Axkid Minikid ERF (Extended Rear Facing) our 3 and a bit year old is still happily sitting in his and the 19month sits fine in his as well.
We use mirrors to keep an eye on them/ interact with them.
They are expensive – but dont need ISOFIX.
If you do a bit of searching about ERF the vitriol is horrendous.. people saying if you dont do it you are killing your children..
They quote lots of stats (all about head on collisions, they dont talk about sideways and rear end collisions.
I was really well accepted into these online communitys when I told them that their children would be safe if they all stopped crashing their cars head on into other cars/things… ok maybe i wasnt but just saying.
When you actually look at the actual science behind ERF recommendations I do wonder why the heck we are all not rear facing in cars.
Moving onto swivelling the minikids do not swivel but they are easier to get the children into by nature of being rear facing the door allows for it.
One last thing if you have long legs and push your seat far back this seat might not work for you – our Ocatvia and my stupid length legs only just fits the seat.
Paul Stride in York were really helpful fitting a test model so we could be sure it worked for us. (I was hopinh it wouldnt and we could get a new car!!)
HTH (I used to look at shiny new bikes online!)
