The Opus armchair, designed by Søren Nissen and Ebbe Gehl, was manufactured in 1982 in Denmark by Nielaus and is a confirmation of the elegance and comfort of modern Danish design. These chairs feature front legs that extend into the arms. The upholstery is original with blue fabric. A pair of elegant chairs to add light to your home. 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
