PHYSICAL STATE SHARING SEAT

A seat having features of evaluating a physical state of a seated occupant, in which motivation to use the features is enhanced, is provided. A physical state sharable seat is proposed which includes: a seat body; a sensor (8) configured to acquire a measurement value specific to a physical state of an occupant seated on the seat body; and a controller (100) connected to the sensor and thereby allowed to acquire the measurement value from the sensor, and configured to be capable of communicating with other equipment. The controller (100) includes: an evaluation unit (121) configured to compute an evaluation value on the physical state, based on the measurement value; an evaluation value presentation unit (122) configured to present the evaluation value at a terminal to be used by the occupant; a shared data acquisition unit (161) 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 (162) configured to present the other-occupant evaluation value at the terminal to be used by the occupant.
