Inconsistent
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Ive ordered two different batches of these pillows, the first was a 2 pack, the second batch was a 4 pack. The pillows that came in the 2 pack have a different quality to them. The memory foam feels thicker, takes long to depress and to spring back to form. It offers more resistance, a heavier odor (at the start), and was the pillow that I fell in love with. Things changed when I ordered the 4 pack a couple months later. There was an inconsistency between the foam in these two different batches. both sets of pillows are comfortable. The first batch being firmer means I had to remove more foam before it became comfortable but the 2nd batch being more springy, I was able to keep all the foam inside. I docked a couple stars because I’m not able to provide a consistent experience with these pillows across all three beds in my home.
If you need a pillow, order a set and be happy. If you want a bunch of memory foam pillows throughout your house, maybe look elsewhere as these may not all be identical.

Very cool and comfortable pillows. Great value.
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
These pillows are everything described on the site. They do retain shape and don’t flatten out after sleeping all night. They are nice and clean looking and comfortable. The fit on my king size bed is perfect cause I prefer the size to king size. Haven’t had to wash them yet but I have had other pillows with the same material inside and the wash ability is great.

Great pillow
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
The pillows feel great. Being able to remove portions of the interior allowed me and my wife to have a perfect fit. They do stay cool which seems to have helped with my restlessness.

Better then the fake down style pillows
These shredded memory foam pillows are really comfortable. They’re soft but still supportive, and I like that you can adjust the fill to get the firmness just right. They don’t go flat easily and hold their shape well through the night. Definitely a nice upgrade if you want something more customizable than a regular pillow.
