An electric seat in which other members are prevented from being damaged and thus safety is ensured.When a current consumed by the leg rest motor during the downward pivotal movement of the leg rest is larger than the reference value for the downward movement of the leg rest, the switch for the motor is opened. In a case where the leg rest is pivoted downward with a baggage placed in the operating space of the leg rest in the bed position, when the leg rest abuts against the baggage, a large load is applied to the leg rest and a current that exceeds the reference value for the downward movement of the leg rest flows in the leg rest motor, the switch is opened, the respective motors are actuated, and the downward pivotal movement of the leg rest is stopped. Therefore, the leg rest is prevented from pressing the baggage unnecessarily, thereby preventing the baggage from being damaged.
