In-depth Review (2022): Pillow Cube Pro Pillow

I tested 14 different pillows over the course of six months. I slept on each pillow for at least five nights each. I rated each pillow based on how comfortable it was to sleep on over an extended period of time, whether or not the construction seemed high quality to me, and my take on suitability for different body types and sleep positions. Here is my in-depth review of the Pillow Cube Pro Pillow.

I do not like sleeping on the Pillow Cube Pro Pillow, and I would not consider it worth purchasing again. The Pillow Cube advertises its unique shape (a cube or a rectangular box in the case of the Pro Pillow), but in my opinion, there is a reason why other pillows aren't shaped like a box, and it's not because no one else realized it was possible. Instead, it's because our necks and shoulders don't connect in sharp angles, so regular memory foam pillows have a curve instead of an edge. When I use the Pillow Cube, the sharp angle digs into my neck.

The Pillow Cube Pro Pillow is a solid memory foam pillow in the shape of a rectangular box. The pillow is available in a 4-inch, 5-inch, and 6-inch size. The website, as of my time of purchase, advertises that the different sizes allow the pillow to perfectly fit the pillow gap, but the website also recommends the 5-inch option for everyone between 5'4" and 6'3". Since that is a wide range of heights and body types, I was already skeptical that the pillow would fit perfectly. As expected, now that I've tried the pillow, I can confirm that the 5-inch pillow doesn't fit my shoulder gap perfectly. Though the 5-inch starting loft is a relatively low starting loft, because the foam is incredibly firm and doesn't compress when I lay my head on it, the effective loft of the pillow feels relatively thick. My neck ends up angled uncomfortably when side-sleeping. In general, the 1-inch gap between sizes is the same as the size difference between a size 6 shoe and a size 9 shoe (for both men and women), so I would expect many people won't be able to find a perfect fit. Instead, for side-sleepers, I recommend looking at an adjustable pillow like the Saybrook or Coop pillows, which can be micro-adjusted to the perfect fit.

The corners of the Pillow Cube pillow dig into my neck when I sleep on my back. The design is meant to benefit side-sleepers, but I don't feel any advantage of having a corner while sleeping on my side either. I'd prefer for the corner to be rounded out, which would result in the shape of a normal memory foam pillow.

I consider the shape of the pillow a downside as well. The boxy shape makes the pillow worse for back-sleeping and stomach-sleeping because I can feel the corners dig into my neck. Though the pillow is designed for side-sleepers, the way the pillow affects back-sleepers and stomach-sleepers is worth noting because many people switch among the positions even if they favor side-sleeping. Even for side-sleeping, the edges don't improve the experience for me. Instead, I would prefer the corners to be rounded out, which would result in the same shape as a normal memory foam pillow.

The Pillow Cube foam feels much firmer than the Weekender memory foam, which already feels much firmer than the Tempur-Pedic memory foam. I consider the Tempur-Pedic memory foam extra soft, the Weekender memory foam extra firm, and the Pillow Cube memory foam off-the-charts-firm, applying unwanted pressure against my ear and jaw when I use it. The Pillow Cube has a removable zippered cover, and taking it off reveals the grey foam inside. The foam reminds me of the industrial foam used to pad furniture in moving trucks or the foam used in gymnasiums.

The Pillow Cube foam reminds me of the industrial foam used for furniture pads in moving trucks or the foam in gymnasiums. Unlike the Weekender memory foam, the Pillow Cube memory foam is not ventilated.

Putting the cover back on is a daunting challenge. Imagine the difficulty of fitting a duvet cover on a duvet. The corners are always annoying to fit into the cover. Now imagine there are eight corners instead of four corners, as well as eight edges that also need to fit into the proper place in the cover. The most difficult part, though, is getting the foam into the zipper opening in the first place. The zipper sits along the long edge of the pillow, and even though the long edge measures 24 inches, I measure the zipper opening at only 19 inches in length. As a result, the challenge is to fit an ultra firm 24 inch by 12 inch by 5 inch block of foam through a one-dimensional line-shaped zipper opening that measures 19 inches long.

If you want a pillow that is as firm as possible, then the Pillow Cube might be an option, but I would recommend trying the Weekender first because the Weekender memory foam is already very firm. If you want a pillow designed for side-sleepers, I would recommend looking at an adjustable pillow like Saybrook or Coop.

How Does The Pillow Cube Pro Pillow Compare?

Comparing pillows can be difficult because reviews out there are often written by people who've only tried one pillow. What does it mean for a pillow to be soft or firm if there's no point of comparison? How do you know if one pillow is truly better than another? Which pillow is right for your body type and sleep position?

My experience systematically trying each of 14 pillows provides some insight into how to compare the pillows. You can read my comparisons of each pair of pillows in the links below, or you can read the full review with all the pillows as well as my pick for the best pillow.
