Product Highlights

Peace of Mind With The Safest And Easiest Installation

Typically up to 75 percent of car seats are installed incorrectly, but our revolutionary ClickTight Installation System is the safest and easiest technology on the market. Just open the front of the car seat, buckle the seat belt across and click the seat shut. That’s all you need to do for rock-solid installation – the seat won’t budge and you can travel worry-free with your child.

Safecell Impact Protection: The Best 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 ClickTight with these statistics in mind. The seat has a deep  foam-lined shell to absorb energy and shield your child from side impacts.

Maximum Fit and Comfort

We developed the Marathon ClickTight to safely and comfortably hold your child from birth all the way through the preschool years. The easy-adjust harness grows along with your child with 12 different positions. Change the height of the seat with just the push of a button – no inconvenient rethreading necessary.
