Product Description

The BRITAX MARATHON™ convertible car seat is designed for children rear facing from 5 to 40 pounds and forward facing from 20 up to 65 pounds. The MARATHON achieves revolutionary head safety through the use of BRITAX SafeCell Technology® in the base, integrated steel bars, and energy absorbing Versa-Tether® that work together to minimize head excursion and reduce the risk of head injury during a frontal impact. The MARATHON also incorporates BRITAX Side Impact Protection, offers a no-rethread and quick-adjust five-point harness, multiple buckle and recline adjustments, and an easy-remove cover that also allows access to belt paths from the front of the seat. A head and body pillow is provided for extra comfort and infant positioning.

The Britax Marathon G4 Convertible Car Seat Features:

  • Base with SafeCell Technology®
  • Energy Absorbing Versa-Tether®
  • Side Impact Protection
  • Harness Ultra Guard System (HUGS™


Britax has been a pioneer in child passenger safety for more than 35 years, with a legacy of leadership in developing innovations that enhance the safety of child car seats and improve their ease of installation and use. Their uncompromising focus has made Britax the best-selling child seat in Europe and one of the brands most trusted by American parents and caregivers since entering the U.S. market in 1996.

Features

  • Base with SafeCell Technology® features SafeCells designed to compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat which normally propels the child toward the front seat
  • Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash
  • Energy Absorbing Versa-Tether® features a staged-release tether webbing to slow the forward movement, reducing the crash forces reaching the child, and a two-point attachment to minimize forward rotation while anchoring the top of the child seat
  • Side Impact Protection comprised of deep side walls lined with energy-absorbing EPP foam distributes crash forces, shields from vehicle intrusion, and contains the head, neck and body
  • Harness Ultra Guard System (HUGS™ provides resistance to forward movement in the event of a crash

I was recently in a front-end car accident in which the car (2006 Honda Civic) was totaled. My son (4 years old, 44 lbs.) was front-facing in the Marathon CS and sustained no injuries at all. He was up running around after the accident and complained of no pain in the days following. He only had minor seatbelt burn near his neck. It has been a week, and I am still in bed suffering from severe muscle spams and pain/whiplash. I am very pleased with this car seat and how it protected my son in the wreck. It is also very easy to install, easy to remove the covers to wash, fairly light weight. I highly recommend this seat. My son has used it since he outgrew the infant seat around age 1.

I've had these for over a year. After a couple washes the cover fell apart; the seems came undone and the edges all frayed. My girls are tall for their age and I got these because they said they would accommodate 49 inches. Kate is 42 inches and with the seat back all the way up the straps are just slightly above her shoulders. She will never make it to 49 inches and meet the "at or above the shoulder" requirements. When we installed these rear facing we had to put towels under them to meet the proper alignment, we have a Sienna so I'm not sure if that is a problem with our vehicle. Under the seat cover is a half inch thick layer of foam and that is all there is for comfort; that also breaks apart if you have to wash it. I did a lot of research and this is supposed to be a good product. If this is good I'd hate to see the bad. There is a sturdy looking bar along the sides that look like it would give pretty good protection; this perceived protection is why I'm giving it a 2 and not lower. The rest of the impact protection is just compressed Styrofoam. Those flaps on the head rest that look like they might surround the child's head are just for show and don't actually fold to cushion her head when she falls asleep. Every single time I put the girls in them I have to raise the chest buckle, adjust the shoulder pads, and untwist the straps. The Velcro to hold the straps to the edge is a nice concept but it doesn't line up and is worthless.

Favorite carseat

By Meghann

from Charlottesville, VA, United States

Comments about Britax Marathon G4 Convertible Car Seat - Kiwi:

We have been using two Britax Roundabout carseats since our oldest daughter was born in 2009. Sadly, after two more children, those seats have expired. With our fourth child on the way the decision to replace the expired seats with another Britax was easy. After a lot of research I chose to purchase the Marathon as opposed to the Roundabout this time. I'm so glad I did. I thought my Roundabout was easy to use. The Marathon was SO simple to install, takes up even less space in the car, and is much more comfortable for our 2 1/2 year old son. I can easily adjust the straps to accommodate my four and six year old daughters as well. They are all fighting to sit in this new carseat. I only wish I could have purchased two more! I can not say enough good things about this seat. If you are hesitating about purchasing this carseat, don't. It's well worth the money, and will last you for many years to come.

Comments about Britax Marathon G4 Convertible Car Seat - Kiwi:

We just used it for the first time the other day, for an infant 12 lbs. It was so easy to install and put him in, and get him out. For us older moms and dads starting over again, Thank you for the help.

Disappointed

By akoz13

from Grand Rapids, MI, United States

Comments about Britax Marathon G4 Convertible Car Seat - Kiwi:

I have one complaint. The durability of the cover. One of the things we looked for when purchasing a car seat was the ability to take the cover off to wash it. We've had the car seat for about 2 years and have washed the cover (as instructed) maybe 3 times. The seat is fraying and coming apart near the head and down by the legs. It looks horrible. It's very disappointing considering the cost of the car seat. We are outside the warranty so we can't return it. We purchased a Safety 1st car seat for my husbands car and the covering has held up way better. Maybe I got a fluke cover but it's time for a convertible for our second now and unfortunately I won't be spending the money on a Britax again.

Comfortable ,safe ride

By Tanya86

from Woonsocket, RI, United States

Comments about Britax Marathon G4 Convertible Car Seat - Kiwi:

I bought this seat about 3 months ago, and we love it. My daughter is much more comfortable in it than she was on the bucket seat. The roll bars make me feel like she is extra safe. Relatively easy to install , still in rear facing for a while. Very happy with this purchase.

Great features, easy to clean, comfortable

By Jacqueline

Comments about Britax Marathon G4 Convertible Car Seat - Kiwi:

I've been been very pleased with both of my britax carseats. However, one of the covers was not wearing very well so I called customer service to see if I could order a replacement. They took my information and said "okay, that will ship out tomorrow and arrive in 2-5 business days." No charge. Just like that! I could not be more pleased!

Wish I bought another car seat

By Mushy

from Los Angeles, CA, United States

Comments about Britax Marathon G4 Convertible Car Seat - Kiwi:

I bought this car seat just before my child's first birthday and have only had it for 16 months. When I went to put my child in her car seat this morning, I noticed that the blue rear facing lock off was up in the air. It turns out it had cracked and popped up and is now totally unusable. The clamp was always difficult to use, but in my car it was the only option to put my child rear facing in the middle seat. I am really disappointed because now I need to go get a new car seat. This car seat should not be advertised to grow with your child when it's poorly made. For further clarification, the car seat has only left the car about 5 times in the last 16 months so its not as if the clamp was even getting open and closed that much. I will refrain from ever purchasing another Britax car seat product. I honestly do not understand why this car seat gets such glowing reviews unless people who are having problems aren't reviewing the product.

By arsees2324

Comments about Britax Marathon G4 Convertible Car Seat - Kiwi:

We love this car seat and wish we had two, one for both cars as we have another brand of seat in our other vehicle. The seat is very heavy! We have to take our seats in and out often and it is heavy, however it is easy to install and my son is always comfortable. The cover comes off nice and is easy to wash. Great carseat!
