This is amazing!!! We got it for our 18 month old and 5 year old. It is very safe! My little guy could do the entire process by himself at 20 months. Huge hit for kids up to 10 (maybe beyond). Also, it is great exercise! Kids have to push the cart up by themselves (if they live in our home:)). Sooo fun! We also gifted one to my cousinâs kiddos. Beware, though, once it is assembled, it stays assembled unless you pull out tools!
