Your child’s safety is very important because of the high number of road accidents.

I have also included some safety tips that can help you avoid the most common mistakes parents make when they use these car seats.

The NHTSA issue’s safety ratings for more than 100 convertible car seat design each year. They measure the seats’ performances using the following safety factors:

Three Convertible Car Seat Mistakes You May Be Making

You Forget to Secure the Seat’s Belt to Your Vehicle
It is a good idea to secure the seat’s seat belt to your vehicle’s interior it can prevent head injuries that happen when your vehicle is hit from behind. An easy way to avoid this mistake is to secure the seat’s belt to your vehicle immediately after you put the harness on your child.

You Allow Your Child to Face Forward Too Soon
According to the American Academy of Pediatrics, All Children below two years should remain rear-facing. Doing this can prevent most shoulder and chest injuries that occur when children face forward too soon in their car seats.

The Harness Slots Are in the Wrong Spots
Many convertible seat designs feature three sets of harness slots. The lower two are used for the rear-facing position, and the upper set is used for the forward-facing position. Some parents forget to adjust the upper set of harness slots when their children are facing forward. Doing this is a bad idea because it could cause your child to be thrown from his seat during a rear-end collision.

Safety Features

Marathon ClickTight Features

SafeCell Impact Protection

One major safety feature is the SafeCell Impact Protection system, which is unique to the Britax brand. In addition to keeping your child from being thrown in a crash, the purpose of a car seat is to absorb the energy of an impact, much like a bicycle helmet.

The Marathon ClickTight includes a number of innovations that work together to limit the effect of a crash on your child.

Side Impact Protection

Just like all new luxury cars, the SafeCell system includes several protections from dangerous side impacts. First, the seat’s sides are deep enough to completely protect your child from any kind of flying object or debris that may come in from the side. Second, the headrest is thick and soft on all sides in order to protect your child’s neck and head in an accident. Lastly, cushions on the external parts of the seat absorb additional energy and even protect passengers sitting next to the car seat.

Impact-Absorbing Base

The ClickTight’s base has a special energy-absorbing feature that makes the seat extremely stable. In case of an impact, the base will compress and divert the energy from the chair. This helps keep the chair from lurching forward and colliding with the seat in front of it.

V-Shaped Tether

Another element of the SafeCell system is a two-strapped tether that works to keep the chair from twisting or rotating. It will pull apart in an accident, which absorbs some of the impact and keeps the chair from moving too far forward.

Steel Frame

Many parents will appreciate the knowledge that their child’s car seat is reinforced with a strong, steel frame. This reinforcement keeps the seat from bending or twisting, which will help keep it intact.

Safety and Easy Installation

ClickTight Key

ClickTight Installation System

Trying to install a car seat can be one of the most frustrating daily tasks parents must do—and there can be serious consequences if it’s done wrong. Luckily, this car seat’s ClickTight system makes it pretty fool-proof. You just push a button, open up the seat and slide the seat belt through the slots. The seat easily clicks shut. It’s almost impossible to do wrong.

7 Position Recline

Since every car is different, it’s helpful to be able to adjust the angle at which the seat reclines. This seat has a full 7 different position to fit a huge range of cars, from ‘big to small’.

Automatic Level Indicator

There’s an Automatic Level Indicator to make it easy to choose the right position for your child and for your car.


Marathon Quick-Adjust Technology

Quick-Adjust technology

Britax convertible car seats use Quick-Adjust technology, which makes fitting the harness to your child a snap. Pushing the red button on top of the seat and pulling up the handle allows you to choose one of 12 positions without a hassle. This is very convenient as the child grows. A correctly fitting harness is also necessary for safety.

EZ Buckle

Many car seats make it annoyingly difficult to fasten the buckle between the child’s legs once they’re sitting in it. You have to search around beneath or beside them, all while they’re wiggling and trying to slide out of the seat! The Britax Marathon has solved this problem with what it calls the EZ Buckle, which has a pad that holds the buckle out of the way while you get the child into the seat. Once the child is settled, the buckle can be moved to the other position.

Extra Comfort Pillow

This seat also comes with a very useful additional body pillow for supporting new and smaller babies, who often seem to get lost inside a big car seat. This cushy pillow supports them underneath on either side so they don’t slide around. This pillow is easily removable once the child can sit up properly on his or her own.

Thick Padding

The Marathon is lined on all sides with very comfy, squishy padding, which is nice for the child but is also a safety feature. Padding on the harness absorbs impact, and padding in general helps the child fit securely in the seat. The harness padding may actually be too much for smaller children and get in the way of a good fit, but it can be removed. It is a little tricky to do this; however, since you have to re-thread the harness through the back of the chair.

Design and Specifications

This Britax car seat weighs 29.4 pounds and is 18″W by 23.5″ H by 23″D. It is designed to fit children from 5 to 40 pounds in its rear-facing position. In the front-facing position, it will fit children between 20 and 65 pounds. Also, children can be up to 49″ tall to use this chair.
