We had trouble with a car seat that was designed for smaller cars there fore it was a smaller seat. I didnt take into account that DH is 6'4 and I am tall as well in the reclining position for newborns she could jump off the back seat so we ended up turning her around alot earlier than I would of liked. We bought a SafeNSound for DH car and love it, all my friends have sns carseats and have never had problems.
Prams well that is another story 19 months and 5 prams and 1 stroller down I still havent found the "perfect" pram
