Query: Used it once and hated it!!!

Someone had told me about this pillow and how great it was, but when I got it I was very disappointed! When I first felt the pillow the material was very ruff, so I figured washing the cover would help, it didn't. The only way I can really explain the pillow is its loud and annoying. I would not get this pillow or any pillow off line because you can't feel it. Don't buy this and waste your money!!!
