Is it a requirement that group 0 car seats have them?
DH got an old Britax one secondhand when DS was younger to use as a spare in his parents car and we were going to use it for this baby too. Thing is i've had a look at it and realised its only a 3 point harness, not 5 point. I don't really feel comfortable using it on a regular basis because of this anyway but was just wondering what the safety standards were? I couldn't really find anything from google.
