Danish-American Jens Risom partnered with German-American Hans Knoll to create the Knoll Furniture Company – one of the first furniture companies to produce Scandinavian designs in the United States. The initial line released in the 1950s included the Vostra Chair. Its ergonomic shape and simple design made it a popular choice for casual seating. Initially designed with canvas webbing, another iteration designed with foam cushions allowed the Knoll company to offer the chair with a variety of upholstery patterns. O’Keeffe purchased one with a busy brown and white pattern but when she tired of the upholstery, she used a white linen cover.
