Love to sleep? (Don’t we all?) If you’re ready to protect your sleep schedule with a vengeance, then you’re probably pretty familiar with the various range of products available that claim they’ll give you a better night’s sleep. From the MyPillow to mattresses in a box, there are so many products to choose from. So what about the Pillow Cube?

If you’ve heard about the Pillow Cube but aren’t sure what exactly it is or if it’s even worth its admittedly high price tag, we’re here to help. We’re breaking down everything you need to know about Pillow Cubes and whether or not they’re worth your hard-earned cash. 

What is the Pillow Cube?

Go to pillowcube.com, and you’ll instantly be accosted by a bright turquoise background and a meme-worthy cat proclaiming that the Pillow Cube is “the perfect pillow for side sleepers.” But beyond the brand by the same name’s attempts to seem cool, hip and in with the youth, what’s the truth?

According to the brand, Jay, a family man with a family of side sleepers (himself included), founded Pillow Cube in an effort to find a solution for side sleeping. Tired of stacking pillows to get better neck support, he researched ancient techniques. He discovered that side sleepers throughout history, from Japan to Egypt, would use wooden blocks to provide support and stability while sleeping. Taking inspiration from their efforts, Jay created the Pillow Cube product.

So what is it?

The Pillow Cube is a pillow in the shape of a cube. It’s that simple. The brand and the product have the same name, and the literal design of the product is also the same.  

The cube is made from a breathable memory foam pillow and covered in a silky case, so it gives you support as you rest your neck at a 90-degree angle, versus struggling to find side sleeping comfort with your neck tilted all sorts of odd ways.

Through Kickstarter and social media, Jay hawked his new product, gained some media attention and now you can find multiple versions of the product, including a Pillow Cube Pro and Pillow Cubes for kids.

Your Pillow Cube Options

As with any good pillow, you can choose from a few good options to find the best one for your sleep preferences. 

The Pillow Cube CLASSIC

The Pillow Cube CLASSIC

The Pillow Cube CLASSIC, aka Jay’s first product, comes in a standard and thick variant (the former for those who are 5 feet 4 inches to 6 feet 3 inches tall, the latter for those that are even taller — but both for the same price). The cube is purported to help you “stay cool all night, fall asleep faster, stay asleep longer and wake up happier.”

The pillow’s normal retail price is $90, but it’s not uncommon to find it available on the website for $70. There’s also the option to “ice cube” your pillow for $100 by outfitting your cube with a unique cover that keeps the pillow cooler, longer. 

The Pillow Cube Pro

The Pillow Cube Pro

The Pillow Cube Pro, on the other hand, isn’t really a cube. This is where the brand deviated and decided to offer a rectangular option. This allows sleepers to roll from side to side during the night (whereas with the classic Pillow Cube option, you’re forced to remain in one singular spot, as it’s not big enough to allow for rolling, unless you take the time to reposition the pillow as you do). In short, the pro option is just longer. 

The Pillow Cube Pro comes in at $120, with a thin and standard variant with the option to choose for those either 5’3″ or shorter or 5′ 4″ to 6′ 3″. The thick option for those at least 6′ 4″ is more expensive, at $130. The pro pillow also comes with the option to upgrade with the “ice cube” feature for an extra $30.

Lastly, the third and final current Pillow Cube pillow product is the Pillow Cub. The Pillow Cub is designed for children in mind, and it pretty much looks like a Pillow Pet, only with a more robust rectangular shape. Similar to the Pillow Cube Pro, the Pillow Cub allows for rolling and moving during the night, primarily because it has a foldable design. Fold it for carrying and cuteness; unfold it for sleeping. 

All Pillow Cubs are 12 inches wide & 6 inches tall when folded and 24 inches wide & 3 inches tall when unfolded. The fun exterior designs can be removed for washing, leaving only the foam core behind. Pillow Cubs are $80, and you can choose from fun themes such as unicorns, sharks, sloths, dogs or bears. 

In addition to all of these pillow products, the brand also offers a range of pillowcases for all of its pillows, from your standard neutral tones to more fun options that play off the cube design. For example, turn your square cube into a stack of Belgian waffles or your rectangular Cube Pro into a stack of money.

Is the Pillow Cube Worth It?

Based on all of the above, is the Pillow Cube worth it? The jury is still out. Some reviewers say the Pillow Cube changed their life and gave them their best sleep ever, while others say it might not be worth all that cash. 

One reviewer at Slumber Yard said she was using a Casper Pillow previously and her first night using the Pillow Cube was difficult, primarily due to the cube’s small size (it’s literally only big enough for your head). 

