This has been a great item for car and airplane trips. My daughter has all that she needs in her reach and it all stays contained around her so no picking up fallen crayons or cups!  There is a strap that you can buckle around the child so they can’t accidentally drop the tray off their lap. Fold up quickly and fits great in a diaper bag or backpack. I have seen where you can slid a tablet in and strap it to the back of the front seat and they can watch movies/shows. Have not tried this as we limit screen time but a great idea!
