The invention provides a longitudinal and transverse direction convertible chair, which comprises a seat, a chair back, an armrest connected between the seat and the chair back, and a base rotatably supporting the seat, the seat and the chair back are rotatably connected through a shaft hinge, the armrest comprises an upper rod body and a lower rod body, and the upper rod body is connected with the lower rod body. One end of the upper rod body is rotationally connected with the chair back through a shaft hinge, the other end of the upper rod body is rotationally connected with the upper end part of the lower rod body through a shaft hinge, and the lower rod body is rotationally connected with the seat through a shaft hinge, so that the chair seat, the chair back and the armrests are connected to form a parallel four-rod mechanism; and the lower rod body is rotationally supported on the base. The side of the seat, the side of the backrest and the armrests are connected to form a parallel four-bar mechanism, the seat can be deformed by lifting the armrests, and the backrest is far away from the side wall of a carriage, so that the longitudinal and transverse adjustment of the seat can be realized under the condition that the distance between the seat and the side wall of a vehicle is not increased.
