I don't think there is one chair at a fifth of the price or even half the price that is as adjustable. Please post one if true, as I'd love to have such a discounted feature.
I can’t really get you specifics. Three years ago when my wife and I were chair shopping after an office deco/design change, I came across a number of highly adjustable chairs in the “less than $600” price point that we were shopping during that time (We share the office and were buying two). What was important to us was they fit a specific design aesthetic (Aerons did not), that they were the same chair (for design symmetry), and that they were comfortable and adjustable to our individual needs. We ended up with 6-way adjustable chairs that met our needs and came in around $550 each. Because of our criteria, it took the better part of a mo th of active shopping to find our unicorn.
Google tells me Aerons have 8-ways of adjustability. The missing adjustability I don’t have are arm height and tilt. I don’t miss it. And if I did, it’s not worth the extra grand it would take to get it.
I gave them a quality evaluation and have had occasion to sit in them for long periods at client sites.
I am all for spending for quality and generally am a BIFL type consumer, but these chairs just don’t carry the value for me.
