Review on Portable Inflatable Travel Foot Rest: Adjustable 3 Layers, Double Hand Pump, Gray by Tim Arnold

Not suitable for car use. I thought they would help my kids who are in boosters feel less stressed when they are in the car on a long drive. They just stunk in the car (they have a very strong plastic smell) and made the kids feel cramped, although I tried different levels of inflation to get more or less height. Nothing worked, so they just took up space in the back of the car while driving. I think it would make more sense to have something solid. Their pillowy nature is part of the problem. They were also difficult to inflate in the car and difficult to crawl between the seats once inflated. I would have thought they wouldn't fit between airplane seats either, but I haven't tried them for air travel.
