Extended Rear-Facing: Why It Matters

The Science of Safety:

In a frontal collision (70% of serious accidents), forces are distributed differently:

Forward-Facing Child:

• Head thrown forward with extreme force
• Immature neck and spine vulnerable to injury
• Harness must restrain entire body weight
• Higher risk of head and spinal injuries

Rear-Facing Child:

• Impact forces spread across entire back
• Car seat shell protects head, neck, and spine
• Body supported by seat during collision
• Up to 5 times safer in crashes

Why Extended Rear-Facing to 105cm?

• Child's neck not fully developed until age 4-6
• Muscles and ligaments still strengthening
• Head proportionally larger and heavier
• Maximum protection during crucial growth
• International safety experts recommend
• Swedish standard (world's safest) promotes extended rear-facing

Common Concerns Addressed:

• ✅ Legroom: Children comfortable with bent legs
• ✅ Car sickness: No higher risk rear-facing
• ✅ View: Many children prefer rear-facing
• ✅ Developmental: Rear-facing doesn't hinder development

The Sirona T makes extended rear-facing easy with 360° rotation access and multiple recline positions.
