You see this is again confusing - the Infasecure Comfi Caprice - I have been told by Infasecure today has a change to Booster marker of 45cm which is pretty high, and that weight is completely irrelevant.



So I don't know if that is true for all convertible boosters with the height markers but based on that I could in theory get DD (24kg) or DS (18kg) in it without it being in Booster Mode.

It is also quite illogical that weights are now not mentioned at all, the seats and harnesses must be tested with dummies of particular weights - I can't see how weight can be completely irrelevant, and because no weights are now shown anywhere you can't easily check if a particular seat is one of the height is the only thing that matters seats or if weight comes into it.
