My Honest Experience-Based Review

1. Design

britax marathon clicktight convertible car seat reviews

Britax Marathon ClickTight is a classic two-in-one convertible car seat with a rear-facing and a forward-facing mode. It supports children between five and forty pounds in a rear-facing mode and from twenty to sixty-five pounds in a forward-facing mode.

What makes this convertible exceptional is the easy installation and adjustability. A whole range of patented features works in favor of convenience and stress-free use.

Britax seats feature high-quality, durable structures, so they are on the heavier side. This model weighs 28.5 pounds. Therefore, I would not recommend it for traveling and flying.

I find the overall design of this seat fantastic. Quality and durability can be noticed at first glance, and since its expiration date is ten years, it’s unnecessary to comment on longevity.

2. Installation

Installation is pretty straightforward. The seat has a patented ClickTight system that allows effortless seatbelt installation.

Simply push and turn the ClickTight panel at the front of the seat to open the convertible and see the belt path. Then thread the seat belt through the belt path and buckle it up. Close the convertible, and Britax Marathon is ready to use.

The rear-facing installation features a LATCH, hidden in the LATCH compartment at the end of the seat. On both sides of the Britax Marathon, you can see level indicators that help you position the seat at a perfect angle every time.

To install this convertible perfectly every time, watch the following videos: Rear-facing LATCH installation and Lap-shoulder belt installation.

3. Adjustability

What I can say with certainty about Britax is that they produce the most adjustable car seats on the market. Britax Marathon ClickTight features fourteen headrest-harness positions and seven recline positions. With these optimizations at your disposal, you can achieve the perfect fit every time in both positions.

The seat also includes removable cushions, providing neck and head support to your newborn.

Adjustability is most certainly a strength of Britax Marathon, I would rate it 10/10.

4. Safety

When it comes to safety, Britax is a brand I often rely on. Despite the issued recalls in the past, they manage to stay at the very top of the market list as one of the most trustworthy car seat manufacturers. It exceeds all the federal safety standards and can be used in an airplane.

Britax Marathon ClickTight has an integrated steel frame, holding the entire structure sturdy and stable. Patented SafeCell Impact Protection forms an energy-absorbing shield around your child, protecting him/her in case of collision.

Additionally, a V-shaped tether and energy-absorbing base move the energy away from your child, being the last step in the protection.

Safety won’t be an issue with Britax Marathon ClickTight gets 10/10.

5. Comfort and Maintenance 

Britax integrates only the highest quality materials into their car seats. Your child will enjoy the supreme comfort and soft cushioning with no adverse effect on the skin. The covers are removable for easy cleaning and you can simply throw them into the washing machine for minimal effort.

6. The Final Verdict

For a two-stage convertible car seat, Britax Marathon ClickTight is an excellent car seat.

It has a standard weight range, a strong, reliable structure, and a thick layer of soft padding. With a series of adjustments, easy installation, and nifty details, it definitely falls into the group of the highest quality products.

As for the market competition, Chicco Next Fit is a product similar in price and quality to Britax Marathon. They have the same weight range and almost identical features. Chicco is a bit lighter and has nine recline positions, as opposed to Britax seven. Yet Britax offers five more headrest positions, and it’s a bit more affordable. Whatever of these two you choose, you will make the right choice.

Finally, here is the list of advantages and disadvantages of Britax Marathon ClickTight:

Pros
  • Easy to install
  • Adjustable
  • Safe
  • FAA-approved
  • Strong
  • Reliable
  • Standard Weight Range
  • Not too expensive
Cons
  • Too heavy

All in all, I honestly recommend this car seat to all families in search of a strong, reliable seat that will last long and won’t fail to deliver!

Keep them safe!

Final Thoughts

After everything said, I can only conclude that Britax ClickTight is a car seat I would buy for my child without a single doubt in my mind. It exceeds federal safety standards, comes with a bunch of useful additions, and can be adjusted to accommodate your child perfectly. You won’t even have a problem with cleaning, and your child will enjoy the super-comfortable cushions.

The only thing that may be a bit inconvenient is the weight. With that in mind, this is not the car seat you want to bring to the airport or carry along to another country.

Yet, for day-to-day use, it is perfect!
