For example, I’m not sure that I’m a little bit tired of having a baby seat. Why? 1. the problems of a non-Volvo Isofix seat are still quite well known to me, but the fact that I’m a little tired of having a baby seat for children from 9kg to 18kg. 2. my son has now reached the threshold to the integrated child seat (97cm and 15kg, 3 years), at least according to Volvo. So I bought the cover with a side pölster and headrest. When I took it away, it turned out that the headrest is far too high, which was commented by the dealer with the words, “that’s only for sleeping and not as protection!” My humble view as a doctor needs a 3 year old child in a serious side crash very well a support of the head! In addition, when sleeping, my child seat is always worthless because the rest position of the rear seat does not offer enough comfortable sleeping position to me, and a small child needs to sleep in the car. The belt is dangerously close to the neck.
