I've been looking for ageeees for a pushchair/buggy/travel system whatever they're all called and am still no closer to knowing what I need. I don't drive so need a collapsable one for the bus, but can have one with a car seat as my fiancé does. I walk a lot, both on smooth pavement, in town and on normal gravel. Does any particular brand spring to mind? Any opinions/help would be much appreciated! x
