Brutalist 6 chairs and dining table in teak and patinated steel, 1960s

A unique or very rare brutalist mid century dining set from the 1960s, comprising a table with a solid teak top 4 cm thick on a patinated steel base, and six chairs. The chairs are 3 varied pairs of highly individual sculptured design in solid teak and patinated steel. The chairs are (surprisingly?) very comfortable with backs that move to suit the sitter. The table measures 180 cm X 87 cm X 75 cm high. High quality, very well made, very good condition.
