Best Brand of Convertible Car Seat Overall: Britax
When shopping for a car seat, it's good to know what the best reviewed, most reliable, most trusted brands in car seats are. In this instance, there's a single definitive answer.
The best and safest brand of car seat, with superior testing and materials, recognized by safety experts all over the world, is Britax. Britax has been an industry leader for decades, doing much of the research in Europe and Australia that would become the foundation for the US LATCH car seat installation system.
Britax created the first convertible car seat sold in the US, and has always been at the forefront of safety, technology, and standardization worldwide.
Britax car seats are recognized year after year, not just by parents and family organizations, but by the National Highway Traffic Safety Association, the Insurance Institute for Highway Safety, Consumer Reports, and the Juvenile Product Manufacturer's Association.

Britax Convertible Car Seats: Benefits & Features of Top Models
The Britax Advocate is the highest-rated convertible car seat for safety and ease of use, recognized by industry experts all over the world. It tops all the lists and reviews of the best, safest convertible car seats.
Britax Advocate features:
The durable steel construction and 10-year lifespan of the Britax Advocate makes it easy to use with a smaller child when the older one outgrows it, increasing the value of the purchase.
At 30 pounds, the Advocate is not easily portable, and even with simple installation, not designed to be moved from vehicle to vehicle. But it is an incredibly sturdy, safe, and protective convertible car seat to see your child through their toddler years.
The Britax Marathon is very similar to the Advocate. The main difference between the two models is that instead of 3 layers of side impact protection, the Marathon has 1 layer. This allows the car seat to have a slimmer footprint, making it easier to install 3 across the rear seat of a car, or to fit into an airplane seat or other slimmer space.
Britax Marathon features:
The Marathon has all the famous Britax features and advantages, but is a couple pounds lighter, and narrower overall. If the Britax Advocate is too big for your vehicle, the Marathon is a slightly scaled-down version that may be a better fit for your needs.
Finally, the Britax Boulevard sits directly between the Advocate and the Marathon. With 2 layers of side impact protection, it has the slimmer footprint of the Marathon, with some of the advanced protection of the Advocate.
Britax Boulevard features:
The Britax Boulevard is an excellent choice to save a little bit of money and gain some space over the Advocate, while still transporting your child the safest way possible. It's just a half pound lighter than the Advocate, so it's still a heavy car seat, but is a good compromise between the Advocate and the Marathon.
While Britax is the universally acknowledged best brand of car seat, they may not be the best choice for your specific needs.
There are two other things to consider when looking for the best convertible car seat: the best car seat for your needs (vehicle, lifestyle, and budget), and the best car seat for your child (if your child is unusually tall or heavy).
There are excellent car seats that are not Britax brand, that offer advanced safety, convenience, or features that might be right for you. Let's take a look at some of the other options in convertible car seats.
Best Convertible Car Seats for Different Needs
Best Convertible Car Seat for Small Cars
When you have a small car, the overall size, ease of access, and ease of installation for a convertible car seat matter even more. When you have less room to move yourself and your child in the back seat, you need a compact car seat, that is still roomy enough to be comfortable for your growing child.
The most compact car seats have a streamlined exterior, without protruding arm rests or features that interfere with other seats. The smallest child car seats are sized to fit 3 across the rear seat bench of a small car to securely transport up to three children in even very small cars.
Here are some of the safest convertible car seats for small cars:

Safety 1st is another excellent brand in child products. Originators of the famous “baby on board” vehicle signs, Safety 1st has its origins in child safety products. The attention to safety and protection that has made the company famous for over 30 years has only been enhanced in recent years as they have expanded into offering car seats.
The Safety 1st Guide 65 is one of the most popular compact convertible car seats on the market. With the cupholder removed, it's just 18 inches across, but still provides lots of comfort for a growing child. The ability to fit 3 of these car seats in the rear of a small vehicle, and the ability to convert it to a front-facing car seat, are both helpful features for a growing family.
Safety 1st Guide 65 Features:
The Safety 1st Guide 65 is a great car seat, and can accommodate larger children even with a compact-size car. However, some cars have an easier rear-facing installation of the Guide 65 than others.
If possible, read reviews or ask questions of those who have the same model of car as yours to ensure that it can be installed in the rear-facing position easily and safely.
