About narrow car seats
These seats list a width of 17 inches or less at the widest point. A narrow seat makes three across, or a car seat beside a booster, more likely to fit in a smaller back seat. Fit depends on your car and how the seats overlap, so measure your back seat and try a test install.

From NHTSA
From NHTSA: "Your child under age 1 should always ride in a rear-facing car seat." Stay rear-facing "until he or she reaches the top height or weight limit allowed by your car seat's manufacturer." (NHTSA) Find a certified Child Passenger Safety Technician through NHTSA. Check the label and the maker's instructions, and ask your pediatrician about your child.
Questions about narrow car seats
Answers come from each maker's published specs. Safety and health questions link to the agency or medical source.
Are expensive car seats worth it?
Every car seat sold in the US must meet the same federal crash standard (FMVSS 213); price buys features and materials. Among the 49 with a list price, 31% of the priciest third have a load leg, versus 0% of the cheapest third; 75% of the priciest third have an anti-rebound bar, versus 6% of the cheapest third; 19% of the priciest third have rotation, versus 0% of the cheapest third; 63% of the priciest third have no added flame retardants, versus 25% of the cheapest third. The cheapest third lists under $230.
What's the cheapest car seat that rear-faces to 50 lb?
The Diono Radian 3R SafePlus at $259.99 list, rear-facing to 50 lb. 12 seats here reach 50 lb or more. See extended rear-facing seats.
Can you skip the infant seat and use a convertible from birth?
Yes, if the seat's minimum fits your baby: 14 of the 16 convertible and all-in-one seats we track list a minimum of 5 lb or less. Check the maker's minimum weight and height, the newborn insert and the harness height in the manual. Check the label and the maker's instructions, and ask your pediatrician about your child.
Which car seats are made without added flame retardants?
25 of the 52 we track say so, per each maker. The lowest list price is the Chicco KidFit ClearTex Plus at $109.99. They still meet the federal flammability standard for vehicle interiors (FMVSS 302).
How long do car seats last before they expire?
Between 6 and 10 years from the manufacture date, for the 39 that publish one. The longest is the Diono Radian 3R SafePlus at 10 years. The date of manufacture is on the seat's label; try the expiration calculator.
Do I need a new car seat after an accident?
After a crash, follow your seat's manual and NHTSA's guidance. Check the label and the maker's instructions, and ask your pediatrician about your child.
