Vintage tripod armchair, designer seating furniture

1960s/70s. Dimensions 102x70xh86cm, seat 40cm. Solid wood. Leather suspended seat. Very comfortable. It is old, has been used and therefore has some discreet signs of use, see photos: some scratches on the wood and leather, some coloring and discoloration of the wood. Clean and minimalist Brazilian modernist design, perfect for a Scandinavian or brutalist interior. Referenced on some sites as furniture by Lina Bo Bardi.
