Buying tips

When selecting a car seat cushion or seat, consider your child's age, weight, and height, as well as your vehicle's compatibility. Look for safety certifications (FMVSS 213), ease of installation (e.g., ClickTight or SuperCinch), and adjustability features like multiple recline positions. Remember that an infant seat is more portable but convertible seats offer longer use. For tight vehicles, narrow seats like Diono Radian are ideal. Always check the expiration date and avoid used seats with unknown crash history.
