I went to see a dealer I know on Saturday and he had a pair of these chairs. I have asked for the maker and he told me they were usually attributed to LEA design but doubted it was true.
After some research, it seems that they were indeed made by LEA but in house design which is pretty funny as they are usually attributed to Hans Olsen / maker unknown.
I was wondering if you guys can confirm or not that the balloon chair has indeed been designed by Hans Olsen? We all know that in house design can mean a lot of things....
