide a subjective feel test. She wasn’t pleased with the experience and gave it a subpar 2/5.
When she sat on the Plank’s edges, she said, “Getting up and down from a seated position, I didn’t necessarily need my hands, but felt way more secure using them. I felt like it would be quite easy to slide off the side if you were seated right on it. Seniors and people with mobility issues likely wouldn’t appreciate the Plank’s edge support.”
When she rested on the bed’s edge, she shared much better results, saying, “When I was lying down, the edge support on the Plank Firm performed much better than when I was seated. I felt secure and like there was no dipping from the sides in any sleeping position. The foam held up and felt very strong—it wasn’t about to let me roll off. It’s a 5/5 here!”
On the extra-firm side, our tester, Caitlin Giddings, experienced excellent edge support, both when she was sitting and lying down on the Plank’s edges. She gave both experiences a perfect 5/5.
When she sat down on the bed’s edge, she said, “Getting in and out of this bed is as easy as getting in and out of a chair. The edges of this bed are rock-solid.” Likewise, when she rested on the bed’s edge, Caitlin found that when she lay on the edge of the bed, it felt as firm as it did when she was in the center of it.
Weight Plate Test
When we conducted the weighted plate test on the firm side, we measured 3 inches of sagging with the lightweight plate set (5/5), 4 inches with the average-weight plates (4/5), and 6 inches with the heavyweight plates (3/5).
Then, on the extra-firm mattress side, we measured 2.5 inches of sagging with our lightweight plates, 3 inches with the average-weight plates, and 4 inches with the heavyweight plates. The light and average-weight tests received perfect 5/5 scores, and the test for heavyweight sleepers got a respectable 4 stars.
Cooling
Let’s be real: all-foam beds usually aren’t ideal for hot sleepers. Given its construction, it wasn’t surprising that our testers found the Plank offered slightly below-average cooling. After testing, our testers found that the firm side performed slightly better than the extra-firm side, earning 3.5 and 3 stars, respectively.
We used a thermal gun to test how well the Plank dissipates body heat. The test is pretty straightforward. First, we measure the bed’s resting temperature. Then one of our testers lies on the bed for about five minutes and quickly measures the bed’s sleep surface temperature again. If the bed’s surface temperature doesn’t rise more than eight degrees, we consider it a great choice for hot sleepers.
On the firm side of the Plank, our tester, Caitlin Giddings, measured a starting 65.8 degrees Fahrenheit. After she lay down on the bed for seven minutes, she got up and measured 74.7 degrees Fahrenheit on the bed’s surface. The 8.9-degree increase is just a bit above what we’d consider good cooling, but not awful considering the Plank’s all-foam design.
Caitlin also noted how she felt resting on the Plank, “The mattress doesn’t warm up very much when I lie on it. It didn’t feel crisp or cool to the touch when I climbed in, but it didn’t feel very warm. I think it has fairly good cooling.”
On the extra-firm side, our tester, Melanie Kassel, did the same test. Her initial reading was 65.9 degrees Fahrenheit. After five minutes, she measured an 11.3-degree increase to 77.2 degrees. We wouldn’t consider this a great score.
Despite that, Melanie still felt it wasn’t too warm. She actually would recommend it to hot sleepers who want a firmer all-foam bed. During her evaluation, she stated, “I didn’t feel the mattress get super hot. The foam is obviously quite dense (especially on the extra-firm side). It makes sense that it would trap heat over time. But the cover is one of the coolest I’ve ever felt. I think the temperature increase is more a reflection of my body heat in a super cold studio. I don’t have a problem recommending this to hot sleepers.”
Overall, hot sleepers may want to consider a mattress with stronger cooling based on our objective thermal gun results. But given our tester’s notes, some hot sleepers may find the Plank cool enough. I’d add that those particularly interested in the Plank for its firmness and dual-sided design might want to consider adding the $150 Glaciotex topper for enhanced cooling. Our testers found this cover highly effective and said it may address concerns about overheating.
Motion Isolation
If you’re a light sleeper, sharing the bed with someone who moves around at night can mean restless nights and resentment. A mattress with good motion isolation helps prevent sleepers from waking each other at night. When it comes to this dual-sided mattresss, the extra-firm side was a clear winner over the firm side, with scores of 4.3/5 and 3.3/5, respectively.
