"Also the chair came with a 12 year warranty. A couple months ago the pneumatic cylinder went out. I called a local Aeron deal and since I bought the chair from a authorized dealer, they sent somebody to my house and fixed it for free."

The seat pan on my Dad's chair (which he bought around 1997) broke a couple of times, at which point they simply replaced the entire chair.

He's been using it without complaint ever since.
