Well, yes, I have been that mad but I know the chair would hurt me more than I would hurt it. LOL You might have an absolutely awesome business if you were to offer a room like that! The main problem I see would be scheduling visits (no planning ahead!) and recycling broken chairs. :)
I remember hearing about a business in New York where they would rent out time in a room filled with junk furniture and a tv. They'd have to sign a waiver, give you goggles and a baseball bat, and let you go to town.
My idea is a bit more personal because I used to destroy chairs as a young man and it was very satisfying. I'm not talking recliners or anything... more like, cheap lawn chairs I guess. lol
Seriously? TOO FUNNY! Well, if you ever need another occupation you've got an idea! You could also have them sign a waiver and record the sessions. It might be therapeutic for other people to watch someone else destroying furniture. Vicarious anger venting?
