The chair has a back rest which can be moved to various positions between an initial position and a position where it is horizontal. The seat is attached to a mounting plate (5) which carries a catch (12) with a serrated upper edge (18). This cooperates with a latch (17) attached to a mounting plate (6) on the back rest to fix it at different angles.
