For my daughter almost two years that you want to eat at the table and not in his high chair, no need to pad it is installed, stable at the right height, and safe.
The fasteners that secure the booster to the chair are easy to install, less to remove (it is regrettable that the belts are not clipped). So it is left in place and only occasionally remove it for example on holiday.
Plastic is strong, the colors are very beautiful, I am delighted.
I find the excellent quality / price ratio.
