The Spectrum SB06 bar stool is a derivative of the dining room chairs designed by Martin Visser in 1960. This bar stool has a Kvadrat fabric seat and backrest (in color 946). The stool is a showroom model, never used, with unfortunately 1 very small damage in the fabric at the back left corner of the seat, which can be repaired with wool. The frame is matt stainless steel, seat height 67cm, making it suitable for a kitchen unit. Bought at De Zaak in Tilburg in the hope that I would be able to find 3 more, but I was unable to do so because Spectrum stopped production, so I bought other bar stools (from Vitra).
The frame of this Spectrum SB06 bar stool is matte chrome-plated. The seat height is 67cm, making these bar stools (usually) suitable for use on a kitchen unit.See the description of the damage above and the photos.
