    • A coupling system (200) for coupling a chair part (106) of a chair (100) to a chair seat support structure (108) of the chair (100) is provided. The coupling system (200) comprises a receiving support (204) to be provided at one of a connecting member (120) of the chair part (106) and the chair seat support structure (108), and an insert terminal (202) to be provided at the other one of the connecting member (120) of the chair part (106) and the chair seat support structure (108). The insert terminal (202) comprises a first pin (210) and a second pin (212). In a use position of the chair (100) with the chair part (106) coupled to the chair seat support structure (108) via the coupling system (200), the first pin (210) and the second pin (212) extend horizontally from a vertical surface (214) of the insert terminal (202). The receiving support (204) provides a longitudinal support guide (206) with a stop (216) at a first end of the longitudinal support guide (206), and a pin insertion opening (218) and a recess (220) at a second end of the longitudinal support guide (206). A distance between the stop (216) and the recess (220) is essentially the same as a distance between the first pin (210) and the second pin (212) such that the second pin (212) is insertable in the recess (220) when the first pin (210) abuts the stop (216).
