I have a male friend who is the same size as yours. He is aware that he is fat, and we have had some honest discussions about the issue that none of my furniture is wide enough or may not be strong enough to hold him. In order to spare him embarrassment we have decided that we would visit at his home where he knows that no matter where he sits, he will not break anything and he knows that he can fit through the bathroom door and he knows that he can get up from a sitting position without struggle.
