The construction lasted maybe 5 minutes.
As you can read in other reviews already, it is helpful, the screws do not tighten at first, as long as the rest is not plugged in. Then the assembly is easy.
We liked that the highchair is supplied complete with table and cushions. The cushion is in duplicate, so that can be washed in turn.
The chair seems stable, the workmanship is good.
We are satisfied with our purchase and would buy the highchair again.
