Plank Mattress Review

The Plank Mattress is a flippable, all-foam bed sold at competitive prices. The Plank measures 11.5 inches in thickness and rates firm, or 7 to 8 out of 10 on one side and extra firm, or 9 to 10 on the other side. Created by Brooklyn Bedding, the Plank Mattress is sold on its own dedicated website, separate from the company's other mattress offerings.

Brooklyn Bedding allows customers the option of upgrading the mattress by adding a cooling panel on both sides of the bed. The cooling panel is made of phase change material, which is a technology that absorbs and transforms body heat to keep the bed temperature neutral. Customers must pay an additional cost for the cooling top panel.

Brooklyn Bedding sells other firm beds in addition to the Plank, but they differ in significant ways, such as price, thickness, and feel. No other Brooklyn Bedding mattress is available in extra firm, or 9 to 10 out of 10 on the firmness scale. The Aurora, Signature, Spartan, and Titan all come in firm, or 7 to 8 in firmness. These are all hybrids rather than all-foam beds, however.

Plank Mattress Review: Our Verdict

Choose The Plank if...
  • You sleep on your stomach. Stomach sleepers need a firmer mattress to avoid putting strain on their necks, and the Plank rates highly with this sleep preference group.
  • You weigh over 230 pounds. Since this bed is on the firm side, it provides adequate support to heavier sleepers.
  • You tend to sleep hot. The Plank stays cooler than other all-foam beds, especially if you opt for the optional cooling panel.
  • You prefer a responsive bed. Although the Plank Mattress is all-foam, it feels springier and doesn't "hug" the body as closely as many foam beds do.
Keep Shopping if...
  • You weigh less than 130 pounds. The firmness of this mattress can cause pressure points in lighter weight sleepers.
  • You share a bed and are sensitive to movement. The Plank doesn't isolate motion as well as other all-foam beds, so sleepers will feel their partner's movements.
  • You want a conforming mattress. Although the Plank is made of foam, it doesn't "hug" the body like many all-foam beds do.

How Much Is the Plank Mattress?

The Plank Mattress costs $999 for a queen-sized mattress. When customers opt for the cooling top panel add-on, that price increases to $1,249.

These prices are competitive given the constructions and materials of the all-foam Plank Mattress. Since the Plank is flippable, it offers two firmness levels in one bed. Flippable mattresses tend to cost more than those that do not flip.

When customers opt for the cooling top panel, both sides of the mattress are lined with quilted phase change material. Phase change material is a unique technology not found in most mattresses and generally increases the price of a bed.

How Does the Plank Mattress Feel?

Although the Plank Mattress is an all-foam bed, it doesn't have the highly conforming feel associated with memory foam. Instead, the Plank Mattress feels more firm and flat. The foam comfort layer on the firm side of the mattress is latex-like and has a similar feel. The extra firm side only has quilted fiber rather than foam as a comfort layer.

Sleepers do not sink in deeply or feel very "hugged" by the Plank Mattress. That said, the firm side of the bed provides more cushion than the extra firm side. Most sleepers will prefer the firm side. Many sleepers, especially those of lighter weights, will develop pressure points when lying on the extra firm side of the bed.

Because the Plank Mattress is more responsive than conforming, it’s a bit easier to move around on. Sleepers can move easily to roll over or get off the bed since there are no memory foam impressions inhibiting their movement. The bed's springiness also facilates rather than inhibits movement during sex.

What Is the Plank Made Of?

The Plank Mattress is constructed with the following materials:

  • Cover Material: Phase Change Material (cooling panel option only)
  • Comfort Layers: .75" quilted fiber, 2" TitanFlex polyfoam
  • Support Core: 7" polyfoam, 1.5" quilted fiber

The Plank Mattress is an all-foam bed that comes with the option to add a phase change material cooling layer as a paid upgrade. Since it's a flippable mattress, either side can face up. Layers function as either comfort layers or the support core depending on which side of the mattress is facing up at a given time.

When the Plank Mattress is flipped to the firm side, it has two comfort layers. The uppermost comfort layer measures .75 inches and consists of quilted fiber. Below that lies 2 inches of TitanFlex polyfoam. TitanFlex is latex-like and not memory foam, which is why the bed feels more responsive than conforming.

