Bellini for Cassina cab chairs in natural Italian leather. High-quality chairs consisting of a leather cover stretched over a minimal tubular steel frame. The only additional reinforcement is provided by a rubber membrane plate that supports the seat. Bellini’s innovation lay in using zips to fasten the leather cover to its frame; a zip runs up the inside of each leg, sealing the cover in place. Bellini’s decision to completely envelop the supporting structure lends the chair a unified appearance and enhances the quality of the natural leather. Beautiful 1970s vintage condition. Marked.
