It's a very basic and easy concept. You assemble it and the track actually has steps that your child can walk up. They place the car in wheel wells at the top of the track and then they can push themselves off and roll down the track.Pros- Made in the USA! Great design, very durable, Car design is great - it has slots for a seatbelt and footrests and it's very sturdy! Definitely the best there is and happy with our purchase !
