I was looking for a chair that would help me sit comfortably for long working hours and I wanted to make sure the chair helps me maintain a correct posture since I am tall and I didn't want any issues with my back or knee. Maxiims understood my need within 5 minutes over a phone call and suggested to me the chair that would suit all my needs. I am glad I went by their expert opinion. I couldn't have asked for a better chair. I can sit for long hours with absolutely no issue.
