Pillow Cube Overview

Sleep Cube Overview

According to the company’s website, Pillow Cube began as a Kickstarter campaign and has since grown into a “sleeping revolution.”

The maker of this pillow wanted to give people the opportunity to sleep better, so they designed an ergonomically contoured pillow that works with your body instead of against it.

The founder of Pillow Cube was a self-proclaimed “sleepless insomniac” who struggled to rest for years after developing a sleep disorder.

The makers of Pillow Cube wanted to create a pillow that people could use to sleep better and created Pillow Cube.


What is a Pillow Cube?

What is Pillow Cube

Pillow Cube is a unique, rectangular-shaped bed pillow for side sleepers who have a hard time sleeping at night due to neck and back pain.

The Pillow Cube has a soft and squishy feel on the top but firm support underneath. It’s made of 100% polyester fiber, so it doesn’t hold in heat like memory foam pillows do, which makes it ideal for hot sleepers or those who tend to overheat while they sleep.


Machine Washable Cover

One of the main perks that drew us towards this pillow is that it can easily be cleaned and maintained by tossing it in the wash.

After washing our pillowcase multiple times over two weeks, we found that there was no sign of residue left behind from detergents or bleaching agents, which is pretty impressive considering most pillows come with a non-removable cover.

The case is made from 100% polyester, making it soft to the touch and hypoallergenic, so if you have sensitive skin, this is a product you will want to consider.

Now don’t get us wrong, most pillows are easy to clean, but the best part about the Pillow Cube is that you won’t need to replace it anytime soon since it can last for years without any issues.



The makers of Pillow Cube claim it works to contour around your head and neck because of its shape. This provides the optimal support you need as a side sleeper without adding pressure points that can lead to pain through the night.

It also helps reduce the likelihood of snoring. Side sleepers are known to have an increased risk of obstructive sleep apnea, so anything that makes it easier for you to breathe peacefully should be a huge plus.


Temperature Control

It’s the only pillow made with micro-pillows, so it won’t hold heat or become hot to the touch like memory foam does, which makes this rectangle pillow great for sleeping hot.

This rectangular pillow has special channels that allow airflow to keep you cool when you sleep to prevent overheating and allow your body temperature to regulate throughout the night.



This pillow is not only made with quality materials but also considers their impact on the environment. The micro-gel memory foam used in many of its products has been clinically approved as ILD CertiPUR-US certified.

This means they are made without harmful, which provides an improved breathing environment.

Since the memory foam is free of carcinogens, asbestos, phthalates, or PBDE flame retardants, it’s ideal if you care about the environment and prefer not to sleep on harmful toxins.

The fibers in the Pillow Cube are antimicrobial and hypoallergenic to prevent allergies or irritants from forming inside the pillow. Plus, you won’t have to worry about your face getting stuck to a sweaty memory foam surface when you wake up!


Affordable Price Point

Overall, this pillow is priced very low compared to other pillows available in its category. However, we found that the Pillow Cube still held its shape better than many higher-cost pillows on the market, so if you’re looking for an affordable product with great quality, we would recommend giving this one a try.

Let’s dive into the different Pillow Cube offerings.

Sidekick (Classic Pillow Cube)

The Sidekick is the original cube offered by Pillow Cube. Of the Pillow Cube offerings, this is the smaller size. The square pillow comes in two different firmness options. We tested the medium-firm one, which is not 100% firm but gives you a good amount of support when placed under your head (far better than your average pillow).

The pillowcase it comes with is made from polyester microfiber, so it’s soft and breathable to keep you cool all night long.

It’s machine washable, so you can easily clean it to maintain the Pillow Cube’s hygiene. In addition, its shell is made from 100% polyester fiber that doesn’t contain any harmful toxins, allergens, or irritants.

What separates the Pillow Cube Sidekick from your traditional pillows is its shape – it’s a unique rectangular-shaped pillow designed for side sleepers. This unique design allows you to rest your head and neck in the correct position without added stress or discomfort.

We’ll admit, the first night sleeping with the Pillow Cube was a bit weird as it is totally different than the conventional pillows we were used to. After a few nights of sleep with the Pillow Cube Sidekick, we felt well-rested and refreshed for the morning. There was no stiffness in our neck, and we were able to fall into a deep sleep without tossing and turning too much throughout the night.

Pillow Cube Fluffy

Due to its design, it’s not as fluffy or soft compared to a memory foam pillow but provides a medium firmness that wouldn’t be difficult for most people to sleep on comfortably.

The Pillow Cube Sidekick is great for sleeping on their sides because it does not add any pressure points to the neck.

It also reduces snoring. Side sleepers are known to have an increased risk of obstructive sleep apnea, so anything that makes it easier for you to breathe peacefully should be a huge plus.

Pillow Cube Pro

Pillow Cube Pro 

The main difference between the Sidekick and Pillow Cube Pro is the pillow size. The Pillow Cube Pro is longer and thicker, making it an ideal option for taller people.

It’s made with the same design idea as the  Sidekick (with micro-pillows inside to prevent heat retention); however, the gel material inside the pillow uses patented technology that increases airflow to regulate body temperature throughout the night.

This rectangular pillow also provides optimal neck support to reduce pressure points while giving you a comfortable sleep all night long.

Pillow Cube Pro Rectangle

The Pillow Cube Pro comes in three different density options, so you can choose how soft or firm you would prefer your pillow to be. After testing out this pillow, we fell in love with its excellent support while being soft against our heads at the same time.

The gel memory foam was also cooling to the touch and prevented overheating during sleep.

It’s worth mentioning that you will need to give the Pillow Cube Pro a good 20 minutes or so for it to fully expand before sleeping on it. However, once this pillow has been opened up, it holds its shape better than other pillows we’ve tested in the past.

We would recommend this firmness option if you prefer a medium support pillow that is not too soft but provides great comfort when using it all night.

Overall, we found this to be a comfortable pillow and worked well when placed under our necks.

What’s the Best Way to Use a Pillow Cube?

Pillow Cube Classic Cube

Pillow Cube is designed specifically for side sleepers. For stomach sleepers or back sleepers, this might not be the ideal pillow for you.

Side sleeping is generally better for snoring and obstructive sleep apnea, which are problems that can affect those who mostly prefer sleeping on their sides.

It also helps neck and spinal alignment so it can reduce pain by supporting your head instead of putting pressure where there isn’t any support already present.

If you do choose to use this as a top layer pillow because of its squishy feel, it won’t be as supportive as a memory foam option, but if you want to invest in a solid pillow, this should be your top choice.

Depending on where you prefer additional support, the Pillow Cube works best for side sleepers if placed under the neck or between the knees. It provides good compression when using directly on your body but not as much lift as other memory foam options.

Overall, we found this pillow to work well for back and side sleeping, especially because of its firm shape and design.
