I use this when we go to bible study groups and camp meetings. It fits great in my Bible case and I just blow it up and no matter what kind of seats they have my back feels great. I hate those folding seats but, with this they don't bother me either. I also, use it at my computer desk for my neck. You can adjust the amount of air you need so, as to get the right view level to see the screen. So, many uses. The only problem I had with it was it does get holes in it pretty easy. You have to be very careful with it. Other than that I love mine. The blowup part just needs to be a bit thicker so, it would not get holes so, easy. I would recommend it to a friend.
