Have you had a look at BeSafe? We had their isoFix RF, which was great, but looks as though they do up to 4-5yo RF in belted too.

The besafe izi kid does, it's up to 18kg and I think there's now a plus version up to 25kg. We've been very happy with ours as is our child.

The britax two way elite should meet your criteria too and we would definitely recommend it.

I have an Axkid minikid that is ERF belted to 25 kg

The added advantage of belt-fixed seats is that they have a weight limit for the child of 25kgs, and usually a longer backrest. So if your child is tall/heavy for their age they are not going to get to 4 years old in an ISOFIX seat anyway, you'd be better off with a seatbelted one.

ISOFIX was only invented as a simpler method of fitting child seats, not a safer one.

Just to mention, it is (I think) possible to have isofix fitted - but I'm not recommending it. Isofix won't hold unlimited weight, and there isn't a universal weight they all test to (in the way that group 1 car seats go to 18kg, etc) so I don't think you'd want a 4 year old held in solely by isofix. For example, for high back boosters with isofix the isofix will only hold in an empty car seat. If you crash with kids on the seat, the adult seatbelt does the work. Hope that makes sense - not sure if it does!!

Thank you so much! Yes that makes perfect sense 4yonid. I think it would be a bit of a hassle getting it all installed anyway to be honest.

We have the Britax 2-way Elite, which we use rear-facing. Well actually, we have two!
