Ranked #4 in Best Convertible Car Seats

Britax Poplar

4.0

2 sourcesall derived$399.99as of Sep 25

The Britax Poplar is a narrow convertible car seat for vehicles where space is tight, and its ClickTight system takes the guesswork out of belt-based installation. Reviewers noted the lightweight construction and the anti-rebound bar for rear-facing use. It installs well in most vehicles and the comfort and quality hold up, though some reviewers struggled with the harness system. Families who need a compact seat should consider it.

Strengths

— Narrow design allows for easier installation in tight vehicle spaces
— ClickTight lockoff installation system is easy to use with vehicle seat belts
— Allows rear-facing use up to 50 pounds or 49 inches tall, so kids can stay rear-facing longer

Watch-outs

— Harness headrest does not move smoothly and release button has strange design
