We have a trip planned flying out and renting a Toyota RAV 4 at our destination. My child is about 49 inches tall and 47 pounds, and rides in a high back booster at home. I am trying to decide on safest choice for travel booster. I’ve seen Cosco rise as a choice and possibly the inflatable bubblebum, don’t know if there are other options? Thanks for any help!
