It works! Corrects the poor posture while sitting.
I purchased this product to help an employee with a pinched nerve. Unfortunately it is not a one size fits all. I decided to try out the lumbar support seat before I would send it back and after a few minutes of using it want to keep using it. My posture at the computer is terrible and so my back always hurts. This instantly corrected the poor posture and instantly relieved some stress in the back. I am happy with the seat. The only thing I think needs to improve is for it to fit different size bodies better.
