Set of eight Omstak chairs designed by Rodney Kinsman in 1972 and produced by the Italian manufacturer Bieffeplast. The Omstak chair is recognized as one of the icons of early High-Tech design. Conceived as a lightweight, stackable seating system, it represents a milestone of 1970s industrial furniture. Since its introduction, the Omstak has remained in continuous production, with sales exceeding one million units worldwide. The design is characterized by a perforated white lacquered metal seat and backrest combined with a chromed tubular steel structure. This construction expresses the industrial and functional approach typical of the period, emphasizing lightness, serial production, and technical clarity. The importance of the Omstak chair is confirmed by its inclusion in major international museum collections, including the Victoria and Albert Museum in London, the Design Museum London, and the Philadelphia Museum of Art. This set is in very good vintage condition and has not been restored. Each chair has been individually inspected by our workshop in Italy to ensure proper stability and functionality. Upon request, restoration, refinishing, or customization services can be discussed to adapt the chairs to specific interior or project needs. 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
