Best Compact Convertible Car Seat

The little boy was sitting in the back… then somebody ran a red light… the impact happened on his side…

When an accident occurs, you lose all control.

The only thing to do is hope that all the safety features are there and give optimal protection.

What happens if you have a compact car?

Well, not everybody has the luxury of having a large truck or SUV, then how’s the best way to protect your little one?


Most car seats are designed for sedans or bigger cars, and few cater to smaller cars. I know all too well how much time it takes to find a regular car seat. Not to mention getting the right compact one will take you weeks, if not months.

This is why I’ve created the best compact convertible car seat article. By reading this alone, will save you a lot of time. If you stick with me for a bit, you will find out about the accident I’ve mentioned above. Not only that, but you will know which car seat was involved and how it has performed.

By reading this post until the end, you will find the perfect car seat that is safe and comfortable for all passengers. It doesn’t matter if you have a compact car or you’re looking for a compact seat; you will find the right fit.

Let’s get this best article started.

#1 Britax Boulevard ClickTight Convertible Seat – Best Compact Convertible Car Seat

Britax Boulevard ClickTight Best Compact Convertible Car SeatSize: 23” x 18.5” x 23.5”

The Britax Boulevard won the Best Compact Convertible Car Seat award.

As you have seen the dimensions, it will fit in your car. I have friends who are using it in a Prius. If it fits in the Prius, then it will definitely fit in your car.

The main reason why Britax Boulevard won was its size. Sure some convertibles are smaller by a half an inch, and they don’t offer the protection that you’re getting with Britax.

If you go with the convertible option, then you’re getting the best of both worlds. If you have a smaller child, you can mount the seat in rear-facing position. That’s the beauty of this compact seat that the first row will not be crowded. Usually, the forward facing mode doesn’t take up a lot of space.

Besides being compact, it’s the safest one to go with. It has a five-star safety rating. And I highly recommend getting the ARB because it’s a lifesaver. Since we’re talking about safety, it’s built like a tank. By having a steel frame, you get the most protection at the expense of weight.

Thanks to the ClickTight tech, the installation is a breeze.

Besides being a compact convertible, it gives the best protection, it’s easy to install, and it will last for many years to come. This is why it has won the award.


Opting for the ARB bar is a life changer

It’s a GAME CHANGER chair that lasts for ten years

#2 Clek Fllo Convertible Seat – Best Car Seat For Compact Car

Clek Fllo Best Car Seat For Compact Car

Size: 22” x 16.9” x 26”

The Clek Fllo won the Best Car Seat For Compact Car award.

At first glimpse, this car seat is bulky. And looks are deceiving. Check out the dimensions, and you’ll see what I mean.

The design team did an excellent job creating this car seat. It’s the most comfortable car seat I have ever tested. A good friend of mine had some issues with her little one. She didn’t want to travel by car. Every time they left, she was crying throughout the whole trip.

They were at the end of their wits. They tried a bunch of car seats, and nothing helped. Then they found the Clek Fllo. The little one liked it so much that she went quiet as soon as you placed her in.

This tells you something about the level of comfort. Another important thing you have to know about this seat is its fabric. Clek was the first one to pass all the tests without the use of polluting chemicals. Yes, you’ve read it right. They don’t use any harmful flame retardants. The secret is merino wool.

If you have a little one who has sensitive skin, this is the most ecofriendly car seat you can get. The truth is that the price is higher than other car seats.

Now you can’t beat their safety records the great fabric and that it’s an ideal seat for a compact car.


It looks good in the car, and it’s safe at the same time

It’s safe tests show that it has the least toxic chemicals and fire retardants

It’s the narrowest car seat you can buy. Two of these in the backseat, and there’s still room in the middle for an adult.


The resistive stain fabric is a good idea until a peeing accident. It fills all the hidden crevices so it will smell.

It’s hard to fly with this car seat. TSA agents warn against it.

