This versatile lounge chair is made of a steel frame, padding and foam. It feautures two side knobs in order to adjust the back; the headrest is divided in two parts, each with an independent reclining position. It is possible to change the armchair in a chaise longue just by tilting the base forward. 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
