Ha, I have an Aeron chair at work and guess what, its not that great. I still get back pain sitting in it all day. I did not even notice it was one for about a month after I started. Those chairs are mostly hype. Many studies (and my personal experience) shows that the act of sitting on your ass all day is not good for you. Spending $700 on a chair will not fix the fundamental problem. I don't know how to improve the situation, except maybe having kids standing and using desks at arm level, but I don't think buying new chairs will help anyone except the furniture salesmen.
