I spend a fair amount of time sitting on my ass in front of my computer, and I've gotten alot of time between two chairs (one at my dorm, one at home). However, both now seems to have an odor to them. The upholstery...seems to have taken up the smell of years of sweat, flatulence and other stuff that seditard human generates over a period of a few years of use and it smells kinda rank when you first plop down.
