503 Foster armchair Walter Knoll

The art of the essential: 503 Foster armchair from Walter Knoll

With the 503 Foster, Walter Knoll consistently continues the design philosophy of Lord Norman Foster: clear lines, reduced form, maximum effect. The armchair is an expression of pure elegance - architecturally conceived, perfectly crafted. Its appearance is restrained and striking at the same time. The slim silhouette, balanced proportions and well thought-out ergonomics make the 503 Foster the perfect companion in prestigious lounges, conference areas or modern living environments. Here, sitting becomes a posture - upright, relaxed, stylish. Made from fine materials such as hand-picked leather or the finest fabrics, the 503 Foster impresses with its tactile quality and long-lasting substance. The fine metal frame supports the upholstered shell with lightness - a tension between stability and visual calm.

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.
