an aeron chair costs about $2000 dollars (give or take). The construction is sturdy, so i expect it to last at least 10 years, if not 20 (you take care of it etc).
So the amortized cost is some 100-200 dollars a year for an excellent chair. If you buy a crappy chair, i bet that the cushion starts failing after a year or so of constant sitting. So you'd probably replace it yearly, or suffer a bad chair for a few years before replacing.
I bet that most people would choose an excellent chair, if they could guarantee themselves the 10 yrs of good operation and comfort.
