Packed with comfort and safety features, the Britax Marathon G4 convertible car seat is constructed to provide head safety through the use of Britax SafeCell Technology in the base, integrated steel bars, and energy absorbing Versa-Tether that work together to minimize head excursion and reduce the risk of head injury during a frontal impact. It offers a no-rethread and quick-adjust five-point harness and EZ-Buckle system for convenience when harnessing your child, and an easy-remove cover for quick clean-ups that also allows access to the belt paths from the front of the seat. The Marathon accommodates children rear facing from 5 to 40 pounds and forward facing from 20 to 65 pounds.
Head Safety Technologies for Advanced Protection
The base of the Marathon includes SafeCell Technology comprised of SafeCells, an engineered material designed to compress in a crash. This compression lowers the center of gravity to counteract forward rotation of the seat, helping to minimize the risk of head injury during a collision. Located in the sides of the seat shell, integrated steel bars strengthen the connection to the vehicle and prevent forward flexing of the seat during a crash to reduce the risk of head injury.In the event of a sudden stop, the Energy-Absorbing Versa-Tether strap restricts forward movement and reduces crash forces with patented staged-release webbing and a two-point attachment. This webbing securely anchors the top of your child seat to your vehicle in either rear- or forward-facing positions.
No-Rethread Harness System and Comfort Features
The tangle-free, five-point harness allows for multiple height positions and can be adjusted without dismantling the harness or removing the car seat from the vehicle. Two buckle positions provide a snug, comfortable fit as your child grows. The seat’s harness holders prevent the straps from getting in the way when you’re putting your child in the seat, while the EZ-Buckle system maintains the harness buckle in a forward position to prevent your child from sitting on it when first entering the seat. Rear- and forward-facing recline options, as well as high-density foam cushioning, help your child relax on the journey. And the plush cover comes with matching comfort pads and an infant positioning pillow to keep children of all ages comfortable and secure. Product Information: The Britax Marathon is assembled in the USA and has a seven-year life. What’s in the Box: Britax Marathon Convertible Car Seat, removable cover, comfort pads, infant positioning pillow, and user guide.
