A powered lift chair comprises a frame, a backrest, left and right armrests, a seat, a footrest, and a pair of linear actuator mechanisms. A first one of the pair of linear actuator mechanisms is utilized to control the backrest of the chair, while the second one of the pair of linear actuator mechanisms is utilized to move the frame of the chair between a lowered position and an elevated position, as well as to move the seat of the chair between a substantially horizontal orientation and a tilted orientation such that the forward end portion of the seat is tilted downwardly while the rearward end portion of the seat is tilted upwardly, all while the left and right armrests are fixed in position and disposed within horizontal planes. Such compound movements of the chair and the seat will stably assist a person to be moved from a seated position to a standing position while the person is able to grasp and push downwardly upon the left and right armrests whereby the fixed armrests will effectively provide the person with stable platforms upon which the person can reliably, securely, and safely place his or her hands so as to assist himself or herself to move from the seated position to the standing position.