To test this feature, we perform two tests: ripple and partner. For the ripple test, we place a jar of water on one side of the bed and see how much it moves when one of our testers gets in and out of the bed and changes sleeping positions next to it.
Caitlin Giddings did the ripple test on the Plank’s firm side. When she got in and out of the bed, she wrote, “When I tried to simulate heavy movements, like shaking the bed, the water splashed around but didn’t leave the glass. I’d say the mattress’s memory foam top layer does a fairly good job of isolating motion.”
On the extra-firm side, Melanie Kassel performed the same ripple test. When she got into bed, she said, “The water barely moves. The Plank Firm has surprisingly good motion isolation for how stodgy and dense the foam is.” Then she moved forward with the test, adding that the water rippled a bit more when I changed positions than when I got in and out of bed. But the glass remained stable.
The second test is called a partner test. On the firm side, Caitlin rested near fellow tester, Sosha Lewis, who was changing positions and described how much she felt their movements. Caitlin admitted to feeling all of Sosha’s “tossing and turning”, but it was dampened enough not to bother her. She gave this test a 3/5, saying there was a “slight springboard effect” on her side, likely due to the mattress’s bounce.
Melanie tried the partner test on the extra-firm side and found better results. Giving the test a 4/5, she reported, “I could feel a few of my fellow testers’ movements, but the general motion was stifled, and I couldn’t tell when she got out of bed at all.”
I’d only recommend the Plank Firm to couples who both really need and find comfort in a super-firm bed. There are better all-foam mattresses out there for isolating motion. But the Plank did a pretty good job considering its firmness and bounce.
Response
A properly responsive mattress adapts to your movements with consistent bounce and support. As a combination sleeper myself who changes positions all night, I’ll attest to how important responsiveness is, especially when you switch from your back to side mid-dream. Our testers gave the Plank’s firm side a standout 5/5 for responsiveness and a 4/5 for its extra-firm side.
The scores reflect a tester switching sleeping positions and recording how easy it is to do so without sinking into the bed. Caitlin gave the 5/5 score for the firm side, saying, “My body didn’t sink at all into the bed—I felt like I was just floating lightly on its surface. It’s so firm that I barely left a dent or a mark in it.”
Melanie tried the extra-firm and described it, “You’re squarely on top of the bed, no sink at all, so there’s no quicksand feeling as you change positions.” She explained her lower 4/5 score: “The dense foam wasn’t responsive enough to lend you a springy burst of motion.”
Again, this bed is not for fans of comfort foams or those who just want to sink into its comfort layers. But, for couples and combination sleepers who want a rock-solid bed, the Plank Firm is a definite top pick based on my research.
Sinkage: Moderate (Firm Side)/Light (Extra-Firm Side)
We had testers place a 44-pound kettlebell on top of the Plank Firm and measured how much it sank into the bed’s support layers. Our in-house tester measured 3.4 inches of sinkage on the firm side. Sosha Lewis measured a tiny 1.5 inches of sinkage on the extra-firm side. For context, average (moderate) sinkage is considered about 3.12 inches. So you can expect slightly above average sinkage on the firm side of the Plank, and an unsurprisingly minimal amount of sinkage on the extra-firm side.
Bounce: High
When assessing a bed’s bounce, we drop a weighted ball onto it and quickly measure how high it bounces. When we dropped the ball on the extra-firm side of the Plank, we measured a whopping 26-inch bounce height. Although the ball bounced 6 inches lower on the firm side, both sides’ bounce heights were well above the average, at 17.89 inches.
This is unusually high for an all-foam bed, but it makes sense considering how firm the Plank is. This means the Plank is a bed you can move around on, and even kids would love the chance to jump on. We gave the Plank a 5/5 for its bounce.
Noise
Our tester gave the Plank a 5/5 for keeping quiet while sleeping on it (noise). The tester just rolled around on the bed and gauged the amount of creaking or mattress noise they heard.
They explained their findings, saying, “This mattress does not make any noticeable noise at all. The mattress is so firm that it does not release any crunch from the materials (aka no springs here).”
