We received a car seat for my toddler from a friend (used by her dc previously). The seat is only fixed by a seat belt and doesn't have Isofix.
We followed the instructions fitting the seat in the car but it really wobbles when we try to move it around without much force.
Is it normal?
Is it safe?
We ever only used Isofix seats before and we are quite concerned despite it would be in our second car, whch we don't use much with kids but still...
