The Bofinger chair, also called BA 1171, was designed in 1964 by architect and designer Helmut Bätzner. The Bofinger stacking chair was developed into the world's first one-piece plastic chair made of glass fiber reinforced polyester that was mass-produced in a single pressing process over a steel mould. The Bofinger chair is considered one of the most important classics in modern furniture design history.The chairs are really in excellent condition. Some usual scratches here and there.
