Today on my way home from the bus stop, I found two chairs on wheels left by someone's garbage. They looked alright, and I wasn't too far from home, so I took them home with me. It was challenging, wrangling two chairs a distance of 3 or 4 blocks, but well worth it. One of the chairs is an office chair that I can lean back in. This is a huge improvement over the wooden chair I was using before, as I could never really relax in that chair. This one, though, I can lean back and relax in.
The other chair is upholstered in like, leather or pleather, and has round rivets. It's okay to sit in, too, but nowhere near as comfy as the other one.
Anyway, now I have a couple spare chairs in the apartment for those rare occasions I have friends visiting.