Chicco was founded in Italy, and remains committed to the values of innovation, design, and quality that have defined the brand since 1958. Chicco holds a number of patents on their family-friendly products and innovations, and is always striving to advance safety, comfort, performance, and aesthetics.
The Chicco NextFit is an extremely popular convertible car seat. It is just slightly too wide to do 3 across in the most compact vehicles, but it can do 3-across in mid- and standard-sized vehicles. The NextFit boasts simple installation and advanced features for extra safety and convenience.
The Chicco NextFit has:
The very secure installation and harnessing system of the NextFit are one of the reasons it gets such praise from parents and experts alike, year after year.
With the NextFit, you are always sure that the seat is correctly installed for your vehicle, and that your child is securely harnessed in place. The 5-point harness tightens with a single pull for the simplest operation of any compact convertible car seat.
Maxi-Cosi is part of the Dorel Juvenile family of brands, that also includes Safety 1st. The Maxi-Cosi Pria 70 is designed to protect your child with maximum comfort. The self-wicking fabric stays dry, comfortable, and odor-free.
And the Pria 70 is designed so that you can remove the cover and the seat pad for machine washing and drying without un-installing the car seat, saving time and effort in keeping the car seat clean.
The Maxi-Cosi Pria 70 features:
Earlier models of the Maxi-Cosi Pria 70 had an optional (at additional cost) “Tiny Fit System” for children below 9 pounds, but the tiny fit system has been discontinued, so the Pria 70 isn't suitable for very small children.
However, the superior child comfort and ease of cleaning of this car seat have made it extremely popular, and it's rated for children up to 70 pounds, making it one of the most robust car seats designed for small cars.
Best Convertible Car Seat for Travel
Frequent travelers need more than just a convertible car seat that is FAA rated. They need a car seat that is lightweight and portable, easy to travel with in busy airports and long lines at security. It also needs to be easy to install and remove, so that it's a breeze to use a borrowed car, rental car, or any other vehicle when you're on the road.
Finally, it needs to be both comfortable and comforting for children who will spend protracted periods of time in the seat. And it needs to do all that without sacrificing safety standards. Frequent travelers have greater needs and high expectations for convertible car seats.
Some things to keep in mind for airline travel with a car seat:
Buying a seat on the flight
In order to use a car seat or airline child safety harness, you will need to purchase a seat on the flight for your child. Generally speaking, small children can fly for free (or for a steep discount) assuming that they will ride on their parent's lap during the flight, so purchasing a seat for your child is an additional expense.
However, if the flight isn't full, you may be allowed to use an extra seat for your car seat and your child, and it doesn't hurt to check in early for your flight and ask.
Calming your child
Some parents find that flying with their children is easier and less stressful when they purchase a seat and use a car seat, because the child is more accustomed to spending longer periods time secured in their car seat.
When a child is riding in a parent's lap, they can be more wiggly and restless than they might otherwise be.
Car seat width
The FAA recommends that a car seat to be used on a plane not be wider than 16 inches. Even the smallest car seats often exceed 16 inches, so that can be a difficult criteria to meet.
Generally speaking, car seats wider than 18 inches can't fit into a standard airline seat without raising the arms, but the arms can be raised to fit a larger car seat.
You can look up the seat width dimensions on your flight before you travel, and check to see if your car seat will fit.
However, if your car seat is FAA approved for airline travel, and you have purchased a seat for your child, the airline is responsible for accommodating that seat in the same class of service, regardless of the width, so it's more important that the car seat be FAA certified than that it be less than 16 inches.
Restrictions
A child seat cannot be placed in oblique seats in first class, and cannot be placed in an exit row. Many airlines require that they be placed in a window seat in order to ensure exit access.
Generally speaking, placing a car seat in the rear-facing position doesn't allow surrounding passengers to recline their seats, which can sometimes cause problems with other passengers.
Extra time
Installing a car seat in an airplane and removing it takes additional time, potentially adding extra pressure when trying to make connecting flights. If you have a connection to make, communicate early and often with the flight crew so they can support you.
Let's look at some of the best convertible car seats for air travel, and note that the compact Combi Coccoro reviewed above is also an excellent choice for flying with your child. Here are some of the other top models.

