2 beds, 1 couch, 1 recliner, 1 combined desk/chair in high school, 2 glider rocking chairs, 1 office chair, more than a few plastic lawn chairs... Oops!
I have broken numerous dining room chairs, some at friend's homes, which is embaressing but inside secretly exciting to me. Have also broken outdoor folding chairs and numerous toilet seats. Finally found some plastic ones that hold up quite nicely.
Over my lifetime: 3 beds (2 that weren't mine), 4 toilet seats, 5 couches that were sunken in in my spot, 1 rocking chair, bent 2 metal chairs and I dunno how many office chairs but it's usually busting one of the arms out or scooting and breaking off the wheels on the legs...so I'd say maybe 8 to 10.
