Integrated steel bars strengthen the connection to the vehicle and reduce forward flexing of the child seat during a crash
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
Side impact protection comprised of deep side walls lined with energy-absorbing EPP foam distributes crash forces, shields from vehicle intrusion, and contains the head, neck and body
Tangle-free; Five-point harness distributes crash forces across the strongest parts of the body and provides a secure fit
