SafeCell Impact Protection: Superior Protection, Only from Britax

Britax is the only child car seat brand that features world-class SafeCell Impact Protection. This integrated system of safety components provides unmatched protection for your child. These features include a steel frame, energy-absorbing base, V-shaped tether to minimize seat rotation and staged-release stitches that slow and reduce forward movement during a crash.

Side Impact Protection

Side impacts represent 25 percent of collisions. In fact, it’s these accidents that result in the most severe injuries. We designed the Marathon with these statistics in mind. The seat has a deep foam-lined shell to absorb energy and shield your child from side impacts.
