With the aptly named Graco 4Ever, you’ll only need to buy one car seat for your child—which is why it's the best convertible car seat on the market. This 4-in-1 seat does it all, starting as a rear-facing harness and adapting to every stage of your child’s growth. 

When used as a rear-facing harness, the Grace 4Ever can accommodate children between 4 and 40 pounds, and as long as their head is at least 1 inch below the handle. When you switch it to a forward-facing harness, your child should be between 22 and 65 pounds and 27 and 52 inches tall. Once they outgrow this stage, the car seat then transforms into a high-back booster seat, which is appropriate for children 30 to 100 pounds and 38 to 57 inches tall. Finally, it can be used as a backless booster with children up to 120 pounds and 57 inches tall. 

This versatile car seat also features a ten-position headrest, a five-point harness, a six-position recline, a steel-reinforced frame, and integrated cup holders. It comes with the LATCH system for easy installation.

Parents can’t say enough good things about the Nuna RAVA convertible car seat, and many are adamant that this high-end model is worth every penny. This car seat is recommended for children 5 to 50 pounds and 49 inches or less in rear-facing mode and little ones 25 to 65 pounds and 49 inches or less when forward-facing. That means you can keep your little one rear-facing for longer than most other seats, even if your baby hits their growth spurts early.

The Nuna RAVA has a five-point harness, ten-position reclining feature, and a ten-position headrest, as well as a two-position buckle. It’s aircraft-certified if you need to travel by plane, and there are both head and body inserts that you can remove depending on how much space your child needs. Reviewers call this model the “Rolls Royce of car seats,” writing that while it’s on the heavier side at 27 pounds, it’s incredibly sturdy and secure.

Best for Small Cars: Graco SlimFit 3-in-1 Convertible Car Seat

If you have a compact car, big, bulky car seats might not fit properly. In this case, you’ll want a model like the Graco SlimFit, which serves as a 3-in-1 car seat. This model measures 16.25 x 25.5 x 19.75 inches, and its rotating cup holders can be tucked away to take up less space in your back seat. 

This car seat will be a staple for your family, as it protects kids from 5 to 100 pounds. When it’s rear-facing, it’s great for babies 5 to 40 pounds. You can convert it to forward-facing when your child is 22 to 65 pounds and under 49 inches tall, and it can serve as a boost for children 30 to 100 pounds and 38 to 57 inches tall. It has four recline positions, as well as integrated harness storage, the InRight LATCH system, and rotating cup holders.

Best for Tall Kids: Diono Radian 3RXT Convertible Car Seat

The best convertible car seat for tall kids is the Diono Radian 3RXT, which has extended rear-facing abilities that let you keep your little ones rear-facing for longer, even if they’re growing like a bean sprout. It can be used as a rear-facing harness with children 5 to 45 pounds and up to 44 inches tall and as a forward-facing harness for kids 20 to 65 pounds and whose height is under 57 inches. The Diono Radian 3RXT can also serve as a booster seat for children 50 to 120 pounds. 

This car seat fits three across in most family-sized vehicles, and it has a 12-position headrest, memory foam seat, and extendable leg rests. There are five shoulder and three buckle positions, and it even folds up flat for easy travel. Reviewers say this convertible car seat is compact and user-friendly, but keep in mind that because it’s designed for tall kids, the seat itself is tall and might not fit well in smaller cars. 

Most Comfortable: Britax Marathon ClickTight Convertible Car Seat

You can keep your kids comfy on long rides (and short ones) with a car seat like the Britax Marathon. This popular convertible car seat works as both a rear- and forward-facing model, and it has a variety of features that ensure your kids are comfortable at every turn. It can hold children 5 to 40 pounds in rear-facing positions (their head should be at least an inch below the top of the head pad), and kids 20 to 65 pounds and under 49 inches can ride in it forward-facing. 

The Britax Marathon ClickTight excels in its adjustable features—it has a 14-position easy-adjust harness, seven recline positions, and two buckle positions to ensure a comfortable fit as your child grows. It’s lined with plush foam padding as well, and many reviewers say their children regularly fall asleep in this car seat.

How We Tested

Our reviewers spent 10 hours testing one of the top-rated convertible car seats available. To ensure the most complete feedback, they set it up in their cars and had their own children try it out for themselves. We asked our testers to consider the most important features when using this convertible car seat — from comfort to durability — and we've outlined the key points here so that you, too, know what to look for when shopping.

What to Look for in a Convertible Car Seat

Longevity: While convertible car seats are generally meant to last through several stages of your baby’s growth, some are more versatile than others. For example, there are models that work from a child’s infancy until they weigh about 120 pounds, while others have narrower weight ranges (like 20-65 pounds). Beyond height and weight limits, pay attention to adjustable features, like the number of harness positions, so that a seat is comfortable over time.

Ease of use: There are two main things to consider when it comes to a car seat’s ease of use: getting your child in and out of it and getting it in and out of your vehicle. Look at factors like its harness, the shape of its seat, and how it’s secured in your car. If you plan to use your car seat frequently, little time-saving features can add up to major headache relief over time.

Comfort: Some car seats are cushier with cup holders, lots of padding, and other features that make for a more comfortable ride. Of course, those extras usually increase the cost, so consider your budget as well as how often you’ll be using your car seat. If you’ll use it daily, spending more on a model with fancy features may be worth it.

One of our testers — who used this car seat with her 2-year-old son in her Toyota Avalon — said that strapping him in was “easier than other models we’ve tried.” She added, “He was very happy in this!” Other highlights were the seat’s attractive design and the fact you can use it in four different configurations as your child grows.

Our testers wished this seat had a foot extender (for taller children) and that the instructions were a little less technical: “I wish they had more basic-level stuff like when to use certain versions of the car seat at certain times,” said one reviewer.