Clek is an American brand that emerged from the automotive industry, and they bring driven, automotive thinking to the design and manufacture of convertible car seats. All their car seats are made in America, and most of their materials are sourced in America as well.
The Clek Fllo is extremely popular with travelers due to its small footprint and high quality construction. The “Infant Thingy” insert (available for separate purchase) makes the Fllo even more versatile, able to accommodate smaller children than the seat alone.
This convertible car seat features:
The Clek Fllo is an exceptionally safe convertible car seat, narrow enough to easily fit into an airplane. With the “Infant Thingy” accessory, it will protect your child for years.
However, all that steel construction makes this a heavier car seat than many travelers prefer; at 24 pounds, it's literally not to be taken lightly.
Britax is one of the premiere names in car seats, and a previous model, the Roundabout, was a favorite for long-distance travelers. The Essentials Allegiance has replaced the Roundabout, with the same compact footprint and travel-friendly features, including easy installation and removal.
The Essentials Allegiance includes:
At less than 20 pounds, this convertible car seat is easier to travel with than some heavier models, and simple installation saves time on the go, while offering the same protection as more robust car seats.
Diono is a Seattle-based company, specializing in design and innovation. The Radian line is the first steel-framed car seat capable of folding for travel. The Diono Radian RXT is the premiere of truly 3-in-1, 3-across convertible car seats. It has won numerous awards and is a favorite brand of both parents and experts.
The Diono Raidan RXT features:
The Diono Radian is truly designed to be the one car seat that will protect your child from infancy through their first decade and be the only car seat they will ever need. It can be used as a booster seat until your child reaches 5'7” or 120 pounds, while still being compact enough to fit 3 across in a mid-sized vehicle. It even folds flat for travel, although at a heavy 27.6 pounds it isn't exactly portable.
Diono Recall: You may have heard about a Diono car seat recall in late 2017. During internal testing, the company found that under certain conditions, for children over 65 pounds, their car seats made after 2014 may have posed the risk of a chest injury. Because 65 pounds is at the upper limit of the weight range for their car seats, no actual injuries have been reported due to this flaw, and the affected car seats do not need to be returned.
Owners of the affected car seats need to use a new chest clip and pad provided by the company at no cost. Despite the recall, Diono car seats are still safe and a very good choice for airline travel.
However, if you are buying a new Diono car seat, particularly if you are buying it online, check the date of manufacture to see if it was made between January 2014 and September 2017. If it was, contact Diono for the free upgrade kit.
For older children, weighing 22-44 pounds, with their own seat on the airplane, you may want to consider getting the CARES safety harness instead of traveling with a car seat.
This harness weighs just 1 pound, and is the FAA preferred and recommended method of securing a child that size in an airplane. It's a fast, lightweight, cost-effective alternative to transporting a convertible car seat when traveling by plane.
Best Affordable Convertible Car Seat
Some car seats can be very expensive, and it can be difficult to justify the expense if your child will quickly outgrow the seat, and you won't be using it for years into the future. But of course it's crucial to not let your car seat budget affect the safety of your child.
A convertible car seat is a great way to save money because you only have to buy one car seat instead of two, making the purchase last for longer, and potentially even passing it down to another child.
When looking for the best convertible car seat on a budget, there's no reason to compromise on safety.
Here are the safest convertible car seats under $100.

The Evenflo Tribute is as lightweight as the Tribute LX reviewed above, at just 9.1 pounds, and has a fast and easy installation. While it is convertible and can protect your child from rear-facing to front-facing position, it is small and children will outgrow it at a younger age than some larger and more robust convertible car seats.
The Evenflo Tribute Sport features:
The Evenflo Tribute Sport is a slightly less expensive alternative to the Tribute LX, while retaining the light weight, safety features, and convenience of the other model.
Considering that this car seat will last for 6 years or protect your child until they reach 40 pounds, it's an excellent affordable convertible car seat.
While we don't normally think of “car seat” when we think of Disney, this Disney-branded convertible car seat is both affordable and highly rated.
And it comes in a variety of adorable Disney-themed designs and patterns to make car time more fun.
The Disney APT convertible car seat has:
While this car seat is only rated for children up to 43” in height, and therefore won't last for years to come, it's adorable and affordable.
People love the Disney APT car seat, and it's highly rated by parents who love the style and low price of this cute car seat.
