CYBEX Sirona Z i-Size Plus Car Seat - Midnight Blue

CYBEX Sirona Z i-Size Plus Car Seat - Midnight Blue offers all the benefits of the Sirona Z i-Size plus luxurious, denim-look fabrics. Tested to UN R129 standards, this rearward and forward facing i-Size Car Seat has a 360 swivel rotation mechanism plus integrated linear side impact protection. Suitable from 45 - 105cm or from birth to approx. 4 years.

Why Should I Choose CYBEX Sirona Z i-Size Plus Car Seat - Midnight Blue?

Rear Facing Reduces Injury by 80%

This car seat provides excellent support for the neck and spine, which continue to develop in toddlers - not just newborns. The Sirona Z i-Size offers rear facing travel from birth to 4 years, greatly reducing the chance of physical injury in your growing child.

Enhanced Side Protection

The CYBEX L.S.P system is integrated into the seat. Its fold out tab feature extends outwards, reducing the gap between the seat and the side of the seat located closest to the car door. As a result, it decreases side impact forces by 25%. As well as supporting your child's neck and spine, the Sirona Z acts like a protective shield around this delicate area. On impact, the shield absorbs most of the force, reducing the physical harm on your child's delicate and developing organs.

One Hand Recline & Adjustable Headrest

Time for a snooze? Simply recline into one of 5 positions (rear facing) and 3 positions (forward facing). Plus the intuitive mechanism makes the seat easy to adjust with one hand, even with your child in the seat. As your child grows, simply adjust the head height - with 12 different positions, your little one will always be comfortable.

360 Swivel Seat

To get baby in and out, simply swivel the car seat towards the car door, lift baby in, then swivel back and lock into place before setting off. This intuitive rotating mechanism makes buckling-up much more intuitive on your back. If you wish, you also have the flexibility to face the seat forward from 76cm, or around 15 months. However, the inbuilt Driving Direction Control (DDC) provides extra safety by ensuring rear-facing travel until your child reaches the minimum age and size requirements.

Compatible with Base Z

To fit the Sirona, you'll need to purchase the compatible CYBEX BASE Z ISOfix Car Seat Base (sold separately). This allows you to slot the seat on and off with a simple click and also has a swivel base for ease of use. As part of the CYBEX Z-Line modular system, the same base is also compatible with the Cloud Z infant carrier, allowing for a continuously safe ride from birth up to 105 cm, approx. 4 years.
