The interplay of functionality, aesthetics and material is characteristic of all chair designs by Vitra – contemporary creations such as HAL by Jasper Morrison and Alfredo Häberli’s Jill. These and the many other Vitra chairs stand for excellent design and high-quality workmanship. They are milestones of furniture design, in some cases having been produced by Vitra for more than fifty years. These include such chairs as the Panton Chair by Verner Panton from 1959/60. Other models date back even earlier, like the Standard Chair by Jean Prouvé from 1934. More recent contributions to Vitra’s collection of chairs show that current day designers continue to cultivate a love of experimentation. For instance, Tip Ton by Edward Barber and Jay Osgerby from 2011 defines a new chair typology. From a normal position, the solid plastic chair can be tilted forward a few degrees to promote healthy sitting.
