Plank Mattress Video Review

We hope you enjoyed the video above. However, it’s hard to fit all the details about this mattress into one video. Keep reading to learn more about the Plank bed-in-a-box mattress.

Company Policies Overview

If you’re new to the whole bed-in-a-box concept, you’ll be surprised by just how easy and convenient it is to order a mattress online these days. Companies like Plank (Brooklyn Bedding) offer very friendly customer policies.

First, the Plank mattress ships for free and arrives at your doorstep compressed and rolled-up in a box. From there, you’ll want to move the box to your room and proceed to unroll the bed onto your foundation or box spring. However, it’s recommend you let the mattress fully inflate for about 48-72 hours before you actually sleep on it.

Once the mattress arrives, Plank (or Brooklyn Bedding) offers you a 120 night risk-free sleep trial. This is part of the reason why buying a bed online is so attractive. The company is basically giving you four full months to test the bed in the comfort of you own your home and decide whether you like it or not.

That sure beats 45 seconds in your local mattress store with an annoying salesperson standing over you, right?

If, after 30 nights, you do decide that the bed isn’t for you, no big deal, just contact customer support and they’ll take care of everything. First, they’ll arrange for a third party service to come retrieve the mattress from your home for no additional charge.

Once that happens, just provide proof to the company that the bed has indeed been picked-up and they’ll issue you a full refund.

The Plank mattress is also backed by a 10 year limited warranty. It’s always a good idea to read through the warranty before purchasing. You can check out the full warranty on the company’s website.

Also, just so you know, the terms we just went over are pretty standard for the bed-in-a-box industry. Most beds you buy online will come with free delivery, free returns, a long trial period and an extended warranty.

Plank Mattress Pricing And Coupon Code

The Plank mattress lands smack dab 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 actually a pretty 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 very aggressive when it comes to sales, discounts and promo codes. They’re almost always running some sort of promotion to make the mattress even more affordable. In fact, we often see them run a 20% off sale. Check the box on the right to see what kind of discount you can currently get.

Keep Your Weight In Mind

Your weight is more important than you realize. The same mattress will feel quite different to various sized individuals. As such, we try to always bring up the weight subject in every review, comparison and best list we publish so readers are aware.

In very general terms, heavy sleepers (250+ pounds) will feel like most mattresses are a bit softer than small and average size people. That’s because big folks exert more force on a bed and as a result sink into the soft top layers more.

Petite and medium size sleepers, on the other hand, will generally feel like most mattresses are firmer than their heavier counterparts. That’s because small individuals place less pressure on a bed and as a result sleep more on top of the mattress.

In our reviews, we typically write through the body or perspective of an average size person, however, we will also reference other body types throughout this post. Nevertheless, keep your weight in mind as you progress down the page.

What’s The Deal With Double-Sided Mattresses?

As we mentioned in the title, Plank is one of the few mattresses out there that is double-sided, meaning you can sleep on either side of the bed. Further, the Plank mattress comes in two different 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 better 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 since they offer more rotation options. The more you rotate your bed, the less likely body impressions and sagging will form in the mattress.

What Is The Plank Mattress Made Of?

The Plank mattress is comprised of 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
Transition Layer – 2″ of TitanFlex support foam
Main Support Layer – 7″ of high-density poly foam
Soft-Side Top Layer – 1.5″ of quilted soft proprietary foam

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 now purchase a cooling top panel for your Plank mattress. We didn’t test out the cooling model, but apparently the materials are very 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.

The Cover On The Plank Mattress

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 really not a big deal since you clean the majority of mattress covers the same way. Really, there’s only a few bed-in-a-box mattresses out there that feature removable and machine washable covers.

If you happen to spill something on the bed or have an accident, 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 Bed

In terms of feel, the bed has a firm, neutral-foam feel, which isn’t a big shock considering the bed is comprised entirely of proprietary foam layers. In other words, the bed doesn’t use any memory foam or any kind of soft pillow top.

Now don’t let the term ‘firm’ throw you off. The top layers on both sides are still soft and comfortable but you just don’t really sink into the bed at all. You sleep more on top of the mattress and your hips stay in horizontal alignment with the rest of your body.

The Plank mattress provides a lot of support

The top layers are also quite 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. As we alluded to above, you don’t really sink into the top layers and as a result sleep more on top of this side.

Similarly, we think the soft side lands on the firmer side of the spectrum as well. 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 so with that in mind it’s not a huge surprise.

You might be asking why did Plank make the mattress so firm? Honestly, that’s what the company was going for. Their goal was to create a firm, durable bed. In fact, the company actually 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.

Is The Plank Mattress Good For Side Sleepers?

In short, no the Plank mattress is not ideal for side sleepers. As mentioned above, both sides are quite firm and don’t offer much pressure relief.

Typically, side sleepers will want a mattress that is on the softer side of the spectrum and that cradles their pressure points well (i.e. hips and shoulders). Ultimately, that’s just not what the Plank mattress was designed to do.

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

Is The Plank Mattress Good For Back And Stomach Sleepers?

Yes, this is who this mattress was made for. The Plank bed-in-a-box is an ideal 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.

For combo sleepers, we would say generally speaking, Plank should be just fine, but it depends on how much time you spend on your side.

Heavy And Large People

This is a tough subject. We have mixed feelings about the Plank mattress in regards to large and heavy people.

Normally, we point heavy sleepers towards beds that contain coils for two reasons. One, coils tend to be more durable than support foams. The second reason is that coils provide more support than dense foams (they provide some resistance against all the extra force big folks exert on a bed).

Now, if we breakdown those two points in comparison to the Plank mattress, the first advantage coils offer (durability) sort of gets tossed out the window given the Plank’s firmness, rotation flexibility and overall thickness.

In our eyes, the second point still stands though. Coils would be preferable for big folks as opposed to the 7″ poly foam the Plank uses for its support structure.

All in all, 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.

Does The Plank Mattress Sleep Cool?

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

The term ‘cool’ gets tossed around frequently in the bedding industry but the truth is mattress temperature is hard to nail down given all the external factors at play. For example, what climate you live, what sort of pajamas you wear and what kind of sheets you use, among other things all play a big role in how cool or warm you sleep.

The Plank mattress doesn’t using 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 The Double-Sided Plank Mattress Good For Couples?

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

First, the Plank bed limits motion transfer extremely well. It passed our tests easily. We noticed very little motion that was transferred from one side of the bed to the other.

This is good news for people who share a bed with an active sleeper who either switches positions frequently or gets up a lot throughout the night (midnight run to the cookie jar, anyone). 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.

Next, 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.

Conclusion: Does Minimalism Work With A Mattress?

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.
