Best Car Seats of 2021

When buying a car seat, safety is the priority. In our search for car seats, we made sure our top picks meet federal compliance guidelines, and we looked into essentials like steel-reinforcement, seat size, ease of installation, lifespan, and weight range.

The car seat we found with all the best of those features and more is the Graco 4Ever DLX 4-in-1 Car Seat. With a 10-year lifespan and convertible positions, it’s the one-time purchase that can protect your kids from the first day home to the first day of school. Plus, it has a steel-reinforced frame and moves easily between cars.

Proper installation is essential to your child’s safety in a car seat. Thankfully, this seat is easy to install in any position. The Graco 4Ever can use your car’s LATCH system, adult seat belts, or both.

The Graco 4Ever DLX convertible car seat is pricey, but it’s a one-time payment for four stages of car seats. We were most impressed by its weight range (4–120 pounds) and its ability to shift between rear-facing, front-facing, high-backed booster, and backless booster seat positions.

Top that off with a 10-year lifespan, and this may be the only car seat your child needs until they fit an adult seat belt.

All of this is lined in machine washable jersey fabric to keep your little ones comfy during long rides, hot summers, and cold winters.

If you’re willing to drop a bit of cash on a high-quality car seat that will last for years, the Primo Viaggio is a safe and stylish choice.

It’s easy to install in your back seat too. The base secures by LATCH connectors or the adult seat belt in the back seat. Once the base is stable and level, just click the seat into the base and secure baby in. The easy-pull straps and five-point restraint system keeps your infant snug and secure for the whole ride.

It’s a great choice for an infant car seat, but with a max height of 30 inches and max weight of 30 pounds, your baby might outgrow it quickly. It has a six-year lifespan, so you can reuse it if you have a new baby in the family after your toddler outgrows the KeyFit.

While your child may outgrow its 35-pound weight limit in a couple of years, it’s reasonably priced for the life you get out of it.

It also has a tightness indicator on the strap and pockets on the side to tuck the buckles in while you settle baby in. All this comes with a steep price tag for a baby car seat, but it’s one small way to make parenting a little easier.

According to a 2016 report from the NHTSA, 49% of car seats and booster seats are used improperly.³ To us, that means the best car seat isn’t just safe, it’s easy to install. Seats with fool-proof installation will be less likely to malfunction or fail no matter how many other features they have.

Your child should also fit within the car seat’s weight and height requirements for the best installation and safety results.

You’ll also want to look at lifespan. Car seats typically expire in about six to ten years. This is long enough for your child to outgrow their car seat or grow into their adult seat belt in time to pass down to a sibling.

We recommend Graco 4Ever DLX as the best overall carseat because it is reliable from cradle to classroom.

Your children’s safety is important to us, so we worked hard to come to these results. We started by surveying over 50 parents about safety, convenience, price, and common features in car seats. This helped us align our priorities with those of many parents and caregivers.

Once we had all the data we needed, we compared top product lists with the features parents want most. The best car seats matched parents’ priorities and got high marks on professional reviews. From there, we compared features, read user reviews, and reviewed NHTSA standards for car seats.¹ Find out more about how we review in our full methodology.

In 2017, vehicle crashes involving children happened every 32 seconds.⁵ While safe driving can certainly help prevent events like these, a properly installed child safety seat can reduce fatal injuries by 71% for infants and 54% for toddlers in standard passenger cars.⁶

Reports from the National Highway Traffic Safety Administration (NHTSA) revealed which states had the most (and fewest) child fatalities in vehicle crashes between 2013 and 2017. In honor of Child Passenger Safety Week, we took a close look at how you can prevent these incidences with the right car seat.

According to the Fatality Analysis Reporting System database from the NHTSA, fatal car crashes involving children (ages 0 to 9) happened most (and least) frequently in these 10 states. The numbers shown are representative of every 100,000 children in each state. For example, for every 100,000 children in Wyoming, 6.44 were killed in a motor vehicle crash.

During our research, we examined a variety of sources including reports from the NHTSA from 2013 to 2017, state laws on child safety, and pediatric recommendations for the best safety practices for children up to 13 years old. While we didn’t find a direct correlation between lax state laws and traffic deaths, there were a few interesting findings worth mentioning.

• For every 100,000 children nationwide, 2.1 children died in a car crash between 2013 and 2017. Overall, there were 3,704 deaths. 
• In three years, Wyoming saw a 44% decrease in child traffic deaths. From 9.1 car crash deaths per 100,000 children in 2014 to 5.1 in 2017.
• There was a 213% increase in child car crash deaths in New Mexico between 2015 and 2017. From 3.2 car crash deaths per 100,000 children in 2015 to 10 in 2017. 
• Oklahoma’s fatality rate is nearly twice the national average at 4 deaths per 100,000. 
• In Arizona, only one child needs to be restrained in vehicles where there’s not enough room for restraints for every child. 
• Idaho allows children to ride out of their safety seat if held by an attendant for “nursing or to meet another immediate physiological need.”
• Fatal vehicle accidents involving children have decreased by 58% since 1975.7

No matter where you live, we recommend following the proven safety standards like those set by the American Academy of Pediatrics.

If you have a car seat in your vehicle, visit a Certified Child Passenger Safety Technician in your community to double-check that it’s properly installed. Find a car seat inspection station in your area or learn how to become a licensed car seat technician.

As your little ones grow up, they need a car seat that fits them correctly. There are convertible car seats that shift and change with your child’s growth stages, or you can purchase a new car seat for every phase. Either way, the car seat needs to be easy to install and hold your child securely. No matter what stage your child is at, the best car seat is a properly installed car seat. Follow this guide from the NHTSA to know when to transition to the next car seat for your child.

Infants to 3 years old: Babies and toddlers need to sit in a rear-facing seat until they reach the weight limit on the car seat. You can find convertible car seats that fit from infancy to 3 years old. Infant car seats have a shorter life span, fitting babies up to 12 months, while convertible models can fit older children up to 35 pounds (depending on the car seat model).

4 to 7 years old: Once your child reaches preschool age, they can typically sit in a forward-facing car seat. These seats generally fit kids from 40 to 60 pounds. When installing these seats, it’s especially important to fasten the top tether of your car seat to the vehicle’s seat. This can reduce head and neck injuries in case of a crash.

8 to 12 years old: This is typically when your child can transition from a forward-facing car seat to a booster seat. Depending on your child’s weight and height, they can use a belt-positioning booster or a backless booster seat. These seats are best for kids between 40 and 80 pounds and up to 4 feet 9 inches. See our recommendations for the best booster seats.

12 years and up: Until your kids are 13, the back seat is the best place for them to sit. Once your kiddos reach 4 feet 9 inches, they are generally big enough to use an adult seat belt in the back seat of your vehicle. This could be the back seat’s lap belt or lap and shoulder belt.

The SafeWise team evaluated car crash data from 2013 to 2017 from the National Highway Transportation Safety Administration to determine which states in the country had the highest and lowest numbers of child car crash fatalities per 100,000 children.
