Am I better to opt for a child restraint system with ISOFIX or for one that is secured by the car seat belt? Should I make ISOFIX attachment points a priority when buying a car? We look at the advantages and disadvantages of both so that you can choose which option best suits your requirements. The key to everything is how easy or otherwise it is for you to install a car seat.

This is because, in the event of an accident, for a child seat to operate correctly it is vital to have installed it correctly. This is the main problem many users come across with seat belts: the greater or lesser ease with which it secures the child seat correctly, always following the manufacturer's instructions.
