THREE IKEA STIG bar stools with backrest, black

IKEA STIG bar stool with backrest. Black colour with a sturdy frame. Counter height. You need to pick all three of them and I think two of them are fragile to use with heavy weights. They feel a little shaky. I don’t know if it would be fixable because I haven’t tried it. I wanted to post some videos regarding this latter but it seems to be impossible. If you don’t mind plz feel free to reach out to me!
