Dutch industrial designer Wim Rietveld (1924–1985) was known for his functional, user-friendly designs. He studied Industrial Design at The Hague Academy before becoming head of design at Gispen in 1953. While working at De Cirkel in 1958, he collaborated with Friso Kramer to create the Result Chair, a classic of Dutch modernism. He also designed the Pyramid Tables and Chairs in 1960. HAY, in partnership with Ahrend, has reintroduced the Result Chair and Pyramid Collection.
