billy- I sleep with a microbead pillow. Its worked well for me for about 3 years now!! What I like about it is the versatility- side or back sleep- I'm all over the place and this works with me.

Jo- I guess I can't recommend this for you- it makes a little bit of a sound... not quite crunchy like a buckwheat- but a sound nonetheless

This is not exactly what I use but I'm sure it is comprable>>>
