I have become a regular customer of Wayfair for household furnishings.  They have never disappointed me, and the most recent purchase has been no exception.  I have needed a new desk chair for quite some time, and finally took a day to try out every showroom in town and every ergonomic chair.  When I sat in the "Amia," I knew instantly that it was the one--it beat out all the competition.  Delivery was punctual, the item was as promised, the upholstery perfect, and I am very very happy.  I love this chair and every feature it advertises.  If you are in the market, I highly recommend this one by Steelcase, but there are several other in the line that are also excellent.  The Steelcase "Leap," for example, is very much like the "Amia,"  but a little heavier--probably perfect for a man's frame.  But finding the right chair really and truly requires the "toosh test."  Invest the time and try out all the top competitors--your research will pay off in the 'end.'
