Actually, one had a broken leg and they were afraid for anyone to sit in it. I jumped on these - what did I have to lose. I first removed all the fabric. A little wood glue and a couple of screws fixed the leg, and a couple of cans of off white spray paint gave me an instant improvement.
I fell in love with the fabric as soon as I saw it. A couple of yards later, those ugly 70's chairs are now updated and cool. The are also back where they belong - my office!
