Like Design by Luca Nichetto
The inspiration for the sofa "Linea", which was designed by Luca Nichetto for Offecct, came from the animated cartoon "La Linea", created by Osvaldo Cavandoli. His character walks around on an infinite line, of which it is part.
Small shelves can be joined, which makes it possible to bend the benches' path.
