    BabyGearLabHands-on review · 2024

    Ranked 19th of 24 with an average-at-best score; belt install with the lock-off is easy, but crash test results are below average and the hook-style LATCH and harness tightening are frustrating.

    Good HousekeepingNo printed score · Buying guide

    Picked as best overall all-in-one car seat for easy installation, many recline positions and a long rear-facing and booster range.

    What to ExpectNo printed score · Buying guide · 2026

    Picked as the easiest convertible seat to install thanks to its audible click system, and it lasts from newborn to booster.
