Stackable chair Italy 1980 (10 pcs available)

Vintage adult chair, which fitted the refectory of the town of Cesate in Italy. 10 pieces available. As colorful as they are solid. Both the dining room and outside in the garden. Steel base, plastic seat. Very sturdy. The Swedish Helmut Starcke and Grosfillex produced similar ones. I haven't been able to identify the manufacturer, in the last photo, but if anyone has any information...
