Features & Benefits
Superior 360 Degree Protection
- Side Impact Cushion Technology features energy-absorbing cushions on the exterior of the child seat to reduce side impact crash energy by 45%, by diverting crash forces away from your child and providing extra protection for the adjacent passenger.
- True Side Impact Protection distributes crash forces, shields from vehicle intrusion, contains the head and body, and keeps the head, neck and spine “in true” or aligned, to limit injury
- Energy-Absorbing Versa-Tether features a staged-release tether webbing to slow the forward movement, reducing the crash forces reaching the child, and a two-point attachment to minimize forward rotation while anchoring the top of the child seat
- Energy-Absorbing Base deforms in the event of a crash to absorb impact forces
- Energy-Absorbing Foam Liner absorbs and distributes crash forces
- Harness Ultra Guard System (HUGS) provides resistance to forward movement in the event of a crash
- Compatible with SecureGuard which works with the vehicle safety belt in booster mode to prevent the child from sliding under the lap-belt portion of the safety belt during impact, thus minimizing the risk of abdominal injury (accessory sold separately)
