The Britax Advocate 70 G3 convertible car seat accommodates children rear facing from 5 to 40 pounds and forward facing from 20 to 70 pounds. The Advocate 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. Integrated Steel Bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash. Energy Absorbing Versa Tether features a two point attachment and staged release tether webbing to slow the forward movement and reduce the crash forces reaching the child. HUGS Chest Pads with SafeCell Technology are affixed to the seat shell to ensure proper positioning while SafeCells compress to manage energy and provide resistance to the forward movement of your child in a crash.
