Infant car seats. Infant car seats are rear-facing seats that are for babies up to 22 pounds. They allow infants to recline at an angle that doesn't interfere with breathing and protects them best in a crash.

Travel systems. Travel systems offer one-stop shopping: You get an infant car seat and a stroller all in one.

Convertible seats. With a convertible seat, the child faces rearward as an infant, then toward the front of the vehicle as a toddler. The seat can function as a rear-facing seat for infants up to 30 or 35 pounds, depending on the model, and as a front-facing seat for toddlers generally up to 40 pounds (a few have a 65-pound limit).

Strollers. A stroller is a small vehicle with four wheels in which a baby or child is pushed around.

Booster car seats. A booster car seat is a seat to help raise a child in a vehicle so that the vehicle’s seat belt fits properly.
