The Cybex Sirona S I-Size Car Seat in Manhattan Grey helps parents get little one in and out of the car with no trouble at all – thanks to it’s innovative one-hand 360° rotating mechanism provides a comfortable entry and exit position, ensuring less strain on parents backs. The Sirona S i-Size provides comfortable rear-facing travel for children up to 105 cm, approx 4 years. The Driving Direction Control (DDC) prevents forward-facing use before little one is at least 16 months old and 76 cm tall. Sirona S i-Size also offers increased safety for your baby in the forward-facing position thanks to the Energy Reduction Technology. It is activated as the forces reach their full impact in a head-on collision: The headrest slides down, progressively limiting the neck\'s exposure to the impact forces, and subsequently locks into position. 360 Rotation Mechanism: A clever 360° rotation system makes life easier and less back-breaking for parents. The innovative 360° rotating mechanism of the Sirona S i-Size makes switching between rearward and forward-facing position easy. In addition, it provides a comfortable entry and exit position with less strain on parents’ backs. Rear Facing Car Seat: Safely rear-facing from birth up to approx. 4 years. Significantly reduces the risk of injury in case of a head-on collision. The Sirona S i-Size allows you to transport children rear-facing from birth up to a height of 105 cm (up to 18 kg, approx. 4 years). Depending on your preference, the Sirona S i-Size can also be used as a forward-facing car seat for children (starting from min. 76 cm and 16 months up to 105 cm). Driving Direction Control: The Driving Direction Control (DDC) prevents misuse of the forward-facing position of the car seat. It ensures the forward-facing position is not used before the child is at least 16 months old and 76 cm tall. Energy Reduction Technology: Reduces the strain on the neck in case of a front impact (forward-facing). The Energy Reduction Technology of the Sirona S i-Size offers increased safety for your child in the forward-facing position in the event of a head-on collision. It reduces the forces on the neck of a child during a front crash by approximately 20%, compared to other existing harness systems. Integrated Linear Side-Impact Protection: The integrated L.S.P. System of the Sirona S i-Size offers increased safety in the event of a side-impact collision. It reduces the force of a side impact in combination with the energy absorbing shell by approximately 25%.
