Thermos Back Seat Car Organizer - Premium Insulated Cooler for Road Trips, Picnics & Outdoor Adventures

As other reviewers mentioned, the sides don't stay up unless there is something inside. I really wanted to use this as a cup holder for my daughter as there is no cup holder on her car seat. I put cardboard on the inside to make it stable and that did work. Another comment was that the cup holders were very small and unfortunately they are. She has a couple of tumblers that fit perfectly into the holders, but any other thermos type cups or juice boxes will not fit. I was disappointed in that. Needless to say, it is not serving the purpose I had intended it for and I cannot see it being practical for the purpose it is advertised for as a can of soda barely fits into the cup holder. Apparently these are selling elsewhere for half the cost as well.
