Overview: The story of design enters the 50s and 60s, when a revolutionary new material called plastic combined with the miracles of electronic miniaturisation to allow designers to offer post-war consumers something new: liberation. Designer Verner Panton pursued the seemingly impossible dream of a chair made from a seamless piece of plastic while Joe Colombo proposed the Austin Powers-style 'cabriolet bed', complete with built-in cigarette lighter and stereo. Meanwhile in Japan, designers at Sony were shrinking radios from pocket-size to palm-size, paving the way for the ultimate in portable lifestyle-the Walkman. But the optimism of the era came to an abrupt end when concerns about the environmental impact of plastic came to the fore.
