My 15 mth old grandson stands on this, so it is sturdy, he also picks it up and carries it, so it is a great size and weight for him and he has learnt how to raise the doors, so it provides him with challenges. He enjoys lying on the floor and putting the vehicles away and getting them out. He has the enjoyment of learning to use the press button and keys to come. I like that it is wooden, sturdy and contained.
