What Thonet highlights

  • No back legs

    Mart Stam removed the back legs, so the chair rests on a cantilevered tubular steel frame. Thonet owns the artistic copyright for this cubic design.

  • Steel and moulded wood

    The frame carries a moulded wood seat and backrest. Upholstered versions are also offered.

  • Wide family

    Versions add armrests or stacking, and the range includes a swivel chair, a bar stool and a children's chair.

As described by Thonet on its official pages; not a Chairpedia assessment.
