Best Car Seats: Infant, Convertible and All-in-One Picks
A car seat is the one piece of baby gear you can't leave the hospital without, and NHTSA's guidance covers car seats and boosters until your child fits a seat belt, somewhere between ages 8 and 12. There are three main kinds: infant seats that click in and out of a base, convertible seats that turn from rear-facing to forward-facing, and all-in-one seats that end as boosters.
The National Highway Traffic Safety Administration (NHTSA) says car crashes are a leading cause of death for children ages 1 to 13, and that the right seat used correctly every time is what protects them. The five seats below run from $100 to $320.

Graco Extend2Fit 2-in-1 Convertible Car Seat
| Rear-facing | 4 to 50 lb (listing) |
|---|---|
| Forward-facing | 26.5 to 65 lb, harness |
| Max height | 49 in |
| Legroom panel | Up to 5 in, 4 positions |
| Seat weight | 19 lb |
| Model | 2216092 |
NHTSA's main advice for toddlers is to keep them rear-facing as long as the seat allows, and the Graco Extend2Fit is built for that. The listing rates it rear-facing from 4 to 50 pounds, then forward-facing with the harness from 26.5 to 65 pounds.
A four-position panel at the front pulls out to give up to 5 more inches of legroom, so a taller toddler can stay rear-facing. The harness and headrest move together, with no rethreading, and the seat weighs 19 pounds.
It's the most-reviewed car seat we found, with a 4.8 rating from about 57,300 reviews, and it was $239.99 from Amazon. It doesn't click into a stroller, so a newborn rides in it in the car only.
Good for
- Rear-facing to 50 lb, among the highest limits
- Huge review base, 4.8 rating
Watch Out for
- Stays in the car, no stroller click-in
- Bulky with the panel extended
#2 · Best infant seat
Graco SnugRide Lite LX Infant Car Seat
| Rear-facing | 4 to 30 lb, up to 32 in (listing) |
|---|---|
| Carrier weight | 7.2 lb |
| Base | 4 positions, level indicator |
| Harness | 5-point |
| Model | 2110186 |
An infant seat clicks out of a base that stays in the car, so you can carry a sleeping baby inside or onto a stroller. At 7.2 pounds on the listing, the Graco SnugRide Lite LX is the lightest carrier here.
The listing rates it rear-facing from 4 to 30 pounds and up to 32 inches. The base has four positions and a level indicator to help you get the angle right.
It was $139.97 from Amazon, with a 4.8 rating from about 7,700 reviews. Like every infant seat, it will be outgrown, usually in the first year or so, and then you'll need a convertible seat.
Good for
- Very light carrier at 7.2 lb
- Clicks out of the base for carrying
Watch Out for
- Outgrown at 30 lb or 32 in
- Needs a Graco-compatible stroller to click in
#3 · Easiest infant seat to install
Chicco KeyFit Infant Car Seat
| Rear-facing | 4 to 22 lb, up to 30 in (listing) |
|---|---|
| Base | 2 bubble levels, leveling foot |
| Lower anchors | SuperCinch tightener |
| Newborn insert | Yes |
| Seat weight | 9 lb |
The Chicco KeyFit is built around installation. Its base has two bubble levels and a spring-loaded foot to set the angle, and a SuperCinch tightener for the lower anchor straps. NHTSA warns that a seat that isn't installed correctly can put a child at risk, so features like these matter.
The listing rates it rear-facing from 4 to 22 pounds and up to 30 inches, with a newborn insert, foam lining for impact protection, a canopy and a washable pad. It clicks into Chicco strollers.
Its 22-pound limit is lower than the SnugRide's, so most babies outgrow it sooner. It was $209.99 from Amazon, with a 4.8 rating from about 900 reviews.
Good for
- Install aids for a correct fit
- Clicks into Chicco strollers
Watch Out for
- 22 lb limit, outgrown early
- Priced above the SnugRide
#4 · Best all-in-one
Graco 4Ever DLX 4-in-1 Car Seat
| Rear-facing | 4 to 40 lb (listing) |
|---|---|
| Forward-facing | 26.5 to 65 lb, harness |
| Boosters | High-back 40-100 lb, backless 40-120 lb |
| Headrest | 10 positions |
| Seat weight | 23 lb |
| Model | 2215486 |
The Graco 4Ever DLX tries to be the only seat you buy. The listing gives four stages: rear-facing from 4 to 40 pounds, forward-facing with the harness from 26.5 to 65 pounds, a high-back booster from 40 to 100 pounds and a backless booster from 40 to 120 pounds. Graco calls it 10 years of use.
The headrest has 10 positions and moves with the harness, and the seat has 6 recline positions to help with installation. It weighs 23 pounds, so it's not one to move between cars often.
It was $319.99 from Amazon, the most expensive pick, with a 4.8 rating from about 2,600 reviews. Its rear-facing limit, 40 pounds, is lower than the Extend2Fit's 50.
Good for
- From birth to the booster years
- No-rethread harness, 10 headrest heights
Watch Out for
- Heavy at 23 lb
- Lower rear-facing limit than the Extend2Fit

