Folding stool with two triangular supporting structures and a triangular seat which forms a load-bearing structure by virtue of the arrangement of the angular position, of the joints and the securing bolt, which connects the outer supporting structure and the seat. In the folded-up position, the securing bolt connects all 3 vertical parts (2 supporting structures + 1 seat) and thus prevents the unintentional opening-out of the stool.
