- Safety standards and testing: Prioritize models with proven testing standards and protective engineering like Graco ProtectPlus or equivalent.
- Legroom and comfort: Features like extended rear-facing legroom or adjustable extension panels can improve comfort on long trips.
- Cleaning and maintenance: Removable, machine-washable seat pads and dishwasher-safe parts ease upkeep for busy households.
