There are a few threads here where people have discussed the pillow issue, so it's worth having a look through those. [Edit: somehow I missed Strider's post

It's a personal thing though - some people love what doesn't work for other people. I've tried a lot of options over the years, as a side sleeper. In the end I went for this one, and I'm a very happy camper. Very light, at around 37 gm, cradles my head well.
