Addison, in its lounge chair and 2- and 3-seat sofa versions, channels the vital spirit and comfortable surroundings of Berkeley’s arts district. Four-inch-thick upholstery and undulating contours present an appearance as welcoming as an Addison Street jazz club. A narrow band of wood and angled feet offer a dramatic contrast to Addison’s upholstery, in a choice of fabric or leather, while providing strength that belie a delicate form.
