Any isofix 2-3 car seats with a harness?

[FatherJames]

Hey

We are trying to get a new seat for our 3 year old that is easy to swap to the grandparents car safely (so far the 2 seat belt ones we've tried don't always get fitted properly).

We want a 5 point harness as that is supposed to be safer.

Also we'd like if possible to get a reclining seat.

Any recommendations?

I think we've decided to go with the Be Cool Thunder in the end as it covers the above and it's not huge like everything else seems to be:

Britax Advansafix does everything you want. Not sure how it measures up though.

Don't know if we cross posted Dixie, the Britax one can be used until 25kg with 5 point harness.
