Plank Mattress Pricing And Coupon Code

The Brooklyn Bedding Plank lands in the middle of the bed-in-a-box industry in terms of price. Considering its high quality construction and versatility, we think Plank is a good value.

Here’s how MSRP pricing breaks down by size.

SizePrice (MSRP)
Twin XL$749
King / Cal King$1,249

However, those are just the MSRP prices. Plank is aggressive when it comes to sales, discounts and promo codes. The company is almost always running some sort of promotion to make the mattress even more affordable. In fact, we often see a 20 percent off sale. Check the box on the right to see what kind of discount you can get.

Brooklyn Bedding Plank Feel And Firmness

Plank is one of the few mattresses that is double-sided, meaning you can sleep on either side of the bed. Further, the Plank mattress comes in two firmness levels.

In other words, one side is firmer than the other. This allows consumers to test both sides of the bed and decide which one suits their sleeping habits.

Alternatively, you can use both sides to extend the life of the mattress. Flippable mattresses tend to be more durable than traditional beds because they offer more rotation options. The more you rotate your bed, the less likely body impressions and sagging will form in the mattress.

The Plank Bed has a firm, neutral feel on the softer side and a firmer one on the flip side. It doesn’t feel viscous like memory foam — instead, it feels like classic responsive foam. In addition, motion transfer is minimal. If you share your bed with a partner, you probably won’t notice them moving or shifting in the middle of the night.

Plank Mattress Construction And Design

This mattress has four foam layers and totals 11.25″ thick. Starting from the firm side and working down, here’s how the mattress is constructed:

  • Firm-side top layer: 3/4″ of quilted soft proprietary foam for supportive comfort 
  • Transition layer – 2″ of TitanFlex support foam to provide a transition in between foams
  • Main support layer: 7″ of high-density poly foam which will provide the bulk of the bed’s support
  • Soft-side top layer: 1.5″ of quilted soft proprietary foam for more plush support

Basically, as you can see above, the primary difference between the two sides comes down to the thickness of the soft proprietary foam the bed uses for its two end pieces. The firm side has 3/4″ of soft foam and a layer of firm support foam underneath, while the soft side has 1.5″ of soft foam on top of the bed’s main support layer.

As of early 2019, you can purchase a cooling top panel for your Plank mattress. We didn’t test out the cooling model, but the materials are similar to what you find in Brooklyn Bedding’s Aurora mattress. It does raise the cost a bit ($200 more for a twin and $250 more for a queen/king), but it’s a good option for those who tend to warm up while they sleep.

Plank Mattress Cover

Wrapping the four foam layers is a non-removable quilted cover. Overall, it’s soft, comfortable and gives the bed a premium look.

While most people prefer a removable cover, it’s not a big deal because you clean the majority of mattress covers the same way.

If you spill something on the bed, the company recommends you spot clean the cover with a mild detergent and some water.

Alternatively, if keeping the cover clean is super important to you, you may want to check out the Plank Mattress protector or popular mattress protectors on Amazon.

Firmness Rating For Both Sides Of The Plank Bed

The bed has a firm, neutral-foam feel.

The top layers on both sides are still soft and comfortable, but you don’t sink into the bed. You sleep more on top of the mattress, and your hips stay in horizontal alignment with the rest of your body.

The top layers are also responsive, meaning they pop back into place almost immediately after pressure is released (unlike memory foam). This is a good thing for active sleepers who move around a lot throughout the night. Generally, active sleepers will find it easier to switch between positions on responsive beds.

Moving on, we think the firm side of the mattress comes in around a firm on our firmness scale.

Similarly, we think the soft side lands on the firmer side of the spectrum. Overall, we rate the soft side around a medium-firm on the firmness scale. After all, remember the difference between the two sides comes down to only 3/4″ of soft foam.

Why did Plank make the mattress so firm? Honestly, the company’s goal was to create a firm, durable bed. In fact, the company uses the tagline “The firmest, flattest, healthiest way to sleep”.

If you prefer a softer mattress and you want to stick with Brooklyn Bedding, we recommend checking out the Bowery, Signature or Aurora mattresses.

Suitable Sleeper Profiles For The Plank Mattress

Side Sleepers

The Brooklyn Bedding Plank is not ideal for side sleepers. As mentioned above, both sides are firm and don’t offer much pressure relief.

If you spend a lot of time on your side, we’d recommend checking out our list of the Best Beds For Side Sleepers.

Back And Stomach Sleepers

The Plank bed-in-a-box is an ideal option for back and stomach sleepers.

The Plank mattress is a great option for back and stomach sleepers

The bed provides more than enough support for these types of sleepers. When laying on your back or stomach, your hips and trunk never sink-in or dip down to the point where your spine is no longer in proper alignment.

Combo Sleepers

Combo sleepers may find they spend more time on their stomach or back than on their side. As mentioned, the Plank is a bit too firm for a side sleeper, potentially creating pressure points on shoulders and hips. The one positive is, the firmer mattress will encourage sleepers to spend more time on their back, which may be a better sleep posture.

The foam has a neutral feeling that may feel too firm for a petite sleeper. Petite body types looking for a firm mattress may be happy with the Plank mattress, but everyone else should find a different mattress.


The Plank is best for people of average body type. The foam provides the right support without being overly firm or mushy. As for durability, an average-weight person shouldn’t put as much wear and tear on the mattress as a heavyset individual.


We have mixed feelings about the Plank in regards to large and heavy people. Normally, we point heavy sleepers towards beds that contain coils because coils are more durable and supportive. If you’re a large body type, we’d say hybrid and coil mattresses would be more ideal, but if you’re dead set on an all-foam mattress, the Plank is one of the better options out there.

Plank Mattress Temperature Regulation

This is another tough subject for us to opine on but ultimately we think the Plank mattress sleeps temperature neutral.

The Plank bed doesn’t use any special cooling textiles or materials, but given its firmness level and the fact that you sleep more on top of the bed should at least help prevent you from warming up at night.

Is Plank A Good Mattress For Couples?

Yes, as long both partners are primarily back and stomach sleepers. If that’s the case, the Plank is a viable option for couples.

Motion Isolation

First, the Plank bed limits motion transfer extremely well. It passed our tests easily.

This is good news for people who share a bed with an active sleeper. A bed like the Plank that isolates motion well means you’ll feel less of your partner’s movements, which will help you get a more restful night’s sleep.

Edge Support

The Plank mattress provides superb edge support. In fact, it’s one of the best beds we’ve ever tested in this department. As you inch towards the perimeter of the bed, you always feel properly supported and never feel as if you’re going to roll right off.

This is a topic that is especially important for partners who share a smaller size bed (i.e. full or queen). A mattress with good edge support will provide more suitable surface area for both partners to spread out and get comfortable while still receiving the support they need.

Plank Pros And Cons


  • Two-sided foam mattress
  • Firm, neutral support
  • Excellent edge support and minimal motion isolation


  • Not ideal for heavy-set individuals
  • May be too firm, even on the flip side of the mattress
  • Minimal pressure relief could cause side sleepers discomfort

Plank Mattress Review Verdict

Overall, there’s a lot to like about the Plank mattress, however, it’s not going to be the right bed for everybody. We see it being best for a certain type of person. First, you have to like or need a firm bed. Next, you have to sleep primarily on your back or stomach. If you meet that criteria then we think you’ll enjoy the mattress.
