The Marathon Convertible Car Seat is an excellent choice for getting your family where they need to go safely and comfortably. SafeCell Impact Protection surrounds your child in safety components that work together to protect well beyond the established federal safety standards. And Complete Side Impact Protection shields your little one in a deep protective shell designed to absorb crash forces and protect from debris.

A car seat works best when it provides the right fit so the Marathon comes with the Quick-Adjust, 10-Position Harness and 2-Position Buckle to keep up with your growing child. Installation is made simple with Easy-On / Easy-Off LATCH Connectors that lock into place with an audible click and are easily released with the push of a button. Plush Foam Padding provides premium comfort at every touch point and there are even 3 Recline Positions so your child can relax at the right angle.

The Marathon converts from a rear-facing position (for babies 5-40 lbs.) to a forward-facing position (for children 20-65 lbs.) to keep your child safe and you free from worry wherever the road may take you.

  • SafeCell Impact Protection is an integrated system of safety components that work together to protect your child well beyond the federal safety standards.

Love the marathon. I really was thinking of getting something more towards a booster and giving our old one to the baby but love how safe and secure this is for my kids. We previously had the onyx fabric but felt it was worth getting this pattern at a lower cost. The fabric is a little course but overall it is such a great sturdy seat. So glad I got this again.
Pros:
safe and secure, easy to install, great piece of mind
Cons:
getting it at the right recline can be tricky in the beginning.

Fantastic!!
January 13, 2017
I'm in love with this car seat! My son is only 5 months old, but he's never been a fan on the infant seat. He's small for his age, but he always seemed squished. This seat gives him the room he craves, but it's still safe for him (14lbs) to be in! He also loves being up a little higher so he can see out the window more now. It was easy to install with the LATCH system, too. And even at its size, it's FAA compliant!

This is my second Britax convertible car seat purchase. It's a great car seat, however I like the Onyx color car seat a lot better. The McCoy is ok. I don't like the material. But I'm not disappointed in the car seat for safety.

Fast Shipping! We ordered two of these car seats, one for our baby transitioning out of the infant carrier, and the other for our three year old. We installed one rear facing and the other forward facing in our GMC Sierra with ease. They tighten down with no movement very easily using the latch system. The straps adjust easily and it is easy to make adjustments to the shoulder height. The fabric is durable. Both kids are comfortable and safe!

This item was ordered for a friend's daughter who is having her first child. Safety was the most essential requirement. After a thorough review, this car seat was chosen. It is impressive because, in addition to safety, the car seat is constructed without the use of toxins. We're all crazy for the kiwi (bright green) color as well. We're also happy the car seat arrived so quickly. Customer Service was extremely helpful and courteous in providing us with the delivery date, as we had misplaced the order confirmation information.

Wonderful
December 31, 2016
So far I love this car seat. It is a nice size and my baby seems to like it better than the infant carrier seat. I will keep you posted on how well she does with it. I love the fabric. It's easy to keep clean. It's also very soft! I love the Velcro that holds the straps out of the way to put the baby in but still keeps them handy so you aren't digging for the straps under the baby. That is by far my favorite "small" thing about this seat!
Pros:
Very solid seat
Cons:
No cup holder.

We have loved this seat so far. I appreciate the Velcro on the sides that holds the straps out. My son seems to really like it, he falls asleep the second he is put in it!
Pros:
Velcro that holds the straps
Cons:
There are only 3 recline positions. Positions 1 and 2 aren't very different from each other.

My daughter and son-in-law purchased a chicco keyfit 30 and needed an additional car seat for their second car. Since they were not crazy about the Chicco, we explored different options and decided that I would give them this one as a Christmas gift-- to be opened early. They did have some trouble adjusting the straps so that they would fit properly, but eventually figured it out. They like it so much more than the Chicco. The design is much more open and easier to maneuver my grand daughter into and out of it and she does not feel quite as confined. Personally, I prefer the Diono that I use, but this one was a steal at the price. Very happy with the purchase.

We bought one for our daughter when she was 2 months old, she hated her carrier carsea . But as soon as we got her britax in car rides became so pleasant. So when we found out we were expecting baby #2 we decided to have a Britax on hand. The price on this sight was the best we have seen for this style. We love this style because it cleans off so easy, and will not show dirt or stains easily, considering kids can be messy. Our item shipped fast and we received it without any problrms.

I bought 2, which brings my total of Britax Marathon's to 4. The Jet set color was a great bargain and I love the seat. I saw no reason to get another model when we had the second child. I think they easy to use and provide great protection. I see no reason to spend more money on the other brands. They fit perfectly in both hour vehicles and one of them is a Ram 1500 Quad cab with a shortened passenger compartment.

We drive a Jetta. I was pleasantly surprised that this car seat gave more room for the front passenger than our infant dead did. It was easy to install, even with my stubborn latch on one side and even easier to adjust for my baby's size. And the price...it can't be beat!!!

