A futon frame includes a pair of linear actuators mounted at opposing sides thereof for driving a folding seat and back of the frame to automatically and continuously adjust the seat and back between a sofa position and a bed position. The back is connected to opposing sides of the frame by upper and lower follower bearings arranged for travel within corresponding upper and lower guide channels in each opposing side of the frame. A motor controller is mounted to the underside of the seat for connecting a user interface to the linear actuator motors.
