Infant seats are rear-facing only and portable. Convertible seats go rear-facing then forward-facing. All-in-one seats add booster mode. Boosters are for older children who have outgrown a harness.

A convertible car seat converts between rear-facing and forward-facing orientations in the same shell, unlike an infant seat that only rear-faces and detaches from a base. Some convertible seats, like the Graco 4Ever DLX, also convert into a highback and then backless booster, which is why they are sometimes called all-in-one or 4-in-1 seats.

There is no single age. Pediatric safety groups recommend keeping a child rear-facing until they reach the seat's maximum rear-facing height or weight limit, which for the seats in this list is 40 pounds. Many toddlers reach that weight limit well after age 2, which is why current guidance emphasizes the seat's limits over a fixed birthday.

Car seats have an expiration date printed on a label on the shell, typically 6 to 10 years from the manufacture date. Heat and UV exposure over years can degrade the plastic shell and harness webbing, so manufacturers set an expiration date even if the seat looks fine. Check the label rather than assuming a seat is safe based on appearance alone.

Most infant car seats fit from 4 pounds, including the Chicco KeyFit 35 and Evenflo LiteMax 35, which both accept babies starting at 4 pounds with the included infant insert. Convertible seats like the Britax Boulevard ClickTight and Graco 4Ever DLX start at 5 pounds. If your baby is expected to be born under 5 pounds, or arrives early, check with your hospital's car seat program or a certified child passenger safety technician before your due date, since some preemies need a seat rated specifically for low-birth-weight infants.

An infant seat (Chicco KeyFit 35, Evenflo LiteMax 35) is the more common choice for newborns because it detaches from a base and doubles as a carrier, which matters for stroller travel and letting a sleeping baby stay asleep. A convertible seat (Graco 4Ever DLX, Britax Boulevard ClickTight) stays installed in the car permanently and lasts years longer, but it does not detach, so you carry the baby in your arms rather than the seat. Many families buy an infant seat first and move to a convertible seat around 12 to 24 months when the baby outgrows the infant seat's height or weight limit.
