Balloon chair  

I certainly know of no documentation that would suggest that. I think it would be more likely that someone invented the Hans Olsen thing for financial reasons and people have continued to repeat it.

i would stick with that as the more likely explanation unless you can turn up another vintage ad that contradicts the one you posted.

Hi.

Very odd that they used Patty Hearst as their advertising "model".

Best,

Can't see any of the pictures in this thread but did anyone ever find any documentation saying the Balloon Chair was designed by Olsen?

@ponyboy. I think the image posted by Dr. Poulet may have been this one 🤔 ; no way of knowing but it is the only advert I found. Image courtesy of https://www.danish-modern.co.uk/lea-ballonstol/
