I find the pillow very comfortable! However, when I first opened it, I noticed the strong chemical odor. I have allergies and cannot believe that an odor that strong would be good for anyone. I am giving it a week to see if the odor goes away. If not, it goes into one of my guest bedrooms. (I have not submitted my review earlier because I have been out of town and just started using the pillow.)
It took about week or so to get used to. But after that would not want to be without it! So much better sleep and comfort all night long. No neck ache anymore!
