I'm quite sure that the seats are not rated for anywhere near that. Even
if
they are, as the maintenance officer who has had these 28 year old seats
out
many times to repair the trim and covering, there is no way I want to put
350 pounds on them.

Why are you sure?

I knew a guy that large who was a pilot. My mechanic is that large, and
he's ridden in my plane with no problem. The seats in my plane are even
cheaper-built than a 172's.

350lbs is pretty big, but it's not clear to me why you think it's
disqualifying.
