This is a set of an air footrest (with a bag and dirt prevention cover) and a back cushion. I purchased it on Amazon around 2023 and used it only once on a plane. I have confirmed that it can be inflated before listing. The air footrest is useful for long flights during overseas travel. It widens the seating area and allows you to raise your legs, making it very comfortable. It can also be used in a car. Children whose feet don't reach the floor or small children can lie down and sleep on it. Includes a floor dirt prevention cover and a storage bag. The following is the Amazon description of the footrest: --- Material: Polyvinyl Chloride (PVC) Color: Gray Dimensions: 38 cm length x 30 cm width x 43 cm height Brand: IFLY Size: Gray Item Weight: 0.4 kilograms
