And solid. 2 and a half years later, the stroller is like new.
The stroller is designed for smaller, first steps until about 4 years. For my 4 ½ years we see that it has become small and it would not hurt to buy a larger (but that does not stop him from using it).
Only downside: the seat of the stroller sometimes landed and must be put in place (it takes a few seconds).
The stroller folds / unfolds but I have no opinion on the system because I never folds.
