The series is called ‘ateljee’. A series in which most sofas are made as one piece. But this sofa consists of three separate parts, making it possible to transform the three-seater sofa into a two-seater sofa plus an easy chair. 3-seater = h x w x d = 70-35 x 220 x 80 cm / 27.6-13.8 x 86.6 x 31.5 inch. 2-seater = h x w x d = 70-35 x 155 x 80 cm / 27.6-13.8 x 61,1 x 31.5 inch. 1-seater = h x w x d = 70-35 x 65 x 80 cm / 27.6-13.8 x 25.6 x 31.5 inch. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution
