My son was so excited to see this Cozy Truck and couldn't wait for daddy to put it together. The assembly is a little difficult but not any more difficult then other toys made out of similar materials. Once it was put together my son jumped in it and played until we made him stop. His absolute favorite part is the tailgate and truck bed. He loves opening and shutting the tailgate to load up his toys. Having a door that opens and locks is awesome. This is a great toy that my son will use for years.
