Query: Almost Perfect!

This thing works like magic and puts decent pressure on the sides of your spine gently aligning. I didn't give it a 5 star only because: A) I wish it was up a bit higher, I'd like to get a little more pressure, B) It doesn't hit all the parts of your back without having to use pillows to support other areas, and C) there's nothing for the neck which would be a great addition.All in all I would recommend this to anyone. I have had to go to the chiropractor less and it has payed for itself. Now only if I can find something for my neck!
