When I saw these satin pillow covers I immediately thought of the contour pillows I have and ordered them. They fit the contour pillows perfectly and stay in place with the zipper. The first thing I noticed in the morning was that my hair was not all messed up even though I do a lot of turning. I also noticed my face to look better and smoother. I have given part of my covers to several people to try and they are also amazed, they work great on regular pillows too. I hope that you will keep them in stock, they are excellent in every way. Thank you Overstock.
