I have been searching for a comfortable pillow for years; after using these for a full week my search continues. I sleep on my back and my side and this pillow is not comfortable for either position. There is too much fill inside making it very uncomfortable to sleep on my back. The pillow is somewhat more comfortable when I turn on my side because I can sort of punch it down to make it more compact. However, I am not keeping these pillows because they are just too over-stuffed!
