4 vintage brutalist chairs, reupholstered in cotton/linen

4 vintage brutalist wooden chairs with seats reupholstered in a cotton/linen fabric made in france. In excellent condition despite their age (circa 1970s). Under the fabric is foam for a comfortable seat. Some normal signs of wear and tear (see photos): 3 marks of varnish discoloration, superficial scratches. But overall the wooden structure is in very good condition.
