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

Shredded Memory Foam and Polyfiber Mix

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.

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 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.

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.

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.
