At last I got some more info about the strange Wire Cone Chair I bought some months ago. I have now found pictures and more info with the very same chairs!
There was a very cool disco in Odense, Denmark, called “Disco Tiffany” and in 1981 they ordered 80 chairs, 19 tables, 6 Bar Stools, a lot of Mira-X fabric and also a big wall to wall carpet with Verner Pantons design from X-Design. Everything in red. You can here see the original floor plan from X-Design and pictures with the very samy chairs as the one I found. Unfortunatelly there is not a trace left of the interior. It was made in 1981 and three years later the disco was sold. Everything was then thrown out.
The orange chair I got is from another location but I would love to hear the story about it. If anyone have seen this chair somewhere, please let me know.
