I've just been at a car seat checking event and on discussing my options for a new seat for my soon to be 4 yr old DD I've been told that I should look for seatfix rather than isofix as the new thing. Apparently it allows the seat to move out the way on impact rather than holding it rigid. I had thought that i would get the Ferofix but they were suggesting Recarro, kiddy or concord as better makes with side impact testing as standard.
Does anyone know more about this. I can't find much info on the Internet.
