Pair of Vintage Armchairs – Gijs van der Sluis – Dutch Design – 1960s Superb pair of minimalist armchairs by Gijs van der Sluis for Sluis Steel. Black lacquered tubular steel frame and wooden armrests. The cushions have been reupholstered in a high-quality mottled fabric (made from plastic bottles). Comfortable, understated, and very elegant. Excellent condition. 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
