Best Convertible Car Seats for Tall Babies: My Top 10 List

Britax One4Life ClickTight All-in-One Car Seat - Best Pick
  • Brand: Britax
  • Weight Recommendation: From 5 to 120 pounds
  • Harness Type: 5-point harness
  • Type: Rear-facing, forward-facing; highback booster
  • Adjustable Headrest: Up to 15 positions

Britax One4Life ClickTight convertible car seat is the safest one on our list!

Among the many safety features it offers, this convertible car seat will allow for your baby to stay rear-facing until they are around 50 pounds!

That's right, this car seat is among the best extended rear use seats, and I am here to give you the full review!

For starters, the Britax ClickTight convertible car seat is not exactly the best budget-friendly car seat on our list, but it sure is an investment worth every penny! 

Moreover, with one of the largest weight limits, the car seat can last you for at least ten years of use!

It is a breeze to clean it! Let me tell you; I had my fair share of car seats to know an effortless clean when I see one!

If your kid is a messy eater, you will love this car seat! The cup holders, along with the seat padding, are suitable for machine wash so your kid can always have a clean environment to go back to.

The car seat has one obvious downside, and that is the weight.

The child's car seat is significantly heavier than the competitors on the market, but I would sacrifice heavyweight for guaranteed safety anytime!

Now, as for the safety features I mentioned, the Britax 4-in-1 car seat includes SafeCell technology that works as energy absorption, up to two layers of side impact protection, and a steel-reinforced frame!

Lastly, it includes up to 15 positions in the headrest and the adjustable harness that follows the growth of your baby.

Pros
  • Easy to install with the LATCH system
  • Allows for extended child rear-facing riding
  • Safety features
  • Durable
Cons
  • Heavy
  • No anti-rebound bar

Graco SlimFit 3 In 1 Car Seat - Runner Up
  • Brand: Graco
  • Weight Recommendation: 5-40 in rear-riding position; 22-65 in forward-facing; 40-100 in highback booster
  • Harness Type: 5-point harness
  • Type: rear-facing; forward-facing; highback booster
  • Adjustable Headrest: Up to 10 positions

The Graco SlimFit 3-in-1 is the next pick on our list! It has advanced features, does not cost much, and is a perfect investment if you have an infant!

Why? Well, because you can use this convertible seat from a young age as soon as your baby is five pounds heavy up to highback booster position!

All you need to do later on is purchase a backless booster, but I have a few affordable options already selected.

As for this convertible seat, it's great if you want to use the extended rear-facing mode, as your kiddo can ride in this position until they are at least three years old!

However, if you want an even more extended rear-facing riding, then check out the Diono Radian 3RXT, 4-in-1 Convertible Car Seat.

Moreover, the Graco car seat includes up to four recline positions and ten headrest positions, so it fits the growth of your baby easily!

Finally, as I gathered from the manufacturer, it's also long-lasting that this particular car seat lasts up to 10 years!

Along with being comfortable, the car seat is also safe for your child! It has gone through rigorous tests to pass all the rear, side, front, and rollover crashes.

Lastly, you should know that the convertible seat is not so slim and narrow so that it won't be a good fit in a smaller car model.

Pros
  • Affordable price
  • Includes two cup holders
  • Large weight limits
  • The car seat grows with your baby
  • Kids up to 9 years old can use it
Cons
  • Bulky
  • Not suitable for three car seat installations

Safety 1ˢᵗ Grow and Go All-in-One - Best Parent-Friendly Car Seat
  • Brand: Safety 1st
  • Weight Recommendation: 5-40 pounds rear-facing; 22-65 forward-facing; 40-100 highback booster
  • Harness Type: 5-point harness
  • Type: Rear-facing; forward-facing; highback booster
  • Adjustable Headrest: Yes, but the adjustability is limited

The Safety1st Grow and Go car seat is another excellent pick for those who don't want to spend too much!

Its affordable price range is not the only good thing about it!

As you probably know, Safety 1st is one of the best-rated brands on Amazon, but it's also a favorite of parents who enjoy practical car seat models.

For starters, let's discuss the name of this model.

The Grow and Go car seat allows for longer use of the rear-facing car seat, just as our best pick! It also accommodates older kiddies as soon as they are ready for the belt-positioning booster seat.

That being said, your kid will probably use this convertible car seat until the age of six! If this does not sound like a good investment, then I don't know what does!

One of the unique features is the QuickFit harness.

As your baby gets bigger, the harness grows along with them and allows for easy adjustability. There is no need to re-thread or re-install a new one; all is done with a quick and easy motion!

