I bought this car seat in March of 2021 and after 1 year and 2 months of use I noticed that the hip belt strap is fraying on both sides. One side is hanging on by a thread. Clearly this started during the 1 year warranty period but Britax will not replace the harness under warranty. This is so bad I cannot use the car seat at all and this car seat is supposed to last 10 years????

[This review was collected as part of a promotion.] Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat. We really like this car seat. The install is my favorite part about it! It’s so easy to click in and so secure! It doesn’t budge at all, putting my mind at peace. The look and feel of the car seat is so slick and nice. It’s easy to clean, wipe off and maintain. I don’t know if it’s because it’s so new and stiff still, but it is hard to adjust the safety straps and get them tight enough. Also the strap tension release button is a little too far inset, especially for my husband who has bigger fingers. We’re hoping as we use it more the straps will get more “broke in” and easier to adjust. Overall a great quality, safe car seat and very happy with it. Just hoping it gets easier to adjust as time goes on.

[This review was collected as part of a promotion.] When I received my car seat I loved that it came in an easily accessible box. I didn’t have to break the box or lift the car seat to get it out. I loved the back and grey color scheme that I received. The material is soft and the cushion is comfortable for my 3.5 year old. After reviewing the manual and a quick video on YouTube I was able to figure out how to install the car seat. It was a lot simpler than I thought. Pull out the latch belt, Twist the click tight button to lift the compartment, thread it through, buckle and tighten. My only drawback when installing was you have to be careful not to pull it too taut that it’s creates tension to the point that you can’t close the click right compartment. Once it’s closed the car seat was super secure. It didn’t move at all. My son sat in his new car seat and was pleased with how comfortable it was. He was very excited to be in a new seat. He buckles himself in and I tighten the seatbelt every time. It was easy for him to buckle without me having to intervene. I am not a fan of the impact absorbing chest pads although I do appreciate them. I just feel like they are in the way and I have to adjust them every time he gets into his seat. I can’t vouch for the cool flow and dual comfort fabrics as I live in the northeast and have not experience the heat yet but hopefully it’ll come on handy in the summer. For now, it’ll stay in my vehicle as our permanent Car seat. I was gifted this convertible Car seat to try as a part of the Stellar product Testing Panel

[This review was collected as part of a promotion.] I received the car seat as part of the Stellar Product Testing Panel, however I am writing this review with the same honesty as if I had bought it myself. In short, this is a solid, safe car seat that is a breeze to install even for car seat newbies. Pros: +The Clicktight system is super easy to use when installing the seat, so it can get transferred from car to car without taking much time. I wish I had known about this earlier and would have bought this seat from the very beginning. +It is comfy. My toddler is still rear-facing and used to an extender to give his long legs some space. I was worried that he would feel too squished but he said that he is very comfortable. +You can take off all the padding in pieces and without uninstalling the car seat. If your kid gets carsick, spills a lot, or just seems to attract messes then you know how important this is. Easy off, no class in car seat construction required. +My kid loves it. He genuinely likes climbing in and he has told his preschool teachers and classmates all about his car seat. He falls right asleep on longer car rides. +Easy to adjust the size. As he grows or someone else needs the seat, it is easy to adjust the straps back and forth. Cons: - It is big. This might not be an issue for your car, but this is not a seat for doing three across. We only have two, so it is fine for us. -Adjusting the chest clip is awkward. There are rubbed pads below the shoulder pads, on either side of the chest clip called Impact Absorbing Chest Pads. They tend to stick to clothes, so if you need to adjust the height of the chest clip, it takes more effort. I like the safety feature but would prefer something less grippy. -Harness straps don't stay even. I have had to reset the straps more often than other car seats. I make sure my kid is sitting in the middle of the seat every time, but it still happens. This is why I would give it 4 stars instead of 5.

