Professional reviewers are enthusiastic about the Britax Boulevard convertible car seat, and parents give it excellent feedback as well. The standout feature here is the safety wings with EPS designed to provide additional protection in a side-impact collision. Some reviewers do express concern that the wings block the child's view too much, so if you're considering the Boulevard, it might be a good idea to see how your particular child reacts to it first. The Britax Boulevard also gets good reviewer feedback for its extra-high weight limit. While most convertible car seats -- including the popular Graco ComfortSport (*est. $90) -- are only rated for kids who weigh less than 40 pounds, the Boulevard can accommodate children weighing as much as 65 pounds in a five-point harness. The Boulevard is bulky, though. The Sunshine Kids Radian65 (*est. $200), which has a steel alloy core, is much narrower and folds up for transport.
