In-depth Comparison (2024): MyPillow Premium Series Pillow vs. Pillow Cube Pro Pillow

Shredded Foam

The MyPillow Premium Series Pillow dominates hours of late-night commercials, but the pillow disappoints in person. MyPillow uses large chunks of shredded foam with an elastic nature. As a result, the pillow is lumpy and bouncy. I would not recommend the MyPillow due to these comfort issues and the lack of adjustability.

The MyPillow doesn't come with a separate removable cover, and the pillow encasing cannot be unzipped, which means the pillow loft can't be adjusted. Instead, it comes in four different loft levels coded as colors, in increasing order of filling level: White, Yellow, Green, and Blue. I ordered the Green fill level after using the selection tool on the MyPillow site.

I measure the loft at about 7.5 inches, and the fill is pretty firm. The pillow barely compresses when I lay my head down passively. The loft is slightly too high for my comfort level when I sleep on my side, though I don't mind when I sleep on my back. The Green level pillow is too thick and firm for stomach-sleepers, but the White or Yellow fill level might work for that purpose. Because the pillow can't be adjusted, sleepers have to hope that one of the four fill levels happens to fit perfectly for them and hope that they choose the correct one on the first try.

My main issue with the pillow, though, is the nature of the shredded foam filling. The Saybrook and Coop pillows use softer foam and mix the foam with polyester fibers, so those pillows don't feel lumpy to me. On the other hand, MyPillow uses large chunks of firm foam without any polyester fiber, so the pillow is noticeably lumpy. The pieces of foam also have an elastic bounce. The MyPillow reminds me of a bag of packing peanuts in the firmness, the lumpiness, and the slight elasticity. When I shift my weight on the pillow, I can feel the elasticity of the foam. The jiggling of the elastic foam can be distracting as I try to fall asleep.

Based on the MyPillow website, it looks like there are two main differences between the MyPillow Classic Series and MyPillow Premium Series. First, the MyPillow Premium has a shorter width, coming in at 16.5 inches wide compared to the 18.5 inches of the MyPillow Classic. I would not expect this difference to affect my sleeping experience on the MyPillow. Second, the MyPillow Premium comes in four loft levels (White, Yellow, Green, and Blue), while the MyPillow Classic only comes in two (Medium and Firm). This is also not a difference that would affect my review since my main complaint is the lumpiness and bounciness.

Solid Memory Foam

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.

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.

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.

Update (1 year later): I tried the newest version of the Pillow Cube Pro, and it seems they updated the firmness of the foam from much too firm to medium firm. They also updated the zipper opening for the cover to wrap around. These are welcome updates for this pillow. Unfortunately, at the new firmness level, the pillow is now too thin when I lay my head down because it has more give. The pillow went from angling my head upward to angling it downward. They advertise that side-sleepers need a pillow that fits the shoulder gap, but this pillow does not solve the problem. If you are a side-sleeper, you need a pillow that is adjustable to fit your shoulder gap. Adding a right angle does not solve anything.
