Jordie - I highly recommend asking Baby Bunting (or wherever you go) if you can take out different car seats to your car to test them out. You will find any Safe N Sound brand is safe, they exceed the Australian standards and to be honest the are all pretty much the same, just with different covers! (Trust me, I have washed many a seat cover!) You will find most convertible Safe N Sound car seats will have the Active Head Restraint (AHR) so don't let the sales person tell you the Meridian is the only one. Good luck in your quest!