The design is not only kid-friendly but parent-friendly as well! With the help of the harness holders that keep the straps away, you will easily take your kiddos out of the car seat.

And, for an easy clean-up, the car seat model includes a machine-washable seat pad you can take off and clean anytime! Plus, even the cup holders are machine-washable friends and can be removed!

Pros
  • Affordable price
  • Side impact protection
  • Machine washable padding
  • Energy-absorbing foam
  • Adjustable positions
  • Parent-friendly
Cons
  • Not so many headrest positions

Chicco Fit4 4-in-1 Convertible Car Seat - Best 4-in-1 Convertible Car Seat For Tall Babies
  • Brand: Chicco
  • Weight Recommendation: infant 4-16 pounds; toddler 12-40 pounds; forward-facing seat 25-65 pounds; highback booster 40-100 pounds
  • Harness Type: 5-point-harness
  • Type: rear-facing; forward-facing; highback booster seat
  • Adjustable Headrest: Yes

If you need a convertible car seat you can use as soon as your baby leaves the hospital, then this is the one.

The Chicco Fit4 4-in-1 car seat includes an infant car seat insert that accommodates infants by offering proper head and neck support.

Quite frankly, Chicco makes the best-looking car seats on the market!

Even though they are mid-price range, they still manage to deliver luxurious designs. Such is the case with this car seat, it's available in three different color pallets, and each of them is better than the last one!

As Chicco always puts safety as a priority, there is no reason why this convertible car seat would be any different.

This is the perfect car seat with the reinforced steel frame and side-impact protection if you are looking for added safety during transport.

Oh, and I have to state the obvious! This four-in-one convertible car seat will be the only car seat you have to buy ever! The four uses follow the growth of your child until the use of a backless booster!

Although it's packed with premium features such as cupholders, ten different headrest positions, and easy installation, Chicco does have one flaw.

That is the size!

The convertible car seat is significantly bulky and heavier than most car seats on our list. Due to its size, it could be impossible to fit other seats in the car if you have multiple children.

Of course, the installation depends on the size of your ride as well.

Pros
  • Easy to install
  • Steel frame
  • Includes cup holders
  • Easy to adjust shoulder straps
Cons
  • Bulky

Evenflo EveryFit 4-in-1 Convertible Car Seat - Best For All Stages
  • Brand: Evenflo
  • Weight Recommendation: 4-120 pounds
  • Harness Type: 5-point harness
  • Type: Rear-facing seat, forward-facing seat, highback booster, backless booster
  • Adjustable Headrest: Yes

Our previous pick was perfect for parents who need a four-in-one convertible car seat suitable for infants as well! However, you would still have to purchase a backless booster with that one.

With the Evenflo EveryFit 4-in-1 convertible car seat for tall babies, you will not have any additional purchases!

It can be adjusted as an infant car seat and as a toddler car seat and will last up to 10 years of age! Trust me, years fly by, and you will be happy you made an intelligent purchase like this one!

To top off the good looks, breathable fabric, and easy installation, the Evenflo car seat is budget-friendly as well!

It's great that it follows your child's growth and stage as well. For instance, the seat can be reclined in three positions to support the child's head in the rear-facing position.

On the other hand, the design has a high backrest for later on when your toddler suddenly begins growing right before your eyes! You will appreciate this feature the most because the kid is ready to ride in another position as soon as you know it.

If you value easy installations as I do, you will love that LATCH system guides can make installation twice as quickly as the traditional way.

However, the Evenflo's frame is made out of robust plastic instead of steel, so if you value a different pick, the Chicco Fit4 4-in-1 Convertible Car Seat is a better choice.

Although the company claims that the plastic frame is just as sturdy as the steel one, I still like to have a backup option I know is safer.

Pros
  • Affordable price
  • Infant car seat insert
  • Great for a tall baby
  • Breathable and comfortable car seat
  • Includes cup holders
Cons
  • Plastic frame

Diono Radian 3RXT, 4-in-1 Convertible Car Seat - Best Toddler Car Seat
  • Brand: Diono
  • Weight Recommendation: From birth to 120 pounds
  • Harness Type: 5-point harness
  • Type: Rear-facing position, forward-facing position, backless booster seat
  • Adjustable Headrest: Yes

Next up, we have the well-known Diono Radian car seat.

This may just be the best car toddler seat for bigger ones as it has a high backrest that accommodates the growth of your little one quite well.

In addition, due to its narrow and slim design, this convertible car seat fits nicely in smaller vehicles.

This feature makes this slim car seat a hot topic among parents as it is challenging to find a proper one for a small car.

As most of them are rather bulky, Diono is a refreshment in the car seat industry. However, it's not all that lightweight as it weighs around 30 pounds.

