[Tangurena]

I am obese [1]. When I sit in one of those cheapy ($150 or so) office chairs from the office stores, I find that the gas cylinders last about 6 months before my fat a@@ squeezes the gas out of them. Since they're cheap imports, the only way to get a replacement gas cylinder is to buy a new chair. So I was spending $250-350/year on office chairs at home.

I've had my Aeron for 4 years now. No new cylinders. So the $800 I spent more than paid for itself. If I had stayed using office chairs, I'd have spent more than $1k on them.

Notes:

1 - Getting run over by a car, and being unable to be as physically active as I used to be didn't help.