Cosco car seats are consistently ranked among the best affordable convertible car seats, and these simple, low-maintenance car seats are an excellent value.
Without additional padding or an insert, it is not suitable for small infants, but is sturdy enough to protect children all the way up to 50 pounds.
The Cosco Apt 50 features:
At just 11 pounds, this one is also highly portable and airplane-friendly. For a simple, basic convertible car seat at a reasonable price, the Cosco APT 50 is always a favorite.
Best Convertible Car Seats for Tall & Heavy Babies
While the car seats we've talked about so far are all excellent choices for your needs and your lifestyle, they may not be the best or most comfortable for your child. If your child is unusually tall or big, it may be more difficult finding a car seat that is comfortable for them.
The truth is, while convertible car seats, and car seat regulations, are made with height, weight, and age recommendations, not all children are the same height and weight at the same age.
Children should remain rear-facing until:
That 1 inch margin is crucial for safety. In fact, if your child is under 2 years old, or under 40 pounds, but too tall for the rear-facing position, it is better to get a new car seat that is tall enough for their needs, rather than turn the car seat forward-facing early.
Children should remain forward-facing until:
Then they should transition to a booster seat, and continue to use that until:
They should remain in the back seat until:
If you have a tall child and are concerned about how they will fit in a convertible car seat, it may not be enough to check the manufacturer's height limitations. It might be a good idea to take your child to a store and “try on” some different models, even if you intend to do more comparison shopping and make a final purchase online.
With that said, here are some options if you have a baby who is taller than usual...

The Evenflo Symphony LX is another good choice for a tall child, with the design and durability to protect them until they are big enough to use an adult lap belt.
The Symphony features:
Infant inserts and robust booster makes the Symphony LX truly the only convertible car seat you will need for your child as they grow, no matter how tall they get.
The Graco 4Ever has a unique adaptation in the booster mode, where the back can be adjusted to accommodate larger children. With a weight range of 4-120 pounds and a lifespan of 10 years, this is the most versatile of the all-in-one convertible car seats.
The Graco 4Ever has the following features:
The 10 position headrest and wide range of weight and height allowances make this 4-in-1 easy to adjust to your growing child and get the maximum use out of a single car seat. It's a durable, versatile convertible car seat for a tall child.
The truth is, as many as 5% of children in America are too heavy for standard car seats, and more than 10% are severely overweight. This puts parents in the difficult position of putting them in car seats that are uncomfortable for the child, or using the car seat in a way that could compromise safety.
Important: Note that if your child is heavy and your car seat is heavy, it is important to check your vehicle owner's manual when using the LATCH system.
The weight rating of your lower anchors is specific to your vehicle, and many vehicles have lower anchors that are not rated to exceed 65 pounds with the combined weight of the child AND the car seat.
Even if the seat itself is rated to hold heavier children, your anchor system may not be. If the combined weight of the child and the car seat exceeds the weight rating of your anchors, you may need to instead rely on tethers and your car's seat belt to correctly install and secure your car seat, and not rely on a traditional LATCH install.
Car seat manufacturers are adapting to the need to safely accommodate these children in larger car seats, but here are some of the best convertible car seats for heavy babies.

The slender footprint of the Fllo makes it easy to fit 3 across, but the more open design and higher weight ratings make this a good convertible car seat for a large child. The optional Infant Thingy accessory allows this car seat to be used for infants as small as 5 pounds and 19 inches.
The Clek Fllo features:
It may be surprising that one of our slimmest convertible car seats is also rated to hold children several pounds heavier than most of the competition, but the Clek Fllo delivers just that. It's a comfortable way to transport a heavy child without compromising safety.
The Graco Extend2Fit 3-in-1 is a great choice for a big and tall child, as it has high weight ratings and an extendable panel for additional leg room. It also has the versatility to protect children from 4-100 pounds, one of the broadest ranges on the market, even in a 3-in-1.
The Graco Extend2Fit includes:
The Extend2Fit is a good choice for a child who is both tall and heavy, as the high weight ratings and extendable foot panel provide additional leg room with sturdy protection.
This is an excellent, versatile car seat for children of all sizes.
The Safety 1st Grow and Go EX Air is designed to be the only car seat you'll ever need, with the range to fit children from 5-100 pounds in a single convertible.
