We held a Friday the 13th party, and a very heavy person Im guessing weighing about five hundred pounds sat on one of these chairs for the duration of the night without an issue. My daughter informed me the next day when I saw our broken couch that it had been her, so these chairs can really hold up! My husband is a big man and I was worried about him using the set, but not anymore! It passed the ultimate stress test! I think I could maybe even sit in his lap safely. :)
