DH has just written off our car, and we need to get new car seats. I'm after help with options for DS2, who is 2. He was in a GB Vaya i-Size - a swivel seat which is basically the same as the Cybex Sirona, and that was fine, but he is 90th centile for height and weight, so would likely outgrow that in just over a year or so, therefore we'd like to get something that will last a little longer - 25kg at least. However, while we'll be keeping him RF for now, and ideally until 4 (DH is illogically against RF, though is keeping quiet currently seeing as he crashed the car with both kids in it), I would like to have the option to go FF at some point. I've looked at a few seats on the In Car Safety Centre website, but haven't found much that will do this - the Britax Two Way does, but then the harness is only to 18kg when FF.
Any ideas? Bonus if they're stocked at Halfords as that's where our insurers want to get them from.
