The Britax Marathon 70-G3 convertible car seat accommodates children rear facing from 5 to 40 pounds and forward facing from 20 up to 70 pounds. The Marathon 70-G3 is purposefully designed and engineered to minimize the forward movement of your child's head during a frontal impact to reduce the risk of head injury with the following revolutionary Britax head safety technologies: base with safecell technology designed to compress in a crash, significantly lowering the center of gravity and counteracting the forward rotation of the child seat. |
