Series of elements designed to fit out the Arne sofas to extend their furnishing qualities: a vertical bookcase, a low swivel bookcase, a horizontal storage unit that can stand alone or be combined with a counter, and which can also be used as a back-sofa because it can follow the sofa’s curves, and a low table. They are all characterised by the use of curved wood and by interplaying full and empty spaces that, associated with steel-rod supports, convey visual lightness.
