Some of us never think about pillows. Even if you wake up with a sore neck etc. My chiropractor suggested this pillow for some neck and back pain I get from time to time and I am hooked.

Not only does this pillow prevent pain it makes me sleep like a little baby (drooling and all lol).
You fill it with water to your desired tension (I filled mine right up) and the water is surrounded by regular pillow material so it still feels soft.
I have never slept better. Claire and I are buying 2 more just for travelling.
