I love this office chair. I have been fighting back pain for about a year or so, and after one night of using this, my back pain is so slight. It is ergonomically built so that you don't slouch in it. Every morning I am really grateful that I choose this chair. I am a petite woman 5'2" and small framed, so this might have a different effect for others that are a lot taller than I am. I love it.
