Plush Foam Padding provides premium comfort at every touch point and there are even 7 recline positions with an Automatic Level Indicator so you can adjust to ensure the best installation angle for your vehicle.

The Marathon ClickTight converts from a rear-facing position (for babies 5-40 lbs.) to a forward-facing position (for children 20-65 lbs.) and has been carefully designed to keep your child safe and you free from worry along the way. So click them in, give them a kiss and go with confidence.

I do like this seat, it is sturdy, however a bit difficult to adjust straps due to click tight feature. However, our guy is comfortable and loves it.

I have 19 month old twins that are rear facing. I installed with the seatbelt and it was so easy!It was a breeze to installook! I highly recommend this seat! Only complaint is the straps do seem a little short compared to maxi cosi pria 70. Both my boys love the seat and go right to sleep!

A solid choice
December 21, 2016
Our new Marathon ClickTight convertible car seat is a solid choice. It's pretty easy to install as long as you don't need to take it out. I found the round click tight button that releases the seat very difficult to open once you get it in the car. Also, it was tricky put in my husband's car because of the way the seatbelt kept retracting. One other problem that's somewhat annoying is getting the straps to release, because the button to press is in a hole that you have to put your finger way down into. On the plus side, it has high safety ratings and is a beautiful car seat and very comfortable I believe for our little guy.
ProsHigh safety ratings.
ConsHard to take out once you install.
Best UsesCan fit in a smaller car like a Jetta.

Great car seat for the price. Very sturdy, easy to install, heavy, but not to heavy that it's a hassle to move from car to car. We bought for grandparents car and travel because our foonf was to heavy.

Love this seat
September 8, 2016
We just took the grand daughter on a 700 mile trip in this new seat and she loved it. My Son and Daughter-in-law now wish they had bought this seat. Take time to bring the seat in the house and adjust all the straps for the best fit, in the position the seat will be used (detailed instructions are provided). Then strap your baby in it and have her set in it a bit, to make sure that she is comfortable, before installing it in the car...
ProsVery easy to install and remove from the car and short enough when reclined, to allow the front seat to be moved back to a reasonable distance. Easy to adjust from an upright to a reclined position.
ConsHeavy (has a steel frame), but also has a comfortable carrying handle

Love this car seat
July 2, 2016
We got this car seat to replace our other Britax which was in a car accident. We previously did not have the Click tight model but now that we do, I would say it's definitely worth the extra money. The Cowmooflage is a fun design which is good for both boys and girls. We love this car seat!
ProsFun design Easy to clean fabric covering Click tight design is very easy to install and feels secure.
ConsIt is heavy. Not good for a car seat you have to share between cars.

Easiest secure installation ever!

I love Britax car seats for their safety and harness system but they have perfected the sometimes frustrating installation of the car seat. It is so easy with the click tight. The car seat is heavier than my old one but it has metal bars under the plastic which provides more stability. It is ready for my new grandson's first ride!
By Ashley
Great car seat!
June 9, 2016
I am a big Britax fan always have been and we have 4 kids! This car seat did not disappoint. I absolutely love it! It is sleek and fits great in my van. My son is rear facing and I was surprised by how much room we still have between the back of the driver's seat and the car seat. He seems very comfortable in it and the pattern/material is fantastic. It's breathable and very easy to clean. My only complaint is the click tight was hard for me to click down. I literally had to sit on the seat to get it locked and I had a great deal of trouble unlocking it. Other than that great car seat!

Fits well in our CRV and was easy to install.
By Momof2
March 18, 2016
This product is super easy to install! It is a little difficult in our small suv to install compared to our pick up, but that's any car seat that is rear facing.. It is more the cars fault than anything. Love the click tight feature- makes it way easy to be sure that the seat is nice and snug!! I only wish it was easier to keep the more reclined positions, when in tight spaces. However, my child is safe and I don't have to worry!
ProsWell padded Easy to install
ConsHard to install in cars with smaller seats

Our buddy fits well in his car seat. Installation is a breeze. Harness adjustment is easy. The buckle is a bit hard to unleash, but I get used to it after a while. Cute pattern!

Easiest install ever
February 21, 2016
It installed so quick and barely had any wiggle to it after I clicked it shut. I have a small car, a Kia Rio, and with the recline adjusting feature, I was able to get the marathon installed rear facing behind the driver seat without having to adjust my seat at all.
ProsSturdy Easy to install

good product, easy to install
January 21, 2016
our family has purchased multiple britax car seats but this one is by far the easiest to install. this marathon has a more narrow seat than the previous model, but still has the same weight and height limits. my biggest complaint is how hard it is to get the lower buckle snapped. i spoke with a britax rep and they said they are getting many calls about this issue and plan on making an extender to help fix this issue. if you register you car seat with britax they will mail it to you. i am hoping it comes out soon! this seat is also much heavier than the previous model and the material is nicer/easier to clean.

Best car seat so far
December 23, 2015
Very easy to install with the click tight system, comfy seat, easy to wipe off material. Straps are easy to adjust, no need to rethread straps each time. After going through several lower cost car seats that I absolutely hate, I'm glad I spent the extra this time. It's so worth it! The only con I can find is that it's a little heavy, but manageable.

Returned Marathon G4.1 and bought this clicktight instead. This one has wider space, softer cushion and more reclining positions. Hopefully our baby girl will enjoy her ride when she arrived next month!
