This set of armchirs was designed in the 1960s by Alfa Svensson and manufactured by Dux. The frame of the chairs is made of solid beech wood, which has undergone carpentry renovation consisting in removing old coatings, staining and finishing with varnish. The seat and backrest of the chairs have been upholstered in a new black natural leather. The upholstery sponge was also replaced. 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
