Abstract: A multi-component seat armrest that is particularly suitable for use in connection with vehicle seats. The seat armrest includes two basic interconnectible shell members. These interconnected members have portions that are sized and shaped to fit into portions of a third member called an insert member. The insert member has an aperture extending through it and an armrest panel is provided that is adapted to fit into this aperture. The armrest panel is removable for cleaning or it can be removed and interchanged with a different type or color panel. The armrest is particularly adapted for use in connection with aircraft seats where it would serve as the armrest for the end of the seat located near the aisle of the aircraft.
