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.

    I bought this for my daughter in the cow print. I loved it and so did she. So I bought this one for my son. Super comfortable feeling compared to a lot of other car seats. I feel like she's safe and it is super easy to install.

    Comments about Britax Marathon G4.1 Convertible Car Seat with UltimateComfort - Summit:

    Have had the Britax Marathon for about 2-3 years and just had an accident. We were rear ended on 95 at approx 60 mph and my 4.5 yr old is totally fine, not a scratch or ache or anything! I am soo thankful that we had a great car seat. It is also easy to transfer from car to car.

    1st Convertible car seat success!

    By Mommy In Motion

    from Rochester, MN, United States

    Comments about Britax Marathon G4.1 Convertible Car Seat with UltimateComfort - Summit:

    This was our first convertible car seat for our first daughter. We got it for her when she was around 20 months. She needed to stay rear facing for a little longer because she was not 20#s at the time we purchased it. It worked really well and our daughter was very excited and pleased with her new seat! It was so easy to install and to switch back and forth to either of our vehicles when needed. This car seat is everything it said it would be and more! We just recently purchased 2 of the Boulevard seats for both our daughters since we do more traveling now (we moved and have more traveling to do now) and this seat will be our spare for grandparents. A person can't go wrong with a Britax car seat....we never plan to use anything but these seats! Thanks Britax!!! :)

    Comments about Britax Marathon G4.1 Convertible Car Seat with UltimateComfort - Summit:

    This is our 2nd Britax seat for our third child. What an amazing product! Was easy to set up in our vehicle(s) in a variety of different securing situations (Lucas anchors/seatbelt). I was impressed with its construction and the materials used. Our newborn sat safely inside with minimal adjustments (baby is 3 days old at time of writing this). I would recommend this product to any nervous parent who wants the safest product for your dollar.

    Simply the best

    By Aladdin772

    from Orange County, CA, United States

    Comments about Britax Marathon G4.1 Convertible Car Seat with UltimateComfort - Summit:

    I bought 3 different Britax car seats. The Marathon Roundabout, Marathon Click Tight and the Boulevard Click Tight. The Roundabout was the cheaper of the 3 by $90 but was lighter and easier to adjust. I found that the 2 Click a tight models would not loosen all the way, and yesterday my fatherinlaw complained it was too tight for my daughter.

    Secure and Easy Installation

    By thowes

    from Winchester, VA, United States

    Comments about Britax Marathon G4.1 Convertible Car Seat with UltimateComfort - Summit:

    My favorite aspect of this car seat is the ease of installation. Our family spent 2 weeks traveling with no car of our own, which meant we were constantly transferring the children's car seats into different cars. The easy-on/off latch connectors made installation a breeze. I was confident the seat was secure and removing the seat was so much easier than with traditional latches.

    TERRIBLE!!!

    By cmitchell

    Comments about Britax Marathon G4.1 Convertible Car Seat with UltimateComfort - Summit:

    Do not buy this car seat!! My husband and I have been trying to make this car seat work in his new Jeep Grand Cheerokee and our poor son's head hangs down while sleeping. Also while he is sleeping his head bobs around while we are driving. We have tried the pool noodle and towels. So disappointed with the amount of money we spent that it does not work. DO NOT BUY!
