safe n sound meridian tilt and adjust  convertible carseatConvertible carseats are both forward facing carseats and rear facing car seats. These seats can be changed from rear facing to forward facing ie TYPE A/B child restraints.

Convertible car seats can include extended rear facing (A4) car seats, which allow child to travel in rear facing mode for an extended period of time (till approximately average of 30 months.)

Once again understanding what the height markers mean is key to ensuring your child is in the correct car seat for their age and height.

A2 Convertible Car seat Height Markers

A4 Kompressor Shoulder height markers
Other Convertible carseats may be referred to as A2/B carseats This means that the car seat has been tested to at least a average 12 month old. Unfortunately there is no standard where the lower or upper height marker should height marker should be, but there are minimum standards.

The upper height marker indicates the maximum shoulder height for a child in the restraint. When the child’s shoulder is at the top marker they are ready to move to the next type of restraint.

The lower height marker indicates the minimum shoulder height for a child before they can be turned around to a forward facing position. If the child’s shoulder is below the marker they should remain rear facing.

For an A2 convertible child restraint this marker is a minimum of 35 cm

A4 Shoulder Height Markers

Th A4 child restraint is in 2013 Australian Standard, which was finally approved on 17 September 2014. The A4 Car seat is a car seat which has three shoulder height markers the lowest marker indicates that you can turn your little child forward facing however you can leave your child rear facing until they reach the middle shoulder height marker.

The highest Rear Facing Should height marker should be at 39 cms. However there are some car seat manufacturers which do not have the second should height marker for rear facing at 39 cm, these being the Maxi Cosi Euro and Maxi Cosi Hera which have the second marker at only 37 cm.

This 2 cm difference would mean you would need to turn your child at an earlier age than manufacturers which have a marker height of 39 cm (i.e. Infa Secure and Britax)

It should also be noted here that Maxi Cosi needed to recall their original A4 car seats as they were not certified by SAI Global.
