502 Foster armchair Walter Knoll

Clarity, comfort, character: 502 Foster armchair from Walter Knoll

A piece of furniture that speaks architecture: the 502 Foster armchair from Walter Knoll is the result of a collaboration with the renowned architect Lord Norman Foster. The result is an armchair that impressively embodies the values of modern design - precise lines, functional elegance and a superior seating experience. The design language of the 502 Foster is minimalist, but never cool.

Clear contours and generous upholstered surfaces convey a feeling of security and calm. The armchair appears light and powerful at the same time - a haven of peace in the room that impresses with its presence without appearing dominant. Manufactured with precision craftsmanship, the 502 Foster offers maximum seating comfort. High-quality materials such as fine leather or exclusive fabrics meet carefully crafted upholstery that invites you to lean back and relax. The filigree base lends the design a floating lightness and emphasises the architectural aesthetics.

Walter Knoll - furniture with a history

The company's history has its origins in a "leather shop" in Stuttgart, which was opened in 1865 by the forefather of the Knoll dynasty, Wilhelm Knoll. In the same year, the seating furniture manufacturer demonstrated his craftsmanship as purveyor to the court of the King of Württemberg. 42 years pass before son Walter takes over the company together with his brother Willy. In the meantime, branches were opened in the metropolises of St. Petersburg and Vienna. In 1925, Walter Knoll founded his own upholstered furniture factory, which has borne his name ever since, in order to set himself apart from the design of his father's company. In addition to leather, coloured fabrics were now also used as upholstery materials. In the 1920s, the invention of the anti-mott spring and the Prodomo system revolutionised the traditional upholstered furniture trade. The furniture of the Prodomo system in particular, with its curved tubular steel frames, pointed the way to modernity. Walter Knoll has been expanding steadily since 2001, and the company has opened showrooms in Berlin, Hamburg, London, Paris, Stockholm, Beijing, Mumbai and Adelaide (Australia) in the last 10 years.
