Aeron Chair, all ready to buy, but...

[ebaudry]

OK, thanks everyone for the feedback, I'm now definitely going to buy one of these chairs. I was all set to buy a "basic" one for about $475, then I noticed some options that intrigue me.

PostureFit: I want one, but I have to think the chair offers good support without one? Do you have one and think its necessary? Did you not buy it, but wish you had? If you don't have the PostureFit, do you still find you get good support?

Forward Tilt and Tilt Limiter: Please explain... What are these for practically speaking.

Leather Arms: Worth $60?

Warranty: Some seller's are offering the remainder of the 12 year, other sellers are offering a warranty through their own distribution company (typically 1-3 years). Others are offering no warranty at all. Thoughts on the warranty? Should I get one? If I resell this chair someday, is the lack of warranty going to hurt do you think?

Thank for the input, this is a huge expense and decision for me.
