This item is a final sale item. Returns cannot be accepted.

The Marathon is a high-performing seat with an adjustable fit, making it a solid choice for your child from the #1 brand in safety technology. Safeguards your child with side impact protection, an impact-absorbing base and steel frame. Safely installs with easy-on/off lower anchors. Easily adjusts with the push of a button – no need to rethread the harness. Includes car seat and removable pillow.

Product Features:

  • Impact-absorbing base compresses to reduce the rough force of a collision.
  • Impact-stabilizing steel frame offers superior strength where you need it most: at the connection point to the vehicle.
  • V-shaped tether minimizes seat rotation with a unique two-strap design.
  • Britax-patented staged-release stitches slow the seat’s forward movement during a crash.
  • Impact-absorbing harness pads adsorb energy and reduce your child’s forward movement during an impact.
  • Proudly engineered, tested and made in the USA with global components for top safety and quality.

  • Easy-buckle system keeps buckles and straps out of your way when positioning your child.
  • Easy-remove cover pulls free of the car seat for cleaning without having to remove the harness.

  • On/off lower anchors lock into place with a click and easily release with a push of a button.
  • 3-position recline makes for easy angle adjustment.


  • No-rethread 10-position harness quickly adjusts with the push of a button as your child grows.
  • Quick-adjust 2-position buckle easily moves outward as your child gets bigger.
  • Removable body pillow adds comfort and can be removed when your child outgrows it.
