It's like shoes, everyone's ass is different.
My Aeron chair is 6 or so years old and the most comfortable chair I have ever used. Everyone who has tried it agrees. You can't go wrong investing on one; they'll last for a long, long time.
I figured if it would last 5-7 years it would be a good investment. My current chair squeaks and cracks like an old house every time I move and it is only like a year old. Do they come pre-assembled or do you have to build it yourself?

The closest place to me that sells them, according to Herman Miller's website is a little over 2 hours away (each way). I'm kinda weary of just straight up ordering a chair that is that expensive off the internet without testing one first.
