Set of 2 easy chairs designed by Gijs van der Sluis by van Der Sluis Steel Furniture, Netherlands 1960s. This Mid-mid-century set has been reupholstered a couple of years ago with new foam and blueish teal fabric from De Ploeg and is in good condition.The frames have a graphite gray color in excellent condition. The chairs themselves are not very big, but they do have a large seat and backrest. This allows them to maintain great comfort and makes them suitable for smaller spaces. Very stable and sturdy objects. 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
