Britax Marathon ClickTight Convertible Car Seat

The Marathon ClickTight Convertible Car Seat is an excellent choice for getting your family where they need to go safely, comfortably and with so much ease. With the ClickTight Installation System, now everyone can install the car seat securely and confidently by just buckling the seat belt. You simply open the front of the car seat, buckle the seat belt across the belt path and then click the seat shut for a proper installation every time. SafeCell Impact Protection surrounds your child in safety components that work together to protect well beyond the established federal safety standards. And Complete Side Impact Protection shields your little one in a deep protective shell designed to absorb crash forces and protect from debris.

A car seat works best when it provides the right fit so the Marathon ClickTight comes with the Quick-Adjust, 12-Postion Harness and 2-Position Buckle to keep up with your growing child. Plush Foam Padding provides premium comfort at every touch point and there are even 7 recline positions with an Automatic Level Indicator so you can adjust to ensure the best installation angle for your vehicle.

The Marathon ClickTight converts from a rear-facing position (for babies 5-40 lbs.) to a forward-facing position (for children 20-65 lbs.) and has been carefully designed to keep your child safe and you free from worry along the way. So click them in, give them a kiss and go with confidence.