#3 Diono Radian 3RXT Convertible Seat – Best Compact Car Seat

Diono Radian 3RXT All-in-One Best Compact Car SeatSize: 16.14” x 16.93” x 28.35”

It was like any other shopping trip. The little one was riding quietly in the back while dad was doing the driving. Everything changed in a split second.

While they were crossing an intersection, another driver ran the red light. The crash was unavoidable. Their car got hit from the driver’s side, the same side where the child was sitting.

The impact was loud. Metal screeched as it bent to the force of the impact. Their van’s front got destroyed in a blink of an eye.

The Diono Radian 3RXT did its job. They got lucky nobody got hurt. The little boy was safe in his car seat.

The Diono Radian 3RXT Convertible Seat won the Best Compact Car Seat award.

It’s a tall car seat other than that it’s a great one for a compact car. It has a narrow profile, so you will be able to do 3 across with ease with this car seat. There’s enough room for the front row even when you install it in rear-facing mode. That’s what counts. In front-facing mode, most seats don’t take up a lot of space.

We have to hand to Diono. They make one of the most beautiful car seats on the market. There’s a huge selection of vibrant colors to choose from. It’s built like a tank. The steel frame provides the best protection.

If you have a compact car, this Diono Radian 3RXT car seat is the best option for you.

#4 Graco SlimFit Convertible Seat – Best Convertible Car Seat For Compact Car

Graco SlimFit 3 in 1 Best Convertible Car Seat For Compact CarSize: 26.81” x 19.88” x 22.36”

Graco SlimFit Convertible Seat won the Best Convertible Car Seat For Compact Car award.

If you have a compact car, it’s extremely hard to put in or tighten those bulky car seats. The Graco brand thought about you. As their name suggests, the SlimFit was made for compact cars.

It’s not only small in size, but it has space-saving in it. According to Graco, you’re saving 10% in space. This means that 3 across is doable in a small car. You don’t have to get a bigger and more expensive car.

The main reason why convertibles are one of the best solutions is that you’re getting a lot of mileage for the money. These car seats aren’t outgrown that fast.

The Graco Slimfit gives you peace of mind that your child is safe and comfortable. Best of all, you don’t have to sacrifice the first row either. That’s the problem with bigger seats. You will be able to install it, but getting the kids in and out of the seat will be a chore. Not to mention that the front row will have no room to spare.

Even in rear-facing mode, you will be able to enjoy comfort. As you know, Graco products are not over the top expensive and give you many years of use.

It has everything you need: safety, comfort, and sturdiness

Honorable Mention: Graco Nautilus Convertible Seat

Graco Nautilus SnugLock LX 3 in 1 Harness Booster Car SeatSize: 18” x 20” x 28”

The Graco Nautilus didn’t make it on the list because it’s not a convertible. It caters to kids from toddlers and up. Other than these two small issues, it’s a good addition to compact cars.

The good news is that besides being small in size this will be the last car seat you will ever have to buy. The upper weight limit is set to 120 pounds so that you will be getting a lot of mileage out of this car seat.

Did you know that the Nautilus is one of the highest-rated car seats according to Consumer Reports? They went heavy on side protection. The thing is that brands start to neglect protection for older kids. Not with the Nautilus, you get the best side impact protection for the head and the torso as well.

Space is essential in smaller cars, so if you have an older child, this car seat will be perfect. Now the most space is taken up by rear-facing car seats with the Nautilus you don’t have that issue. It’s front-facing only.

There’s a newer version of Nautilus Convertible Seat, which relies on SnugLock Tech. That small upgrade made the install effortless.

The only reason why this car seat didn’t make it in the top is that it’s not a convertible.


