Air Protect Revolutionary Side Impact Technology: Break through system shields head and immediately reduces side impact forces through the precise release of air. Air Protect was engineered to defend your child in two vital ways. During a crash, the system immediately shields your child’s head from impact.  In a second layer of defence Air Protect allows air to escape from the headrest; channelling crash energy away from your child, creating more ride down time.  Maxi Cosi Complete Air seat has been uniquely designed and complies with both 2004 and 2010 manufacturing standards.  Dimensions of the seat: 45(W) x 75(H) x 51(D) cm
