This is a footrest that was #1 on Amazon's bestseller list. I bought it for travel, but I didn't use it, so I'm selling it. I haven't even opened it to try it out. I definitely bought it on Amazon, but I cannot be held responsible for any slight differences in the product. I've attached the images from the purchase site. Reference price: ¥3980 Quoted from the following site: ・Can be used as a footrest for children on airplanes. Using a footrest on an airplane seat is convenient for effectively preventing swelling and fatigue in the legs. By adjusting the seat flat using the footrest, it can also be used as a bed for children. ・Easy and quiet inflation. With the uniquely developed storage bag integrated air pump, you can inflate it in as little as 40 seconds. The large air hole with a check valve allows you to inflate and deflate the air instantly. Furthermore, it is quiet, so you can use it without worrying about those around you. ・Height adjustable footrest for cars. The height can be adjusted in 1, 2, or 3 stages, and because it is an air-type design, you can adjust the amount of air to fit various places, and you can also adjust the firmness to your personal preference. It is convenient to use in cars, buses, and bullet trains, as well as as a chair while waiting for a flight. ・Convenient size for storage and portability. When stored, it is as compact as a plastic bottle. It comes with a convenient storage bag that also functions as an air pump, and it has a buckle so you can hang it on a backpack. ・Comfortable material. The surface is flocked like velvet, which feels good against the skin and prevents stickiness. JON TORUDO is a brand planned in Japan, and our air footrest has a high durability of up to 70kg. Notes: When using it on airplanes or bullet trains, please follow the instructions of each management company. There are safety precautions.
