Exclusive Guide to Rotating ERF Car Seats

Guide to Rotating ERF Seats


We recommend rear facing to at least 4 years old (preferably more!) and harnessing to at least 4 years old (even if forward facing), so if your child is on the upper percentiles for weight or height, we’d recommend getting a car seat that rear faces to 25kg as they will better accommodate a larger percentile child.

Q: Why is the Maxi Cosi Axissfix not on here?

A: The Maxi-Cosi Axissfix can only be used rear-facing until the child is 87cm tall, which is around age 2 for most children, and therefore we don’t recommend it unless the child is on the lower centiles for height and would last to at least age 4 in it.


Bear in mind that rotating car seats are often not very tall, and can be outgrown early by height even though they all have a weight limit of 18kg to 19.5kg.
