1970s extendable dining table

Very beautiful dining table from the 70s, presumably from Roche Bobois, with a metal structure and a melamine top veneered with beige formica. Two extensions are integrated under the top and automatically lift when the table is opened. It then becomes oval in size 120 X 155 cm. The legs are made of aluminium and the central leg is in chrome metal. The whole is in very good used condition with just a small, very discreet white mark on one extension. Closed diameter of 120 cm and height of 76 cm.
