Extendable table and 60's chairs

Table and chairs teak 60s. I do not know the name of the designer but the lines are simple but worked. The chairs are covered with an original black sky and their solid wood structure. The table top is in teak veneer and the legs in solid wood. This table contains two discreet and integrated extensions (sliding) allowing to provide 4 additional cutlery. Good condition (traces of use, micro scratches). Scandinavian spirit or French design
