Yeah, I know. Nitpicking is one of my hobbies (and boy do the monkeys love it

) so I can understand why a little detail might derail your enjoyment of a book. I had a similar problem with Perdido Street Station.
I just enjoy being the devil's advocate.
Oh, and the little thing that folded up did not have a back. So that means it wasn't a chair? To me, anything that you can sit on that is separated into individual seats is a chair. A stool has to be either markedly higher or lower than standard seating to be considered a stool. Anything portable that creates a seat is a chair. Of course, I am sure that there are technical toes I've just stepped all over (sorry, I'm not a good dancer) but that is the way I, as a common person, interpret these things.