The Grow and Go EX Air also has a special design to give an additional 7 inches of adult leg room in the front seat when the car seat is installed in rear-facing mode, making this car seat not only a good choice for babies who need extra room, but for adults as well.
The Grow and Go EX Air features:
The Safety 1st Grow and Go EX Air is also easy to clean, which is a welcome feature in a car seat you plan to use for a decade. This is a great choice for big and tall babies, and big and tall adults as well.
Buyer's Guide for Convertible Car Seats: Choosing the Best Car Seat for YOUR Needs
Purchasing a car seat for your child is one of the most important safety decisions you will make. Car accidents are a leading cause of death and injury in American children, and the proper use of a car seat can prevent injuries and save lives.
The Centers for Disease Control presents these amazing statistics:
Car seat use reduces the risk for death to infants (aged <1 year) by 71%; and to toddlers (aged 1–4 years) by 54% in passenger vehicles
Booster seat use reduces the risk for serious injury by 45% for children aged 4–8 years when compared with seat belt use alone
So let’s be clear:
Car seats save our little ones from a heck of a lot of injuries and fatalities.
But here’s the problem: there are not only thousands of different types and styles of car seats to choose from, each state has different requirements, and each family has different needs.
And to complicate things even more, there are constantly new recommendations and regulations.
For such an important decision, it's frustrating that it isn't made easier and more straightforward!
That’s why we’ve put together this comprehensive guide. In this guide, we break down everything you need to know before you choose a car seat, help you choose the right one for your needs, and give you all the information you need to keep your child safe in a car for years to come.
Child Care Safety Seats: The Basics
Laws & Regulations
The National Highway Traffic Safety Administration (NHTSA) has set forth guidelines and safety standards that all car seat manufacturers must meet, governing the crashworthiness, flammability, labeling, and anchoring of car seats.
Every state has laws that require children to be safely secured when traveling in a motor vehicle.
So it's not just a good idea; it's the law to always have your child in the appropriate car seat when they are traveling in a car.
However, the legal requirements for manufacturers change over time, and different states have different rules. Is there a better standard to follow? Are there guidelines that would apply no matter what state you are traveling in?
Recommendations
Car seat recommendations are based on your child's age, size, and weight.
Our best and most consistent recommendations come from the NHTSA, the Centers for Disease Control, and the American Academy of Pediatrics, who agree on the best ways to transport children safely in cars:
Generally speaking, if you abide by these principles, you will also be in compliance with your state and local laws, but of course you should always check your state's DMV to be sure. But following these basic recommendations will also ensure you are traveling safely if you travel out of state with your child.
As we can see, according to the laws and recommendations, a child needs to transition from an infant car seat, to a child car seat, to a car booster seat, over their first 10 years. Over time, these different seats can add up to a significant expense.
For that reason, many parents opt for a “convertible” or “3-in-1” car seat that will adapt to your child's changing needs over time. A convertible car seat can be attached in the rear-facing position, then turned to the front-facing position, then transitioned into a booster seat.
Types of Car Seats
There are different types of car seats for every stage of a baby's development, based on how they should travel in a car. Here are the different types:
These are designed for the smallest babies, to be installed in the back seat of a car, facing backward. These car seats are also often designed for multiple purposes, so that the seat can be removed from the car and used to carry the child. Some infant car seats have multiple parts for multiple needs.
Some models have a base that is permanently installed in the car, but the carrier itself can be snapped into the base for car transport, snapped off the base to carry the baby, or even snapped into a stroller.
Rear-Facing Car Seat
These are to be installed using an adult seat belt in the back seat, until they are at least 100 pounds and can withstand the impact of a front passenger airbag.
Forward-Facing Car Seat
When a child has outgrown a rear-facing seat, they can be placed in a forward-facing car seat until they are older and big enough to sit in a booster seat.
Booster seat
This is a car seat that elevates a child's body and shoulders so that a normal car seat belt properly fits across their lap and shoulders. Children should sit in a booster seat until they are tall enough to correctly wear a seat belt without the booster.
Convertible car seat
Generally speaking, a convertible car seat is designed to transition from rear-facing to front-facing when the child is old enough. These car seats are larger, to remain big enough for the child as they grow, and allow a single car seat to do the work of two.
