Formerly present only in Europe, the juvenile products of Britax have arrived to America over twenty years ago and have been building an excellent reputation for the company on the other side of the water. Their car seats are innovative and stylish, but also safe and manufactured with protection in mind. The Frontier G1.1 certainly isn’t an exception to this rule – it’s a great-looking booster car seat with some innovative features (like the “Clicktight”) and a construction that’s guaranteed to keep the kid safe during the long car rides. Let’s see what it has to offer!


  • Car seat type – Booster car seat

  • Weight limit – 25 – 120lbs

  • Height limit – 57″

  • Dimensions – 21″ x 19″ x 24″

  • Weight – 24.9lbs

  • Number of harness slots – 5

Features of Britax Frontier G1.1

  • The Design

Like all other car seats manufactured by Britax, this one also sports an almost impeccable design. It’s a huge, well-constructed booster seat that can be purchased in four different color variants. We had the “Vibe” version on a review – it’s a beautiful combination of gray, black, and red colors.

Even though it’s quite heavy, the Britax Frontier G1.1 actually sports quite a slim design, making it a perfect choice for the owners of compact sedans. This can especially useful if you’re a parent of multiple children and want to put more than just one seat on your vehicle’s back seat.

We also liked the fact that the G1.1 is more open on the sides, giving the kid a much more clear view of the world. One can also purchase a number of handy accessories for this model, but more on that later.

  • The Comfort

One of the most underrated features of this model is that it allows a parent to find a specific fit for his kid. Sure, it’s possible to get lucky with an inexpensive model that has the right size for your child, but, for most of the time, the so-called “One Size Fits All” feature doesn’t really work as advertised.

That won’t be an issue with the G1.1 – its harness can be adjusted without the need for reassembling or rethreading. This will allow you to adjust the head restraint and the harness to shoulder height with incredible ease.

Since this is a seat/booster combo, you’ll be able to use it for a very long time. It sports a 90-pound weight limit in its harness mode, which is quite impressive and easily beats a lot of other seats made by the competition. And once you switch to the booster stage, the weight limit rises to 120 pounds, allowing you to keep the kid safe from the toddler age all the way to adolescence. Britax claims that the lifespan of this booster car seat is nine years, which is quite remarkable and deserves some special praise.

  • The Safety

Just like we expected, this booster excels in the field of safety. The G1.1 comes with a full-steel frame that’s embedded in the seat and has been designed in a way that absorbs impact. It is also surrounded by the energy-absorbing foam liner that helps to evenly distribute the forces that appear in the case of a traffic accident.

The V-shaped tether and the model’s base also absorb energy and so do the seat’s deep shell and the headrest. When we combine all of this, we get one of the safest booster seats on the market right now – with it, you’ll have a complete peace of mind while you’re driving the car together with your little one in it.

The Clicktight feature that we already mentioned is the thing that sets this model apart from the competition. Basically, this is an automatic seat belt installation system which removes all that tugging and pulling and replaces it with an incredibly easy process. All you’ll have to do is to pass the vehicle’s seat belt through the green pathway, buckle it, and then close the cover. This can be done in just a few moments and is undoubtedly one of the most impressive features of this model.

  • The Acessories

The owners of this model have a chance to purchase plenty of useful accessories for it. Some of them are:

Vehicle seat protector – made out of non-slip material, it protects the seat from scratches and markings. It can also catch crumbs, dirt, and spills.

Travel cart – this is a very useful accessory for the parents who travel a lot. The G1.1 is a heavy seat, and the travel cart will help you transport it from, say, airport to your vehicle.

Cup Holder – even though the Frontier comes with its own set of cup holders, you cannot remove it. This set, on the other hand, is portable and dishwasher-safe.

What’s wrong with the product?

  • The booster is heavier than we expected

The Britax Frontier G1.1 is among the heaviest models we have reviewed so far – it weighs almost 25 pounds and moving it around isn’t exactly an easy task. Fortunately, there’s the Travel Cart accessory that can be purchased separately to make this a bit easier.

  • It’s quite pricey

A model with so many useful features and a premium construction is bound to be very expensive. This is not a budget-friendly model, but don’t forget that its expiration date is nine years from the date of manufacture – it’s the only car seat you’ll ever need.


Those who are not on a tight budget and want to buy a car seat that will last them for years should definitely consider the G1.1 for purchase. This is one of the best models we have ever reviewed – it excels in almost every field, and is a clear winner in the category of booster car seats. It is very safe, effortless to use, and comes with a long lifespan – what more could one want from a car seat?
