The Ultimate Car Seat Guide.

Whether you’re a first-time parent-to-be researching the best infant car seat to add to your baby registry or a seasoned mom shopping for the safest booster seat for your second grader, the world of car seats can feel overwhelming—and for good reason. There are a lot of technical terms to learn and digest. Knowing which seat to use when is confusing. And wading through the many car seats on the market to figure out which one is right for you can feel pretty daunting.

“Car seats are often one of the most intimidating items to research,” says Rebekah Kimminau, a Child Passenger Safety technician (CPST) and founder of The Baby Gear Consultant. “Even once you are a parent and have experience using car seats, they can continue to feel overwhelming to purchase and install,” she says.

What you’ll quickly realize is that car seats are going to be a part of your life for at least the next decade—so learning the ins and outs is important. “If you spend time researching anything, it should be car seat safety,” says Kimminau. Bookmark this guide as the first stop every time you need to choose a car seat. We’re walking you through everything you need to know: the different types of seats, from infant car seats all the way through boosters; how to know which seat to use when and when to make the switch; and our picks for the best car seat in each category.

As Babylist’s gear editor, I’ve personally tested and reviewed dozens of car seats. I’ve interviewed countless car seat experts, including Child Passenger Safety technicians (CPSTs), pediatricians and other safety experts, and sifted through data and feedback from thousands of parents through Babylist’s annual Best Baby Products survey of over 6,000 Babylist users. I also have over a decade of hands-on car seat experience—from infant car seats through booster seats—as a mom of two boys, ages 10 and two. I drew from these experiences to compile this best of list. I also researched and consulted the latest safety recommendations from both the National Highway Traffic Safety Administration (NHTSA) and the American Academy of Pediatrics (AAP).

Best Infant Car Seat

What it is

An infant car seat is a car seat made specifically for younger babies.

Extended rear-facing refers to keeping your child rear-facing in their car seat until they max out the seat’s rear-facing limits.

When you need one

Infant car seats can be used from birth until your baby reaches the seat’s height or weight maximum. For most seats, these top limits are around 30-35 inches for height or 30-35 pounds for weight—whichever your child hits first.

Chicco KeyFit 35 Infant Car Seat - Onyx

Babylist $229.99 Amazon $229.99 Walmart $229.99 Target $229.99

From ease of install and excellent safety features to its slim profile and extended rear-facing limits, I can’t say enough good things about the Chicco KeyFit 35. And it’s not just my top pick; it’s also a parent and car seat safety expert favorite. (The parents we spoke to highlighted how easy it was to install and that it was lighter than many other infant car seats they’ve tried. Kimminau raves about the “tried and true installation that’s one of the easiest on the market” and the extra safety features.) It’s a well-priced seat that includes both safety extras like an anti-rebound bar (to prevent extra movement in the event of a crash) and convenience features like a no-rethread harness (so you can adjust the straps without having to undo and reroute them) and a removable, washable seat cover.

Best Car Seat Stroller Combo

What it is

A car seat stroller combo, also called a travel system, is an infant car seat and a stroller that attach.

A travel system lets you stroll with your newborn before they can sit up on their own—and makes car-seat-to-stroller transfers (and back again) a lot easier.

When you need one

A travel system is designed to be used from birth. That’s because unless your stroller comes with a bassinet attachment or fully reclines and is approved for newborn use, it’s not suitable for your little one until they can sit up on their own—which usually happens around six months of age. Most infant car seats included in travel systems can be used for about a year (until your baby hits either the height or weight maximum), and most strollers can be used well through the toddler years.

Most car seat stroller combos offer value, but not all offer quality. This one from Chicco delivers on all fronts and is an excellent combination of price, features and performance. Also called a travel system, this car seat and stroller combo includes my top infant car seat pick (and popular parent favorite), Chicco’s KeyFit 35, alongside a stroller with many high-end features including foam-filled tires, a suspension system, a huge storage basket and a multi-position reclining seat. And while it’s not inexpensive, this travel system offers incredible value for the quality.