The support core consists of 7 inches of polyfoam when the Plank Mattress is on the firm side. Below that lies a 1.5 inch layer of quilted fiber. When this layer is on the bottom of the mattress, it has little to no impact on the mattress's feel.

When the Plank Mattress is flipped to the extra firm side, it has one comfort layer. One-and-a-half inches of quilted fiber provide cushion. They sit atop 7 inches of polyfoam, which is what makes the mattress feel extra firm. Below this polyfoam layer lies 2 inches of TitanFlex polyfoam and .75 inches of quilted fiber.

Does the Plank Isolate Motion?

Rating: Firm Side: 2/5 Extra Firm Side: 1/5
The Plank Mattress doesn't isolate motion as well as most all-foam mattresses. Generally, all-foam beds are known for isolating motion well. Memory foam in particular tends to absorb movement, rather than transfer it across the surface of the mattress.

Although it's an all-foam bed, the Plank Mattress doesn't contain memory foam. Instead, it contains denser, firmer polyfoam that doesn't absorb as much motion. As a result, some sleepers who share a bed with a partner might be disturbed by motion throughout the night.

When one person rolls over or gets in or out of bed, motion will likely transfer across the Plank Mattress. Sleepers who are sensitive to motion transfer should opt for a bed that better absorbs motion. Conforming memory foam comfort layers tend to absorb motion well.

Does the Plank Sleep Cool?

Rating: Firm Side: 3/5 Extra Firm Side: 4/5
Firm Side with Cooling Panel: 4/5 Extra Firm Side with Cooling Panel: 5/5

The Plank Mattress stays fairly cool throughout the night. Because the bed doesn’t conform too closely to the sleeper, it doesn't trap heat the way most all-foam mattresses do. Its latex-like foam layer and quilted fiber comfort layer promote temperature neutrality.

The Plank is one of the few all-foam beds capable of staying cool. It compares to hybrid and innerspring mattresses in terms of temperature neutrality. Generally, innerspring mattresses stay cooler than all-foam beds because of airflow in their spring layer.

Sleepers that purchase the optional cooling panel will enjoy an even cooler bed than those who do not. Also, sleepers who use the Plank Mattress on its extra firm side enjoy more cooling than those who use the bed on its firm side.

Will It Sag Along the Edges?

Rating: 4/5
The Plank Mattress has strong edges. This edge support is important because it allows sleepers to use the full surface of the bed. When edges are weak, sleepers feel at risk of rolling off the bed when they sit or lie near the edge. Weak edges can buckle and fold under body weight, but that won't be a problem for most people on the Plank.

The strong edges of the Plank Mattress come from the bed's overall firmness. Generally, all-foam beds have weaker edges, but that isn't the case here. The firm and extra firm firmness levels of the bed extend to the edges, keeping them stiff and unlikely to sag under most people's body weight.

Is It Good for Sex?

Rating: Firm Side: 3/5 Extra Firm Side: 2/5
How the Plank Mattress performs in terms of sex depends on which firmness level of the bed is currently in use. The firm side, which is the side most people prefer, is good for sex. This side provides a more responsive feel that facilitates, rather than inhibits, movement. The mattress also has strong edges that allow for full use of the surface of the bed.

The extra firm side of the Plank Mattress is so firm that it feels uncomfortably hard to many people. This firmness can create pressure points and discomfort not only during sleep, but also during sex.

What About Off-gassing?

Rating: 2/5
Like most all-foam beds, the Plank Mattress off-gasses a fair amount. Off-gassing occurs when volatile organic compounds (VOCs) escape from newly manufactured products in the form of gas. Generally, these VOCs have a chemical smell. Some people don't mind the smell, but others are more sensitive to it.

The Plank Mattress releases a fairly strong odor upon being opened. This odor dissipates and becomes virtually undetectable within a few days. People who are particularly sensitive to smells might want to put the newly opened mattress in a well-ventilated room, then avoid it for a day or two after unboxing.

What Type of Sleeper Is the Plank Mattress Best for?

