At last! This rare ”Sitzshaukel” from the legendary exhibition ”Visiona 2” didn’t come with a cushion when I got it. It was meant to have a cushion with removable cover – or to use it without.
With the help of several professionals and photos from the time, it’s now not only super cool and good looking – it’s incredibly comfortable! 
Thanks to all the people at www.ptv.se for making the advanced cushion inside and thanks to @goteborgssyfabrik for making the cover.
It doesn’t look that difficult when you see it here but I promise you they struggled hard (and I guess they don’t want to see me again for some time…)
