Does anybody have a Streety Fix car seat (with the base that stays in the car). On the Bebe Confort website the base looks more slimline than the Creatis Fix base but I need to find out if this is the case and I can't find anywhere local that stocks one to test out in the car. I'm about to have my third baby and it's a bit of a squeeze on the back seat with 2 other children's seats so the slimmer the base the better. We have the Loola travel system and have found out that the Streety car seat does fit on the Loola chassis. Any advice hugely appreciated.
