Chromed steel structure and leather seat and back
Stam Breuer Mart Style Chairs

They are intact and stable but I would like to point out that they have some signs of aging.
in some places there is a speckled patina of oxidation on the steel
In one chair the leather has slightly worn edges
In one chair all the black rubbers are missing and in the other series some are not fixed