All-foam beds tend to be quieter than innerspring or hybrid beds anyway. When you factor in the Plank’s firm support foam components, this score makes even more sense.
Sex
When it comes to sex, both sides of the mattress got 4.6/5. I got these scores by averaging out the bed’s edge support (full-surface support), noise (don’t want to wake the neighbors), and responsiveness (you want to be able to move around). I’d definitely recommend both sides of the Plank for sexually active couples.
But if you and your partner find the Plank way too firm for your liking, you can check out some other great options in our best mattresses for sex or best mattress for couples articles.
Adjustable Base Compatibility
Brooklyn Bedding claims the Plank should work with an adjustable base, but we found different results. When our tester tried it out, they said, “No bend and a significant gap [between the bed and the base], it doesn’t work at all.” They gave the Plank a 1/5. I wouldn’t recommend it if you’re looking for a bed that works with your existing adjustable foundation.
Considering how firm the Plank is, these results made sense. Bending the Plank could even affect the bed’s firmness, stability, and longer-term durability, in my opinion. If you’re looking for a bed that works well with adjustable bases, consider our top picks in our best mattresses for adjustable beds roundup.
Plank Firm Customer Experience Scores
Customer experience scores reflect how simple it is to receive and set up your bed. This also includes trials, warranties, and similar fine print. Below, I go through all of this for the Plank Firm.
Trial Period
The Brooklyn Bedding Plank comes with a 120-night trial. We gave the Plank a 4/5 for this. This is better than some generic mattresses, but still less generous than comparable mattress brands that offer full-year trials. Notably, Brooklyn Bedding encourages customers to give the Plank 30 full nights of rest before really assessing whether it’s the right bed for you.
Warranty
The Plank offers a limited lifetime warranty. Hard to beat this, but we gave the Plank a 4.5/5 rather than a full 5 because of some fine print. When you return the Plank, whether during its trial or due to any issues over time, a $99 return fee applies.
Unboxing and Moving
The Plank is shipped in an easy-to-open box. Maybe you’re super strong, but for the sake of your lower back, I’d really suggest having a friend or extra set of hands to help move it into place when it arrives. The queen-size Plank is over 100 pounds, and arrives in a box that is 18″ x 18″ x 48″, so it may take some finagling to get it to your bedroom.
Readiness After Unboxing
The Plank arrives compressed as a bed-in-a-box to your home and takes 24-48 hours to fully expand to its appropriate, ready-to-use shape, according to Brooklyn Bedding. Experiences might differ here, and you can use it immediately, but it’s best to give it some time to expand for the best results.
Off-gassing
Brooklyn Bedding says that any new mattress may have a chemical smell (off-gassing), but it should dissipate “within a few days.” This is likely a case-by-case basis. But I’d say you should expect minimal off-gassing from the Plank, as it uses more eco-friendly CertiPUR-US-certified foams.
Plank Firm Construction
The Plank Firm is an all-foam bed, but it is designed to be firmer than most others on the market today. I’ll walk you through its materials and construction to let you know exactly what you’re in for.
Mattress Height & Weight
The Plank Firm is on the shorter side at 10 inches. Its hybrid upgrade, the Plank Firm Luxe mattress, is 13 inches. Because it is made of only foam variations, this 10-inch height is reasonable (consider that the Firm Luxe has a six-inch layer of pocketed coils). Depending on the size, the Plank Firm weighs anywhere from 58 pounds (twin-size) to 120 pounds (king-size).
Materials
The Plank Firm is made with knitted, breathable cotton and various foams. All its foam components are GREENGUARD Gold and CertiPUR-US certified, which means they use a more eco-friendly manufacturing process and may be more hypoallergenic than the foam materials of cheaper brands.
Layers
The Plank Firm has tight-knit cotton covers on each side. These covers are designed to be sturdy yet breathable. Both quilted-top cotton covers are 0.75 inches thick.
On the firm, ‘softer’ side, there is an additional 2-inch responsive foam layer for added comfort (it’s still going to be super firm, don’t worry about that).
On the extra-firm side, there’s nothing underneath you but the bed’s massive six-inch high-density polyfoam layer, which acts as the bed’s core support foundation.
