Britax G1.1 Frontier Harness-2-Booster with Clicktight – An In-depth Review

Parents have a lot of variables to consider when purchasing a car seat. Some car seats claim to be the most comfortable, or the best value, or even the safest. With so many options, how can you know where to start? The Britax G1.1 Frontier Clicktight Combination Harness-2-Booster Car Seat combines safety and comfort, but is at the high end when it comes to cost. What is Clicktight and is it worth the extra cost? Read about my experience and get my honest recommendation.

Key Features


  • Weight: 25-90 pounds as a harness seat, 40-120 pounds as a booster seat
  • Height: 30-58 inches as a harness seat, 45-62 inches as a booster seat

What is Clicktight?

Britax features what they call Clicktight on some of their car seat models. Clicktight is an installation system that makes it really simple to install the car seat each and every time. Any time I needed to reinstall my son’s infant seat in the car, I would nearly pull a muscle trying to get the installation straps tight enough. Instead of having to fight with the installation straps to tighten them correctly, the Clicktight feature tightens the strap for you. Simply put, it ensures proper installation each time and gives you some peace of mind.

I’m one of those people who likes to do everything myself, especially when it comes to my son’s safety. It gives me anxiety to think about someone else installing a car seat because I’m concerned they won’t do it right. With Clicktight, it’s so easy to install that I honestly trust anyone to do it correctly. When you click the car seat closed, it is so tight that you can’t even move the seat at all. The Clicktight feature has given me the confidence to know that the car seat is always installed correctly.

You can get the Britax G1.1 Frontier car seat without the Clicktight feature at a cheaper price. When I purchased my son’s car seat, I went back and forth on whether or not to pay extra for the Clicktight model, and eventually decided to pay the extra for it because I figured it was worth it for the peace of mind it would give me.

Super Safe

The Britax G1.1 Frontier model features a steel frame and energy-absorbing materials to reduce movement of the car seat and to limit impact forces in the event of a crash. This model also has 2 layers of side impact protection and an energy absorbing headrest to protect your child’s neck and head. I like that Britax has gone above and beyond the safety standards and are ahead of the game in terms of new safety technology.

Easy to adjust

The Britax G1.1 Frontier Harness-2-Booster model has 9 different harness positions which allows it to grow with your child. I’ve had car seats that are confusing or difficult to adjust, but the Frontier is really easy to switch between positions with a quick squeeze and lift.

Adding to the easy adjustability is a front adjust recline lever, which allows you to recline the seat to your child’s comfort. The fact that the lever is in the front makes it easier to recline when the car seat is already installed. I had a car seat that had this lever in the back and it was almost impossible to adjust it when the seat was installed in my little sedan.

I see this feature as a major plus. It’s one of those things that I wouldn’t have even thought of when looking for a car seat. I love that Britax considered this in the design of the Frontier.

Britax car seats also have easy to adjust 5 point harnesses, eliminating the frustration that comes with tightening and loosening the straps when getting your child in and out of their car seat.

Slim Design

The Britax Frontier with Clicktight features a slim design that allows it to fit more comfortably in compact sedans. This is especially helpful if you have more than one car seat in the back seat. Additionally, the sides on the Frontier are more open than other, bulkier, car seats. I know most kids like to have a clear view of the outside world, and they definitely will with this seat!

Long Lifespan

The Britax Frontier has a lifespan of 9 years. All car seats have an expiration, but most do not last this long. This further justifies the extra upfront cost in my opinion, because you will get plenty of use out of it. Because it is so adjustable and has such high weight and height limits, you can keep your child in it for longer, which is safest for them and is recommended by experts.

The Britax Frontier with Clicktight is one of the most expensive front-facing car seats on the market. As I mentioned before, you can buy this seat without the Clicktight feature. In my opinion, it is worth it to pay extra for Clicktight because although it is significantly more, I’m willing to pay more to ensure a safe installation each time. This is especially helpful if you are planning on switching the car seat between cars.


Because of its steel frame, the Britax Frontier is very heavy, making it somewhat of a nuisance to move between cars. It’s kind of a unfortunate because it’s easy to install given the Clicktight feature, but also a hassle because of the weight of it.

However, it’s worth it to me to have the extra safety, even if it means a heavier car seat. I honestly don’t mind having a heavier car seat because I don’t switch my car seat between cars much, but if you are someone who does, this is something to consider.

Not a backless booster

Many convertible car seats that convert to a booster do so by removing the back. The Britax Frontier Harness-2-Booster does not do this. While I don’t necessarily see this as a problem, I know some people would prefer to just use the bottom of the seat as a booster seat but that is not a function on this model.

You can find more booster seat reviews in our Best Booster Seat article. Many of those choices evolve into a backless booster.

Not an all-in-1

The Britax G1.1 model is a Harness-2-Booster seat and has a minimum weight requirement of 25 pounds. This is a seat that you might use after a infant or convertible seat – it is a front-facing only car seat and is not for children under 2 years of age. While it will last you a while because of it’s wide range weight allowance, it is not a 4-in-1, which I know many people look for in a car seat.


As I mentioned above, the Britax Frontier Harness-2-Booster with Clicktight is one of the most expensive harness-booster combinations on the market. The added expense comes from the Clicktight and other safety technology, so in my opinion, it is worth the high cost.

Ease of Use Ratings

Car seats sold in the United States are safe because they have to pass the same safety tests and meet certain federal standards. The National Highway Traffic Safety Administration (NHTSA) gives every car seat a rating based on Ease of Use. Research has shown that mistakes in the installation and operation of car seats are a significant issue.

The  Britax Frontier in forward-facing mode received an overall rating of 4 stars. 4 stars is a good rating from the NHTSA. It also received 4 stars as a Booster seat.

My Recommendation

Britax G1.1 Frontier Clicktight Combination Harness-2-Booster Car Seat

I’m someone who is always looking for a bargain and I don’t mind using cheaper options for most products. However, there are certain items that I don’t mind spending extra on for extra peace of mind and a car seat is one of those items. All car seats meet minimum safety requirements, but I like that this one features Clicktight and extra impact protection technology. You will get years of use out of this car seat, too, so spread out over time, I think the cost is not so bad. I know I already talked it up, but Clicktight technology is life-changing. It makes it so extremely easy to install and is definitely worth the extra cost upfront to save the hassle later. I am so happy that I paid extra for this feature, and I believe most people would agree.
