Does anyone sit on a computer chair with an all mesh back and bottom? Is it comfortable? Leather was the WORST idea. My current chair is a biohazard. If I put it out on the street I'd be taken downtown for attempted bio-terrorism. I was thinking of getting an all-mesh chair (or at the very least one with a mesh bottom) so...y'know...my asshole and back wouldn't sweat like crazy. I'm not a really sweaty guy, either. It's just, I presume, the leather not breathing. I've used fabric cleaner and just a week later it smells like a paper mill.
