An automobile seat is composed of a seat cushion, seat back, and supporting element. The seat cushion supports the hip portion of a vehicle occupant at its normal position. The seat cushion is disposed so that the seat cushion may be freely movable while being forwardly rotated about a front end supporting fulcrum from the normal position to an inverted position. The seat cushion has a reverse surface which is made substantially horizontal at its inverted position. The seat back supports the back of the vehicle occupant at its normal position. The seat back is disposed so that the seat back may be freely movable while being forwardly fallen down from the normal position to a fall-down position. The seat back has a rear surface which is made substantially horizontal at its fall-down position. The reverse surface of the seat cushion at the inverted position and the rear surface of the seat back at the fall-down position are located at substantially the same height level. By the movements of the seat cushion and seat back to their respective inverted position and fall-down position, the seat has its attitude changed from its ordinary state to its flat state. The supporting element fixes the seat cushion and seat back to an automobile body. The supporting element supports the seat cushion and seat back so that the seat cushion and seat back may be freely backwardly slidable from a first position for the ordinary state to a second position for the flat state.
