The Britax Marathon convertible car seat is designed for children rear facing from 5 to 40 pounds and forward facing from 20 up to 65 pounds. The marathon achieves revolutionary 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. The Marathon also incorporates Britax side impact protection, offers a no rethread and quick adjust five point harness, multiple buckle and recline adjustments, and an easy remove cover that also allows access to belt paths from the front of the seat. A head and infant pillow is provided for extra comfort and infant positioning.
