For daily family use, we recommend a load rating of at least 330 lbs, stated by the maker; for contract use, also look for a named strength test such as EN 16139. Every by Crea bar stool carries our own 440 lbs rating, steel and oak alike.
The table shows what to look for. A stool with no stated rating is not necessarily weak, but it leaves you guessing, and on a seat 26 or 30 in off the floor, guessing is not what you want.
