Kim,
I love my zero gravity chair. I was able to sit in it comfortably for hours, even sleep in it. It took all the weight off my lower back. I no longer need it, but I won't part with it. Guests & family members also love it. You can find them online, even generic versions. I've seen them in stores. Email me if you want to know where you can find one. When my back was hurting (prior to ADR sugery) it was my favorite possession.