3-in-1
A “3-in-1” convertible car seat transitions from rear-facing, to front-facing, to a booster seat. They are intended to be the only car seat a parent needs to buy.
4-in-1
There are now a few “4-in-1” car seats on the market. These convertible car seats often have two booster seat modes for an even better fit as the child grows.
Many parents prefer convertible car seats to save the time and expense of purchasing multiple car seats.
Is a Convertible Child Seat Right For You?
There are pros and cons for convertible car seats, which should be considered carefully.

DURABILITY | All car seats have an expiration date, because the plastics and other components degrade over time and can compromise safety. If you are buying a convertible car seat, make sure it is rated to last for 10-12 years so you can get all the possible use out of it. |

Pros
Cons
If you have multiple children, they may be spaced in a way that lets you reuse car seats for more than one child. For example, if you had an infant seat that was rated to last for 5 years, you could use it with your first child, then get a child car seat for that child and reuse the infant seat for a new baby.
By the time the baby was ready for a child seat, the older child may be ready to move to a booster, etc. Having multiple car seats with shorter lifetimes for multiple children could meant that each seat is newer and therefore more compliant with changing safety guidelines.
Ultimately, convertible car seats are the best way to protect a child of any age in the car, with the strength to offer the best protection, and the versatility to meet their changing needs over time.
However, due to changing technologies that may advance new methods and materials, and due to the changing regulatory environment, it seems unlikely that many convertible car seats will actually be compliant 10 years in the future.
Choosing a Convertible Car Seat
When buying a convertible car seat, there are still a number of other factors to consider. A convertible car seat should be evaluated carefully for:
Safety
Design, materials, installation, and use should all be highly rated for the safety of your child. It's the most important consideration.
Convenience
Particularly because you want a convertible car seat to last for up to a decade, it needs to be easy to clean and have the features that will make it work well for you, as well as for your child.
Comfort
Your child should be comfortable in the car seat at any age. It should meet the needs of their body and posture as it changes over time.
Fit
Let's face it, some car seats weren't designed to fit into small cars. Will your car seat work for your vehicle?
Lifestyle
If your family frequently travels, or rents or borrows vehicles, you will have different needs for a car seat than someone who intends to install it once and leave it for years.
Many people purchase car seats for children who aren't their own: grandparents, caregivers, and family members may all find it easier to have car seats installed in their own vehicles rather than frequently removing them and installing them.
Budget. While no one ever wants to jeopardize the safety of their child for financial reasons, the fact remains that many car seats are very expensive.
When you consider that you may need to replace it if the child grows out of it early, and will have to replace it if you are involved in a collision, however minor, cost becomes even more of a factor.
Safety vs. Convenience:
Do You Need to Compromise?
The car seats that have the highest safety ratings and crash test performance are generally made of steel and surrounded by some sort of foam. The foam absorbs and diffuses impact, while the steel forms a cage that protects the child.
These car seats, because of all that steel, tend to also be the biggest, the heaviest, and the most expensive.
But sometimes a giant, 30 pound car seat is simply impractical for your needs and lifestyle. The fact is that all car seats meet (and the ones we will review today generally exceed) federal crash test safety standards, and many of them achieve a smaller footprint and lighter weight by using advanced polymers, and often honeycomb or impact-crumple technologies that we are now using in cars themselves.
While big, heavy, steel car seats are undoubtedly the most crash-resistant in all the standard tests, you need not feel that you are compromising your child's safety by choosing something lighter, more compact, and less expensive.
The best car seats are safest, of course, but any car seat also needs to be the right model for your vehicle, your lifestyle, and the comfort of your child.
Installation: The LATCH System
LATCH stands for Lower Anchors and Tethers for Children. It's a system of installing car seats in vehicles, and has been required for all vehicles and all car seats manufactured since 2002. The LATCH system was an important milestone, because it created a standard in all vehicles and car seats for universal installation.
However, it doesn't mean that the LATCH system is the only, or even the best, system to secure a car seat. In the years since the LATCH standard was created, many car seat manufacturers have innovated better and easier systems to secure a car seat, using the vehicle's integrated anchors and tethers, or seat belts in different ways to install a car seat.
