A power adjustable arm rest assembly is disclosed wherein the angular altitude or pitch, as well as the vertical height, of a movable arm rest portion are adjustable independently of one another in order to maximize user comfort. The mechanisms for independently adjusting the angular and vertical positions include powered actuating devices near either end of the movable arm rest portion that are connected to a fixed mounting member in order to accommodate angular adjustment. The actuating devices further include extendible and retractable armature members pivotally interconnected to the movable arm rest portion and are energizable and deenergizable in order to respectively urge the movable arm rest portion to, or hold the movable arm rest portion in, preselected adjusted positions.
