I'm passionate about quality sleep. I spent months testing pillows, and I'm reader-supported through purchases on Amazon.

In-depth Comparison (2024): Coop Eden Pillow vs. 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 an in-depth comparison of the Coop Eden Pillow and Pillow Cube Pro Pillow.

The Coop Home Goods Eden Pillow is an adjustable pillow similar to the Saybrook pillow. I really enjoy the sleep experience on the Coop at the start of the night, but it does have a few flaws that hold it back, including the way the polyester filling is tangled together inside the filling, the overall dominant feel of the polyester filling, and memory foam that doesn't feel like memory foam to me.

The Coop Eden Pillow is adjustable, which allows it to accommodate multiple sleep positions and body types.

The pillow is adjustable with shredded memory foam and polyester fiber inside. It arrives in a box with extra filling, which is a nice touch, though it comes overstuffed already. I doubt anyone would be adding additional filing. Personally, I took out about a quarter of the filling before sleeping on mine. The ability to micro-adjust the pillow loft to the perfect height gives this pillow a massive advantage over other pillows in contention without this feature. The Coop Eden Pillow is the higher priced pillow that Coop offers. They also offer the Coop Original pillow, which does not come with silicone gel, according to the Coop website.

The polyester fiber is different in the Coop pillow compared to the Saybrook pillow. The fibers are long and tangled throughout the pillow. There is also more polyester fiber in comparison. The result is that taking out filling from the Coop pillow requires ripping out chunks of entangled polyester fiber, similar to ripping apart large cotton balls. For the Coop Eden Pillow that I have, after I remove some filling, I have to shake the pillow vigorously in order to spread everything evenly again because the filling left inside the pillow is still tangled together. The experience has unnecessary friction.

The Coop Eden filling has more polyester fiber relative to the Saybrook Lion Down Alternative filling. Overall, it sleeps more like a polyester pillow for me.

I am underwhelmed by the quality of the foam. When I squeeze the foam between my fingers, it just seems like regular foam to me instead of memory foam. Instead of a slow motion compression, the foam collapses in real time, and I can visibly tell that the foam has looser air bubbles. The Coop foam brings to mind the foam used on Walkman over-the-ear headphones in the 80's or the foam of a sponge. As a result, my experience is that the foam provides less support compared to other memory foam pillows that I've tried. I find that my Coop pillow feels flatter by morning, and I don't feel as supported as I would like. Unfortunately, adding more filling in would make the pillow feel too lofty at the start of the night, so that wouldn't be a good solution to the problem. On the plus side, I do enjoy using the Coop pillow for stomach-sleeping.

Notice the larger air bubbles shown here in the Coop foam.

Because the proportion of polyester fibers is higher and because of the feel of the foam, the pillow overall sleeps more like a polyester pillow in my opinion. If you're looking for a polyester pillow, I would recommend the Coop Eden Pillow since it is adjustable. However, if you're looking for the feel of a memory foam pillow, then I'd recommend considering the other options.

  • Premium price
  • Hard to put case back on

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.

Our neck and shoulders don't connect at right angles.

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.

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.

Picking the right pillow can be important. I did all the research here to make the process easier. I hope that this blog helps you as you make your decision.