The LATCH system also has a notable limitation, in that every vehicle has a different weight rating for the lower anchors. These weight ratings refer to the combined weight of the car seat and of the child.
While most anchors are rated for 65 pounds or more, many car seats weigh as many as 30 pounds themselves. If you buy a 29 pound car seat rated to hold your child until they weigh 40 pounds, the combined weight may exceed the weight limit on the anchors. A NHTSA rule added in 2014 requires vehicle manufacturers to improve labeling regarding these weight restrictions.
If you are buying a car seat for an older car, pay special attention to the installation methods and weight restrictions specific to your vehicle, to make sure you are choosing a car seat that you will be able to use properly in your car.
Before You Buy a Convertible Car Seat
Here are a few more things to keep in mind before you buy your car seat.
Accidents
Never buy a used car seat, or one from a manufacturer you don't trust. If a car seat has been in even a minor collision in the past, it may have invisible structural damage that compromises its safety rating.
Only buy a convertible car seat from a source you know and trust.
Recalls
Convertible car seats are often recalled for various reasons. Register your car seat with the NHTSA as well as the manufacturer, so that you can be notified if there are any concerns or recalls with your model of car seat.
Installation
Installation is the most important factor in making sure your child is safe in the car. Follow the instructions carefully.
Many local police and fire departments will also personally inspect your car seat installation to make sure that it is correct and safe, so take advantage of those programs. The best car seat can't protect your child if it is not installed correctly.
After You Purchase a Convertible Car Seat
After you have your new car seat, there are three things you need to do:
Register it
Registering your car seat with the manufacturer and with the NHTSA not only secures your warranty should there be problems with the seat, but also means that you will be notified of any future recalls that may affect you. Recalls of car seats are frequent, and generally minor, but it's important that you know of any safety issues the moment they are discovered.
The NHTSA has a program where you send them your car seat registration information, and they share it with the manufacturer on your behalf.
That way you get rapid notification about car seat problems and recalls, whether the problem is discovered independently by the manufacturer, or discovered during NHTSA reviews. It's a great way to protect your child.
Install it
Unfortunately, as many as 85% of child car seats are not correctly installed. Poor installation compromises safety, however well-made the car seat itself is.
While every car seat comes with detailed installation instructions, and there are often videos online with installation instructions, and also installation guidelines issued by the DMV and the NHTSA, it's clear that we are still not doing a good job of installing car seats.
For that reason, the NHTSA and other organizations have certified installation technicians who will install your car seat for you, or check your installation to make sure it's correct.
These technicians will give you a one-on-one teaching experience, so that you always know how to check your car seat, and install it properly yourself if you have to change vehicles.
Check the NHTSA directory to have your car seat checked for correct installation.

Conclusion
Never let your child ride in a vehicle without being properly secured, even if it's for a short trip. Never let a caretaker or family member drive your child without the correct car seat.
If your child will be riding in a car seat provided by a family member or caretaker, check it carefully yourself to make sure it's the right size for your child and that it is correctly installed.
Growing up I was a carefree male going about life like there was no tomorrow. Naturally, I ‘grew’ up, settled down and started a family.
Going from an independent carefree male to a family man was somewhat of a U-turn and required a lot of learning. Luckily for me, my wife works in education and has always been the shining light always ahead of me on all factors kids related.
Initially, my wife didn’t have a driving license (luckily this has now changed and it does make life easier), and all things car related were my task. Child locks were the obvious starting point which lead me down a rabbit hole.
So far we have personally tested dozens of convertible car seats and have owned five despite neither of our kids having reached the age of 5! Simply put, a car seat can be great on paper, work great on trying out but can fail on you in real life.
This is why I have put together this website – to help inform and educate you!
Of course, as I mentioned above, at the end of the day your experience will be the best test so I’d love to hear your experiences and feedback in the comments.
To contact me personally, please do so through my contact page.
I look forward to hearing from you!

Hello Sam,
Washington State changed it’s laws last year on car/booster seats so you will need to make those changes on your website. Incidentally, you emailed me for my thoughts on your website, but when I emailed you back the email address you provided does not work.
Have a good day,
Jenifer
Sam Webster says
Thanks, Jenifer! Will look into the changes.
Regarding the email, I was having temporary trouble with my email account. It’s all working now!
