Piero Gatti, Cesare Paolini and Franco Teodoro, inspired by their designer predecessors, came up in 1968 with the design of Sacco the ‘shapeless chair’. Although it was not the first design of an amorphous chair in Italian history, Sacco was the first successful product created in partnership with Zanotta. The predecessor of the product had a major design flaw of not being able to sustain its form and therefore never reached production. Sacco picked up that flaw and with the use of leather for exterior and right placed stitching. It is worth mentioning that the use of leather was not coincidental as at that time the textile was an Italian national pride product. The target user of the chair was the lax, hippie community and their non-conformist household. "In an era characterized by the hippie culture, apartment sharing and student demonstrations, the thirty-something designers created a nonpoltrona (non-chair) and thus launched an attack on good bourgeois taste."
