Sunshine Kids Radian65

The book "Baby Bargains" has by far the best review of the Sunshine Kids Radian65 convertible car seat. Authors Denise and Alan Fields include the Radian 65 in their extensive roundup of car seats. While there's no independent testing done in this book, the authors do an excellent job of considering factors like parent feedback, features, value and brand history. The Sunshine Kids Radia 65 also gets good coverage from parents posting to user review sites.

The Sunshine Kids Radian65 convertible car seat gets enthusiastic feedback from reviewers, primarily because of its innovative fold-up feature. Another plus is its high weight limit: It accommodates children weighing up to 65 pounds in a five-point harness. The Sunshine Kids Radian65 is made from steel alloy rather than the usual plastic. The upside of this is that the Radian has an unusually narrow profile and fits well in most cars; the downside is that it's quite heavy (20 pounds), meaning that not everyone considers it portable. If you don't need the fold-up feature, the top-rated Britax Boulevard (*est. $300) also has an extended weight limit.
