I love this seat! We have another brand in my husband's car and it doesn't even come close to this one. Installation is an absolute BREEZE and caring for the seat is super easy. We've washed the cover in our machine MULTIPLE times and it still looks perfect. Let me tell you, my kid has gotten sick on this seat, had accidents in it and eaten ice cream, slushies and all else while sitting in it. It has no stains, no smell and it's in great condition. My daughter has been in this seat since her first birthday (rear-facing and now forward) and it has never let us down. We've taken long trips and she has never complained about being uncomfortable. I recommend this seat to every single parent I know. Now if only I could find the seat cover and cup holder we used to have.....

We love this seat, the latches are really easy to install and remove. I've remove and put the cover back on numerous times for cleaning and it's very simple and easy to do. It's also a great extended rear facing seat my daughter is 2.5 yo and still has plenty of room to continue rear facing. I love the ease of adjusting the shoulder height. This car seat also fits great with other car seats for puzzling them in my backseat.

We've had the car seat about a year now and the only negative thing is the white cording is fraying...other than that it's a wonderful seat.

We love our marathon (except the colour - kiwi). Our daughter has sat very comfortably in it both rear facing and forward facing. The height adjustment is super easy. When we need to move the seat it is lightweight yet durable and the side bar is great for carrying from one vehicle to another. We chose the kiwi colour as it was bright and fun but dirty legs and hands (from dirt and food) quickly stained the seat and easily show. The seat is very sturdy and install is a breeze.

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.

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!!! :)

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.

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.

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.

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!

We purchased our Marathon a little over a month ago. We were extremely impressed with how easy it was to install and how well it fit into our vehicles. We are very impressed with this car seat and we would highly recommend it.

We are delighted with the fit and ease this carseat provides. My daughter was closer to 8 months when we put her in an advocate, so seeing my newborn son in this seat is amusing, but I know I can trust its quality and safety.

I bought this car seat when my son grew out of his infant car seat. I was immediately impressed with the amazing features this seat has, including soft, removable shoulder padding on the straps, as well as rubber buffers that help to keep the chest buckle in place. Even the crotch strap has a padded buffer strap behind it to make it more comfortable. The straps stay in place so well. It is comfortable and stylish.

I bought this about 3 years ago based on reviews and recommendations. It is so worth the investment! It is simple to quickly take in and out of the vehicle when the kids need to ride in other cars. It is quick and easy to adjust the shoulder strap height when I need to use the seat for different sized/aged kids. I don't need to take the seat out and apart to do it. It's also easy to clean! I can take the whole cover off while it is still installed in the vehicle in order to wash it. I LOVE this seat! My two year old son is now using it. The kids are content in the seat and don't complain about discomfort. He calms down from out of the house tantrums when I strap him in and hand him his comfort you. He feels safe when he's secured in his seat.

We have had the marathon carseat for a few years. I love how easy it is to install forward or rear facing, and how sturdy it is. Also, one of the best features is that the straps do not twist or tangle. This has been an issue with other seat we have used. It is also seems very comfortable. Only down fall is that there are no cupholders, which come in handy for older kids, but you can purchase an attachment.

I purchased this a few years ago for the safety features but it is difficult to install. I don't like that you need to put a towel or pool noodle under it to get it to stay at a good level. they should incline more.

I bought this almost two years ago, and I still love it! The straps stay mostly in place for easy latching everytime. The velcro is great to hold straps open for loading.

I received one as a gift and have used it for two kids. Love britax!

We needed a seat for our 4th child since our others had expired. i loved the cute pink and black floral pattern on this seat; I have gotten compliments on it. Cleans up very nicely, too!

I have had the Marathon for 3 years. We have two boys and it keeps them safe in both in the car and in the air. We have used it several times on flights too. Easy installation and easy to get the boys strapped in and ready to go quickly.

Love how well Britax products are made. This seat is so easy to install and with the steel reininforced frame it is very secure. My grandson loves it!

The car seat is very comfortable. It is very easy to use.

Great product and features. Very well made and durable. Lots of styles to choose from to fit your family needs. Worth the price

My son has had this Marathon seat since he was 1 year old. Very easy to install but yet very safe for him. The straps hug him nice and snug. The seat pad comes off for easy cleaning as well.
