Finely shredded memory foam
This arrived well packaged with multiple layers of compression. It contained finely shredded blue memory foam. It was soft and compressable. There was enough to fill a small pillow, I had to also use the other memory foam I had on hand to fill the dog bed I was making. I can't speak to the durability yet, but it seems to be the same texture as the other memory foam I've worked with, so I expect it to hold up fine. Overall, I would order again.

Perfect for the neck
Color: Black and White
Excellent pillow. After using it for about 3 weeks I can truly say my morning neck pains are totally gone. Took some getting used to but it was worth it. Very comfortable and seems to be well made. Highly recommend.

Good pillow
Color: Black and White
Very comfortable and good quality. The only reason I am giving it four stars is I wish it was a little bigger. I’m a man and when I wrap my arms around the pillow they aren’t supported fully.

Great pillow
Color: Black and White
This has helped with my neck issues. It does stay cool and keeps me from sweating like my old one, but I do wish it stayed cold.
