They are better than a bad chair, but there are definitely decent chairs for less. Also, somebody at my shop had an Aeron (after suffering a lot of ergonomic-induced damage - folks, never work through the pain) and the webbing actually "wore out" (as in, developed a hole) after only a couple of years. We did get it replaced without charge after a short argument but when you pay that kind of money for a chair you don't expect that to happen. If I were thinking of dropping a grand on a chair, I'd be looking at the humanscale chairs. Admittedly that is partly because I prefer their aesthetics. Anyway in my experience the number one criterion for a hacker chair is adjustable armrests - adjustable both in height and in width. You can get one of those for a lot less money. The rest of the notable improvements come from other ergonomic changes depending on the problem - for example in my case, my most important mod is to use a very small keyboard in order to minimise the reach to the mouse.
