This harness-2-booster seat grows with your child from toddler to big kid. With our patented ClickTight Installation, you’ll know it’s right in 3 easy steps. 2 layers of side impact protection surround the head, neck & torso. Plus, SafeCell Impact Technology creates a crumple zone that absorbs crash energy.


  • 2 layers of side protection formed by a deep foam-lined shell and quick-adjust head protection.
  • 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 slow your child’s forward movement during a crash.
  • Compatible with SecureGuard Clip (sold separately) to keep proper seatbelt alignment over hips and prevent children from sliding under the seatbelt in booster mode.


  • ClickTight Installation System makes safe installation as simple as buckling a seat belt.
  • Easy-on/off lower anchors for an alternative installation method.


  • Hassle-free transition from harness to booster mode by tucking away straps in the seat.
  • 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.
  • Cup holders and storage for drinks, food and toys.


  • No-rethread 9-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.
  • Multiple-position recline allows your child to relax in comfort.
  • Plush memory foam padding for premium comfort.
