I tried this chair at a tradeshow and thought they were out of their minds trying to sell this chair for this much. I did some research and found that the top end chairs are well over $10K. Nonetheless after I tried other chairs, hands down this chair had the best massage on the back, The massage for the legs and arms were similar to others but the massage sold me. It was a big purchase but I can honestly say it's worth it. If you call to buy a chair, ask for Tuan. Really knowledgeable and flexable.
