The harness in a child’s car seat helps keep the child safe by spreading the forces of a crash over the strongest parts of their body. As such, a harness that’s set at the right height and tightened properly to a child’s comfort maximizes their safety. Here's a quick checklist to ensure your child's harness is secured correctly when they are rear-facing.


✓ Harness straps at or below the shoulders


✓ Visible slack removed from the hips


✓ Unable to pinch a horizontal fold in the harness straps at the collarbone


✓ Chest clip at armpit level


✓ Buckle tongues locked into buckle
