First chair broke within a month, thought there may have just been an unfortunate flaw in that wood. but..we are down two more since then (bought them in May 2021).
I dont have kids or anyone who would use a chair improperly, and all of use are adults under the advertised weight limit just Sitting in the chairs normally. Seems like eventually you will lean back and it will break at the point where the back rest joins the seat.
