Car accidents do happen, so you should make sure your child is as safe as they can be in the car. There are a lot of different baby car seat manufacturers in the market. This makes the right choice even more challenging.

In this Britax Roundabout G4.1 review, we will outline some important aspects of this highly regarded Britax car seat and help you decide if it might be right for you.

Britax Roundabout G4.1


Britax is a British childcare company which has been around for more than 70 years.

Their pursuit to push the standards of child safety has made them one of the best-selling baby car seat brands in Europe.

They came to the US market in 1996 and have since earned the trust of many American parents.

The thing that makes Britax stand out from the competition is their commitment to continuously improve the design and safety of baby car seats. They are constantly in touch with parents, legislators, and car manufacturers to ensure that their products are up to par with the needs of contemporary customers.

More than 20 years ago Britax began using energy-absorbing foam (EPS) in their baby car seats. EPS ensures baby protection in case of side-on collisions.

Improvements to car seat headrest and external cushions followed in 2002 and 2009. The headrest absorbs energy and the cushions were the first to feature energy-diverting compression.

What’s more, their mission is to go beyond the requirements of federal baby car seat safety standards.

SafeCell is the company’s integrated impact-protection system launched in 2010. 

The system is unique to Britax and it features a 2-strap V-shaped tether to limit seat rotation and staged-release stitches to restrict forward movement in case of a crash.

A 2005 research study at the University of Chicago confirmed the NHTSA’s estimate that three out of four baby car seats were incorrectly installed.

This is the reason why Britax introduced ClickTight technology in 2013.

This mechanism ensures easy and error-free installation for the highest protection of your child.

The Britax Roundabout car seat was first introduced in 1997 and has since gone through many iterations featuring the abovementioned technology.

Is Britax Roundabout the Right Choice for You?

The Britax Roundabout, now in the latest G4.1 release, is designed to fit the needs of any parents.

Even if this is your first baby car seat you shouldn’t have any problems installing it in your car. 

The ClickTight technology usually makes the installation quite simple. You don’t need to thread the seat belt or disassemble the seat to find the seat belt path.

Depending on the age of your child, you can install the Roundabout G4.1 forward or rear facing. The G4.1 car seat is suitable for children weighing 5 to 40 pounds. But, when it’s forward installed, children who are 20 to 55 pounds can use the seat.

The Britax roundabout is in the medium price range. But, the number of features it comes with allows the G4.1 to compete with some pricier models. In the grand scheme of things, the Britax Roundabout is potentially the best value for money.

This baby car seat also performs really well in the crash tests. Crash test sensors measuring the G-force on the head and chest of the dummy showed that the G4.1 met or exceeded the relevant federal safety standards (FMVSS 213). And the SafeCell technology should provide additional protection in the event of a crash.

When it comes to ease of use, there could be some room for improvement. This is probably because you need to rethread the harness if you want to adjust it.

Overall, the Britax Roundabout G4.1 would be a good medium-range option form most parents. It is not overly pricey while providing sufficient protection and usability.

Unboxing the Britax Roundabout G4.1

The G4.1 ships in a branded cardboard box. The overall shipping weight is a hair above 20 pounds. In the box, you will find the Roundabout Convertible Car Seat and a removable pillow.

 The lightweight and compact design of this car seat are some of its best features.

The G4.1 won’t bother other passengers in the car or collide with other car seats if you have any already installed.

The G4.1 seat cover is not marketed as machine washable. But this only means you have to take extra care if you wish to put the cover in a washing machine.

Make sure to use the gentle cycle without spin drying. To remove the seat cover you have to take off the harnesses, but they are easily removable.

The Britax Roundabout doesn’t come with a cupholder, travel caddy, or back massager. You may also want to consider a waterproof seat liner to protect the G4.1.

A vehicle seat protector may come in handy because the rubberized mat can catch spills and prevent scuff marks from your child’s shoes.

Britax Roundabout G4.1 Features

In this section of the Britax Roundabout G4.1review, we will take a closer look at some of the unique features. Additionally, we will outline the pros and cons of the Britax Roundabout car seat.

Handle Free Recline Adjustment

It is easy to use, but if you install the seat rear-facing, you won’t be able to reach the handle. 

Because you need the recline adjustment in the rear-facing position, you should adjust the recline before the installation. The proper recline is when the seat line is parallel to the car floor.

Easy to use Buckle

The buckle on the Britax Roundabout could have been better. However, it is comparable to some other higher-end models. The buckle won’t hurt your hands and is overall easy to use. But the G4.1 doesn’t come with a non-rethread harness.

This might be a hassle since rethreading can be time consuming, and you would have to get your child out of the seat. But, the threading slots are big and easy enough to use.

Several Position Adjustments

The G4.1 features 4 shoulder-height positions along with 2 forward-facing crotch positions and one rear-facing crotch position. The same splitter plate is used for both straps and they are easy to use.

LATCH System

The tightening strap is at the seat foot, but the loosening lever is under the cover fabric near the foot. You can easily reach and use both of them.

The LATCH storage is handy because the anchors are on the back of the seat. The backside pocket allows you to store the excess straps.

Very Comfortable. Nicely finished.

The Britax Roundabout features a slightly rougher fabric than some other models, but it is still very comfortable. It wraps nicely around the shell and you can easily remove it from the seat. The padding is also well made and when your child grows taller you can use soft strips located in the G4.1’s head area.

There are a lot of cracks and grooves on the shell of this seat. The Britax Roundabout G4.1 doesn’t feature an adjustable headrest so the seat may be a bit easier to clean.

Generally, the G4.1 comes nicely finished and your baby would fit nicely inside. However, there are some edges and corners on the bottom which might damage the seat of your vehicle.

As for the Britax Roundabout g4.1’s dimensions, we consider it a medium- to a bigger-sized baby car seat. It weighs 17.6 pounds and the dimensions are 21 x 18.5 x 26 inches.

These dimensions put it somewhere in the middle when compared to other baby car seats.

Alternatives to the Britax Roundabout G4.1

There are two other baby car seat models from Britax that you might want to check out. However, each of these models comes at a higher price than the Roundabout G4.1.

Britax Boulevard ClickTight Convertible Car Seat, Circa

This is their top-of-the-line car seat. It is also very heavy at 28.7 pounds. Also, the Boulevard ClickTight has somewhat lower crash test scores than some other models.

But, this fact shouldn’t concern you because the quick and error-free installation levels out the lower crash test score.

The materials are of high quality and the seat is very comfortable. It also features a honeycomb component which adds extra safety in case of a crash.

The recline adjustment handle is positioned in the same place as the Roundabout G4.1, so you should set the recline before the installation.

Britax Advocate ClickTight Anti-Rebound Bar Convertible Car Seat, Circa

The Britax Advocate ARB features both belt and LATCH installation which ensures a tight fit of this baby car seat. Overall, it is easy to install, very comfortable, and functional. But, its price tag is a bit steep and it’s the heaviest of the three seats.

Although the Advocate ARB has an anti-rebound bar, three layers of protection, and impact-absorbing base, its crash test results are a bit disappointing.

The abovementioned features should provide extra safety, but it hasn’t bored out in tests. If you are looking for a higher-end baby car seat, the ultra-comfortable Britax Boulevard might be a better option.


The combination of affordability, safety features, and easy installation makes the Britax Roundabout G4.1 one of the best options available on the market.

We hope that our Britax Roundabout G4.1 review has helped you make up your mind or at least narrow your search for a baby car seat that best fits your needs.