[This review was collected as part of a promotion.] This car seat is most importantly safe and secure. The click tight feature not only keeps the car seat tight, but makes it extremely easy to move from car to car, which we actually do a lot with babysitters and grandparents, so that was very important to us. The fabric is also very soft and comfortable for our kids and easy to clean, again SUPER important. I think the seat is very sleek looking as well and looks high end. The fabric we have is also cool in the heat of a South Carolina summer, which the kids and parents very much appreciate! Overall a great car seat that can grow with your child from newborn to toddler. We do have a 4.5 year old that is 52lbs and 46" and it is a little too small for him, so if you are looking for an older child this probably isn't the best fit. Overall, this is a fantastic seat with lots of great features that both parents and children can appreciate! Thanks to the Stellar Product Testing Panel for providing me with this convertible car seat.

[This review was collected as part of a promotion.] Very impressed from the get go with this seat. It’s packaged well and feels substantial even in the box. Once we took it out, it’s a great looking seat. My boys all liked the feel of the fabric, and I love knowing that it’s not full of chemicals. The straps are cool, they have like a rubbery bumper thing on the back so they stay in place. Installing the seat wasn’t too bad, it’s a pretty big seat though so I wouldn’t necessarily want to be getting it in and out all the time. The Click Tight technology is neat (and reassuring to know it’s been installed correctly) and Britax is known for safety and performance…and based on the construction of this seat, you can tell. One of our favorite features was how customizable the position/recline was, which is great if you have fussy car riders like I do that are all different ages. There’s some nice plush padding too, which helps with the seat being comfy. We’ll see how it is in the summer though, all that may lead to a hot seat in the heat. I was given this convertible car seat to try as part of the Stellar Product Testing Panel.

[This review was collected as part of a promotion.] Let me start off by letting you know that we currently own 6 Graco 4ever car seats. We have 3 children under 5 and utilize 3 car seats for each vehicle. I was over the moon to try another brand of car seat to see how they compare. When I unboxed the Britax Marathon ClickTight I was immediately impressed by the aesthetic of the car seat. The material is so soft, durable and looks high quality! I am in love with the gray and tan color scheme and love how chic it looks. I have a difficult time installing and tightening our Graco car seats so I was pleased at how easy I was able to install this one. I didn't spend 30 minutes in the car frustrated and giving up and finally have my husband take over. I love that I can easily take this out and put in a grandparents car if needed without stressing that it is not installed correctly. The car seat is very roomy and my 18 month fits comfortably in the rear-facing position. The straps are easy to tighten and loosen, which is important when you have to take them in and out of the car multiple times a day. One part I didn't love was the rubber tracks next to the chest buckle, but that is just a minor complaint in comparison to all the positives. The material is so nice and looks like it can easily be removed from the base in case you need to wash it. The most important thing is that it is SAFE for your children. This car seat has a steal frame and full body side impact protection that surrounds their head, neck, and torso. I'm excited that this will grow with my child which is important to me when purchasing a car seat. A few minor things to consider - I wasn't able to adjust the position of the seat once I had it strapped in and tightened and it does not have any cup holders. So far I am really liking this car seat just as much as our current Graco's and this one is priced more affordably. Thank you to the Stellar Product Testing Panel for sending this convertible car seat to me and allowing me to try it out!!

[This review was collected as part of a promotion.] I used to say that all car seats are the same, but this one has changed my mind and stands above the rest! The main feature here is the click in design, and it did not disappoint. I think anyone who watches the video on how to install it could do it easily and quickly. But if you’re getting this car seat because you think it will be so easy to switch from car to car, you need to know that it is seriously heavy. Could your husband carry it around? Yes. Could your mother in law carry it around? I don’t know. But once it’s clicked in it feels incredibly secure- the most important part of a car seat! Plus the cushion is so nice! It feels more like a memory foam than anything else, and even the bottom buckle area is cushioned so it’s not pressing uncomfortably into the crotch area. My toddler used to get car sick all the time when he was rear facing and getting the car seat clean was a nightmare. Being able to easily take off AND easily put back on the cushions is a major perk with this seat (I didn’t wash it yet but I did practice taking it off and on). I do wish that it had cup holders but that’s what snack cups are for. Thanks to the Stellar Product Testing Panel for providing us with this car seat. We are so happy with it and will be filling it with goldfish crumbs for years to come!
