Installation with base: Pay attention to the i-Size logo. If a vehicle seat is marked with this logo, it is suitable for use with all i-Size child seats and will therefore not appear in our list of compatible vehicles. If your vehicle does not have an i-Size seat, please check the compatibility of your vehicle. If your vehicle is not displayed, please contact our customer service team.
*Category: 1 up to approx. 4 years
- Up to 50% higher safety levels*
- Rear-facing is one of the safest ways to travel. In the critical first moments of a front impact, the child's body is pushed against the padded car seat shell, minimizing movement and reducing the force acting on the child's neck. Mandatory up to 15 months (76 cm), we recommend keeping your child rear-facing for as long as possible. The Sirona Gi i-Size is designed for comfortable rear-facing travel until your child weighs 20 kg. (*compared to the same seat forward-facing in a frontal crash. Result of internal testing using 2022 ADAC frontal crash test criteria.)
- Quick and easy onboarding
- A stress-free start to your journey. Just swivel the car seat to face the car door and get your child onboard. You avoid back strain, while your child stays comfortable in any recline position.
- Optimal breathability
- Comfort in any season. All-round air ventilation lets air flow through channels in the car seat, carrying away heat and helping avoid a sweaty ride for your little one. The Plus version also includes mesh fabric that increases breathability up to six times compared to regular fabrics.

How to Use the Sirona Gi i-Size
Integrated Base
The toddler car seat has an integrated base which is installed using a load leg and ISOFIX. This ensures safety, stability, and an easier installation process. Look for the i-Size logo in your vehicle to check compatibility. If there is no i-Size logo but your car has ISOFIX, please check our Car Compatibility tool.

Will the car seat fit in my vehicle?
It is important to check whether the car seat is compatible with your vehicle before you purchase it. The car seat is approved for use in i-Size compatible vehicle seating positions as indicated by vehicle manufacturers in their vehicle User Guides. If your vehicle does not have an i-Size seating position, please check the Car Compatibility Checker on the CYBEX Website.
Can I use this car seat on a flight?
No, this car seat is not approved for use on an airplane.
Is it ok to keep using a car seat after an accident?
We at CYBEX strongly recommend that you replace a car seat after any kind of accident. This is because tiny hairline cracks, which may not be visible to the naked eye, can appear in the plastic parts of a car seat after an accident. These cracks can pose an increased risk to safety.
My car seat is faulty, how can I get it repaired?
Please refer to the retailer where you bought your CYBEX car seat. They will deal with the matter on your behalf.
Where can I get replacement parts for my product?
You can order replacement parts from a specialist retailer near you. To find a store near you, simply go to the Store Locator on the CYBEX Website.
How do I correctly secure my child in the seat?
Please observe the instructions in the User Guide. Adjust the child car seat to the size of your child and make sure that he or she is properly strapped in to ensure maximum safety.
My child keeps trying to wriggle out of the harness system. What can I do about this?
As a general rule, you can secure your child in the safest possible way if you follow these instructions: The impact shield should be positioned so it fits snug against the body without causing discomfort. The impact shield can also be adjusted in depth for a comfortable fit on the majority of models. You can tell that the impact shield is in the correct position if it is fully aligned with your child's body. Thick clothing prevents the harness/vehicle belt or impact shield from fitting tight to the body. Only a correctly adjusted restraint system can offer maximum protection. For this reason, your child should wear thin, close-fitting clothing. Thick clothing such as winter jackets and clothing with hoods (hoodies, teddy suits, etc.) as well as hats should be avoided. Once your child has been positioned in the seat, he or she can be covered with a blanket for warmth.
When am I allowed to use the Sirona's forward-facing position?
Once the child exceeds 15 months of age and has reached a minimum size of 76 cm you are allowed to use the forward-facing position of your Sirona car seat. This is not a must. We rather recommend transporting children in the Sirona's rear-facing position for as long as possible. The car seat allows rear-facing travel up to a height of 105 cm (approx. 4 years).
How can I clean my car seat?
Car seats can be cleaned using a vacuum cleaner or damp cloth. Sand or other dirt beneath the cover can also be removed in this way. To clean the plastic parts of the car seat wipe them with a cloth using a mild detergent and warm water. (Warning: Please do not use chemical detergents or bleaching agents under any circumstances.) Please note that a car seat should never be dismantled for cleaning. Please always refer to your car seat’s User Guide when carrying out care and maintenance on your car seat. Generally the seat covers are machine washable at a maximum temperature of 30˚C on a delicate cycle. If you wash them at a higher temperature, the cover fabric might lose its color or shrink. Please wash the cover separately and never dry it by machine or in direct sunlight. (Warning: Only the cover of the car seat can be machine washed. The car seat itself is not machine washable.) Should you wish to clean a car seat more thoroughly than recommended above, you will have to have it cleaned professionally. Please ask the retailer who sold you the car seat to refer you to a professional service.
Can I install a rear-facing seat on the front passenger seat?
Rear-facing car seats must only be installed on the passenger seat if the front airbag has been deactivated. Placing your child on a passenger seat with an activated airbag poses an enormous risk of injury, and we at CYBEX strictly advise against this. For other types of car seats check the user manuals of both your car seat and your vehicle to find out if you should deactivate the airbag. Statistics show that the safest place for a car seat is on the rear seat behind the front passenger seat. Side airbags do not put your child’s safety at risk. If you have no choice other than to use the front passenger seat, please ensure that the seat is pushed back as far as possible and that the airbag is deactivated.
How should the headrest be adjusted?
