Not only this can be used in the vehicles but it also works amazing for my 3 year old wheelchair. He doesn't have control of being able to keep things in front of him but this tray and tablet holder is everything. I will be purchasing another for him to have at school also because his chairs need this product but more than ever it has kept me from having to constantly pull over to pick things up for him due to falling from his hands. This is the most useful product of all time And I tell many families about it.
