We bought this for our 2 year-old grandson. He absolutely LOVES it!! Since he's so young, we keep the car itself inside the garage so he can't use the coaster without adult supervision. We haven't shown him he can climb up the coaster and that helps also that he doesn't try it alone....although I think he would be fine. I wish you could hear/see him laughing and screaming with his hands up in the air when he rides it. Best gift so far. :-)
