Cutter is Mario Bellini’s new chair with strong and decisive aesthetics which create a new type of seating. The back of the chair is slashed by a cut which is pays homage to the great artist Lucio Fontana. Although evident, Cutter’s nature does not only lie in an aesthetic choice but generates an unprecedented type of seating. The twin backrest’s ends are functional and comfortable in a frontal position, while moving independently and allowing a lateral position. This gesture is suitable for chatting with the person seated nearby. It is also designed to ensure high comfort seating and casual movements, allowing the user to lean on one side with an arm placed around the backrest. The seating frame is made of metal and webbing, softened by a classic polyurethane upholstery. To guarantee elasticity and strength to the double backrest, B&B Italia’s Research & Development Centre has opted for a sophisticated harmonic steel core. The upholstery and cover fully envelop the chair in embossed thick leather, creating an ideal synthesis of softness and rigour, underlined by saddle stitching.  The central cut reveals an inner part in refined black Saffiano thick leather, as if Cutter’s soul peeps out from this dramatic opening.
