Why does everyone buy Aeron chairs for programmers?
kaiserama: I personally like my Aeron chair for 2 reasons.  1, because of it's mesh material.  I can sit in it for extended periods of time and not have much fatigue or get sweaty like I can with some of those pleather chairs that you have to assemble when you get them home.  2, for the many many number of ways you can adjust the chair.  I'm curious if the ones you've been sitting on are the basic model or have the lumbar, arm adjustments, etc.  Also they come in 3 different sizes and getting the right sized model is actually pretty important.I also find them much more comfortable to sit in but this could be because I have a medium sized frame and because I prefer sitting leaning back.Either way like noodle said, it doesn't really matter what anyone else says, if you don't like the aeron skip it.  We're all different and have different tastes.Cheers!
