An object of the present invention is to provide a dual extension device capable of stably supporting left and right thighs of a passenger by dividing an existing integrally operated extension device into left and right panels and independently controlling the left and right panels. A dual seat cushion extension device comprises: a pair of left and right slide rails which are provided on the lower part of a main panel forming a frame of a seat cushion so as to be drawn out to the front; a pair of left and right extension panels which are respectively hinge-coupled in the leading ends of a pair of slide rails; and a pair of left and right lead screws which are connected to a pair of extension motors in the lower part of the main panel so as to be individually driven and are respectively hinge-coupled with a pair of extension panels on their ends. When the lead screws are driven forward by the individual driving of the extension motors, the extension panels hinge-coupled to the ends of the lead screws slide along the slide rails and rotate forward and upward, simultaneously extending forward.
