I have been suffering from sciatica and hip bursitis for months. I work from home and sit all day. After shots, steroids, standing up at my desk and stretching exercises did not help, I began to notice that I started feeling better over the weekend, when I had not been sitting at my desk. I read the reviews on this chair and decided to give it a try. It arrived in the morning and it was put together very quickly. I was sitting in the chair by 10am. By that afternoon my pain had decreased significantly. I am so happy with this chair! I did not need the foot rest but since I was dealing with pain, I now roll my chair from my office to the living room and use it to watch TV. So thankful that I chose this chair.
