No problem ;)
Last thing I just re read Memories of Charlotte Perriand ;)
P 32 "1928 Pierre Jeanneret and me,..., making armchairs and tubless Lounge...drawing 1/1 ...metal base of the lounge was found inside aviation's pieces catalog...at the evening Le Corbusier said "Stop your sterile joking"!!! p 33 :)
So it's appear that was Pierre J. and Chrlotte P. who make the lounge along days and Le Corbusier at evening validation of the work ;)
He has prefered the architecture than the furnitures (Charlotte & Pierre were there for that) ;)