Best Convertible Car Seat

What it is

A convertible car seat is a car seat that can be used with children of various sizes and can change from a rear- to a forward-facing seat. Convertible car seats don’t have bases like infant seats; instead, they use your vehicle’s seat belt or LATCH system for installation.

Convertible car seats are designed to stay installed in your car, unlike infant car seats which are a lot more portable.

When you need one

You can use a convertible car seat from birth until the preschool years and beyond. Car seat safety experts recommend children remain in a convertible car seat until they outgrow the seat by either the height or weight restrictions, which vary depending on the particular seat.

Graco Extend2Fit 3-in-1 Car Seat - Stocklyn

Babylist $249.99 Amazon $249.00 Target $249.99

“The original Graco Extend2Fit is one of the most-loved budget-friendly seats. This 3-in-1 version takes all of the beloved features of the original and adds on even more,” shares Kimminau. Personally, I’m partial to any car seat that allows for extended rear-facing (the safest way for your little one to ride)—and this seat from Graco is designed with this safety feature specifically in mind. (Many parents also choose this seat for exactly this reason.) It fits well in almost any type of car, even smaller vehicles, and is affordable and easy to install. It also converts to a high-back booster for years of use.

You can buy convertible car seats from the Babylist Shop or head to our Best Convertible Car Seats guide for more best-of picks plus information on extended rear-facing, features to look for in a convertible seat and convertible car seat FAQs.

Best Rotating Car Seat

What it is

A rotating car seat is a type of convertible car seat that spins on its base either 180 or 360 degrees.

When you need one

Like convertible car seats, rotating car seats can be used from birth until your child reaches the maximum height or weight limits allowed by your particular seat. Most rotating seats will last you into the preschool years, and some even longer.

What else you need to know

This rotating car seat is easy to install, packed with safety features and can be used for 10 years. Kimminau praises the “high rear-facing limit of 50 pounds” and the “smooth rotating feature and no-rethread harness for easy adjusting as your child grows.” It scores major points in my book for price (below many other rotating car seats on the market) and the fact that you only need to install it once if you use the seatbelt installation method.

If you think a rotating car seat might be right for you, you can learn more about these innovative seats and see our full list of top picks in the Best Rotating Car Seats guide or buy a rotating car seat from the Babylist Shop.

Best All-in-One Car Seat

What it is

An all-in-one car seat is a convertible car seat that’s designed to work from infancy through the elementary school years. All-in-one seats transform from rear-facing seats to forward-facing ones and then ultimately to booster seats.

When you need one

You can use an all-in-one car seat from birth until your child reaches the top height or weight limits allowed by your particular seat. Most all-in-one car seats will last into the elementary school years.

My top convertible car seat pick, the Graco Extend2Fit 3-in-1 Car Seat, does function as an all-in-one seat, as it ultimately converts to a high-back booster. But for another top contender, check out the Britax One4Life. It’s one of the easiest car seats to install (a properly installed car seat = a safe car seat) thanks to Britax’s patented ClickTight technology. “Britax ClickTight car seats have been around for 10+ years and are known as some of the easiest-to-install on the market,” says Kimminau. It converts from a rear-facing infant seat to a forward-facing five-point harness seat and then eventually to a high-back belt-positioning booster.

Best Travel Car Seat

What it is

There’s no true definition or specific categorization of a “travel” car seat; instead, what defines a travel-friendly car seat is its features. Things like a lighter weight, compact design and ease of portability are all factors to consider when you’re shopping for this type of seat.

When you need one

Most parents will use their everyday infant car seat if they’re traveling with a younger baby. But once your little one outgrows their infant seat, you may want a travel-specific convertible car seat since many other convertibles are large and heavy. Most travel car seats have the same or slightly lower height and weight maximums as regular car seats and can be used with babies, toddlers and preschool-aged kids.

Best Car Seat for Travel

Cosco Scenera NEXT Convertible Car Seat - $59.98.

