Convenient goods to reduce the burden and fatigue on the legs and hip joints caused by long-distance travel on airplanes, bullet trains, buses, etc. Easy to install, just hook it onto the front seat table of airplanes, bullet trains, express buses, etc. The length of the belt can also be adjusted, making it easy to change your posture and prevent you from staying in the same position for a long time. I bought it for a night bus and brought it once, but I couldn't install it on the bus seats, so I haven't used it. - Color: Black - Size: Approximately 40cm x Approximately 19cm - Weight: Approximately 79g - Storage bag: Comes with a storage bag Please note that there may be slight errors due to amateur measurements.
