This swivel office chair, designed by Gordon Russell, was manufactured in the UK in the 1970s. The teak wood components have been cleared of their original surface, painted with oak stain, and finished with a strong, semi-matte varnish. The interior upholstery has been replaced with a high-quality black fabric. Seat height ranges from 49 cm to 57 cm. 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