Nonetheless, it allows for three in a row car seat installations and has a massive weight capacity!

As you can see, your kiddo can use up to 120 pounds. It also has extended use of the rear-facing seats as it accommodates 50 pounds.

Moreover, parents love the comfortability of the Radian 3RXT convertible car seat because it means nap time is always guaranteed during the ride! It gives you the option to enjoy the ride and less of a chance to deal with a cranky toddler.

Some of you may not know, but the Diono was once available in another model. This brings me to the following issue.

If you did try out the previous version, you would know that it had plus padding, whereas this one lacks. However, it's still comfortable for toddlers and babies, but it just makes maintenance difficult as it requires a spot clean.

Pros
  • Allows for three installations in the back seat
  • Extended rear-face riding
  • Slim design
Cons
  • Difficult to clean
  • Heavy

Baby Trend Trooper 3-in-1 Convertible Car Seat - Best Budget-Friendly Convertible Car Seat
  • Brand: Baby Trend
  • Weight Recommendation: 4-65 pounds
  • Harness Type: 5-point harness
  • Type: Rear-facing infant mode, rear-facing toddler mode; forward-facing position
  • Adjustable Headrest: No

The Baby Trend Tropper 3-in-1 is an excellent find if you have triplets! Why?

Because the slim and narrow design allows you to fit three in a row car seat in the back seat with no problem whatsoever!

The 3-in-1 convertible car seat is our budget-pick and a quality model for parents who want fuss-free installation for their growing baby.

Now, even though it is pretty slim in design, the car seat takes up quite the room when installed rear-faced and is fully reclined.

This is because the convertible car seat also features an infant car seat position, so it might not fit to use in smaller vehicles if you do have an infant.

The harness is another feature we need to talk about.

Many parents noticed that during the rear-faced installation, the buckles work just fine, and it's a breeze to tighten or lose them up. However, it's the forward-facing car seat that presents a problem.

By installing it in a forward-facing position, the 3-in-1 convertible car seat puts pressure on the car's seat belt feeding system, so it's challenging to buckle your kids in. Therefore, you might have trouble getting the kids in and out of the seat.

The unique feature I found with this Baby Trend car seat is the low-belt slots for low birthweight babies.

In addition, the rear-facing harness can be routed to fit even the tiniest passenger. Plus, the harness is lined with anti-slip material, so it does not get twisted.

Pros
  • Affordable price
  • Low belt slots in the rear-facing harness
  • Includes a cup holder
  • Slim design for multiple car seat installations in the back seat
Cons
  • Difficult to buckle in the baby in the forward-facing position

Clek Foonf Convertible Car Seat
  • Brand: Clek
  • Weight Recommendation: From 14 pounds to 65 pounds
  • Harness Type: 5-point harness
  • Type: rear-facing; forward-facing
  • Adjustable Headrest: Yes

The Clek Foonf convertible car seat is the most expensive on my list, but it's for a reason as well. It has multiple safety features as well as incredible comfortability your kids will love!

So let's check it out together.

Firstly, this car seat is built with an incredible metal substructure.

It features both outer and inner energy absorption foam that protects your kid during a car collision. In addition, it softens the blow as the car seat is built to take in the energy from the crash.

Plus, it features side impact protection and an adjustable headrest that follows the growth of your toddler.

When the convertible car seat is in rear-facing mode, the anti-rebound bar will add a few extra inches of space, and that's why it's the right car seat for tall babies.

As you saw, the car seat accommodates both rear-facing and forward-facing installations, but it can also be used for infants if you purchase the additional insert.

In addition, the Clek car seat includes the rigid LATCH system for an effortless installation, making it easy to take the seat off and on. But, here's the trick.

The biggest downside of the seat is the heavyweight, so although the installation won't make the process challenging, the weight sure will.

So, once you install it in your car, you better not take it out as it weighs a little less than 40 pounds!

Lastly, it's made from Green+Clean fabrics that protect the seat from developing bacteria, stains, or moisture. It's also free from halogenated flame retardants.

Pros
  • Easy to install
  • High-quality fabric
  • Energy-absorption layer
  • 9-year expiration date
  • Smooth recline positions
Cons
  • Way too heavy
  • Pricy

Peg Perego Convertible Kinetic - Best Car Seat With Extra Leg space
  • Brand: Peg Perego
  • Weight Recommendation: From 5 to 65 pounds
  • Harness Type: 5-point harness
  • Type: Rear-facing; forward-facing
  • Adjustable Headrest: Yes

The Peg Perego is another trendy brand in the car seat industry, and honestly, I could not imagine my review without them!

