Been there and done that. And was embarrassed as all get out. Good news is you are on the way down to better health. And for the sake of argument when I was in the service and weighed all of 165 pounds at 6'4" tall post Vietnam, I sat on a folding metal chair and it broke. Nobody thought a thing of it. Faulty chari. Let it happen to me now and I guarantee that nobody would even consider the fact that it might have been a bad chair!
