Perriand or Jeanneret chairs?  

I have some chairs which I inherited from an aunt of mine. I suppose she bought them between 1945 and 1955:

Seat No. 1: I have two identical chairs with the original green corduroy upholstery.
Seat No. 2: I have one chair, it has been reupholstered. The upholstery was originally the same as seat no.1.

I did some research (including Musee Arts Decoratifs in Paris) and I think it possible that these chairs were designed by Charlotte Perriand or Pierre Jeanneret.

Can anyone confirm this or point me to the right direction?
