A living support system connected to a chair including a movable seat through a communication network includes a robot including a main body, a moving device that moves the main body in a freestanding state, a handle provided at the main body and gripped by a user, and a handle load detector that detects a handle load applied to the handle by the user; a support control device that controls seat movement for a stand-up motion of the sitting user, using the detected handle load; and a communicator that transmits support control information including a movement speed at which the chair moves the movable seat, to the chair through the communication network. The support control device includes a seat speed calculator that calculates a speed at which the movable seat is inclined with respect to a floor on which the chair is placed, as the movement speed using the detected handle load.
