The Sacco chair was a revolutionary seating concept that spawned many imitations. Colloquially referred to as a "bean-bag," its cover was constructed of either vinyl (as in this example) or leather, and it was filled with approximately twelve million semi-expanded polystryene beads, each 3mm in diameter. Because the "chair" adapted its shape to suit any sitter, it was therefore very much in tune with the informal lifestyle of the 1960s.
