No weight limit mentioned on the chairs.
There is no chance that “Big Boned” Aunt will break it or fall through??
I found a warranty pdf on the Amazon listing (https://www.amazon.com/Flash-Furniture-Nantucket-Umbrella-Folding/dp/B07CD5W2QC).
I think it’s 250lbs, but it doesn’t explicitly state that.
(Please Note: I’m not employed by Woot, but I volunteer to help in the forums.)
It’s not stated as @pepper114 noted. Customers in the Q&A suggest 200.
