Irreverent, Sacco is one of the most representative objects of Italian design of the late 1960s. The three designers want to create a universal seat that adapts to every user and every situation. Sacco desacralises and redefines the action of sitting which becomes a ritual and a personal or collective expression. The legs, seat and backrest disappear, releasing the potential and functionality of this object. Composed of a PVC cover folded with polystyrene beads, Sacco takes the shape of the body that sits or lies on it. Under the weight of the person, the balls migrate into the upper part which becomes a support for the head.
