My 5 month old is starting to look uncomfortable in his Besafe izi go car seat. He is a long baby and looks hunched up in the deep seat. I am not convinced it is safe anymore, the shoulder straps are at their highest and he doesn't look like he used to and I want to replace it. I am happy to get a 0+-1 rather than a group 1 if necessary.
My questions are:
The current seat is Isofix and I love the convenience, in the next seat which will be left in the car much of the time is Isofix necessary? I have read it isn't necessarily safer, but helps to avoid incorrect installation. Also, with my current seat I can use seat belts as well, is this the case with the next stage or do I have to choose?
I would ideally like the option of extended rearfacing, but to be able to use forward facing just in case. Does this severely limit my options? I thought I would go with the rearfacing besafe, but am not sure now. I have been looking at the Britax Dualfix Combination Car Seat which looks good, but a bit pricey at the moment tbh - I didn't think I would be switching yet, so hadn't budgeted for it.
I have seen some threads about seats that swivel to make it easier to fasten the child in, but some say it isn't as important with rear facing. Is this feature just a gimmick?
