It's then up to you to decide the travelling position of the car seat. As these are i-Size tested car seats, it is to be used rear-facing for a minimum of 15 months and 76cm tall. After this point, it can be used forward facing, but we would recommend rear-facing for as long as possible. It's great that you can use rear-facing for the entire time if you want the safest position. While the Cybex Sirona Z is suitable for use from birth it cannot be connected to any pushchair chassis, meaning it’s not suitable as a travel system. This removes the convenience of being able to transfer your baby from car to pushchair frame without waking or disturbing him. The Cloud Z lets you effortlessly move your little one from car to pram chassis, keeping them comfortable and secure at all times. Additionally, when the Cloud Z car seat is combined with the Cybex Z base, it can be rotated towards the car door for ease of fitting and securing your baby in the car.

We love the additional safety features that have been designed to keep your child safe and that they allow the safest rear-facing position to be used right up to their 105cm height limit. The rotating feature also makes it so easy to get baby in and out and they are really simple to install. i-Size includes a side impact test to ensure that the seats provide better protection from side impacts. This can make life much easier and convenient when struggling for space in the car boot, or if you simply find yourself out for longer than expected without your carrycot. Reclining Headrests – The CYBEX patented reclining headrest prevents the child's head from falling forward while asleep and guarantees optimal protection in the case of a side-impact. Your only other job is to extend the support leg until it touches the footwell and the green indicator at the front of the base turns to green. Just take care not to overextend the leg and cause the base to lift from the seat of the car. That's it!

It’s designed for babies from birth to approx 4 years or, more specifically, heights of 45cm-105cm and can take a maximum weight of 18 kg. In the following guide, we provide an overview of the Cybex Z Line Modular System, one of the safest choices for transporting your baby by car.

What makes the Cybex Z base even more appealing is it can be used until your child reaches 105cm tall, regardless of which way you use the seats. SensorSafeThe Sirona Z cannot be used without a car seat base, unlike the Cloud Z car seat which can be fitted with a seat belt (although this means it’s not i-size compliant). Lie-flat seats - Research shows that it’s healthiest for newborn babies to lie flat for the majority of the time when they’re sleeping or lying still for periods. The CYBEX Cloud Z i-Size features an ergonomic lie-flat position outside of the car. The Sirona Z is both rearward facing and forward facing but as it is an i-Size car seat, your baby must stay rearward facing until at least 15 months of age. It's alsoequipped with Driving Direction Control D.D.C, which prevents any misuse of the forward-facing position. In reality, this means it will not allow the seat to fully rotate forward until the harness is set to a minimum of 76cm (the approx height of a 15-month-old).

The 5 point harness is nicer to use on the Cybex than the Joie and it doesn't have so many confusing inserts. The Joie seats are also notorious for having very little leg room for the child rear facing (that's how they save space). Having the spin feature means that you can move from rear to forward facing easily too. On the previous model, there was Driving Direction Control which prevented misuse of the seat and forward facing too soon. Cybex have now passed this over to the parent to decide when to forward face, within the regulation advice. As lots of parents don't read instructions carefully, this could mean that they forward face sooner than advised. There is a red line on the car seats though that is a visual reminder that once the head rest reaches this mark, it should be around the height that the child can face forward.As safety features are obviously the most important feature of any car seat, these car seats have plenty. A difference in the two seats is that the SX2 has Advanced Linear Side-impact Protection that needs popping out on the car door side. In combination with the energy-absorbing shell, it can reduce the force of a side impact collision by 25%! The energy-absorbing shell is designed to flex with an impact and channel the forces away from baby too. More than 10 years of usability – This 2 in 1 seat protects your child with an impact shield until they are 21kgs and then by removing the impact shield and using the vehicle seatbelt until they reach 150cm. It includes an innovative rotating function, not only for the second stage seat but for the infant carrier too. This is a huge breakthrough in the infant car seat industry, as it offers parents the best of both worlds. Being able to detach your baby’s seat combined with the convenience of a rotating base for easy installation in and out of the car is hugely beneficial and a key reason why Cloud Z car seat bases are so popular. Rear-facing car seat - When positioned rear-facing, the seat significantly reduces the risk of injury in the case of a head-on collision. The Sirona S2 i-Size llows you to transport children rear-facing from 3 months up to 105cm approx. 4 years old. Depending on your preference, the Sirona S2 can also be used as a forward-facing car seat for children (starting from min. 76cm and over 15 months old). However Cybex recommend rear-facing in the Sirona S2 for as long as possible. The Sirona S i-Size has been a popular spin car seat for lots of parents and now Cybex have updated it with the Sirona S2 i-Size and SX2 i-Size! During the latest ADAC 10/21 testing, the SX2 was awarded Best in Class for the toddler car seat category and a Good 2.1 rating.
