Thanks for your help, but I have already looked about Norreklit and Osterig and found nothing. But perhaps you are right and I don't have the good documentation. Or maybe it's another designer..;

Many thanks Simon. I was sure this sofa couldn't come from "nowhere", and Poul Norreklit is the kind of answer I like. I didn't know this story about Selectform. We learn everyday in this job ! I hope I can do the same for you one day (but not on danish furniture!). Have a good day. Luc
