Several years ago, I bought an office chair from an acquaintance. It was used when I bought it; I have no idea how old it is. I’ve lost touch with this acquaintance, so I can’t ask him where or when he bought it.
My problem is two-fold: (1) it’s wearing out, and (2) it’s the most comfortable chair I’ve ever used for “office-type” work (using the computer for long periods of time, etc.). I’ve looked it over, including looking underneath, and there are no identifiers whatsoever–no brand name, no store name, etc. I’m hoping that somebody here will be able to give me some idea of what brand it might be, or at least what terms to search for in order to find one similar.
