Pair MARCEL BREUER Wassily Black Leather Lounge Chairs. The Marcel Breuer Wassily Black Leather Lounge Chair, also known as the B3 chair, is a classic piece of modernist furniture known for its innovative use of tubular steel and leather. Designed in 1925, made by Knoll in the 60s, it was one of the first chairs to utilize a tubular steel frame, inspired by bicycle construction, and features leather slings for the seat, back, and arms. The chair's sleek, minimalist design and use of contrasting materials (steel and leather) make it a recognizable icon of the Bauhaus movement.
