SAFECELL SIDE IMPACT PROTECTION
Surrounds your child in a deep protective shell designed to absorb crash forces and shield your child from debris.




IMPACT ABSORBING BASE
Compresses to absorb crash energy and counteract forward movement keeping your child clear from the seat in front of them.




QUICK-ADJUST 10-POSITION HARNESS
Allows you to easily move the harness upward and buckle outward for a comfortable, secure fit as your child grows.




3 RECLINE POSITIONS
Make it easy to find the proper angle for secure installation and your child's comfort.

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.

Top 5 Features:

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

Amazing!
December 3, 2019
I love this carseat. You get the safety with the Britax name but the carseat itself its huge. Fairly lightweigh and very easy to install. I love that the head area doesn't have the bulky side impact portions because our car is more narrow and we have two carseats side by side. Great buy!
Pros
  • More narrow than other models
  • Easy to install
  • Great quality
Best Uses
  • Infant-Toddler (rear and front facing)

Have tried other car seats but this one is definitely our favorite by far! So many nice features but what I appreciate most is that it is one of the less chemically contaminated car seats I can safely put my child in. Have already recommended to friends and family.

Great car seat - straps can get twisted though
April 10, 2019
This is a very safe and sturdy car seat - it also seems to be quite comfortable. The one con is that the straps get twisted frequently which is pretty annoying.

Mostly good
February 28, 2019
I liked the Britax safety and price tag of this seat. Unfortunately and it turns out, not having cup holders is a major issue. My three year old just drop some her cup because she has no where to put it. The Britax cup holder sold separately has many many bad reviews. In addition, there's only 2 crotch strap adjustments. She's starting to complain it hurts. I would say this seat was great from 12 months to 3. But I can foresee us replacing the seat in the future. I'd still recommend the seat. It was a good price, safe, and lasted a couple years.

Baby does not fit
December 27, 2018
I bought it for my newborn because your description states that it can be used since birth. But sadly my baby does not fit at all. Her head drops sideways in a very uncomfy manner and can hardly breathe. Very disappointed with Britax since for obvious reasons I can't use the seat. Also the belts cannot be adjusted right around her legs... I don't really understand why the description states that it can be used for newborns if it is not true.

Perfect for rear facing and forward facing
October 6, 2018
We bought two of these for our oldest child. He rear faced in this car seat for over a year after he outgrew his infant britax carseat and is now forward facing. It has worked great in both positions.

Easy to install and durable
July 26, 2018
My son is 8 and has Down syndrome. He will be small enough for a seat for a long time, and this seat is still working for him. Super easy to install, take in and out if needed, and he can even hook the harness himself because the belts don't twist like other brands.

Fantastic Sturdy Car Seat
June 7, 2018
I am very impressed with the car seat! It is very sturdy, easy to install and is easy to put our six-month-old in and out of. It fits great in our sedan (Chrysler 200). I'm not crazy about the print, but you can't beat the price and the material is well made. Overall, I would purchase it again. Britax & Albee now have a loyal customer.
Pros
  • Easy to install
  • Well made
  • Safe
  • Straps easily move
  • Fits well in sedan
Cons
  • Kind of heavy when putting into the car

Works great
June 7, 2018
I agree with out reviews - please disregard the reviews where people are using the car seat erroneously. The latch system works great in cars with anchors, easy to tighten and they stay tight until physically loosened. Straps adjust perfect for my very large 2 year old. I'm not a fan of chest clips but they are required in the U.S. - no issues with them breaking.

Awesome car seat!
June 4, 2018
This was exactly what I was looking for. Safety is number one and it doesn't get safer than Britax. My baby girl loves it. She is 15 months and 20 pounds rear facing. I have four kids and they all ride in Britax seats.

great car seat!!
May 23, 2018
we have had this car seat for 4 years and have had no issues with it. my daughter is now 4 and fits perfectly. if you follow some of the other pointless reviews of some people misusing the seat then you will be steered in the wrong direction about this seat. for example, you dont buckle you kid in the seat with a winter jacket, the straps are not supposed to be all the way above the shoulders. anyway, the seat is very easy to install using the latch system but the only down fall for us is removing the seat to put in another car. the latch belts dont easily loosen which in my opinion can be a good thing so you dont have to worry about it loosening on its own. cleaning is very simple. it is one of the easiest to take apart. (i have been dealing with car seats for the last 13 years). i just washed it this last weekend. took me all of 60 seconds to strip it down, belts and all. the longest part was waiting for the washer and dryer.

Excellent seat, excellent service
May 2, 2018
This seat is such good quality! All the materials are excellent and the finishing touches make for a great product. I was very pleased with the shipping time, and the price was unbeatable!
Pros
  • Fits well, rear facing, in my sedan, at recline position “3,” for my 1 year old. All the seat Padding is plush, straps don’t twist easily and extra touches like the comfort pad on the buckle keep the straps from pinching baby’s chubby legs. This seat will grow with my child, very well!
Best Uses
  • 9 months, and older, if using in a sedan. Perfect for any age, in a larger vehicle.
Cons
  • Would be a tight squeeze in my sedan, at the recline setting for a smaller infant.

I had a Boulevard for my son. I thought I was purchasing another BLVD until I saw the box at the front door. I considered returning it since I really wanted a blvd. I decided to keep it and it is actually really nice. Easy to install, very comfy looking, and I love the colors!

We are very happy with this car seat. It's always difficult to narrow it down when you have so many factors to consider, including price, but this was a surprisingly easy choice. After a little research this one checked all of the important boxes and Albee Baby offered the lowest price (with free 5-day shipping).
Pros
  • Comfortable, wide size
  • Heavy duty steel frame (this is a GOOD thing)
  • Super adjustable (rear and forward facing option)
  • Our son loves the blue/black colors
  • Incredibly easy to install with the latch system

This specific car seat met all the safety requirements I was looking for in a seat for my one year old. Love how comfortable she is rear faced, also how youre able to adjust the seat easily. The color and pink giraffe print is even better in person!
Pros
  • Safe and secure.
Best Uses
  • Rear facing and reclining features make the car seat safe and comfortable.
Cons
  • Not the lightest car seat but itâ
