Claim 0:
1. A seat comprising:
a seat body;
sensors configured to acquire measurement values for use in identifying motion of an occupant seated on the seat body, the measurement values including values of pressure from the occupant seated on the seat body; and
a controller connected to the sensors and thereby allowed to acquire the measurement values from the sensors,
wherein the seat body comprises a seat cushion and a seat back,
wherein the sensors comprise:
a first cushion sensor provided at the seat cushion in a position thereof corresponding to buttocks of the occupant,
a second cushion sensor provided at the seat cushion and located farther frontward than the first cushion sensor,
a first back sensor provided at the seat back and located in a lower position thereof, and
a second back sensor provided at the seat back and located above the first back sensor,

wherein the controller is configured to:
identify the motion of the occupant based on a combination of changes of outputs of at least two sensors selected from a group consisting of the first cushion sensor, the second cushion sensor, the first back sensor, or the second back sensor, the controller comprising:
a motion instruction unit configured to give the occupant an instruction to perform a predetermined motion; and
a motion determination unit configured to:
identify the motion of the occupant based on changes of outputs of the at least two sensors compared to measurement values of the at least two sensors acquired when the occupant is in a reference posture,

determine, after the motion instruction unit gives the instruction, whether or not the occupant is performing the predetermined motion,
wherein the changes of outputs of the at least two sensors are determined by comparing the outputs of the at least two sensors with stored threshold values, and
wherein the threshold values are set for each occupant, and

wherein the motion that the controller is configured to identify includes a motion of the occupant lifting a heel or foot up from a floor.
