I have not actaully purchased this car seat however was interested due to it saying it could be used rearfacing which I plan to do with my child until she is 4. However I phoned up the manufacturer before buying to double check it could be used rearfacing until 18kg as it seems to state in the information. Unfortunately I was told that it is only RFing until 10kg and FWing until 18kg. I think the advertisement is pretty bad ans should state the exact weight limits like every other car seat.
