Apologies for not being clear, I blame it on the wine
Almsot all Swedish toddler seats rear face until 55 lbs. A few of them can be used as combination seats, but still rear face until 55 lbs. In Europe, it's very uncommon to have seats forward face with a harness above 40 lbs. The Two-Way is one of those seats, I don't know of another one.
The combination seats are usually used rear facing longest possible time, about 4-5 years, and then forward facing as a BPB. A good example of this would be the new and awesome Multi Tech. Rear facing until child grows out of the seat, usually by height, and then used as BPB until 55 lbs. That usually means 7-9 years of age. There are no seats here which harness children for higher weights since experts here believe it's less safe.
Rear facing a 12 month old instead of forward facing is about 500% safer. That's a a pretty large number, it makes a difference and saves lives. For me, it would be a no brainer. My son sat rfing until 4 years of age and I hope my daughter makes it until 5 (she's 2 now). I would use a Swedish seat regardless of location but that's a personal preference. Everyone makes their own decision and I totally understand those using other solutions.
