Britax Poplar Convertible Car Seat

Ride with confidence from baby to big kid with the Britax Poplar Convertible Car Seat. Designed with innovative safety and space-saving features, this seat simplifies every stage of your child’s journey. The patented ClickTight® installation makes setup virtually foolproof—just open, thread, and click for a secure fit every time.

With its slim 17-inch SpaceSaver™ frame, the Poplar fits 3-across in many vehicles without compromising comfort or safety. SafeCell® technology, a carbon steel frame, and a patented V-shaped tether work together to absorb crash energy and minimize movement during impact. The 14-position headrest and harness adjust effortlessly as your child grows, while the 6-position recline ensures a comfortable fit in any vehicle. Naturally flame-retardant fabrics contain no added FR chemicals and are machine and dryer safe, making cleanup easier for busy parents.

Whether rear-facing or forward-facing, the Poplar keeps your little one safe, snug, and ready for every adventure.
