What Makes the Britax Marathon ClickTight Convertable Car Seat so Special?

What Are The Size Requirements Of The Britax Marathon ClickTight Convertable Car Seat?

This car seat is made to grow with your baby from infancy through toddlerhood. As experts have shown, rear facing is the best safety position for your child. With the Britax Marathon, your child can ride in the far safer position until they reach 40 pounds.

Many parents in the United States turn their babies to the front-facing position after only one year. However, remember that the Britax Marathon ClickTight Convertable Car Seat is a European model and in Europe, parents keep their children in the rear-facing position up to age four. If you opt to let your child remain in a safer position, remember that you will have to stop using the car seat’s LATCH feature at 35 pounds.

Here are the size requirements of the Britax Marathon:

  • Rear-facing: 5 to 40 pounds. Head remains one inch below the top of the headrest in the rear-facing position
  • Forward-facing: 20-65 pounds with a 49-inch height range

Is The Britax Marathon ClickTight Convertable Car Seat Too Big For Compact Autos?

The Britax Marathon may not work in a compact car due to its large size. Unfortunately, the three-seat configuration becomes almost impossible in a small interior so you will want to measure your vehicle before purchasing the seat. Also, placing the car seat in the rear facing position limits the leg room of the front seat passengers.

Here are the specs for the Britax Marathon car seat:

  • Weight: 18.5 pounds
  • Depth: 10.5 to 11.5 inches
  • Height: 23.5 inches
  • Harness Positions: 8.35 to 19.4 inches

Please remember that the Britax Marathon does not double as a carrier like other car seats. The model also has been designed to remain in the auto and adapt to your growing child.

How Safe Is the Britax Marathon ClickTight Convertable Car Seat?

The steel frame of the Marathon is solid and sturdy. Also, the Versa-Tether and SafeCell base are designed to absorb side impacts

In addition to the above stated internal safety features, the car seat also has a V-shape to minimize seat rotation in an accident. The stage-release stitching also slows and reduces any forward movement. Likewise, these features offer extra protection for your baby’s head, spine, and neck when placed in a forward-facing mode.

The LATCH feature’s weight has been lowered to 35 pounds for rear-facing, but this car seat’s weight limit remains at 40 pounds which sets it ahead of other similar car seats for safety. However, please remember that you will have to stop using LATCH at 35 pounds if you do not turn the chair into the forward-facing position.

Is There A Safety Drawback To The Britax Marathon?

The entire point to purchasing a car seat is to keep your little one safe during an auto accident so you want a car seat with all the safety bells and whistles. If you are like most parents, you probably expect the car seat to include all needed safety mechanisms. Unfortunately, the Britax Marathon car seat does not include a rebound bar.


Undoubtedly, a rebound bar protects against rearward movement if your auto sustains a front or rear impact accident. The bar is soft and padded so your infant is always cushioned with the bar. Also, it makes a nice footrest for your little one in the rear-facing position, but it also keeps your infant safe.

Most parents consider the rebound bar a ‘must-have’ safety device, so they are faced with making the additional purchase when they buy the car seat.

Is The Britax Marathon Easy To Install?

Many parents report that this is indeed one of the easiest to install so that is one of the main reasons they list for purchasing the seat model. The ClickTight seat belt offers ease and efficiency that far surpasses other comparable car seats so you have peace of mind with your child’s safety.

To use the ClickTight feature follow these steps:

  1. To lift the Clicktight Panel, all you do is push and turn one button, and the seat panel lifts.
  2. Place your infant into the car seat.
  3. Thread the seat up through the belt path
  4. Pull up the slack using the lap belt
  5. Close the panel
  6. To adjust any slack, use the lap belt.

Unfortunately, the Marathon ClickTight cannot be used in auto models that have inflatable seat belts such as those found in Ford, Lincoln, and some Mercedes models.
