Description



The Britax Marathon 70 convertible car seat is designed for children rear facing from 5 to 40 pounds and forward facing up to 70 pounds. The Marathon 70 achieves revolutionary head safety through the use of patent-pending Britax SafeCell Technology, integrated steel bars, and Versa-Tether that work together to minimize head excursion and reduce the risk of head injury during a frontal impact. The Marathon 70 also incorporates Britax Side Impact Protection, offers a no-rethread, five-point harness, a quick-adjust head restraint, multiple buckle and recline adjustments, and an easy access cover and access to belt paths from the front of the seat. A head and body pillow is provided for comfort and infant positioning.

The Britax Marathon 70 Convertible Car Seat - Allison features:

  • The Britax Marathon 70 convertible car seat is designed for children rear facing from 5 to 40 pounds and forward facing from 1 year and 20 lbs up to 70 pounds.
  • 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.
  • 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.
  • Quick-Adjust Harness repositions the harness shoulder height without disassembling the harness straps.

My husband and I absolutely LOVE this car seat! We used it for 4 months while our daughter was facing the rear, and now that she is 1 year old she is facing forward. While she was facing the rear, the car seat didn't have a good recline. We had to fold up a few towels to place underneath the base because she was leaning too much towards the back of the car. But now that she is facing forward, we have no problem at all with the recline positioning.

We used the car's seat-belt not the anchors while facing it to the rear. It moved slightly, but it still felt pretty sturdy. My husband and I feel much safer having her in the middle seat of the car, which is why we did not use the anchors while facing the rear. Now that she is facing forward, we use the seat-belt and the top anchor. The car seat does not move at all! It feels so much safer now that she can face forward in it.

The only con I have about this car seat is that it is a little bulky. I sat in the back with her during a long trip (while she was facing the rear), and I couldn't fit my arms comfortably by my side. I had to rest them across her legs, but that didn't bother me or her much at all.

Overall, I absolutely love this car seat. I didn't give it 5 stars because we haven't experienced it's full safety during a wreck, but I hope we never find that out. Definitely buy this car seat, I wouldn't waste your money on any other one.

We originally had the 2009 version of this car seat and loved it. Unfortunately we were in a car accident (rear ended and the car seat held up wonderfully) and were told that we had to get a new car seat. So, because we loved the car seat, I ordered this car seat, which is the updated version of the one we had. I don't know if anyone else is experiencing this problem, but the seat belts are not as long as the original car seat we had. Our daughter, who is 20 lbs., fits in it fine, as long as she doesn't have any kind of a jacket on. I don't know what we are going to do when the winter comes, because there isn't much room to maneuver her arms when she has a jacket on. Besides this, the car seat is wonderful. As I said, the first one we had worked perfectly when we were rear ended. The baby wasn't hurt and stayed in place. My only complaint is the length of the seat belt. I did call Britax to see if there was something that we needed to do and they told me to check the back, to make sure that the belt wasn't caught up. We did this and there still is no difference. My suggestion is, if you are able to, check this out in the store and check the seat belts, that they are long enough to pull out to get your babies arms through, where the baby doesn't seem like they are squeezed in the restraints.
Sorry, just remembered something else. The old car seat did not have the new head rest that adjusts as the child gets older. The problem with this is that as the head rest moves up, there is a bit of a gap at the bottom that might be uncomfortable on the baby's back. They do have a cushion that can be used, but if you use it, it covers the velcro side that is supposed to be used to hold the seat belt as you take the baby in and out of the car seat.

    This seat is AMAZING! I use it in both my TINY 4 door Mazda3 and my 2 door Chevy Monte Carlo, and it fits perfectly rear facing in both! It is the easiest carseat I have ever installed! It it safe, comfortable, and stylish! Well worth the money! I wouldn't trust another seat like i trust BRITAX

    Comments about Britax New Marathon 70 Convertible Car Seat - Allison:

    i use this product for my 2 year old girl. We had an envenflo convertible car seat before this but it was in a minor wreck so we replaced with this model. I was looking for a more compact seat that didn't sacrifice comfort or safety. I think britax goes above and beyond the safety requirements and the cover is very cushioned and soft.

