Breaking it down

Since I’m reviewing a bunch of car seats, I had to create a system. Without it, I would be all over the place. The table above is my system. Actually, it’s my cheat sheet when I’m checking out a new car seat. You can copy it if you like to.

So #1 on the list is safety. Whenever I want a new car, seat, safety is the top priority. Here’s my recommendation to get the most safety as you can afford.

Next comes the size limits. To get the most mileage out of the car seat, pick the one that gives you the most months or years of use.

Ah, installation it’s the most difficult part of these car seats. Some brands are notoriously hard to install correctly, and others are a breeze. We’ll see where this Britax seats land on this scale.

The next item on the list is fabric. Now, these car seats cater for younger kiddos, so there will be accidents. And as a parent, you have to clean up the mess.

Finally, I take a look at the secondary features. Maybe there’s something very good hidden there.

child car seat safety 1Safety is a top concern. Let me reveal the industry’s dirty little secret. Every car seat on the market is indeed safe. If there’s an issue, the recall is immediate. Also, all car seats have passed the minimum requirements.

The secret is here. Some brands have barely passed the minimum requirements. Which car seat would you like to protect your child? The one that barely passed or the one that went the extra mile?

Usually, I break down the part into two. These car seats are so similar that I don’t want to bore you with repeating myself. So I will cover this at the same time.

Both the Britax Emblem and the Allegiance have a steel frame. This will keep your little one safe and secure no matter what. They both have an impact-absorbing base.

As you know, during a collision, there’s a lot of energy traveling through the car. The seat absorbs it so it won’t reach your child.

Here’s the first difference between the two. The Britax Emblem has two side impact protection layers while the Britax Allegiance has only one. This is good to know if there’s a T-bone accident.

They both have a 5-point harness, which is the safest one on the market. Slowly it’s becoming the industry standard.

Size Limits

These car seats are expensive, so let me share with you a money-saving secret. Plan for the long run. If you like, you can buy 3-4 car seats during your child’s life. But if you can cut it down to two or even one you will be saving a lot of money. Plus, they have a convenient short expiration date.

Both the Britax Allegiance and the Britax Emblem cater to infants and young kids. They have two ways of use, which is the rear-facing mode and forward-facing mode. Here’s a hot tip. It’s highly recommended to keep your child in the rear-facing mode as long as possible, preferably until the age of two.

This mode gives the best protection in case of an accident.

The lower limit is set to 5 pounds. So if you like, you can take your newborn home from the hospital with any of these car seats. And the upper limit is set to 65 pounds or 49”.

Both car seats are in the same weight category around the 20-pound mark.


child car seat installation 6Here’s where the rubber meets the road. This is the most cumbersome part of a child’s car seat. You need to get it installed. Let’s see how hard the Britax is.

Are you surprised? It’s the same process. Are these clones? We will see it by the end.

I will be upfront with you. The seat belt option is a bit complicated than the latch option. For that, to work, you will need to remove the cover material, run the belt through the path, and you need to use the lock-off mechanism.

This is the old-school method. Man, I miss the Clicktight install that was a breeze.

Check out the manual, and if you have to go online and see the install videos.


Since the base is the same, the material behaves the same way. Since you have to remove partially the cover for the install, you get the hang of it. The removal process is quite easy.

Now here’s the kicker. You are allowed to only hand wash it. Ever since I got use to machine washing, it’s hard to look back. And of course, air drying is the preferred way to dry both covers.

Everything still is the same.

Bonuses and Features

Let’s see maybe over here in this section we can find some kind of meaningful difference.

First, of not, the Britax Allegiance or the Britax Emblem has a cup holder. After the toddler age, it would be beneficial so that they can put toys there.

Here’s a minor difference. The Britax Allegiance has 3 recline positions while the Britax Emblem only has two.

The headrest options are the same. Both of them offer ten ways to adjust.

Here’s some good news. There’s no more manual rethreading what so ever. Whenever you adjust the headrest, the harness is adjusted as well. This goes for both car seats.

It’s still the same. Where is the difference?

Britax Emblem vs Allegiance Verdict

This is frustrating. After investing all this time, there’s no meaningful difference.

What I can tell that the Britax Emblem Convertible Car Seat seems to be a newer version of the Britax Allegiance Convertible Car Seat. It has one more side impact protection layer, and that’s it.

If you compare the pictures, you can see that the Britax Emblem has a different headrest style, and that’s it.

If you want a meaningful difference, then I guess it’s the colors. The Britax Emblem has Fushion and Dash while the Britax Allegiance has Azul, Confetti, Luna, and Static. The price difference is minimal, as well. So might as well go with the newest version.

I feel disappointed with this comparison. I mean, the difference is one extra layer of side protection and colors.

We have reached the end of the Britax Emblem vs Allegiance Convertible Car Seat comparison. At least now you know what the difference is. You get the one that fits you the best. Get them soon because the stocks are running low.
