Most new mattresses, including the Plank, may initially emit a “new mattress smell.” All-foam models like the Plank are especially prone to off-gassing odors because they tend to let off volatile organic compounds (VOCs). These chemicals are usually not considered harmful.
Airing out your new mattress before using it can help reduce VOCs and associated odors. To do so, unpack your mattress and leave it in a well-ventilated space until the smells dissipate. Most mattresses finish airing out within a few hours to a few days.

Pros & Cons:
Brooklyn Bedding was in the first wave of companies to join the mattress in a box movement. Today, the company offers pillows, sheets, blankets, foundations, mattress protectors, and multiple mattress models. The current mattress lineup includes the Aurora, the Signature, the Bowery Hybrid, the Spartan, the Bloom, the Titan, the EcoSleep, the Propel, and the Plank Firm.
The Plank, also known as the Plank Firm, is unique among Brooklyn Bedding’s models. This model is one of the firmest mattresses on the market, constructed to provide a flat, even surface. The Plank is flippable with a different firmness option on either side of the mattress. One side of the mattress is firm, rating at a 7 on the 10-point firmness scale. The other side is extra firm, rating at a 9 on the firmness scale.
This mattress is constructed of multiple layers of foam. An optional cooling top panel is also available. The panel uses phase change molecule (PCM) fabric, which is engineered to feel cool to the touch. This adds to the mattress’s temperature regulation, but it does not significantly impact other performance factors.
We’ll discuss the Plank Mattress’s construction, sizing, pricing, performance, customer reviews, and company policies. If you’re considering buying a Plank Mattress, keep reading to learn more.

Sleeping Style and Body Weight
Side Sleepers
The Plank’s firm side rates around 7 on the firmness scale. While this is firmer than side sleepers tend to prefer, some may appreciate the mattress’s even support and light contouring.
Side sleepers who weigh over 130 pounds are more likely to experience contouring and pressure relief. Side sleepers who weigh less than 130 may not sink into the mattress deeply enough for noticeable contouring, so they may experience more pressure around their hips and shoulders.
Back Sleepers
Back sleepers usually prefer an even surface that doesn’t sag, so the firm side of the Plank Mattress is likely to be a good match.
Back sleepers usually prefer an even surface that doesn’t sag, so the firm side of the Plank Mattress is likely to be a good match.The Plank is crafted to maintain an even plane, so it should provide enough support to prevent most back sleepers’ hips from sinking in too deeply. Back sleepers over 130 pounds may experience the best blend of support and cushioning. Those under 130 pounds may feel it is slightly too firm.
Stomach Sleepers
Stable support from the firm side of the Plank Mattress may make it an excellent fit for stomach sleepers.
The Plank Mattress’s firm side is even enough to support most stomach sleepers’ midsections without allowing it to sink in too far. Because the mattress is firm, it may be a particularly good match for stomach sleepers over 130 pounds. Stomach sleepers under 130 pounds are also likely to find the Plank Mattress supportive, but it may be firmer than many individuals in this weight group find ideal.
Side Sleepers
Most side sleepers are likely to find the extra firm side of the Plank Mattress firmer than they’d prefer.
The extra firm side of the Plank Mattress is one of the firmest sleep surfaces on the market, so there is very little give to contour to a side sleeper’s hips and shoulders. This could lead to more pronounced pressure points, especially for side sleepers who weigh less than 130 pounds. Side sleepers who weigh over 130 may also experience pressure points, but those who enjoy an exceptionally firm feel may enjoy the Plank’s extra firm side.
Back Sleepers
Many back sleepers may appreciate the extra firm side’s even support, but some back sleepers may also find it too firm.
Since back sleepers usually benefit from an even, stable sleep surface, the steady support of the extra firm side of the Plank Mattress may work well for some individuals. Many back sleepers suffer from back pain from sleeping on a softer mattress that allows their hips to sink in too deeply. The extra firm side of the Plank is unlikely to allow much if any hip sinkage. However, the extra firm side also does not provide much cushioning. The 1.5-inch comfort layer uses very firm foam without much give, so it may feel too hard to some back sleepers.
Stomach Sleepers
The extra firm side of the Plank Mattress is likely to provide the support stomach sleepers tend to need to prevent their midsections from sinking in too deeply.
The 1.5-inch comfort layer is quite firm, so a stomach sleeper’s midsection is unlikely to sink in very far and their spine should stay well aligned. A firm polyfoam core lies directly under the comfort layer, further reducing the likelihood of excessive sinkage around the midsection. However, some stomach sleepers, especially those who weigh under 130 pounds, may feel like the extra firm side of the Plank Mattress lacks their desired level of cushioning.

Mattress Performance
In addition to the hands-on feedback from our team, we conduct a number of quantitative tests in our Test Lab. The below ratings are based on the experience of our testers.
Plank Mattress Review Breakdown
The Plank Mattress is a flippable all-foam model. Each mattress comes with two firmness options built-in. One side is firm, rating around 7, while the other side is extra firm, rating at 9.
The firm side of the mattress starts with a comfort layer of .75-inches of 1.5 pounds per cubic foot (PCF) quilting foam. This foam is medium-density, meaning it conforms moderately and is more breathable than most higher-density polyfoams.
Next, a 2-inch thick transition layer of 3.5 TitanFlex foam gives deep compression support while preventing the sleeper from sinking in against the firmer core. This TitanFlex foam is engineered to contour to the sleeper’s body while providing responsiveness similar to latex.
The extra firm side of the mattress uses a 1.5-inch layer of exceptionally firm 1.5 PCF quilting foam. Its exceptionally firm feel creates an even plane with little to no give.
Both sides of the mattress are supported by a 7-inch 1.8 PCF polyfoam core, giving the mattress more durability and even support.
The Plank Mattress uses a four-way stretch knit cotton cover. An optional cooling panel is also available for an additional charge. This panel consists of phase change molecule (PCM) fabric that’s cool to the touch to help the sleeper maintain a more even temperature during the night.
