0+ stage car seat? saw it in john lewis the other day and the base looks pretty narrow, which could be a bonus as need to fit baby seat, booster seat and high back booster in as well. the only thing thats putting me off is the price tag. i know you cant put a price on safety etc, but £180 for soemthing i cant sell on really, and could only be used for 6-9months based on dd2 size. why cant they make a 2 stage car seat with isofix for the same price? once bubs outgrows this one then i'd need to buy another.
