My DD, 4 yrs 8 months, is asking to go ff and as we swap her ERF Britax TWE regularly and it's a faff I think we will buy a HBB and use her ERF for longer/ motorway journeys.
However I am now utterly confused. What is the difference between a cheap and cheerful Britax Adventurer and a hugely more expensive Jane, or BeSafe HBB?! Are they performing significantly better in crash tests?