|---|---|
| Forward-facing | 30 to 65 lb |
| Headrest | 5 positions |
| Seat weight | 12 lb |
| Pad | Machine washable |
| Model | CC396HMA |
The Safety 1st Ellaris is a convertible seat for about $100. The listing rates it rear-facing from 5 to 40 pounds and forward-facing from 30 to 65 pounds.
It has a slim shape for smaller cars, a 5-position headrest, a seat pad that goes in the washer and dryer, and two cup holders. At 12 pounds, it's light enough to move between cars, and the listing says it is designed for airplane travel and meets the federal side impact standard.
It has the lowest rating here, 4.3 from about 1,700 reviews, and the listing describes hook-style lower anchor connectors rather than push-button ones. It was $99.99 from Amazon.
Good for
- About $100 for a convertible seat
- Light and slim, good for a second car
Watch Out for
- Lowest rating of the five
- Fewer install aids than the Graco and Chicco seats

Car Seat Safety: NHTSA's Rules by Age
NHTSA counts 325 children under 5 saved by car seats in one year. Its recommendations depend on your child's age and size:
- Under 1 year: always rear-facing. Infant seats only face the rear; convertible and all-in-one seats usually let a child ride rear-facing longer.
- 1 to 3 years: keep your child rear-facing as long as possible, until they reach the top height or weight limit of the seat. Then move to a forward-facing seat with a harness and tether.
- 4 to 7 years: forward-facing with the harness until the seat's top limit, then a booster seat in the back.
- 8 to 12 years: a booster until the seat belt fits: the lap belt across the upper thighs and the shoulder belt across the shoulder and chest, not the neck.
Not sure which stage your child is in? Our car seat stage finder applies NHTSA's rules to your child's age and your seat's limits.
NHTSA's installation tips: install the seat with either the lower anchors or the seat belt, never both, and lock the belt as your car's manual says. Always use the top tether with a forward-facing seat. Keep children in the back seat at least through age 12.
A seat that isn't installed correctly may not protect your child, and NHTSA notes that not every seat fits every car. Test the seat in your car if you can, and have it checked at a car seat inspection station; NHTSA lists them on its website.
After a Crash, and Secondhand Seats
NHTSA says to replace a car seat after a moderate or severe crash. A seat doesn't automatically need replacing after a minor crash, which NHTSA defines as one where all of these are true: the car could be driven away, the door nearest the seat wasn't damaged, no one was hurt, the air bags didn't go off and the seat shows no damage.
For a secondhand seat, NHTSA's checklist asks that it has never been in a moderate or severe crash, still has its label with the model and date of manufacture, has no recalls, has all its parts and comes with its instruction book.
Register your seat with the maker using the card in the box or the maker's website, so you hear about recalls. Our article on checking a car seat recall walks through NHTSA's lookup and registration.
How to Choose a Car Seat
Infant Seat or Convertible from Day One
Infant seats are often sold with a matching stroller as a travel system; our travel systems guide compares five.
An infant seat like the SnugRide or KeyFit clicks out of its base, so you can carry your baby or click the seat onto a stroller. A convertible seat like the Extend2Fit or Ellaris stays in the car but lasts for years. You can also start with an infant seat and move to a convertible seat when your baby outgrows it.
Prefer one brand? Our Graco car seats comparison lines up six Graco seats by NHTSA stage.
Rear-Facing Limits
Our convertible car seats guide goes deeper on seats that stay rear-facing longest.
Since NHTSA advises rear-facing as long as the seat allows, a higher rear-facing limit buys more time in the safest position. The Extend2Fit goes to 50 pounds, the 4Ever DLX and Ellaris to 40 pounds, and the infant seats to 30 or 22 pounds.
Your Car
Check the seat's size against your back seat, especially if you need to fit two seats or have a small car. The Ellaris is slim and light; the 4Ever DLX and Extend2Fit are large.
Ease of Installation
Level indicators, built-in tighteners and push-button anchor connectors make a correct install easier. The KeyFit has the most installation aids of these five.
Car Seat Questions
When Can My Child Face Forward?
NHTSA says to keep your child rear-facing until they reach the top height or weight limit for rear-facing on their seat. Check the label and manual for your seat's limits.
Do I Need the Base for an Infant Seat?
The base makes clicking in and out easy. Some infant seats also install with the seat belt alone; the KeyFit listing mentions a belt lock-off. Check your seat's manual.
Where Can I Get My Install Checked?
NHTSA lists car seat inspection stations on its website, where a technician can check your installation.
The Bottom Line
If you want one seat from birth, the Graco Extend2Fit keeps a child rear-facing to 50 pounds and has the most reviews. For a light seat you can carry, choose the Graco SnugRide Lite LX, or the Chicco KeyFit for the easiest install. The Graco 4Ever DLX lasts into the booster years, and the Safety 1st Ellaris is a good second-car seat for about $100. Whichever you choose, install it as the manual says and keep your child rear-facing as long as the seat allows.
