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. Wondersleep 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 Wondersleep 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.

On paper, the Wondersleep Premium Adjustable Pillow should be similar to the Saybrook and Coop pillows: it has shredded memory foam and polyester filling. However, that's where the similarities end. I selected this candidate because it was much cheaper than the other pillows while sporting the same reported features. I wanted to see what the difference was in person. Unfortunately, the pillow case quality, the adjustability, and the filling comfort level don't match up in my opinion.

The Wondersleep pillow has soft filling and a thin profile.

Immediately upon unpacking, I notice the pillow has much less filling compared to other pillows and is very thin. The thinness of the pillow defeats the purpose of the adjustability because it won't be in the loft range many people need. The loft might be okay for stomach sleepers who appreciate a thinner pillow. Though the initial loft measures at 6 inches, the pillow compresses a third of the way down for me when I lie down due to the softness.

The dominant feeling for me in the Wondersleep filling is the polyester fiber.

The sensation of the Wondersleep pillow fill is dominated by polyester fiber for me, with pieces of shredded memory foam buried throughout. The memory foam feels stiff, not just firm, as if it had been left out in the sun too long. The pillow reminds me of clumps of cattail fluff in the wild: mostly soft and fluffy but with random bits of hard seeds (or in this case, memory foam) inside.

Some pieces of foam in the Wondersleep pillow look yellowed.

Though many shredded memory foam pillows under $50 can look similar to the Saybrook and Coop pillows on paper, I recommend investing more to get the higher quality construction and better filling found in the top picks.

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.
