This set of six dining chairs was produced by Zamojska Furniture Factory in Poland circa 1970. It was designed by Juliusz Kędziorek. Completely restored. The sponges have been replaced. The seats have been reupholstered with new green fabric. The frames are made of beech. Wood has been cleaned of the old surface, painted with an dark walnut stain and finished with a strong semi matte lacquer. 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
