3 Spaghetti chairs by Alias

Hello, I am selling a set of 3 Alias Spaghetti 101 chairs (1979) designed by Giandomenico Belotti. These chairs are not copies! They are made of black lacquered steel, with a seat and backrest in PVC wire. There are some signs of use on the structure. See photos. Overall good condition: wires are well tensioned. I have new pads that need to be fitted. I am not handy! The chair is part of the permanent collection at MoMA in New York.
