I was wondering whether anyone had some recommendations/experience: DP and me do not own a car (city dwellers), but for the couple of times we take a cab, rent a car, or go anywhere with a friend's car we have always owned our own car seat for DC. They've now outgrown their original MaxiCosi iPebble which I loved, cause it was easy to carry around and install in any vehicle.
Obviously car seats for toddlers and up are much bigger/heavier, but I was wondering whether anyone had recommendations on any models that make installing/lugging them around a little bit easier than average.
I've liked the "Joie Stages FX" model, and the "MaxiCosi Beryl", but am rather unsure whether they are at all reasonably fast to install safely, and how horrible it will be to carry them if necessary.
