Sculptural french lounge chairs 1950's.

What fantastic chairs. These chairs are from the 1950s from France. The chairs remind us very much of Michel Ducaroy's lounge chairs from SNA Roset. 
 
Unfortunately, we are not sure about this yet. We are still searching in old archives to see if we can find the exact versions. Nevertheless, these are beautiful lounge chairs with a very nice shape and of very high quality. The chairs are also in excellent condition.
