I'm not sure if I am up for buying a used office chair.  Having worked in many offices, I have seen what the human body can leave behind in a chair.  I remember inspecting a chair after a particularly oily fellow employee left.  There was, like, a dried crust on the arm rests.  My wife calls it body gravy.  Some things you can just never scrub clean.

I own one of these. I love it, but the mesh on the bottom is like an exfoliating luffa texture. The assembly directly below that conveniently collects everything that slowly gets turned to dust, be it pants, blankets, or dead skin.
