The Guardian Pro 2 is the latest Group 1,2,3 car seat from Kiddy featuring their impact shield. We have permanently changed to using this car seat as our daughter finds it really comfy. I love it as it is so light and easy to take to my parents, or even on holiday (by plane). Because it is a Group 1,2,3 it can be used from 9 months right up until your child no longer needs a car seat. After Group 1 you dispense with the impact shield and just use the normal adult belt.