Only a headrest adjusted to the optimum height will give your child the best possible protection and comfort. The height can be adjusted to various positions. The headrest must be adjusted so there is no more than 2 cm between the child’s shoulders and the bottom of the headrest.
Can I use the car seat on laterally-facing vehicle seats?
It is not permitted to use the car seat on laterally-facing vehicle seats.
Can I use the car seat on rear-facing vehicle benches (e.g. in vans or minibuses)?
No. This car seat cannot be used on rear-facing vehicle benches.
What do I have to bear in mind when installing the Sirona in my vehicle?
First, select an appropriate vehicle seat. Unfold the load leg until it locks with an audible CLICK. Release the buttons of the ISOFIX locking arms and push them out of the base to their furthest extent. Insert the arms into the ISOFIX anchorage points (make sure they lock with an audible CLICK and that the safety indicators show green). Push the base towards the backrest of the vehicle seat until it is fully aligned with the backrest. Moving the whole car seat back and forth, and from side to side will further brace it against the backrest. Always make sure that the load leg is extended completely (pull out the load leg by pushing the adjustment button until it touches the vehicle floor). Pull the leg out and into the next locking position (make sure the load leg indicator on the base shows green).
Can I also use this seat in a car without ISOFIX anchorage points?
No, this seat can only be installed in vehicles with ISOFIX anchorage points, due to the fact that it must be installed with ISOFIX in every position.
What should I bear in mind when installing the car seat in my vehicle?
Before purchasing the car seat, it is important to check if it is approved to be used in your vehicle. If your vehicle has an i-Size seating position compatibility is given. If you have no i-Size seating position, please scan the dedicated QR-Code on your "Quick Start Guide" or use the specific weblink provided on the Packaging Box, to access the Car Compatibility Tool of your product. For proper protection of your child, it is essential to use and install the car seat according to the instructions given in the User Guide. It can be downloaded via the CYBEX Website.
Where should I install a car seat in my car?
Although it may be possible to install a CYBEX car seat on other seats in the vehicle, the safest place for a car seat is in the rear seat, behind the front passenger seat. We advise you to refer to the Car Compatibility Tool on the CYBEX Website. You can scan the dedicated QR-Code on your Quick Start Guide or use the specific weblink, provided on the Packaging Box, to access the Car Compatibility Tool for your product.
Can I use the car seat even when the side airbag is activated?
Yes, the side airbag can remain activated when using the car seat.
Is my child allowed to rest his/her legs on the rebound bar?
Relatively tall infants may rest their legs on the rebound bar. Bending the legs at the knee does not affect safety in any way. As long as the child has sufficient legroom you can use the seat in a rear-facing position.
The car seat is approved in compliance with the i-Size standard (UN R129). What does this mean?
i-Size is a European standard for car seats. Among other regulations i-Size states that infants must travel in a rear-facing position before the child's age exceeds 15 months and that, for the first time, side-impact protection is tested. To find out more about i-Size, check our Safety page on the CYBEX Website.
What's the difference between UN R44 and UN R129?
To simplify the process of choosing the right car seat, regulations and norms have been implemented to guarantee general safety standards worldwide. In most parts of the world including Europe, the UN R44/04 and UN R129 testing standards are in effect. R44 classifies child restraints (car seats) according to the weight of the child. However, children grow in different ways. For example, a child might be within the weight range of an R44 seat but their head may already be reaching above the top of the seat. On the other hand, R129 child restraints are classified according to the height of the child, and also specify a weight limit. This is intended to give parents more confidence that a child restraint will fit a child during a specific growth period. The aim of R129 is to make child restraints easier to install, to incorporate side impact testing to provide better protection from side crashes and to keep children in a rear-facing position up until they are at least 15 months old. It also aims to make child restraints more compatible with vehicle seats.
When does a car seat expire?
As soon as a car seat is installed in a vehicle, it may be exposed to high temperatures and high levels of light intensity. As a result, even high-quality and extremely age-resistant plastics such as those used by CYBEX can display certain age-related alterations. To ensure the safety of your child, we strongly recommend that the seats are not used for longer than the prescribed usage periods. A car seat will be designed to keep your child safe for a specific period in their development, for example from birth to approximately 4 years old for a Sirona Series seat. Sometimes they can be used for longer, for example our products for babies and toddlers can also be used for a sibling. To find out the approximate lifespan of your CYBEX car seat, refer to the User Guide or contact our Customer Service.
What kind of clothing should my child wear when seated in the car seat?
Thick clothing prevents the harness/vehicle belt or impact shield from lying tight against the body of the child. Only a correctly adjusted restraint system can offer maximum protection. For this reason, your child should wear everyday clothing. Thick clothing such as winter jackets and clothing with hoods (e.g. hoodies) as well as hats should be avoided where possible. Once your child has been positioned in the car seat, he/she can be covered with an extra blanket for warmth.
How do I know when my child needs to change to the next car seat?
We generally advise against switching to the next car seat prematurely. Even if your child’s feet protrude outside the car seat, your child has not necessarily grown out of the seat. However, if your child's head is protruding above the top edge of the highest headrest position, is taller than 105 cm, or weighs over 20 kg, it is time to change the car seat as it no longer affords sufficient protection to the vulnerable neck and head area. After changing the car seat, your child’s head should be positioned within the protective area of the height-adjustable headrest. If the new car seat has an impact shield, your child should be able to comfortably see over it. If your child disappears behind the impact shield, then he/she is definitely too small for the seat.
When is a child too big for the Sirona?
The Sirona can be used by infants between 40 cm and 105 cm in height or up to a maximum bodyweight of 20 kg (approx. 4 years).
