- Rear-facing longevity: If possible, choose seats that extend rear-facing use to maximize safety for younger children and longer road safety benefits.

- Compatibility with multiple vehicles: Consider seats that are known to fit well in a wide range of cars, SUVs, and minivans to simplify carpooling and travel.
