My son (5) is very proud of his followers. It is stable enough also. At that age you can still easily into place and can be extended. But be careful, the trailer can not be ascertained, unfortunately. That is, it is easy to. Thus it naturally tilts backwards quickly. (Not the complete trailer but the bowl) Since a parking option would be worth improving. Since the trailer but not intended to be a child in the sets but to transport it objects does not count my objection yes really is. Beautiful stable part with a lot of fun factor.
