    A Chemical-Free Choice

  • The Knox Convertible Car Seat is equipped with Koroyd® technology integrated into the base to create an effective crumple zone protecting the child from impact forces

    The Ultimate Damage Control System

    Koroyd® was developed from aerospace safety research and is now built into the base of the Knox car seat, providing more advanced impact protection. The welded tubes crumple instantly and consistently on impact, absorbing maximum force in a controlled manner, minimizing energy transferred to the child.
