So let’s get this best article started.

#1 Britax Advocate – Best Convertible Rear Facing Car Seat

Britax Advocate ClickTight Best Convertible Rear Facing Car SeatThis incident happened with my cousin. She was driving on the highway with three kids in the back. There was an accident ahead.

A long queue of cars was ahead of her. She noticed it too late. There were only a few things to do.

She slammed the brakes hard as she could and tried to avoid the parking cars in front of her. It’s extremely hard to come to a dead spot from 70-80 mph. She aimed at the dirt median.

She lost control and started rolling over. According to bystanders, her SUV rolled 5-6 times. It was a horrible accident. Everything that wasn’t nailed down became a lethal projectile. Their dog Coco was projected out of the car.

Finally, the car has stopped. The kids were all fine. They were shaken up, and not even Coco was injured.

The Britax Advocate won the Best Convertible Rear Facing Car Seat award.

It won because it has everything you’re child needs, plus it will keep them safe for a long time. Being a convertible means that you can install it rear or in forward facing mode.

The Advocate supports extended rear-facing. As you know, this provides the most safety to young kids. In the accident above, you can conclude that this car seat has protected the life of three kids.

Britax makes it so that means it’s the safest convertibles you can get. The installation is easy, no matter if you go with the latch system or the seat belt.

No matter what happens, this car seat will keep your loved ones safe.


It’s a fortress which provides both front-facing and rear-facing mode

According to a policeman parent, it’s absolutely the best

It’s easy to understand thanks to the well-assembled manual


It’s heavy once you have installed you won’t move from the car

ARB looks like an afterthought a bit flimsy

Runner up: Diono Radian 3RXT

Diono Radian 3RXT All-in-One Convertible Car SeatThis incident happened with a friend of mine. They were in a typical shopping run. The father was driving, and the boy was in the back.

Everything usually went until another driver ran the red light. The collision was unavoidable. They got hit from the side. The driver’s side exactly where the little boy was sitting.

The crash was loud as metal twisted under the huge pressure. The glass cracked and shattered.

The front side of their van was destroyed. The airbags did a great job of protecting the father. The little boy was by a miracle wasn’t hurt in the accident. He was scared. He had not even a scratch on him.

The Diono  Radian proved itself in a real crash. The little boy was safe and sound.

As a matter of fact, the Diono Radian it’s even a bit better than the Advocate. For example, you can do rear-facing up to 45 pounds, and it has a booster mode where the upper limit is set to 120 pounds.

It has a convertible part and a booster mode as well. It has fallen short because the installation is not that easy. I’m a stickler for manuals, and I’ve found it difficult to follow the instructions. Plus, they have over-engineered everything. You feel that you have to have a doctorate or a science degree just to attempt the install.

The second issue was that this is a huge car seat. If you want to do extend rear-facing, then you will have to mount it in the center, or there will be an unhappy front row.

The Diono was very close, but the drawbacks were too much.


Finally, a car seat where the baby isn’t slouching or sliding down

It’s lightweight and easy to move around

It’s soft and padded plus it comes with side impact protection


The gray fabric is not that stain friendly

You can’t remove the fabric the only solution is spot cleaning

#2 Chicco NextFit – Best Rear Facing Toddler Car Seat

Chicco NextFit Zip Convertible Car SeatThis incident happened with my brother. He went out with his son for a quick shopping run. He parked regularly and left his son in the car because he was absorbed in the game he was playing.

It didn’t take a minute when he heard a loud crash. He had a bad feeling. I dropped everything and ran out to see what happened. He couldn’t believe his eyes. His car got T-boned.

To make things worse, the crash happened on the side where his son was sitting. He ran as fast as he could. Ripped open the car to find his son playing with the stuffed animals as if nothing has happened.

The little boy started crying when he saw his dad’s panic. He was fine. He didn’t get hurt.

Chicco NextFit won the Best Rear Facing Toddler Car Seat award.

It’s not only built like a tank, but it provides a protective bubble around your little one. This convertible car seat is the best rear-facing one because it provides the most legroom. You can even do extended rear-facing until 40 pounds. According to Chicco, your kiddo will have 25% more legroom than other car seats.

Rear-facing is the safest way for a child to ride. This provides the best protection. Now the NextFit is not only safe as you have seen in the crash above, but it’s comfortable as well because it has a lot of legroom. Not to mention you can keep your little one in rear-facing mode for a long time.


By looking at your child you know, they are safe it’s like a protective shell

The frame is made out of reinforced solid steel, that’s safety in my book

It’s very comfortable on long rides


It’s a TANK very heavy and bulky

It’s hard to move from car to car once it fixed it stays there

Runner up: Cybex Sirona M

Cybex Sirona Convertible Rear Facing Car SeatThe Cybex Sirona M came in a close second in this category. It’s very similar to the NextFit. It’s the first smart convertible car seat on the market. It has three sensors to help make life easier.

The first sensor shows the temperature. It’s good to know if the car seat is too hot or cold, so you’re little one doesn’t get uncomfortable. Plus, it measures the temperature as times go by so you will know if your child is overheating.

The second smart feature is letting you know if you’re crafty child managed to undo the harness. On long trips, kids get bored easily. The third option is a reminder if you have forgotten your child in the car seat.

All the specs are similar to Chicco, plus you get the smart functionalities. Why did it lose? There are a few reasons. One of them would be that the sensors are not that accurate and tend to give frequent false positives. You can’t customize the sound alerts, and after a while, they will get on your nerves.