Cosco Scenera NEXT Convertible Car Seat

Walmart $59.98

“One of the lightest convertible car seats on the market” according to Kimminau, the Cosco Scenera has been my go-to travel car seat for over a decade. Weighing in at only 10 pounds, this convertible car seat is as travel-ready as it gets. It’s easy to sling over your shoulder while you’re walking through the airport or install in an airplane seat or a ride share. It’s no-frills and takes a little practice to get a secure install, but it’s slim, safe and extremely affordable. Just note that it does have lower weight and height limits, so it won’t last your child as long as most convertible car seats, explains Kimminau.

Best Booster Seats

What it is

A booster seat uses a vehicle’s seat belt as a restraint. Think of a booster as the step between a car seat and a seat belt; it elevates a child in a car’s seat, making adult seat belts fit better on little bodies.

Most kids aren’t mature enough for a booster until at least five years old.

When you need one

It’s time to move to a booster seat once your child maxes out the top limits of their forward-facing convertible car seat. “Lately it seems popular to encourage your child to move to the next stage quickly—but for car seats, it can be a grave mistake,” explains Kimminau. Before transitioning from a harnessed seat to a booster, there are some critical milestones your child should meet. “Most importantly, they need the maturity to sit correctly in their booster seat every car ride, for the entire duration of the ride. If, at any point, they are slouching or not sitting correctly, the seat belt will restrain them properly in the event of a crash.” You’ll also want to make sure your child meets the minimum height and weight requirements of the booster seat and has a proper seat belt fit. (Most kids aren’t mature enough to sit properly in a booster until at least five years old; most hit this milestone sometime between five and seven.)

What else you need to know

Best Booster Seat

Graco TurboBooster 2.0 LX Highback Booster Seat - $89.99.

Graco TurboBooster 2.0 LX Highback Booster Seat

Amazon $89.99

Budget-friendly, light and easy to install, this high-back booster fits a wide variety of children well and transitions to a backless booster for years of use. It also has LATCH straps to secure it to the seat, which “keeps your seat from sliding around the back seat when unoccupied or between uses,” says Kimminau. It’s the booster I come back to again and again even after trying more elaborate, more expensive models. The seat also has cupholders and height-adjustable armrests.

How We Chose the Best Car Seats

How to Choose a Car Seat

A car seat is a registry must-have if you’re looking to take anything from a road trip to a ride to the grocery store with your little one in tow. But choosing one is a big decision. Here’s what you need to know.

Choose the proper type of car seat for your child

There are three main types of car seats: infant car seats; convertible car seats (including rotating and all-in-one seats); and booster seats. Your child’s age, weight and height all factor in when determining which car seat you should choose.

Car Seats By Age

Should I get an infant car seat or a convertible car seat?

While many convertible car seats will work for your little one from birth, most parents decide to start with an infant car seat first. (Eighty percent of Babylist parents register for an infant seat.) But why?

Some parents choose to skip an infant car seat and use a convertible from day one. It’s usually because they’re planning on babywearing often, want to save money by skipping the infant seat or are looking to limit the number of baby products they purchase.

Learn about car seat safety

The safest car seat is the one that fits your child correctly (is the right size for your child’s age, weight and height), fits your vehicle and can be installed correctly by you every time.

You’ll also want to pay attention to some specific safety features when shopping for a car seat.

We don’t recommend buying a previously used car seat. Used car seats may be damaged and may not meet current safety regulations. If you do decide to buy used, buy from someone you trust so you know the seat’s history. Look up the seat’s expiration date and research if that particular car seat model has ever been recalled. And be sure to follow the manufacturer’s rules around how to clean it safely.

And car seat features, too

There isn’t one magic thing that makes one car seat easier to use than another; however, there are certain features to look for when choosing a car seat that can make aspects of both installation and use of your seat a little bit easier.

Consider car seat placement and fit

Not all car seats fit in all cars. Some bases are too large for certain vehicle seats, and some car seats are too long front-to-back to fit properly in certain vehicles. Here are a few things to consider.

Always consult your vehicle’s owner’s manual for any special instructions. And don’t hesitate to find a Child Passenger Safety technician (a CPST, a trained car seat expert) to check your work.

Once you choose a seat, install it properly

A safe car seat is one that’s installed properly every time. Keep these installation tips in mind.
