I love this pillow and have gotten so use to it that I can't sleep without it. I bought my first one about 7 years ago and was told it should last a few years then I would need a new one. I finally decided maybe I should get a new one in case my old one was wearing out... I should not have wasted the money. I can not tell any difference between my old one and my new one. These are awesome pillows and they last!
