I've been looking at this too, although mine are slightly older. That height/weight you'll be on the border of a group 1 or 2 car seat, and I would suggest a group 2 as it'll have more longevity, or get one that covers 1/2/3 and grows with the kid. I'm considering a Joie or a Cybex, but waiting for the car to arrive so I can go and check. You might want something to protect the seat too
