- Installation and harness adjustments: Seek seats with easy, intuitive setup and harness height adjustments to reduce installation time and improve safety checks.
- Maintenance: Removable, machine-washable covers and dishwasher-safe components help keep seats clean between trips.
- Safety standards: Ensure the seat meets or exceeds applicable safety standards and includes side-impact protection.
- Travel readiness: For air travel, consider seats with FAA approval and compact folding options or bundles that include carry bags.
