UPPAbaby Knox Convertible Car Seat Safety Features

  • Koroyd® technology - welded tubes crumble in a collision to absorb the force and minimize the energy transferred to the child. 
  • Side Impact Pods located on the side of the car seat's shell absorb crash force in a side impact crash.  
  • EPP foam located strategically between the inner and outer shell absorbs collision forces.
  • Multi-Directional Tether - this unique tether reduces car seat rotation in a collision which decreases stress on the head and neck.  In rear-facing mode, the tether has been shown to reduce potential injury by 45%.
