Danish designer Verner Panton spent many years thinking about how to produce a plastic chair moulded in one piece. Together with Vitra, he came up with the first prototypes in the 1960s and Panton Chair went into series production as of 1967. Unlike the cheaper Panton Chair Standard in solid plastic, Panton Chair Classic is made of rigid expanded plastic and has a lacquered surface. Because of technical progress in plastics processing, the Panton Chair has been through a number of production phases since its original launch. The last version of the chair authorised by Verner Panton was produced in collaboration with the designer at the end of the 1990s. This model realised one of Panton's fundamental objectives for the first time: a plastic chair as an inexpensive industrial product.
