In-depth Comparison (2024): Tempur-Pedic Tempur-Cloud Pillow vs. Pillow Cube Pro Pillow

Solid Memory Foam

The Tempur-Pedic Tempur-Cloud Pillow is a solid memory foam pillow, which means the loft isn't adjustable. The Tempur-Pedic memory foam is also incredibly soft. For side-sleepers and back-sleepers, this memory foam will likely be too soft in my opinion. For stomach sleepers, who might prefer a thinner and softer pillow, the Tempur-Pedic works perfectly.

The quality of the memory foam is noticeable. When compressed all the way down, the Tempur-Pedic memory foam takes about 3 seconds to bounce back to the original shape, as if it were bouncing back in slow motion.

The foam is much softer compared to the Weekender and Pillow Cube, which are also solid memory foam pillows. I measure all three of these solid memory foam pillows at a 5-inch starting loft. When I lay my head down, the Tempur-Pedic compresses halfway while the Weekender compresses only slightly and the Pillow Cube barely has any noticeable compression, so the Tempur-Pedic ends up effectively thinner. The compression provides a very comfortable sinking feeling for people who enjoy that aspect of a pillow.

I've slept on the Tempur-Pedic pillow in all three positions. As a side-sleeper and back-sleeper, this pillow does not provide enough support for my preferences. My head just sinks down. However, this pillow feels like magic when sleeping on my stomach. I usually hug the pillow vertically so that half my body is on top of the pillow. The Tempur-Pedic will compress more for my body than my head, which is lighter, and the result is a very comfortable incline.

The pillow has a removable cover that feels well-constructed. Where the Weekender and Pillow Cube covers are thin by comparison, the Tempur-Pedic pillow cover is best described as substantial. Based on the feel of the memory foam and the feel of the pillow cover, I'd consider the Tempur-Pedic to have a higher quality construction compared to the Weekender and Pillow Cube.

I highly recommend this option for stomach sleepers. Side-sleepers and back-sleepers, though, need to be aware that this pillow won't have the support they might expect. I see mixed reviews for this pillow, and I suspect it's because the five-star reviews are more likely to be stomach sleepers who prefer a thinner pillow while the one-star reviews are more likely to be side-sleepers and back-sleepers.

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.
