Posting this in Coffee Break as I know for some people it may be more a matter of opinion (personal) then anything else. At what age is a kid perfectly safe to sit in a decent booster with a three point belt, no harness. This is assuming the kid is responsible enough to sit still during the whole journey and you don't have any access to any high weight harnessing seats. I guess what I'm saying is, physical maturity wise.
