Abstract: A resilient accessory to be used as a cap for the arm rest of a seat, specifically a passenger seat on an airplane, bus, or other carrier. A lower rigid base member is provided having suitable mounting tabs for attachment to a passenger seat. An upper resilient member is positionable over the base and has a pair of lower edges for enveloping and retaining a pair of rigid angled strips. Air pockets with a suitable support spine and partitions are formed within the upper resilient member. The base is spot welded or glued to the angled strips. In an alternative embodiment, the base member includes lower side edge walls which are enveloped by the lower edges of the upper resilient member for retaining the upper resilient member and base in position. Suitable filler material may be disposed between the base and the upper resilient member for providing enhanced padding. The upper resilient members may be formed by injection molding according to the desired specifications about the base member.
