About the NEW 2016 Improved Britax Marathon ClickTight Convertible Car Seat

NOTE: This is the POST-RECALL improved version of the ClickTight Marathon car seat - the harness adjustor button has been fixed! Read more about the recall here.



Moms drive a LOT. On average, men drive more (16,500 miles a year), and women less (10,100), but moms add a lot of extra miles. From infancy through childhood and up through high school, you’ve got pediatricians' appointments, baby classes, sports, activities, and so on, up until suddenly you find yourself waving goodbye as your kid embarks for college. (It all goes by so fast!)


For all those marathon hours of driving you'll be putting in, you want a car seat that provides quality protection for the long haul: the Britax ClickTight Marathon Convertible Car Seat! Along with superior safety technology, this car seat features Britax's revolutionary ClickTight system, which ensures a simple, tight installation in three easy steps:



  1. Open the window in the front of the car seat;
  2. Thread the belt through the belt paths;
  3. Click the compartment closed. That’s it!



Only a correctly installed car seat will provide full protection for your child on the go, and ClickTight makes it easy!


As with all Britax car seats, the Britax ClickTight Marathon Convertible Car Seat also features an array of technologically advanced safety features to keep kids safe when accidents happen, including:


  • SafeCell Impact Protection: An integrated system of safety components that works together to provide optimal protection, far beyond what is required by federal safety standards. The system includes an Impact Absorbing Base, Tether, and Harness, an Impact Stabilizing Steel Frame, and Complete Side Impact Protection.
  • SafeCell Complete SIP: This system surrounds your baby in a deep protective shell that absorbs crash forces and shields children from debris.
  • 7-position recline: This allows you to adjust the car seat’s recline perfectly to fit a wide range of vehicle seats, and for your child’s comfort.
  • Easy to adjust harness: The 12-position harness and 2-position buckle make it easy to adjust for the correct fit for comfort and safety.
  • And more: Plush foam padding in the cover, buckle pad, shoulder pads, and removable pillow; the EZ-Buckle System to keep buckles and straps out of the way while loading your child into her car seat; an easy-remove cover for easy cleaning; and more!



The Britax ClickTight Marathon Convertible Car Seat is airline certified, so it can protect your child on a plane as well.


Use the Britax ClickTight Marathon Convertible Car Seat rear-facing with your baby from 5-40 pounds (children should ride rear-facing for as long as possible), forward-facing from 20-65 pounds.

Baby stays safe and comfortable


Easy to install, easy to adjus harnesst, baby is comfortable, fits well in car


difficult to adjust position once installed

I was able to quickly install this in my Nissan Versa hatchback (rear facing using the LATCH system). My 9 month old was comfortable enough to fall asleep on the ride home. The car seat wins on both ease of installation and comfortable for baby. The harness is also very easy to adjust. I appreciate that these seats were clearly called out for being made post-recall. I did double check the manufacture date and everything checked out. We just purchased a second one for our other car.

Yes, I would recommend this to a friend.
