Breaking it down

What you’ve seen above is my cheat sheet. I’m reviewing a ton of car seats. So to be consistent, I had to set up a system, so I deliver the same results.

The first thing that I start with is safety. There’s no arguing that’s the most important aspect of any car seat.

Next on the list is the size limits. You have to know in advance how much mileage can you get out of these seats. As we all know, these car seats don’t come cheap. In our case, with the Britax Grow with you and the Britax Frontier Clicktight, most likely, these will be the last car seats you will ever buy.

Installation is the biggest nuisance when it comes to these car seats. Some brands are notorious for being hard to install. And others make it super easy. We will find out how these two Britax seats compare.

The last important item on my list is the material quality. Since both car seats cater to younger kids, you can expect spills and accidents, so you have to know how easy they are to remove and clean the fabric.

Finally, I look at the secondary features. Sometimes I manage to find some real gold nuggets there.

Let’s get this Britax Grow with You vs Frontier Clicktight comparison started. Just one more thing…

I have something special for you in the end. I have compiled a quick pros/cons list. The things I’ve found are quite interesting, to say the least.


child car seat safetyIt’s common knowledge that Britax seats are safe. They have won multiple high rankings on Consumer Reports. What I like about Britax is that they always try to push the envelope. The more protection you can get, the better for your child.

Britax Frontier Clicktight Booster Seat

This has happened with a friend of mine.

It started like any normal day. She was taking home her two daughters, ages five and seven, from ballet practice.

The light turned red, and she stopped. In a matter of seconds, there was a loud bang, and the car started moving again.

Their SUV just got rear-ended by another SUV. Later on, she found out the driver in the back has hit her car while going 50 mph. The trunk was squished, and the rear window exploded into a million shards.

The worst was yet to come.

The two stuck together SUV’s were heading towards another parked SUV. There was nothing to do. She could only brace for impact. Metal screeched and bent because of impact force. The airbags exploded.

The convoy finally stopped. The results were two SUV’s totaled and the third heavily damaged.

When my friend came about, she immediately checked on the kids. They were lucky. The Britax  Frontier Clicktight car seats did their job. The kids were safe and sound without a scratch or an injury. They walked away from the accident, shaken up.

This is what it means to have the best protection possible. The Britax Frontier has a steel frame that protected the kids. Plus, it has impact absorption properties, so the energy doesn’t travel up into the kiddos bodies.

The Britax  Frontier Clicktight comes with two layers of side protection, and your little one is safe, thanks to the 5-point harness.

Britax Grow with You Clicktight Car Seat

The Britax Grow with You is a new one on the market. I haven’t found any real crash test reports. So I can only judge it by its merits.

There’s only a tiny difference between the two car seats. The Britax Grow with You has a steel frame, so your child is safe no matter what. Plus, it has three layers of side protection. The more protection, the better it is.

The Britax  Grow with You has impact absorption thanks to the safety cell tech. This honeycomb design absorbs the impact energy, thus protecting your child from harm.

The 5-point harness is the safest one on the market. Slowly it’s becoming the industry standard.

Size Limits

As you probably experienced it, these car seats are expensive. This is my favorite way to save money without compromising on safety. Here’s the secret. All you have to do is the plan. For instance, if you buy either of these seats, you won’t have to buy a new one. It’s going to be the last car seat for them.

They are both made by Britax, so the characteristics are the same. I won’t bore you by repeating myself.

The Britax Grow with You is the latest version from Britax. There’s one big difference in this section. I will share it with you in a bit.

Both car seats have two modes the harness and booster options. The Frontier allows the harness mode up to 90 pounds, and the Britax Grow with You’s upper limit is set to 65 pounds.

This is the only difference. The upper limit for both is set to 120 pounds.

As for weight, it seems that the Britax Frontier Clicktight is heavier by one pound. It weighs 25 pounds while the Britax Grow with You only weighs 24 pounds.


child car seat installation 2This was the most hated part of car seats. Now it has become easy. All this came about when Britax released the ClickTight option.

For both car seats, it’s the same procedure. You remove the back fabric and pop the compartment open. You put the seat belt through the guide, and then you close the door. When you hear the click sound, you’re set.

This is so easy. Anybody can get it done on the first try.

If you have it installed correctly, then it will do its job in case of an accident.

The lower age limit for both car seats is two years old. As we know, toddlers tend to be messy. Not only that, but they will also surely spill something or have an accident. This is why it’s important to know in advance how easy it is to remove the fabric and how you can wash it.

Again for both seats, it’s the same procedure. With the installation, you will get used to the fabric removal. It’s easy.

Here’s a heads up. With the Britax Grow with You, only the Plus version is machine washable. With the Frontier, there’s only one version, and that’s machine washable.

The real difference

There’s not much difference between the two car seats. Let me share with you what matters the most.

When you look at those seats, you can tell that the Britax Grow with You Clicktight Car Seat is beefier than the Britax Frontier Clicktight. This comes from the extra level of side protection.

Now the other difference was that the Britax Frontier Clicktight has a higher upper limit for harness mode. While the Britax Grow with You only allows 65 pounds, the Britax Frontier Clicktight is set to 90 pounds.

Is this a good or a bad thing?

There’s an unconfirmed rumor that, according to some Consumer Report’s test, the Britax Frontier Clicktight Booster Seat didn’t do so well when the crash test dummy was higher than 65 pounds. This is the reason why they have dropped the upper limit.

It seems that Britax is slowly phasing out the Pinnacle, Pioneer, and Britax Frontier Clicktight Booster Seat.
