Improved version. Introducing a new separate type that does not hold both feet. Reduces burden on your feet and reduces swelling. A convenient airplane travel item! Even during long flights, it can be placed on the sole of your feet and calf to maintain a relaxed posture. The five plates prevent the shape of the plate and can be used comfortably for a long time. Easy to install, just hook it to the table of your seat. Height can be adjusted with the length adjustment belt. Folds up compactly and stores in a dedicated bag, making it easy to carry. Can be used on airplanes, high-speed buses, and bullet trains. Makes a great gift for your loved ones who love traveling.
