Abstract: A folding chair, having a seat and a backrest hinged together and supported by two pairs of crossed legs pivotably associated one with another, is adjusted by way of a device making use of a pivot, associated with the top end of one leg and rotatable about its own axis, which features an oval head with a double cam profile and a pin extending issuing from the head; the pin and the head occupy first and second tracks of substantially zig-zag profile, integral with or fitted to the chair seat, and adjustment of the reclining angle of the chair is effected by moving the pivot along the tracks from end to end through a sequence of mandatory steps that coincide with a plurality of stable positions of the pivot, each corresponding to a given angle of the backrest.
