Wide seat width, to the point that it makes it very difficult to fasten the seatbelt! An extension had to be added to the buckle of the seatbelt for it to close.

My rating is purely about the comfort of the seat. As for quality, apart from the plastic isofix arms, it is of good quality. Unfortunately, the seat is not soft or comfortable at all. Our little one has said that she doesn't sit comfortably, and indeed the seat doesn't have a cushion for the child to sit comfortably. I do not recommend it, and fortunately, I did not buy a second one. I will look for something else.

Very good seat and stable. You must definitely get a booster with isofix! We saw other kids with boosters using a seatbelt and they offer no safety in case of an accident, just elevation and convenience with the seatbelt. With isofix, you are sure.