However, after a few weeks of sleeping on the cube, she said she could see a big difference in her sleep quality. She woke up with less neck and head pain, felt more rested and felt more comfortable when sleeping on her side. She did note a few caveats, such as the fact that the pillow can only be used for side sleeping. Additionally, while the pillow’s cover can be washed, the pillow itself cannot.

An Apartment Therapy reviewer reported a similar experience, saying the pillow is “seriously comfortable, and I feel like my head is resting on a cushy cloud. Because I’m not repeatedly adjusting and readjusting my pillows throughout the night, I’m sleeping better than I have in months. I no longer arise from bed feeling sore and stiff, and I’m much more well rested…”

Many of the reviewers who were negative or on the fence were sure to point out that this is all because the Pillow Cube is best only for exclusive side sleepers, no other sleep position. If you’re someone who starts out on their side and then moves to their back or front, or vice versa, or even just a regular stomach sleeper or back sleeper, the Pillow Cube isn’t a good fit for you. It’s only comfortable if you use it as intended. (‘But,’ you ask, ‘what about the Pillow Cube Pro? Can’t you roll around with it?’ Kind of yes and kind of no. You can roll around, but you can only roll from one side to your other side for peak comfort.)

Some negative reviewers, though, were just plain unhappy with their experiences. In one review in Wirecutter, testers said the pillow gave them a headache and that they had to swap pillows in about 10 minutes. They also had issues with their mattresses being softer than their Pillow Cube, meaning they didn’t achieve that 90-degree angle that makes the Pillow Cube’s comfort possible. There were also complaints that the sizing (in terms of ordering a pillow according to one’s height) wasn’t perfect. 

Are There Alternatives?

Yes! There are alternatives to the Pillow Cube if you just don’t like the idea of sleeping on a square or if you think the general look of the cube isn’t going to blend in with your bedroom aesthetic. Plus, let’s face it, for those who do other things in bed beyond sleep — whether that be watching television, reading, cuddling, whatever — the cube isn’t comfy. It’s just not built for casual lounging like normal bed pillows are. 

You do have a few more traditional pillow alternatives, though. 

The Bear Pillow

The Bear Pillow

The Bear Pillow comes in at a similar price point as the Pillow Cube, but it’s rectangular and tall, with plenty of firm fluff to keep your neck at a horizontal angle no matter how you like to sleep. The pillow’s design boasts a proprietary Loft-X foam and Double Ice fabric. It’s also hypoallergenic and anti-microbial. Side sleepers, back sleepers, tummy sleepers and all-night-rollers all have good things to say about this pillow.

The Ghost Pillow

The Ghost Pillow

The Ghost Pillow is very similar, with that cooling technology and extra fluff and lift that allows for sleeping in all positions, but it also comes with a 101-night trial period, so you can really give it a long test run before you decide whether or not it’s right for you.

The Eli & Elm Side Sleeper Pillow

The Eli & Elm Side Sleeper Pillow

The Eli & Elm side sleeper pillow is unique in that it looks like a traditional pillow, but it’s curved in on one side, leaving an indented space where your shoulders and neck can slide in while sleeping on your side. This pillow, however, is one of the most expensive options on our list, at $120. 

Still Not Finding Comfort?

If you’ve tried every side-sleeper-specific pillow in the world and still haven’t found your perfect match, you may need to adjust more about your sleeping habits than simply your pillow. 

There’s nothing wrong with sleeping on your side. It actually comes with some health benefits, which is why sleepers have been sleeping on their sides for centuries. Sleeping on one’s side can reduce chronic pain, snoring and even gut health (via Healthline). However, as you likely already know, sleeping on your side without the right support can also result in headaches, neck pain and shoulder pain. 

For your best chance at a comfy sleep while sleeping on your side, Healthline recommends purchasing a medium-firm mattress and a firm pillow (and you’ll see that all of the options above are definitely on the firm side). Furthermore, to avoid neck pain, try to keep your chin pointed forward rather than tucking it down. Keep your arms and hands below your neck and, if needed, try adding an extra pillow between your knees, which can help with spine alignment. You can also bend your knees upward to help alleviate back pain.

Then, when you wake up in the morning, try some gentle stretches to help alleviate pain further and work out any knots or kinks that have developed during the night. 

The Final Verdict

What’s the final verdict on whether or not the Pillow Cube is worth your cash? Is this really the best pillow for you? 

If you’re an exclusive side sleeper, yes, the Pillow Cube is worth the money. You’ll quickly and easily remedy your sleeping woes with this one little purchase (and if you end up not liking it for whatever reason, you can always return it within 30 days).

If you’re not an exclusive side sleeper, no, the Pillow Cube is not worth your money.