The construction is simple, firm, and what you might expect from an all-foam mattress. For hot sleepers, I would suggest adding the Glaciotex cooling cover ($150 fee).
It’s made with polyester and cooling fabrics, which may soften the surface (just a bit) while helping enhance temperature regulation. Our testers have found it to be one of the best cooling covers they’ve tried, and a great way to turn a decent cooling mattress into an excellent one.
How To Try and Buy The Plank Firm Mattress
Brooklyn Bedding has partner showrooms across the U.S. that carry the Plank Firm, so you can try it in person. The best way to find one near you is to check out their showroom locator on their official site.
While you won’t be able to try it out in person beforehand, given the Plank Firm’s trial period, I would say the easiest way to get the Plank is to order it online directly from its official site. Amazon also sells the Plank Firm.

How The Plank Firm Compares
The Plank Firm is one of the firmest all-foam mattresses you can find. This, plus its dual-sided use, makes it quite unique and a great choice for heavier and stomach sleepers. But if you’re still not sure it’s the right pick for you, I paired it with a few of the other mattresses we’ve tested.
- Titan Plus Core – Better pressure relief
- WinkBed Mattress – Three firmness options
- Helix Dawn Mattress – Better cushioning comfort
|  |  |  | |
| Rating | ||||
| Firmness | Firm: 8/10 | Medium-firm: 7/10 | Multiple firmness options | Firm: 7.5/10 |
| Material | Foam | Hybrid | Hybrid | Hybrid |
| Cooling | — | — | — | |
| Best For | Back Sleepers, Stomach Sleepers, Back Pain | Back Sleepers, Stomach Sleepers, Back Pain | Side Sleepers, Back Sleepers, Stomach Sleepers | Back Sleepers, Stomach Sleepers, Couples |
Plank Firm vs. Titan Plus Core
The Titan Plus Core is a hybrid mattress that features coils in addition to foam. Both mattresses accommodate heavier sleepers, with the Titan Plus Core being designed specifically with heavier (over 230 pounds) sleepers in mind. However, the Titan Plus Core, in part due to its sturdy 900-plus-coil layer, has a slightly higher weight capacity of 1000 pounds compared to the Plank Firm’s 950 pounds.
Like the Plank, the Titan is firmer than average at 7/10, but can only be used on one side, unlike the Plank, and is still less firm than the Plank’s 8/10 and 9/10 firmness options. When I compared our tests of both beds, the Titan’s pressure relief (4.8/5) was significantly better than the Plank Firm’s.
If you are a heavier sleeper and don’t prefer firmer mattresses, the Titan Plus Core is a great alternative to the Plank.
Plank Firm vs. WinkBed
The WinkBed is a luxurious hybrid mattress that is considerably more expensive than the Plank Firm ($2,570 for a queen, without discounts). While the WinkBed isn’t a flippable mattress, it’s available in three firmness options, making it easier to match your preferred firmness to your specific sleeping preferences.
Despite its more ‘luxurious’ pricing, the WinkBed didn’t demonstrate much better performance scores than the Plank Firm in our testing studio. Actually, the Plank blew the WinkBed out of the water when it came to responsiveness. But the WinkBed demonstrated slightly better edge support (4.4/5), which may make it a tad more ideal for people who struggle to get in and out of bed.
If you’re looking for a super-firm mattress, I would say the Plank Firm mattress is a better choice, even though WinkBed offers multiple firmness options. Especially when you consider the different mattress costs.
Plank Firm vs. Helix Dawn
The Helix Dawn is also on the firmer side, at 7/10, slightly above the industry average. The mattress also has coils and more comfort-focused, cushiony foam, unlike the Plank Firm. Both the Helix Dawn and Plank Firm are owned by Brooklyn Bedding, so they offer the same customer experience (120-night sleep trials, free shipping, and limited lifetime warranties).
Both mattresses had similar quality cooling and a 5/5 responsiveness score. However, the Helix Dawn had slightly better edge support (4.6/5), which may make it less likely to sag over time than the Plank Firm. Likely due to the Plank’s firmness and all-foam construction, the Dawn had far worse motion isolation (2.7/5) when we tested it, meaning couples who both like a tough firmness, of course, may appreciate the Plank Firm more for this.
