An electric reclining chair has a base, a linkage mechanism, a leg rest mount, and a control module. The linkage mechanism is movably mounted to the base and connected to a driver. The leg rest mount is pivotally connected to the linkage mechanism. The control module has a sensor module and a control unit. When the linkage mechanism and the leg rest mount are being folded by the driver, if an object is under the leg rest mount and abuts the leg rest mount, the leg rest mount pivots relative to the linkage mechanism, which is sensed by the sensor module. Thus, the control module controls the driver to stop folding the linkage mechanism or to unfold the linkage mechanism so as to prevent the object from being pinched.
