Recommend a HBB car seat for 4 year old please

[MrsNich]

We currently have the cosatto zoomi, he has reached the 18kg limit for the harness. I have taken the harness out and we have been using with seatbelt. However, the seat doesn't feel safe, it moves round a lot and feels flimsy. I have been looking at others including isofix but now i'm totally at a loss as to which to go to?
Any advice appreciated, thanks!

Niamh currently has the Joie Trillo (which is down to £40ish in Halfrauds). We really like it as it is Isofix and it's a nice seat position for her.

we love our recaro sport- super sturdy and quite heavy (which is fine as long as you don't need to switch it between cars regularly!)

We have the Kiddy Isofix HBB, highly recommend.
