Arne Jacobsen (1902-1971), a Danish architect and designer, who developed this legendary "no straight lines - only curves" Swan Chair in 1958. Formerly used for the lobby and lounge areas at the SAS Royal Hotel in Copenhagen. The chair allowed guests to spin on its swivel base, thus becoming active participants in the busy hotel atmosphere. His first design used Styropor (an expandable polystyrene, invented by BASF in 1951, commonly used today for cost-effective, yet reliable construction for packaging. e.g. salmon packaging) to create its continuous shape and the upholsterer hand-sewn the fabric directly to Swan's frame.
Along with the Swan, he created the Egg chair, which had been acclaimed as one of the triumphs of his total design. Jacobsen introduced a new technique, using a strong foam inner shell underneath the upholstery, that guarantees a bit of privacy in public spaces. Just like an egg shell.
