Customer Reviews
Safe & Comfortable at a premium![]()
The Britax Marathon CS is an upgraded version of the regular Marathon. The only difference is the CS, Click & Safe Harness Adjuster, which tries to notify you of the proper “snugness” of the harness with audible clicks. What most Amazon readers probably want to know is, is this car seat worth the premium and how is it different from the other Britax models? Hopefully this review will help you make the best decision for you, but I cannot provide a definitive answer to the question of whether it is worth the premium. It is to my family.

The Marathon is one of 4 high-capacity convertible car seats that Britax currently sells. The others are the Britax Decathlon, Britax Boulevard, and Britax Advocate CS. The Marathon and Boulevard are also sold with CS (Click & Safe). From what I can tell, the Marathon and the Decathlon have smaller bases for installation in smaller vehicles. The Decathlon has an infant body pillow and multiple buckle positions, but otherwise, it is similar to the Marathon, including height and weight ratings. The Boulevard and Advocate CS are very large yet still have the same child size ratings, but incorporate what they call True Side Impact Protection. The Advocate is their most advanced, and expensive convertible, because it adds Side Impact Cushion Technology.
The Marathon CS is one of three Britax car seats that we actually own. We started with a Boulevard 2 years ago and recently got an Advocate CS and the Marathon CS. We installed the Marathon CS in our Jetta in a forward facing position for our toddler. The Marathon is smaller than the Boulevard and Advocate and it actually fit our Jetta quite well. It wasn’t so tall as to block our rear view at all and the front seat could still be far back enough to be comfortable for adult passengers to ride in. The smaller size was the main reason we decided on the Marathon for our toddler. If we had more room, we probably would have gotten the Boulevard or Advocate, which are both in our larger, Toyota 4Runner.
The LATCH installation took me 5 minutes, no lie. I have some experience installing car seats and I watched the installation video and read the manual before installing so that may have sped up my install time. I recommend that new owners do the same. The push-button LATCH connectors are so easy to hook on and tighten that it was almost too easy and I got paranoid. I took the seat to our local police station for a car seat check and they gave it their blessing.
Our toddler really likes the Marathon and sits comfortably in the seat. The shoulder and belly pads help make it more comfortable. However, the police officer recommended that we remove them because they can hinder getting the correct harness tightness. The Click & Safe system is supposed to help alert you when the correct snugness has been reached, but from my experience, it’s not really that useful.
The service life for Britax car seats are 6 years from the manufacturing date. I had to look this up on their website, which has a lot of useful information including installation videos and user guides. It would be nice to have the expiration date located right on the serial number sticker. Until recently, I wasn’t aware that car seats even had an expiration date. The serial number can be hard to find on the car seat itself so be sure to make a copy of your registration card, which has all of the information on it.
For me, there are only two drawbacks to the Marathon. The first is that in order to adjust the harness height, you have to rethread it. This means that if you have it forward facing, you have to remove the seat to do it. The second, is the price. We could have easily bought two of the Consumer Reports Best Buy recommended Evenflo models for the price of one Marathon CS. We decided on the Britax anyways because of the number of safety features available along with our previous experience with Britax. The fact that the car seat technicians at the police station and AAA both said that they chose Britax car seats for their children, only reinforced our decision.
We are very happy with the Marathon CS. We feel confident that our toddler will be safe and comfortable in the Marathon and that it will easily last the full 6 years of service life. It is not the best value out there for sure, but that wasn’t our number one priority. I can only justify the cost for ourselves and I certainly would not fault anyone for going with better value alternatives.
Versatile and (Generally) Easy to Use, but Most of All – Secure![]()
The Britax Marathon convertible car seat is definitely pricey, but it makes good on that investment by its versatility. It can handle not only smaller kids in a rear-facing installation, but also larger kids if it’s place forward-facing – up to 49 inches and/or 65 pounds. That’s considerably longer use than most convertible seats allow. However, in order to do so, the Marathon needs to be taller than other convertible seats – this is a very large unit and may not fit well in smaller cars.
