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.
