The French designer Michel Boyer is very more beautiful and less common and dates from the 1970s. The seat is made of hard -wearing fabric and is sewn shape. This structure and the way the seat was attached to the frame allows an extremely comfortable seating position that itself adapted. The chairs are not met, but can be assigned accordingly based on literature and documentation. The condition is very good. Both the frame and the fabric are very well preserved and do not have any stains. The bright stiffs in the photos come from the sun and do not represent spots. 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