INSTALLATION
The Marathon is equipped to be tethered via either the LATCH system or else standard seat belts. LATCH installation was extremely simple, as it is with just about every other car seat. However, if your car is older and doesn’t have LATCH hooks, then seat belts are you only option and in most cars this is a dreaded exercise in pushing and tugging to get the seat sufficiently tightened down. The Marathon was a pleasant surprise – I was able to get it installed forward-facing with a lap-and-shoulder belt with much less effort and frustration than any other car seat I’ve ever used before. The anchoring points on the seat itself are visibly strong – iron bars that the seat belt easily loops through. Other seats make it difficult to see/feel if the belt is threaded correctly and not twisted, but this is easy with the Marathon.
For additional security, I also used the Versa-Tether strap that connects the top of the seat to an anchor in your car’s back deck or your SUV’s cargo area. This was also easy to install and once I’d pulled it tight, the seat was absolutely rock-solid. Installed this way, the Marathon had much less wiggle than any other car seat I’ve owned.
USAGE
The Marathon touts its “Click and Safe” system for tightening the harness once your little one it seated. However, I found this to be a detractor for a couple of reasons. First, you tighten the harness by pulling downward on a strap that dangles from the front of the seat. You must pull it straight down/forward, which can be difficult to do since you’re reaching into the car from the side, especially in a car that’s low to the ground. I prefer the design of other car seats that puts the tightening mechanism on the side via a knob. Also, it claims that the harness is sufficiently tight once you hear a click, but I wasn’t convinced – the straps always seem to have a little too much slack after the first click, so I end up fiddling around with them for a while until it passes the test. This can often lead to a fussy passenger. Loosening the harness, on the other hand, is very quick and easy.
Also, every kid will be different, but my two-year-old complains (sometimes pretty forcefully) when being buckled in to the Marathon. I think that it has a wider buckle in the crotch than our old car seat did and that must be uncomfortable. However, after he’s in for a few minutes, he never fails to tell me that he likes the new seat, especially the neck protectors that keep the harness straps from digging in.
MAINTENANCE
I really appreciate the open-back design of the Marathon, not only for the ease of installation described above, but also because it makes it easy to adjust the height of the harness and remove the cover for washing. Other car seats often conceal the back within a clamshell which then requires tools to remove anytime any such adjust or maintenance needs to be done.
SUMMARY
The Marathon is not perfect, but close. It’s also pricey, but a worthwhile investment given how long it can be used. I highly recommend it as a consideration when you’re shopping for a convertible car seat, especially if you have a roomy back seat and a higher-sitting vehicle.
great car seat.. comfortable, well made.![]()
The Britax Marathon is a larger car seat that supports from a five pound infant (rear facing) up to a 65 pound child (forward facing). The seat is very comfortable for our 13 month baby–judging by the long naps she takes in it. The seat has well-labeled, heavy clamps for securing seatbelt straps. There are multiple ways of anchoring the seat, which can be confusing, but the helpful decals and attached manual (it stores under seat cover) help you figure it out. For cars with car seat anchor bars, there are easy latches with buttons that make installation very easy.
The seat is pretty large and deep. The bucket shape is apparently designed for side impact protection. Overall, this is a very nicely designed and built carseat.
Pros:
- Quality, furniture-grade fabric/upholstery.
- Accommodates from small infant to larger children.
- Plenty of anchoring options which are well-explained.
- Very comfortable.
- Energy absorbing features such as tether which gives under stress and impact foam.
Cons:
- One size fits all approach: you can use this seat for a longer amount of time, but it takes up more space in your car. The height makes it a little harder to put a child in compared to our Britax roundabout (rear facing mode).
One final comment about the new click & safe feature. We didn’t really understand it. We listened for a click when tightening straps but didn’t hear one. This doesn’t distract from what is an excellent product in our opinion.
