Key Features

It Is Easy to Install:

Anyone who has kids knows how impossible it can be to correctly install a car seat. They are a struggle to buckle in. The car seat can slip or slide. You begin to think that you have it in right, but then you turn a corner and the seat flops over on its side.

It is frustrating.  Your child simply isn’t safe. The Britax Marathon Car Seat has fixed that problem. I love how easy it is install the car seat correctly on the first try. In fact, I can move it  from my car to my husband’s truck in less than five minutes.  Even the size of it is just right to fit your child in comfortably but still be able to switch it to another car if you need too. Uniquely, you could even place a couple of car seats in your backseat, making this a true family friendly item.

Here’s How You Do It:

For a forward-facing car seat, the installation of the Britax ClickTight Car Seat is extremely self-explanatory. The seat part of the car seat, where your child is going to sit, lifts up. You place the car’s safety belt over the back section and snap it into place. It has a guide to show exactly where the safety belt goes. Then you snap the seat back into place.

You will hear it fully engage. The car seat is snug and secure As you can see, you aren’t going to have to struggle to reach around the car seat. You also will not have to try to thread the safety belt through the guiding holes, as in other car seats. This is what takes away the hassle of trying to install a car seat. It makes is extremely nice for grandparents or family that aren’t as familiar with the installation to get the steps right.

Rear-Facing Is Different:

When you are installing the Marathon ClickTight Car Seat in a rear facing position, you need to be a little more aware of the process. One complaint is that the straps get too snug for the child to be comfortable. In order to combat this problem, you need to place the safety strap in the inside guide of the car set. This will enable the straps to be adjusted appropriately without any issues.

The other steps are still the same. You simply lift the seat. Place the car’s safety belt over the car seat and buckle in. Then you just need to place the seat down over the safety strap. The sound of the engaged latch lets you know that you did it right. The way that the seat snaps into place ensures that the safety belt is in the right place. The car seat will fit snug into the seat. Then you place your child into the seat and buckle them in.

Safety Is the Priority

You will be very hard pressed to find a car seat that is any safer than the Britax  ClickTight Car Seat. Simply put, this is a car seat that is made to withstand collision in a way that your child will come out with as few injuries as possible. In fact the safety ratings are higher than you can find on almost any other car seat on the market.  You cannot get anything better than the side impact features on this seat. There are three layers to ensure absorb as much impact as possible. It is highly unlikely that your child’s head is going to be hit on the side of this seat, unlike others that are missing the extra two layers of protection that this car seat provides.

Nice Straps: Besides the side impact protection, you also have the v-shaped straps that are double stitched. The double stitching is to absorb the forward motion so that the car seat forward momentum is absorbed in a way that keeps your child from suffering from whiplash. The straps are wide enough that they are not going to cut into your child if they are pushed forward in an accident.

Shock Absorbing Base: The base of the car seat is specially designed to be a shock absorber. This SafeCell technology is unique to the ClickTight Car Seat. It includes a steel frame that will be less likely to bend or shift upon impact. In short, as a parent you have to understand that accidents happen. You cannot always prevent them, but you can prepare for them. The way that you prepare is too make sure that you have the best possible equipment to prepare for the unknown. This is the car seat for that. The only downside to the safety of this car seat is that it is not set up for Canada safety regulations. You will have to purchase one in Canada in order for it to meet those safety regulations.

We All Want to be Comfortable

Any parent knows that no matter how long your trip is, your child is going to fall asleep. The younger your child is, the more that this is true. You are also aware that if your child isn’t comfortable, the ride is going to be miserable for everyone in the car. The Marathon ClickTight Car Seat has some really neat creature comforts.

My child likes to lay her head on the side because it has great cushioning that doesn’t make her bang her head with every single bump. I like that it is easy to adjust as she grows. That means that your child isn’t going to outgrow it anytime soon. It reclines for the newborn setting, rear facing, so that your baby’s head is fully supported. You can then adjust the reclining position as they grow, making it the only car seat you will need to purchase for them.

It has 14 settings that can be adjusted according to the child’s height. All you need to do is grip the handle on the top of the car seat and pull. You will feel a click at each level so that you can choose the one that you want. You will not have to re-thread it each and every time that you need to adjust it. This makes the  Britax  ClickTight one of the most parent friendly car seats that you are going to be able to find.

You will also notice right away that the car seat is fully padded and cushioned. We have already discussed the really sturdy sides, however, one of the ways that the sides are protected is this cushioning. That means that if your toddlers, or preschooler, falls asleep their head will rest on this cushioning. You won’t be worried about them waking up with a headache because of how their head rested against the side of the car seat.

One concern to be aware of is with the way that the crotch strap buckles in. If not done properly, the strap will cut into your little one’s thighs. The problem is that the crotch strap itself is way too short to enable adjustment. The way that it is fixed is to open the seat, as if you were installing it. There is a dial to loosen the latch strap. You may need to push down on the dial in order to get it to turn.

The warning that comes with this is that if you make it too loose, you jeopardize the safety of the whole system. It needs to be as snug as possible to hold your child in place.


The hard surfaces of the  Britax ClickTight Car Seat are easy to get to and that makes them easy to clean.

The area where the release button is located is recessed. So it catches crumbs in there and you either have to fish around with your finger or vacuum it out.

Although the cover cleans up pretty well just scrubbing it with a wet rag, washing the whole thing requires taking it apart. So if you get to that point, be aware that it will take some fiddling to get the cloth pieces off and back on again.
