I work at a desk job where, on most days, I am sitting in front of a computer for about 8-1/2 hours a day. I have some posture problems and back pain that I was hopeful a kneeling chair would help with. I used the chair for a total of 3 days: the Monday after I received the chair, and the following Thursday and Friday.