This has the features I need
September 4, 2016
I like this design better than than the one that feeds under the seat then clicks, because numerous times I find it handy to unlatch and carry sleeping baby and car seat in for continued nap. Also this seat is light enough to do that with. I like the quality of the buckle mechanism. I tried another brand and returned it. I do not miss the cup holder feature. This stream lined design is much easier for getting baby in and out. I am the grandma and have only used this seat in forward facing position so far.

Easy to install and even easier to adjust the settings plus excellent safety ratings & great manufacturer assistance if needed. With this price & quick delivery we will definitely be back for our 6th seat once the baby outgrows the infant seat.

This car seat has been even better than expected. I knew it would be a great seat, but my daughter is so much more comfortable in this seat than the infant seat. Another plus is the size. It's in the middle seat, and j can easily fit two boosters on either side. No issues. Love the color, very easy to adjust. Great buy!

I was able to get this car seat on sale for $199. I did a lot of review and found that this car seat is good for safety with out the extra stuff that jacks up price. It fits well in my SUV and my husbands truck, it is a little difficult to adjust to the 2 different seat angles. My son is able to sleep well on long car rides.

This is the third Britax Marathon seat we've owned. The seat cover is not as soft as the other models we had before and that is my only complaint. It's not itchy, just not as soft. The seat was pretty easy to install and the straps are easy to adjust.
Pros:
Easy to adjust the straps, compared to older versions
Cons:
Fabric not as soft as older versions
Best Uses:
Babies 6months and up. A newborn would be swallowed up in this thing.

Loved the reviews, especially the ones that said this was not the first time they bought from this company.. that is an outstanding recommendation. Lots of good aspects to this particular carrier.. yes. we are extremely happy and so are the parents to be.

Excellent
February 4, 2016
We have an older marathon and were impressed with the updates on this model. We love the back belt adjuster that you can adjust for height by a simple click and pull instead of taking belts in and out of the back of the car seat. The new seat base is nice because you can set the seat on the ground without it toppling over. Our baby is 19 lbs, 3 months old and the infant seat rest works great. Finally, installation is quick and simple especially if you have a latch system in your vehicle. You can't beat Albee baby's prices or the fact that britax has the same price on this seat that they did roughly 10 years ago.

Great car seat
November 18, 2015
The directions for installing the car seat were actually quite easy to follow and the seat seems to be well-made overall. We have a Prius, and it fits just fine in the back seat, with the only issue being that because the rear Prius doors are lower profile, there's not much clearance for getting the little one in and out. (We installed it rear-facing -- our daughter is under 22 pounds.) But we've had it installed for just over a week and I'm already used to it and finding that easier. The car seat was delivered in two days, too! We originally chose this car seat because Britax has an excellent safety reputation and seems to do a better job overall not using untested fire retardant chemicals, but it's also just a great car seat. I can imagine it will hold up well for a number of years.

Big britax fan!
September 17, 2015
I first experienced a britax seat w my first child, now 8. I bought him the britax frontier. Quality...through and through. When my new baby, now 5 months old went to his 4 month well visit he weighed 19lbs2oz. The time had come to find a convertible car seat. Right away I leaned toward britax. I have a Saturn ion. My car is small, mostly plastic...and I drive 70 miles of round trips a couple times a week on a highway and into the city of buffalo, N.Y.. crazy, disrespectful drivers. So I knew I needed some serious side impact protection and a steel frame. High weight limit for my big baby boy, as I hope to rear face him til he's 2! His daddy mentioned he'd love a green seat. Then I came across the britax marathon in kiwi! Love it. Installed easy. Easy to use. I wasn't big on the infant positioning pad or the huge belt protectors on the neck straps. I ended up getting thinner ones and not using the pad. All in all...love it. Glad a spent a little extra for the britax!!

The Marathon is a great carseat. Having all the safety features we want and the ease of adjustment makes us very happy. Tightening of straps took a little getting used to for our rear facing 19 month old because we are not used to the grey pieces by the chest clip, but it just took a few times of working with it to get it down. It feels very sturdy and yet feels comfortable for our child. We are very happy with this purchase.

Great car seat
August 30, 2015
This car seat is extremely well made, as well as attractive. It fits behind the driver seat of our Subaru Forester (rear-facing) without my husband having to sacrifice leg room when he drives. We love the adjustable head rest/shoulder strap feature. The seat includes a cushion for babies 22 pounds and less; however, I wouldn't put very small babies in this seat. The provided padding still leaves lots of room for heads to flop around in. We used an infant car seat until the baby outgrew it.
Pros:
safe, sturdy, easy to use, high quality
Cons:
too roomy for newborns
Best Uses:
convertible car seat, rear-facing, front-facing
