The Britax Marathon ClickTight Convertible Car Seat features the ClickTight Installation System, making installation as easy as buckling a seatbelt. SafeCell Impact Protection surrounds your little one in safety, and Side Impact Protection, formed by a deep energy-absorbing shell, shields your child from the most severe type of collision.

 

Specifications
  • ClickTight Installation System is safe and simple to use. Open the front of the car seat, feed the seatbelt through the indicated path, buckle and click the seat shut.
  • Side Impact Protection, formed by a deep energy-absorbing shell, shields your child from the most severe type of collision.
  • SafeCell Impact Protection with a steel frame, energy-absorbing base, and patented V-shaped tether.
  • Impact-absorbing base compresses to reduce the force of a collision.
  • Impact-stabilizing steel frame offers superior strength where you need it most: at the connection point to the vehicle.
  • Patented V-shaped tether minimizes seat rotation with a unique two-strap design.
  • Staged-release stitches slow and reduce forward movement during a crash.
  • Click & Safe Snug Harness Indicator gives an audible “click” to aid you in the proper tightening of your child’s harness.
  • Quick-adjust 12-position harness and 2-position buckle allow you to easily move the harness upward and buckle outward for a comfortable, secure fit as your child grows.
  • 7-position recline with automatic level indicator adjusts for proper fit. 
  • Plush foam padding and fabrics for premium comfort.
  • Easy-buckle system keeps buckles and straps out of your way when positioning your child.
  • Easy-remove cover for cleaning without having to uninstall the car seat or remove the harness.
  • Suitable for children 5-65 lbs.
  • 1-Year Limited Warranty.
