Britax Marathon Convertible Car Seat Granite Britax International has been manufacturing innovative, industry-leading child products for over three decades. Their dedication to safety, comfort, and convenience is certainly apparent in this convertible car seat. Its ample attributes—both for parents and baby—and amazing attention to safety standards, make the Marathon a true front runner.
Safety first is a good rule of thumb, and one that Britax certainly heeds. The Marathon offers features you might find on many other car seats, such as convertibility, a five-point harness, and the LATCH system. But Britax enhanced and then went above and beyond the norm when creating the Marathon.
Their five-point harness system is made with strong polyester webbing, fits snugly over baby’s shoulders, collarbone and hips to provide a secure fit, and the straps are designed to remain tangle free. There are also four adjustable height positions so the seat grows with baby. A patented “floating” HUGS™ (Harness Ultra Guard) system better distributes the webbing loads, reducing head movement and minimizing harness irritation on baby’s neck in case of an impact. HUGS also reduces the chance of improperly positioning the chest clip.
Located near a vehicle’s seatbelts, factory installed anchor points provide a secure and easy LATCH connection. In conjunction with this push-button release system, the Marathon also offers Britax’s Versa-Tether , an anchor aid that provides additional security in the forward facing position for children weighing more than 50 lbs. The Versa-Tether fastens the top of the car seat to factory installed automobile anchor points, minimizing the possibility of a head injury.
Need more? The Marathon provides built-in lock-off clips that keep the seat tightly in place when using only traditional seatbelts at installation. A simple handle pull allows the car seat base to be easily reclined when rear-facing. A smooth ride is guaranteed for baby through the comfy padding and soft fabric cover, which is stain resistant, removable, and washable. The Marathon is Federal Motor Vehicle Safety Standard (FMVSS) 213 compliant, making it approved for airplane use as well.
It should be noted that the Marathon is larger (28″H x 19.5″W x 25″D) than most car seats, and can be a tricky fit, especially in the rear facing position in a smaller car. Allow for 31″ of backseat space to properly accommodate this model. With its bigger size this car seat is also heavier than many. Completely empty the Marathon weighs nearly 18 pounds. But these same features are what allow the car seat to have a higher weight capacity and therefore last well into childhood.
Since car seats are mandated by law, it’s nice to know that Britax is at least making the choice simple for you. The Marathon is easy to install, super comfortable for baby, available in a wide range of colors and patterns, and, most importantly, safe!
Comparing Britax Car Seats
If you’re debating between the Britax Marathon and the Britax Roundabout, think of the latter as the little sibling. They are identical in comfort and convenience features, but the Marathon has a higher weight maximum, and is therefore larger than the Roundabout.
The Britax Decathlon is also similar to the Marathon, but offers two features you might need. First, the Decathlon offers additional padding for newborns with an infant positioning system, giving more peace of mind to first time parents. Second, the Decathlon offers an adjustable three-position crotch strap, which makes the seat more comfortable for toddlers consistently at the top of their height percentage.
This car seat is great. I would highly recommend it to anyone looking for a safe, comfy, and easy-to-use seat for their child. I’l happy that the weight range is so wide; I can use if for years to come!
