Visionary designer Flemming Lassen’s 1935 sofa Vilhelm, named for his father alongside Ingeborg chair in honor of his mother, is defined by its graceful curves and taut upholstery tufted with 24 individual buttons. On low solid-oak legs, its sheltering contours invite genial conversation or solo repose and its rounded corners also allow it be a statement piece when placed in the middle of a room.
