I am totally in love with this highchair.
It is foldable, it is very light, it fits under the table with its front part giving a small space consumption, the tray is big and the locking system works extremely well, the seat position is quite straight and the baby feels well supported. You can adjust the height very easily. It is totally stable.
Above all the features the quality is excellent in everything: materials, finishing is perfect.
It is not an economic product, but neither a very expensive one, and it is one of the cases in which you relly get the value of what you pay.
PS My baby is 10 months, we are using the highchair since he was 6, it looks like we just took it out from the box.
