I need a new office chair and desk or I will end up a hunchback. These chairs are the ones I've read about most. Does anyone have comments about one or the other? I'm looking at the knoll price list and there are so many options... I'm gonna stop by the knoll store in montreal to check it out, but I doubt they'll have a ton of differently configured chairs there. Am I missing any other chairs? I want quality that will last and it doesn't hurt if it's attractive (which some people think detracts from the aeron). I sit in this thing for hours so ergonomics is a prime concern. As for the desk, I'm debating between a high-end ergonomic computer desk or something that's more interesting in terms of design. The computer is a tower that can go on the ground under it or beside it. The only constraint here is that it needs to have a big enough surface for 2 24" monitors and is at a comfortable height for the use of keyboard and mouse. It would be nice if I could get something that was both attractive and ergonomic. I hate cheap materials. It doesn't need to have tons of shelves or drawers. Every desk I've ever owned has been ugly. If anyone has suggestions, I'd love to hear them. Then again, I might go really cheap, as I feel my design preferences are shifting, and I want my furniture to form a cohesive whole, if possible.
