Ranked #4 in Best Convertible Car Seats

Britax Poplar

4.1

$379.99as of Jul 7

The Britax Poplar is a narrow convertible car seat designed for vehicles with limited space, featuring Britax's ClickTight installation system that simplifies belt-based installation. Reviewers noted its lightweight construction and anti-rebound bar for rear-facing use, but criticized its average crash test performance, particularly in head sensor results. While it installs well in most vehicles and offers good comfort and quality, some reviewers found the harness system difficult to use. The seat is recommended for families needing a compact option, though those prioritizing top-tier crash protection may want to consider alternatives.

Strengths

— Narrow design allows for easier installation in tight vehicle spaces
— ClickTight lockoff installation system is easy to use with vehicle seat belts
— Lightweight at 26 pounds, making it easier to move around

Graco Extend2Fit Convertible Car Seat

4.6

$239.99as of Jul 7

The Graco Extend2Fit convertible car seat earned impressive crash test analysis results with some of the lowest sensor data in the test group, indicating better protection than average. Reviewers noted its simple LATCH installation with push-in connectors, comfortable design, and lightweight build at 18.5 pounds. The seat offers a 50-pound rear-facing weight limit and includes features like extra legroom and multiple recline positions. While it has better-than-average crash performance and ease of use, it lacks a belt lock-off and has a one-sided bubble indicator. This makes it a solid value choice for parents seeking extended rear-facing capability and good safety ratings.

Strengths

— Better crash test results than average with low HIC and chest clip sensor data
— Simple LATCH installation with push-in connectors that are easier to use than hooks
— More legroom for kids and potential for longer rear-facing use

Watch-outs

— No belt lock-off feature for LATCH installation
— Bubble indicator is one-sided only

How they stack up

Britax Poplar

The Britax Poplar stands out for its narrow design and ClickTight installation system, making it easier to install in tight spaces compared to the Graco Extend2Fit, which lacks a belt lock-off feature. However, unlike the Chicco Fit360, it doesn't offer 360-degree rotation and has below-average crash test performance, particularly in head sensor results. While it's lightweight and user-friendly, it falls short of the Nuna Revv's comfort and the Britax Poplar S's three-across suitability.

Graco Extend2Fit Convertible Car Seat

The Graco Extend2Fit outperforms the Nuna Revv in crash test results and offers better legroom and extended rear-facing use, unlike the Nuna Revv which has lower safety scores. While it lacks the 360-degree rotation of the Chicco Fit360, it provides superior ease of installation with push-in LATCH connectors and better overall safety performance. Compared to the Britax Poplar and Britax Boulevard ClickTight, it has better crash test data and a more user-friendly harness system.
