In a physical state sharable seat, a sensor is configured to acquire a measurement value specific to a physical state of an occupant seated on the seat body; and a controller connected to the sensor and thereby allowed to acquire the measurement value from the sensor is configured to be capable of communicating with other equipment. The controller includes: an evaluation unit configured to compute an evaluation value on the physical state, based on the measurement value; an evaluation value presentation unit configured to present the evaluation value at a terminal to be used by the occupant; a shared data acquisition unit configured to acquire an other-occupant evaluation value that is an evaluation value on a physical state of another person, acquired either by the evaluation unit or from another physical state sharable seat; and a shared data presentation unit configured to present the other-occupant evaluation value at the terminal.
