Do you love your convertible car seat? If so, you can nominate it for a 2013 About.com Readers' Choice Award for Best Convertible Car Seat! The best convertible car seats have a wide range of safety and convenience features, and have high enough height and weight limits to accommodate your child for a long time, particularly for extended rear-facing. Great car seats are also easy to use, so that parents are less likely to use the seat incorrectly. Let us know which car seats you think are best. Do you have a spare that you love, as well? You can nominate up to three convertible car seats at a time.
