This is for cdsilva who suggested the topic in thread #44 about our latest finds.
The Hundevad folding stool is the one most people know about. My personal history with it is just that I was asked to make a new leather seat for one. I knew it was based on one that was found in a bog gravesite but had always assumed it was a stylized version. So when I looked it up I was very surprised that it was a near-exact copy.
The National Museum of Denmark has a page about it with more facts and photos of the original.
There's also a photo of a 1934 Egyptian style folding stool designed by Ole Wanscher. I didn't know until just now that he had designed one, too.
