The modelling method of rapid prototyping served as the starting point for this design. At the time, I was reading a book about Paul Klee in which he said that when he was drawing, it was like taking the line for a walk. This expression gave me the final theme to design a lightweight structure for a lounge chair with enormous wings. The upholstered version of this came a year later. To be able to sit in it without being concerned about one's shoes was a small detail in this autonomous structure. alfredo haeberli website