They are super comfortable, constructed with care, and just wait till you hear about special features for tall babies and toddlers!

This seat can be used in a rear-faced position, and with that, it accommodates up to 45 pounds. Admittedly, it's not precisely the best-extended use in rear-facing seats, but it's still something!

Plus, with the addition of the anti-rebound bar, your tall baby will fit perfectly fine in this car seat!

Besides adding the extra two inches of legroom, the bar works well in the safety department. By that, I mean that it minimizes forces as well as a rotation during a car collision.

Furthermore, the car seat can be adjusted in up to 10 different positions. And, you know what the best part is? Your baby can stay in the car seat while you change it!

How cool is that? It's especially great for mommas who often carpool alone and can't put the baby down for even a second.

If you had asked me what the unique part of the Peg Perego car seat is, I would have to say it's the kinetic pods!

They help put everything away from the baby in case of a car crash or a side collision. In addition, the car seat includes side impact protection as well as an energy absorption layer.

Lastly, the car seat includes a Merino wool layer that keeps the baby cozy in the wintertime and cools during summer days.

Pros
  • Allows for two extra inches of legroom space
  • Humidity regulator layer
  • Kinetic pods
  • Easy to use the latch system
Cons
  • None that we found

UPPAbaby Knox Convertible Car Seat - Best For New Parents
  • Brand: UPPAbaby
  • Weight Recommendation: 14 to 65 pounds
  • Harness Type: 5-point harness
  • Type: Rear-faced; forward-faced
  • Adjustable Headrest: Yes

Let's close off the list with another exciting and popular car seat - the Uppababy Knox!

It's a convertible car seat with quality materials, includes adjustable positions, is easy to install, and includes up to 10 years of lifespan!

Firstly, the Uppababy Knox car seat includes the SmartSecure technology that indicates how you should install the seat and whether you did a good job.

This is best for new parents; I would sure want one of these back in the day when I had to deal with my first car seat installation.

Next is the multi-directional tether that significantly reduces the car seat rotation in case of a crash. It's strongly recommended to use both rear-facing and forward-facing seats to minimize the potential injuries by 45%.

The Knox model also has a removable cup holder on the side so your baby can sip away while you focus on the road ahead. Also, because it's removable, it makes installing another car seat much more manageable!

It has a smooth bottom base, so it won't damage a vehicle if you rent a car.

Moreover, the 2-in-1 convertible car seat has storage pockets for those harnesses so they won't get in the way while you are putting down the baby.

A downside I found was the heavyweight. Installing the car seat won't be tricky, but the 30+ pound weight will give you a headache!

Also, it has a low weight starting limit, so it's not suitable for infants and newborns.

If you are searching for a convertible car seat with an infant car seat insert, my recommendation is the Evenflo EveryFit 4-in-1 Convertible Car Seat.

Pros
  • Energy-absorption base
  • Side impact pods
  • Merino wool design
Cons
  • Heavy
  • Not suitable for infants

FAQs

What kind of car seat is best for a tall baby?

best rear facing convertible car seat for tall child

The best kind of car seat for a tall baby is a convertible one!

As much as we love rear-facing car seats, babies tend to overgrow them pretty fast, and before you know it, you need another car seat that fits their weight limit.

Convertible seats can accommodate both babies and toddlers until they are ready for their first booster.

It's best to find those with adjustable headrests and high backrests, as well as a big weight limit and spacious seat design.


How do you know when baby has outgrown car seat?

As much as extender rear-facing is recommended as the safest transportation mode for babies, there are a few signs you might have missed that indicate that the baby has outgrown their car seat.

One of them is that the head reaches one or two inches higher than the top of the car seat, and the other is that they surpass the weight limit.


How long should a child be in a convertible car seat?

best convertible car seat for tall skinny babies

A child should be in a convertible car seat for as long as they meet the weight limit.

Usually, convertible car seats' weight limit ranges from 5 pounds to 65 pounds. After so, if your toddler meets the requirements for a harnessed or belt-positioning booster, he is ready for one!

Kids usually use convertible car seats from nine months until they are two years of age.


What is the weight limit for a convertible car seat?

The weight limit for a convertible car seat is generally between 22-65 pounds in forward-facing mode, while the rear-facing position is between 5-40 pounds.

Therefore, convertible car seats are fantastic in being an affordable investment for the long-term transport solution.

In addition, you can use them with your infant, as some of them include an infant insert and with your toddler until they can ride in a booster seat!


What kind of car seat should a 7 year old be in?

best convertible car seat for large babies

As 7-year olds are too small to be restrained with only a seat belt, they should use either a highback or a backless booster.