    Another thing I like about it is the velcro that helps keep the straps aside when loading your child.

    My daughter was always sliding the chest buckle down while I was driving making her seat unsafe but this car seat has rubber slides that helps keep the buckle in the correct place so she doesn't do that anymore.

    Overall I am very happy with this seat and it's ability to keep my child restrained and comfortable (even while she sleeps).

      Nice Pattern, comfortable, good padding, MADE IN THE USA! It was so nice to find a carseat made in America. I try to buy American whenever I can. I didn't realize it until I bought it and was happily surprised. It is well made, I am supporting our country, and I don't have to worry about any possible toxicity problems coming up in the future.

      Vowed I would not spend this kind of money on this car seat years ago with my first three kids, but after a terrible car accident last year while pregnant with my third, my thoughts changed a bit. So, here I am with a limousine car seat. LOL. This care seat is great with the exception that it is a little challenging to install. I have an SUV and it fits fine, space wise but needs to be anchored in 3 places which can be challenging w/ 4 other ppl in the car. That is the ONLY complaint I have and it is not much of one!

        I bought this for my daughter who just turned one and it's great! It gives her more room and is comfortable. The fabric is comfy too but I worry if she'll get to hot in the summer so I just crank the air on higher back there.

        Overall...we love it!!

          Comments about Britax New Marathon 70 Convertible Car Seat - Allison:

          We were using the 2010 version of the Britax Marathon, which is now the "classic" and we fell in LOVE with Britax! So when the new "70" version came out, we had to have one! We use the other one in daddy's car still :)
          Features i love: the seat rear faces to 40 lbs. which is a HUGE plus, since my daughter is 2.5 and still rear facing. At 32 lbs. i like knowing she still has a ways to go until she reaches the weights limit (if she doesn't outgrow by height first, of course). It also offers more leg room for rear facing! The harness is a lot easier to adjust then the "older" version. It's nice and smooth! I love the way the shell cradles her body, she looks so comfy. Her head never flops forward when she sleeps. The height of the car seat is high enough for her to see out the window. I love the HUGS chest guards, they give you the added benefit of keeping the straps nice and flat on the child's chest. The harness never tangles, huge plus...if you've had one that does twist, you'll know what i mean!! The no-thread harness adjuster is brilliant! I also love the little velcro on the sides of the seat, it helps the straps stay open when you put your child in the car. It also keeps the crotch buckles from falling down to the bottom of the seat, which would require you to dig for them (like i have with other brands!). It installs pretty upright, at least in my car. So if you're using it for a newborn, you'll most likely need a noodle. Acually, i purchased a noodle and use it just to give her a little extra leg room and so she's not so cramped. As long as it's within the degrees allowed by Britax, it's fine. I've bought (and returned) numerous other brands and once i found Britax i new i had a keeper. Not to mention i did extensive reseach!
          Let's see...the only con i can think of is the lock offs are a pain in the butt! We don't have latch, so we have to use the vehicle seat belt. Luckily we can get a rock solid install without the lock-offs. It's a little heavy, but i honestly don't notice it, i'm used to the other Marathon, and honestly, i like knowing that it is well made and not some flimsy plastic. So i don't really consider that a con. Other than that, it's perfect, i recommend it! I also recommend rear facing beyond a year. Do some "youtube" searches for "extended rear facing" and watch the videos, that's what made me think twice about turning my daughter forward!

          Our daughter was 7 months old when we bought this, but she's now 8 months. She seems much more comfortable in this convertible car seat than her infant car seat. She isn't as cramped, and seems relaxed while sitting in it. We haven't used it in the car yet, because we have to scoot our seats up so it will fit. We're considering installing it now though, because she looks so uncomfortable in her infant car seat. We'll have no problem with the space issue once she turns 1 and we can install it facing forward.[...]I just opened the box, and it was already assembled. I also love the print of it, and the fabric is so soft! Our daughter can't stop rubbing it while she's in it.

          This is one of the safest carseats... It is bulky but I know our daughter is safe in it... We had the Chicco travel system which we love, and now we will begin to use this seat in the summer... She has sat in it in our home and she loved it... Well padded...
