I'm trying to find a high back booster to fit between an infant carrier and another high back booster as I'm not ready to move my eldest to a booster with no back.
I've seen comments that a britax adventure would be one of the narrowest available. But the closest shop stocking it is over half an hour away. Does anyone know if 43cm width they refer to is the seat itself (where the child sits) or the whole car seat? Also is it wider round the head? I'd be so grateful if anyone can help.
Thank you
