The Panton chair is an important icon of modern design and has a fascinating history as Verner Panton experimented with a variety of materials to best realize the design. The most commonly seen versions are the chairs made of Luran-S, colored thermoplastic polystyrene and the contemporary version in flexible polypropylene. However the chair was originally made by Vitra with Baydur HR cold-molded, fiberglass reinforced polyester resin foam which would then be primed and painted. The resulting chair was very time and labor intensive, yet yielded a chair which was much more substantial, with greater heft and a more elegant sculptural quality not needing any visible reinforcement. These chairs do not have a “plastic” feel. In 1979 production of the Panton chair ceased. However, in 1983, Horn GmbH & Co. KG in Rudersberg began making the chair using HR foam again, and sold it through the WK association. These 6 chairs are marked with Panton’s signature at the bottom of the back and were made with the same method as the original production.
