Chicco NextFit has a wider, larger overall size. This model measures 19 inches wide, 21 inches deep, and 29.2 inches tall. Because of the width, this model will not allow you to fit three units across the backseat of your car. However, you can still fit two units across the backseat.

That said,Chicco NextFit is quite a bulky seat. It has tall sidewalls which may hinder you when you are trying to put your child into the seat. This is less of a problem if your car is quite spacious so that you can position yourself in front of the seat when trying to get your child in or out. But using two Chicco NextFit car seats in a small car will probably be difficult.

Furthermore, Chicco NextFit is heavy. It is even heavier than Britax Marathon. It weighs about 28 lbs. So, this model is more suitable for a fixed installation in a single car. It is not suitable for traveling or portable use.

Britax Marathon is slightly more compact. It measures 18.5 inches wide, 23 inches deep, and 23.5 inches tall. However, this model still won’t allow you to fit three units across the backseat, unless you have a very wide car. But you can put two car seats across the backseat just fine.

The weight of Britax Marathon is about 25 lbs. It is a bit lighter than Chicco NextFit, so it will be a bit easier to set-up. It doesn’t have tall side walls that may hinder you when installing and using the car seat. However, this car seat is still quite heavy, so it is more recommended for a fixed installation and not for traveling or portable use.

Suitable Use
Of course, when considering a car seat, you should check the weight and height ratings of the unit. You should make sure that the car seat is suitable for your child, and that the car seat will not become too small for your child too quickly. However, Chicco NextFit vs Britax Marathon actually have similar weight and height ratings.

Chicco NextFit is suitable for an infant between 5 – 40 lbs when used in the rear-facing position. According to the experts, you need to keep your child in the rear-facing position for as long as possible, because this position is the safest with the lowest chance of injury. Make sure that your child’s head is at least one inch below the top of the headrest.

Meanwhile, in the forward-facing position, Chicco NextFit is suitable for a toddler between 20 – 65 lbs. The maximum child height limit is 49 inches. You will be able to use this car seat for several years before you need to get a belt-positioning booster seat. Chicco NextFit has 9 recline positions to suit the need of the child in any age; however, it is not recommended for a newborn because the high side walls will make it difficult to use.

Britax Marathon is also suitable for an infant between 5 – 40 lbs when used in the rear-facing position. It has 7 recline positions to provide the most supportive and comfortable sitting position for the child as they grow. This model is suitable for a newborn baby. You can put it in a rear-facing position and use the lowest recline level when using it for a newborn baby.

In the forward-facing position, Britax Marathon is suitable for a toddler between 20 – 65 lbs. The maximum child height limit is 49 inches, too. So, this model is practically suitable for most toddlers. It can easily accommodate a kid with a big physicality for a few years before you need to switch to a belt-positioning booster seat.

Between Chicco NextFit vs Britax Marathon, which one is easier to set up? Well, in general, both models are very easy and simple to set up. The difference is that they use different mechanisms.

Chicco NextFit comes with premium latch connectors and the company’s exclusive Super Cinch LATCH tightener. Many people say that the standard latch connectors are difficult to tighten; however, with Chicco NextFit, you won’t have any problem with the installation! Its connectors are easy to attach and detach, and the special tightener works very well in tightening the seat. Hence, you can easily achieve a perfectly solid and secure installation without much effort!

However, if your car doesn’t have the LATCH feature, you can still use Chicco NextFit. This model can also be installed using the vehicle’s seatbelt. It has two clips that will prevent the seatbelt from gliding away from the right place. So, the seatbelt installation is also secure.

Britax Marathon comes with the company’s proprietary patented ClickTight installation system. It works with the vehicle’s seatbelt, and it is extremely simple and easy to use. You only need to lead the seatbelt through the path and buckle the seatbelt to the connector. The set-up is completely solid and secure without much wiggling. A lot of parents love this installation system very much.

By the way, since the ClickTight installation system works with the vehicle’s seatbelt, it should be suitable for both old and new cars. Although this model also has standard LATCH connectors, using the ClickTight installation system is much more recommended. It is easy, quick, and reliable.

Harness System
Now, let’s compare the harness system of Chicco NextFit vs Britax Marathon.Which one is easier to use? Which one can provide a snug and secure fit for your child?

Chicco NextFit is equipped with an adjustable headrest. There are 6 headrest positions available. In addition, the headrest adjustment mechanism is integrated to the harness system. This allows you to change the harness position without having to do any manual re-threading. So, adjusting the harness is easy and simple.

Britax Marathon also has an excellent harness system. It is very easy and convenient to use, too. It does not require any manual re-threading at all. It has 14 harness positions and 2 buckle positions. So, it should be able to accommodate your child and provide the most secure and comfortable fit as they grow.

Seat Features
Chicco NextFit comes with a removable cup holder. This is great. You can attach the cup holder to the car seat when you need it. The cup holder is definitely very useful for holding your child’s milk bottle or snacks. However, you can just remove the cup holder when it is not in use, in order to free up some space.

The seat cover is actually removable and machine-washable. So, it is supposed to be easy to clean. Unfortunately, the process for removing the seat cover is quite difficult. There is another model called Chicco NextFit Zip which has a zipper mechanism to allow easy seat cover removal; but the non-zip version doesn’t have this feature. Keep in mind that you need to use cold water and a delicate cycle setting when cleaning it with a washing machine.

Britax Marathon does not come with any cup holder. However, you can buy the optional Britax cup holder accessory, which is sold separately. It attaches well to the car seat.

All of the fabrics are removable for easy cleaning. You can remove and reinstall the fabrics quite easily. The fabrics are machine-washable. However, some users say that the fabrics may get damaged if washed with a powerful cycle setting. So, make sure to use a gentle cycle setting when cleaning the fabrics. Or, you can just wash them by hands in order to avoid any risk of damaging the fabrics.

Both Chicco NextFit and Britax Marathon provide excellent safety and protection for your child. They both have been tested to meet or exceed all applicable safety standards. Both of the two models have been side-impact tested, too.

Chicco NextFit’s tall side walls are especially great for shielding your child against debris particles in the event of a crash. They also help to prevent impact forces from reaching your child. But Britax Marathon also does a decent job with the side impact protection layer.

Both models are FAA-approved for airplane use. So, although their bulky and heavy dimensions may make them unsuitable for traveling, it is still possible for you to use either car seat when taking an airplane flight. But, before that, make sure that your car seat will fit on the airplane’s seat by asking the airline company.
