Easy to carry, compact portable footrest Footrest Swing For use on airplanes, bullet trains, etc. Can be used on vehicles with tables. You can spend long journeys very comfortably. Used only once, in excellent condition. I bought it for long-haul flights on overseas trips, but I am selling it because I no longer have the opportunity to travel due to pregnancy. It was very comfortable for year-end and New Year's trips, and for long-distance flights!! It's compact, about the size of a folding umbrella, and a convenient size to carry around! Instant purchase without comment is welcome!