It’s super easy to install just listen to the “Click” sound

It’s top-rated on Consumer Reports

#5 Chicco Keyfit 30 – Bonus Best Infant Car Seat For A Compact Car

Chicco KeyFit 30 Best Infant Car Seat For A Compact CarSize: 27.5″ x 24″ x 17″

I thought that it would be a good idea to throw a bonus car seat in the mix. Infant carriers aren’t that big like convertibles. And when every inch counts, it’s a good idea to know which carrier is the best for a compact car.

From all the carriers, the Chicco Keyfit 30 was the winner.

The only way to install these seats is in rear-facing mode. This is where the problems start with smaller cars. The Keyfit 30 is different. It’s one of the smallest yet safest infant car seats you can get.

According to Consumer Reports, it’s the highest-rated infant carrier on their site.

With babies, you have days and days. I like to call the Keyfit 30 as the instant tranquilizer. Whenever my baby had a bad day, I would place her in and rock her a bit. She quiets down so fast. It’s one of the most comfortable car seats you can get.

The installation is a breeze. You can use the base or without it. Once the base is in, all you have to do is click the carrier part in.

Now you know which the best infant carrier for compact cars is. Best of all, you’re not sacrificing safety.

Buyer’s Guide

That was a hell of a list. As a bonus, I want to give you a buyer’s guide. I’ve compiled this for myself since I’m reviewing so many car seats. I wanted to have my system so I can stay consistent.

This little guide will help you instantly how to look at car seats. If you see something that you don’t like, you will be able to eliminate it, thus saving your time.

Before we get to the actual system, there are two important pieces of advice you should keep.

The first one is related to how you position the car seat. As you know, the safest place is in the middle of the car. The truth is that only a handful of people would be able to use that. So here’s the second safest place which is right behind the driver.

My second piece of advice is related to the installation. The biggest problem nowadays is that most car seats are poorly installed. If the mounting isn’t correct, then the car seat won’t provide the best protection possible. So you have to make it tight. Remember the golden rule that the wiggle room should be less than an inch.

If you want to be absolutely sure, then you can always reach out to a licensed professional.

I have a quick checklist on which I go through when I check out a car seat. If you like, you can put it to good use.


Safety is top of my list. This is the reason why parents are looking for car seats in the first place. Now let me put your mind at ease. All car seats on the market are safe. If there would be issued, then they would be immediately recalled.

Most car seats are tested for front and rear collisions. Some brands did more than the bare minimum. If you see the sign SIP, it means that it has side impact protection. This is an all too common crash. Now your child will be protected from that as well.

This came to me as a surprise, but only a handful of car seats offer rollover protection. As you know, these are the deadliest crashes. I know of a few car seats that have been tested in real rollover crashes. The car was destroyed, but the kids were safe.

Size Limits

This is very important to know ahead of time. By choosing the right car seat, you will be able to save money in the long run.

Here’s the secret of saving money without compromising on safety. You have to get it for a longer time. It’s a good idea to consider the all in one car seat solution because those car seats are lifers. You buy it once, and you use it until your child doesn’t need it anymore.

Another thing to check here is if it offers extended rear-facing mode. As you know, this seating provides the most protection for kids. It’s recommended to keep kids rear-facing until their second birthday.

In some countries, 4 years is the norm.


The installation is the bane of the existence of car seats. Some are so complicated to install, while others are a breeze. On their defense, there were some significant improvements.

Every brand has made efforts to remove the amount of force needed for the install. If car seats are easier to install, then there will be less poorly installed car seats on the road.

It’s always a good idea to check out the manual for the install. If all else fails, you can go on YouTube and find a video there.

I’ve just noticed that Amazon has a service that gets your seat installed for a fee.


It’s crucial to get the right fabric. I mean, that will get the most wear and tear. Kids will have accidents and spills, and you have to know how easy it is to remove and wash.

Besides the Clek products, all car seats are washing machine friendly. With the Clek, you can do spot cleaning.


We have reached the end of this best article. By now you should know which car seat is the best fit for you. No matter the size of your car, there’s the right car seat above. Get the one that works the best.
