There are two ways to attach and secure a child car seat. On the one hand, the vehicle's own seat belt can be used. On the other hand, the ISOFIX anchorage system is available.
The first modality requires parents to ensure that the chair is perfectly secured and remains firm on the seat. For their part, ISOFIX anchors are the safest and fastest way to install a child car seat.
When choosing a child seat for the car, keep in mind both alternatives and their respective ease of use and installation.
