In-depth Review (2022): 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 my in-depth review of the Wondersleep Pillow.

Where Does the Wondersleep Pillow Rank?

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.

How Does The Wondersleep 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.
