I'm assuming Isofix is safer or is it same same what's the pros and cons ? I've a lot of research still to do to educate myself yet but I am considering the Avionaut pixel pro . I joined a Facebook group on car seat safety and this is what was recommended time and again it can be used with isofix or seatbelt . I'll be buying an isofix base. But wiuld like to know what the difference between using the isofix base and a seatbelt for the car seat is .
