​Chaos model armchair produced by Biesse, design Pepe Tanzi, year 1987. Chromed steel structure, shell in green mottled transparent resin produced by manual casting. The armrests inside have a steel core and are covered in resin of the same color as the armchair. 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
