I've had a Herman Miller Aeron chair for several years, and haven't had any complaints, but I've seen in the comments for that review that not everyone is as big of a fan. Well, for those who want an upgrade, here's perhaps the ultimate luxury option when it comes to ergonomic computer chairs:
It sounds--and looks--like something out of a futuristic science fiction movie (and I'm not sure if it would go with my home office decor), but I'd love to try one out.
"Created by a group of medical researchers studying spinal cord injury, the Gravitonus ergonomic workstation comes with an on-board computer which constantly analyses body position, measures local temperature and pressure for different body parts and gently rotates the frame accordingly.
Currently being adapted for quadriplegics by means of an alternative computer control system (ACCS) which places a control unit in the mouth to do all of the work and allow for breathing, drinking, talking, smoking at the same time." ~ SafeComputerTips (see the rest of their blog post for a lot of other nifty ergonomic chairs too).

Whether you're suffering from repetitive stress injuries, back pain, or just want to have a healthy office environment, a good chair is a must. This is especially true for writers, programmers, and other folks who spend the majority of the work day at the computer.
I was over at someone's place the other day, and they have a kneeling chair, so I was able to try it out. He is an avid computer gamer (read: oh, I forgot to go to bed last night because my guild was on a dungeon raid...) who logs 100 hours or more at the keyboard (he has a computer job in addition to his gaming addiction), and his old chair (an Office Depot special) wasn't cutting it. Since he wasn't able to afford something like the Aeron (this is the chair I have, and you can read my review at the appropriately named
