Is the Chicco KeyFit 35 Infant Car Seat worth it?

Yes, for the right buyer. The Chicco KeyFit 35 Infant Car Seat ranks #1 in our Best Car Seats for Newborns list (top pick). Its biggest strength: belt path routing on the shell itself means the seat installs without its base in a rental car. The main caveat: heavier carrier than the LiteMax 35, more tiring across a long terminal walk.

Overview

What the Chicco KeyFit 35 Infant Car Seat does well

Best overall newborn pick. What earns it a place here: fits from 4 pounds with the included insert, one of the lowest starting weights of any infant seat and consistently rated one of the easiest infant seats to install correctly on the first try. Keep in mind that height limit around 30 inches means many babies outgrow it before 35 pounds.

Best infant seat pick for small cars. What earns it a place here: one of the shallower infant seat bases available, which helps in short rear seats and load leg design reduces how far the base needs to recline compared to bases without one. The tradeoff: still needs a proper recline angle, which can push the front passenger seat forward in very small cars.

Best for consistency. Its case rests on belt path routing on the shell itself means the seat installs without its base in a rental car and widely reported as producing a correct install on the first try, useful when rushed at an airport counter. Keep in mind that heavier carrier than the LiteMax 35, more tiring across a long terminal walk.

Buying advice: car seats

  1. 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.
  2. Experts recommend keeping children rear-facing as long as the seat allows. Higher rear-facing weight and height limits let you do that for longer.
  3. Look for clear level indicators and lock-offs or tensioning systems that make a tight install easier. A seat that is hard to install is more likely to be installed wrong.
  4. Measure the back seat, especially for compact cars or three-across setups. Rear-facing seats can push front seats forward.
  5. Car seats expire, usually 6 to 10 years from manufacture. Check the date and never use a seat that has been in a moderate or severe crash.

What does a convertible car seat mean?

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.

At what age should a child switch from rear-facing to forward-facing?

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.
