No more awkward lifting and back pain when helping your child in and out of the car seat. The innovative one-hand 360° rotating mechanism provides a comfortable entry and exit position, ensuring less strain on parents' backs.

Because it's the safest way for your little one to travel, the Sirona S i-Size provides comfortable rear-facing travel for children up to 105 cm, approx. 4 years. Keeping your child to rear-facing up to the age of 4 years the Sirona S still offers your child the comfort they need without compromising on safety.

If your infant wants to be forward facing they can from the age of 16 months. The Driving Direction Control (DDC) prevents forward-facing use before the child is at least 16 months old and 76 cm tall so you will know when the time is right.

Sirona S i-Size also offers increased safety for your child 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.

L.S.P system (Linear Side-impact Protection) is on hand to protect your infant in the event of an accident. Increased safety in the forward-facing position now reduces the forces on the neck on a child during a front crash by 20%.

Now even more compact, the car seat includes a 12-position height adjustable headrest with integrated harness guides that grow alongside your infant while the one-hand reclining function provides extra convenience and makes everyday use easier.

A one-click installation with ISOFIX both in rear- and forward-facing position allows for simple installation and guarantees increased safety. Sirona S i-Size is secured using the car's ISOFIX system and requires no further fastening. An installation indicator also helps to prevent a possible misuse.

A one-hand recline function allows you to easily adjust the seat to the perfect position for your little on including 5 rearward facing positions and 3 forward facing recline positions.

The Cybex Sirona S i-Size is one of the most advance car seats on the market and we would highly recommend vising us in store for a demonstration. To learn more on i-size please visit our Guide To i-Size!
