An automotive arm rest is set forth for securement to a window sill of an automotive door. The automotive arm rest comprises a plurality of elongate expandable chambers positioned adjacent an upper edge of the arm rest. A plurality of generally flexible "L" shaped clips project upwardly of the arm rest for securement within the automotive sill. A series of pockets for selective positioning of weights therein are formed along lowermost side and bottom edges of the arm rest to enhance positionment and alignment of the arm rest adjacent an exterior surface of an associated automotive door. A plurality of transparent message-receiving pockets are positioned parallel to the pneumatic chambers for receiving advertising and slogan literature therewithin. Further, flexible magnetic strips are fixedly secured to the interior surface edges of the arm rest for securement adjacent an automotive door.
