Aha- if I am not mistaken, Britax is the only company that makes seats that go up to or over 60lbs. Most max at around 40 lbs. At around 40 lbs children can usually move into a booster seat. That being said what you might want to look for is a seat that works rear facing, forward facing, and also converts into a booster. Evenflo alpha-omega is a great example of such a seat. Still not understanding what would be easier, to have to climb all the way through the car to get the child out from behind the driver's seat if entering through the right side of vehicle(passenger side) or to simply open the door and have the child sitting immediately infront of you on the passenger side. Either way, like I said it is a personal decision, just a differing view point.
