I am an IT technician that is sitting at my desk about 60 to 80 percent of the day. I have a bad back and injured hip. The company I worked for would purchase a chair if a doctor note was provided. I would also have to find a chair that would be suitable for my issues. I worked with my chiropractor to find a chair that would be good for me and found information pertaininng this chair. After my company ordered the chair, I found that it made a difference. The constant motion would allow my hip stay flexible and the way the seat was designed kept my posture upright allowing for less pain. Not to mention the cost of the chair was less than chairs that were originally purchased. Others in my office are looking into getting these chairs as well. Great chair.
