hi molly,
what you've found to work for your neck sounds a lot like me, so i thought i'd share this. the neck pillow i got was from brookstone. it is some kind of squishy material inside (reminds me of my feather pillow the way it conforms to my body). it came with a removable soft cover (that really comfy soft material they are using for robes and blankets and everything now). i love this neck pillow so i bought another. before that i tried a few that i hated.
how do you like your memory foam one?
