Pair of Dorsal chairs by Ambasz and Piretti for Openark

Pair of back chairs by emilio ambasz and giancarlo piretti for openark, 1981. This ergonomic chair allows you to tilt backwards for more comfort. In their juice, they have wear marks on the plastic shell, the feet have several rust spots. Very beautiful pieces of design, they are in a very good state of use despite the marks of time. See photos. Plastic seats/backrests and metal structure.
