FAQ: Choosing the Best Car Seat for a 4 Year Old

All seats on this list meet federal safety standards. However, the Graco 4Ever DLX and Britax One4Life are top-rated for crash protection and ease of use.
Can I reuse my older child’s seat for my 4-year-old?
Only if the seat hasn’t expired, been in an accident, or been recalled. Always check the manual for expiration.
Are slim car seats safe?
Yes, seats like the Diono Radian 3RXT are both slim and safe—perfect for fitting three across.
Do I need a travel car seat and a home car seat?
