Lounge Chair Base Identification Comparison Vitra | Herman Miller

Lounge Chair Manufacturer Identification
In 1957 VITRA started production of the Lounge Chair with license of Herman Miller. The Lounge Chair over all was the same, but the base is different to that used in US.
The picture shows the difference to identify, if your Lounge Chair is a Herman Miller US production, or a Vitra European production. You just need to compare the base.
Please note: Early Vitra production Lounge Chair may also have a Herman Miller label, but if it has the Vitra or European base it is Vitra or European production!
In 1970 licenses to manufacture where given to NK in Sweden, ICF in Italy, Hille International in the UK and Mobilier International in France. All have the European Vitra base.
