The Emblem Convertible Car Seat is safe and comfortable for your growing child while you’re on the go. Car seat installation is a breeze with push button LATCH connectors and built-in lock-offs.

Plus, foam padding and two recline positions keep your b aby comfy and cozy along the way, while the 10-position easy-adjust harness and headrest allows you to never have to rethread again.
