Cidue Italian chairs

Italian design chair from the 1980s. Made in italy by cidue (c2). Original label under the chair (see photos). The seat is made of aluminum, the base and the back are made of a steel tube painted black. These are chairs that I bought personally in 1985 and which accompanied a round glass dining table on a black metal base from the roset line which I unfortunately broke recently! (i kept the table leg if anyone is interested). These chairs have therefore only had one owner. I would like to point out that the aluminum on one of the seats is slightly scratched but the defect should disappear after polishing I think. The rest is in very good condition. Sold in batches, I have four.
