This heavy duty version of a swivel steel tube desk chair with tilt was manufactured in Germany during the 1930s by Mauser Werke. The seat is upholstered with dark forest green skai. The chair features great details. It is an iconic piece with character, an impressive German original from the 1930s. It shows some wear and tear but is absolutely suitable for everyday use. 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