Overall, the Plank Mattress works best for stomach and back sleepers and rates lower with side sleepers. Of course, body weight also factors into the equation, influencing how much comfort sleepers experience on the bed.=

Side Sleepers: Side sleepers find the least comfort in the Plank Mattress. Many side sleepers prefer a softer bed. Of course, weight is a factor. Side sleepers weighing over 230 pounds generally like the Plank more than side sleepers weighing under 230 pounds.

A too-firm mattress can create pressure points in side sleepers. Many side sleepers, especially those weighing under 230 pounds, experience pressure in their necks and hips while lying on the Plank Mattress. A too-firm mattress doesn't promote spinal alignment in side sleepers and can lead to discomfort or even pain over time.

Combination Sleepers: The Plank Mattress rates highest with stomach sleepers and performs well with combination sleepers that primarily sleep on their stomachs and backs. Generally, this group likes firmer mattresses than sleepers with other sleep position preferences. A firm mattress helps keep a stomach sleeper's spine aligned.

When a mattress is too soft, the stomach sleeper's body can sink into the mattress too deeply. When this occurs, the sleeper's back arches and pressure develops in the neck. As a result, stomach sleepers using a too-soft mattress often experience lower back and neck pain.

Back Sleepers: Back sleepers find that the Plank Mattress is firm enough and provides adequate lumbar support. When a mattress is too soft for a back sleeper, their back will arch. This arch can lead to discomfort and lower back pain.

Weight also has an impact on the amount of comfort back sleepers feel on the Plank Mattress. Sleepers weighing under 130 pounds might find that the Plank feels too firm and, as a result, doesn't relieve enough pressure. Back sleepers weighing over 130 are more likely to feel both support and comfort on this bed.

Stomach Sleepers: Stomach sleepers, like back sleepers, usually need more firmness and support from their mattress. Most people carry extra weight in their chest, midsection, and hips, so sleeping face-down on a softer mattress can lead to excessive sagging. Thanks to a firm feel on both sides, the Plank Mattress is well suited to people who primarily sleep on their stomachs – provided they weigh at least 130 pounds.

Comparatively, stomach sleepers weighing less than 130 pounds will probably find the Plank Mattress a bit too stiff. Although this position often demands a firmer feel, sleepers in this weight group typically need more contouring from their mattress in order to reduce pressure points around the shoulders and waist.

How Does Body Weight Impact the Plank Mattress's Performance?

Because the Plank Mattress has firm and extra firm options, it works best for sleepers weighing over 130 pounds. Back, stomach, and combination sleepers in this weight range tend to find the best mixture of comfort and support on this bed. Side sleepers, even those over 130 pounds, can find that the Plank feels too firm to promote spinal alignment and relieve pressure.

Most sleepers weighing less than 130 pounds will find that even the softer side of the Plank is too firm. When a mattress is too firm, it doesn't relieve pressure and instead creates pressure points. Over time, these can lead to discomfort and even pain.

The Plank Mattress especially excels at supporting sleepers weighing over 230 pounds. Many sleepers in this weight range, especially those who sleep on their stomachs or backs, find that the Plank is one of the best mattresses for them. Unlike softer mattresses, the Plank provides adequate back and abdominal support to these groups of sleepers.

Is the Plank Mattress Good for Couples?

Many couples find that the Plank Mattress works well for their needs. The Plank is a good fit for couples in which both people weigh over 130 pounds and prefer a responsive-feeling bed. Also, stomach and back sleepers of all weight groups tend to prefer the Plank Mattress more than side sleepers do.

The Plank Mattress isn't the best choice for couples in which one or both people weigh less than 130 pounds. The bed feels overly firm to this weight group and can cause pressure points and discomfort.

Couples that sleep hot will also enjoy the bed. Those who tend to sleep very hot should consider upgrading the mattress by purchasing the optional cooling panel. With this add-on, the Plank Mattress becomes one of the coolest sleeping all-foam mattresses available.

Sleepers that are very sensitive to motion transfer might want to opt for a bed that isolates motion better than the Plank. Most sleepers aren't bothered by motion transfer on this bed, but sensitive sleepers can be disturbed by it since the Plank transfers more motion than most all-foam beds do.