It’s a heavy car seat. It’s highly unlikely that you will be swapping it between cars. Lastly, the cover is not machine washable. This is a biggie since it caters to infants and toddlers who tend to have spills and accidents.

The Cybex Sirona M is a good car seat, but it wasn’t for me.


Kids get bored in car seats, so they tend to unbuckle luckily there’s a sensor for that

It comes with a bubble to get the seat leveled as easy as possible

Magnets keep the straps in place


The sensor isn’t that accurate there were false readings reported

Machine washing is not supported, hand wash only

#3 Clek Fllo – Best Extended Rear Facing Car Seat

Clek Fllo Convertible Car Seat

Extended Rear-facing up to 50 pounds

The Clek Fllo won the Best Extended Rear Facing Car Seat award.

Extended rear-facing provides the best protection for little ones. The more you can keep them facing the rear, the safer it is for them. It’s highly advised to keep your little one in this mode until the age of two. In some European countries, this limit is set to four.

With the Clek Fllo, you will be able to keep your little one in rear-facing mode until 50 pounds or around the four-year mark. This was the main reason why it has won the award. It’s one of the few car seats that allow this much rear-facing. Most of them tap out at 40 pounds.

Clek has something else up its sleeve. They were the first brand that passed the test without using any chemicals or flame retardants. So if you value chem-free materials, this is for you. Also, if you have a child with sensitive skin, then the Fllo is your safest option.

Though this doesn’t come cheap. It’s one of the safest and yet most expensive rear-facing car seats you can buy.

If you’re short on space, this car seat has a narrow profile, so three across will be doable.

It’s one of the safest car seats that allow the longest extended rear-facing, plus it has an eco-friendly cover. These are the reasons why it won.


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.

Runner up: Graco Extend2Fit

Graco Extend2Fit Convertible Car SeatExtended Rear-facing up to 50 pounds

This incident happened with some friends of ours. They were coming home from the grandparent’s house. Their young 11-month-old son was asleep in the back.

The trip was the usual one until a drunk driver smashed into them. The impact came from the front. The airbags instantly exploded and protected the parents. The engine didn’t stand a chance. It has twisted into an unrecognizable shape. The other driver, besides being drunk, was speeding.

The windshield shattered into a million sharp projectiles. It wasn’t over yet.

There was so much energy from the impact that their car did a 180 and flew across two lanes and stopped in the embankment.

The family got lucky; the parents got a few cuts and bruises. Their little one was safe and sound. He was scared and crying, but he was unhurt.

The Graco Extend2Fit was so close to taking the award. Besides being a safe car seat and protecting lives, it has a few flaws that cost the title.

This is not a light car seat. After you have installed it, you won’t be motivated to swap it between cars. There’s a flaw in the design. If you have a big hand, you won’t be able to reach the release button. Lastly, it’s extremely hard to reattach the cover after washing.

Since this car seat caters to infants and toddlers, you can imagine that you will have to clean up after accidents and spills. The Graco Extend2Fit is a good car seat with a few shortcomings.


It’s one of the easiest to install can be done in less than 5 minutes

There’s no manual rethreading of the straps ever

The fabric is easy to wash even after a vomiting incident


The release button is hidden, and if you have big hands it’s hard to reach

You need to watch videos to put the fabric back into place

Buyer’s Guide

I thought that it would be a great bonus if I share with you a buyer’s guide. As you know, I review a lot of car seats. So I had to create my system. This is what you’re getting for free.

Before we get there, here are two very important pieces of advice.

First of all, you need to find the best spot for the car seat. The safest place for your child is in the middle of the car because that’s where he’s most protected. I know that’s only doable for some. So here’s the second safest spot which is behind the driver.

The second piece of advice is to get the tightest install possible. There’s the rule of thumb of having the wiggle room less than an inch. Now some car seats are easy to install while others are notoriously difficult. All the car seats were tested by me personally and are OK to install.

If you want to be on the safe side, then you can reach out to a licensed professional.

Now I will share with you my buyer’s guide. If you like it, you can copy it.


Safety is top of my list. And for most parents, this is the main concern as well. Here’s the good news that all car seats on the market are safe. They have passed the government standards.

Now some brands go above and beyond when it comes to protection. The typical safety features include front and rear collisions. In recent years there has been a rise in side impacts. So a fair number of brands started, including side-impact protection or SIP. The more layers it can provide, the better it is. Typically there are between one to three layers.

Size Limits

This is the second item on my list. I want to share with you a little secret here. This is my favorite place in saving money without compromising on safety. The secret is that you get it for many years to come. These car seats are indeed more expensive, but they provide more mileage.

Of course, car seats are expensive, and they have short expiration dates. So this is the only way to save a bit of money.


Just recently read a troubling study which showed that 75% of car seats are installed poorly. This means that children aren’t protected by 100%.

This is so important to not just getting the right car seat but the one that’s the easiest to install. There’s some good news for you.

Lately, all major brands have evolved their installation process, so it has become effortless. From auto tightening to on push, I’ve seen them all.


This is the last item on my list. Since these convertibles cater to infants and toddlers, you can expect accidents. You need to know ahead of time the cleaning procedure.

Some seats only allow spot cleaning, while others are hard to remove or reattach. You need to be clear of these issues ahead of time.


We have reached the end of this best article. For each category, I’ve picked the best and the second-best. Just in case there’s something that you don’t like, you can choose another one.

By now you should know exactly which would be the best fit for you. And now it’s your turn. Get them soon because stocks are running low. The last time I’ve checked, there were some shortages.
