3-Tier Footrest Convenient for Swelling Relief Color: Gray *Price includes shipping, so no price reduction is available.* I intended to use it, inflated it once with an air pump, confirmed there were no leaks, and brought it on a trip. However, the footrests on the seats were the type I needed, so I didn't use it and brought it back. It can be stored compactly and is very convenient for travel and long periods of movement. There are two air holes, and you can adjust the height by using one or two tiers. You can inflate it with an air pump or manually. Instant purchase OK ○
