"During my 30 years in physical therapy and ergonomics I have evaluated many chairs. Most are difficult to adjust and were very expensive for most budgets. Our objective is to bring to the ergonomic chair market a reasonably priced, easy to adjust and ergonomically correct chair. After several years of evaluation and trials, we have come up with what I believe is the best ergonomic office chair at any price. Best of all it can be customized for all sizes and shapes of clients."
