Choosing the Best Cybex Car Seats: Why Should You Trust Cybex?

Selecting the best car seats might seem easy, but it's pretty tricky since you want the best for your child.

So, find all you need to know about the best Cybex car seats and pick your final winner!

1. Safety & Security

cybex car seat reviews 2022

Since all Cybex car seats have adjustable headrests and LSP, they will fully protect your little ones.

Namely, the construction will support your kid and keep their bodies properly, especially if they're asleep.

In addition, of course, the seats will provide enough softness and comfort, and the LSP saves them more than the regular side-impact protection.

However, rear-facing seats have the load leg, the extended part that offers more security in the frontal crash.

And, the SensorSafe app follows the conditions inside the vehicle even if you're not around.

2. Ease of Use & Installation

All seats come with the LATCH installation type, and some include seat belt installation. So, it would be easier for you to install and move the seats among more vehicles.

But, you need to install them properly, so follow the shoulder belt and the lap belt path and connect them correctly to keep the baby safe.

3. Easy Maintenance

cybex sirona car seat reviews

Many Cybex seats have removable fabrics, are dishwasher-safe, and are easy to clean and maintain.

Still, pay attention to the instructions and labels to prevent quality and shape.

4. Size & Weight

Since numerous Cybex seats are lighter than other brands, they might be ideal since you won't have to struggle with a cumbersome car seat.

Still, you need to check the vehicle basket's depth and your vehicle's size.

5. Comfort

With numerous reclining positions regarding the whole seat or only the headrest, your baby will have enough comfort and softness for various activities, including sleeping.

For instance, the Cloud Q has a lay-flat position so that your baby can fully stretch and enjoy the ride.

So, check which seats offer the lie-flat option for more comfort.


What is the safest car seat 2022?

The safest one is the CYBEX Sirona S with SensorSafe Convertible due to the SensorSafe app, LSP, 360-degree rotation system, and the extendable load leg for the kid.

Where is the CYBEX car seat made?

The seats are made and produced in Germany.

Who makes CYBEX car seats?

Cybex and Goodbaby International Holdings Limited have produced seats in Germany and China since 2014.

Is CYBEX a luxury brand?

Yes, it is. Cybex is a German car seat brand, the leader among luxury brands.

The brand covers everything - from car seats, carriers, and similar children's restraint systems and accessories to furniture and pushchairs.

The Cybex brand's products are divided into three categories: silver, gold, platinum categories. 

How long can a baby stay in a CYBEX car seat?

Your baby can use rear-facing Sirona models from birth to 15 months of age and then rear or forward-facing up to 4 years of age.

All other Cybex infant seats can be used up to 18 months of age.

How long does the Cybex Aton 5 last for?

The Cybex Aton 5 car seat is an ideal model for newborn babies and premature babies.

However, the car seat will last approximately only a year if you have a more giant baby or child of similar ages.

Due to its specific design, you cannot use it for too long as the other regular infant car seats.

Hence, it would be best to check all details and see whether the seat might or might not be appropriate for your kid's needs.

Which car seats are compatible with the Cybex Gazelle S stroller?

cybex booster car seat reviews

The Cybex Gazelle S stroller can work well with multiple car seats, thanks to the specific car seat adapters for maximum safety and stability.

The CYBEX Gazelle S adapters permit the fitting of CYBEX car seats, Maxi-Cosi Mico 30, and Nuna PIPA rear-facing infant car seats to the frame of the Cybex stroller.

The car seat adapters convert the Gazelle S into a specific travel system, corresponding to your needs and making it easier to transition the baby from the motor vehicle to the stroller.

What is the difference between Sirona Z and Sirona Zi?

Both child restraint safety systems provide rear-facing swivel and travel car seats. They fit and support kids from birth to age four. But, there is a difference between the two systems.

Namely, the Z i-Size is a part of a modular system that comes with a car seat base.

On the other hand, the Zi i-Size is a stand-alone car seat, coming with its specific car seat base attached to the shell and frame.

What is the difference between Cybex Sirona?

For instance, the Z and Zi car seats differ in the car seat bases. The Zi comes with the base attached to the seat, which is not the case with the Cybex Sirona Z.

In addition, the Cybex Sirona Z cannot be attached to the pushchair chassis. Therefore, it cannot be used as a travel system.

The Cybex Cloud Z needs a separate SensorSafe Smart technology, and you will have to pay extra money unless stated differently.

And you can find five or six different subcategories of the seats, with their own specific pros and cons, similarities, and differences.

What is the difference between Cybex S and S2?

As the very name states, the Cybex Sirona S2 is the advanced version of the Cybex Sirona S car seat.

Being an advanced version, it features all the existing benefits in the Cybex Sirona S regular model.

However, the protection system technology is the main difference between the old and the new model.

The Cybex Sirona S2 2021 contains the newly updated and improved Preset Side Protection System foe Error Free installation the original Sirona S car seat didn't have.

So, it will increase the protection and safety standards of your little one and let you know immediately was there any mistakes with the SensorSafe and comprehensive protective technology.

Britax vs. Cybex: Who is the winner?

It's challenging to say which car seat is a better pick. Both seats offer extraordinary benefits, especially the Cybex Sirona S with the SensorSafe system and swiveling design.

However, if we compare it with the Britax Boulevard, for instance, safety experts are more likely to choose the Britax model over the Cybex one. Why?

The Britax Boulevard has more excellent safety ratings, is more affordable than the Cybex Sirona, and offers better design and protection features than the Cybex Sirona.

You can find numerous other safety reviews, such as Consumer Reports, Strolleria, Baby Gear Lab, and others, to compare the seats, but you will meet the same result.

What accessories does the Cybex car seat come with?

You will find a wind range of car seat accessories, including:

- car seat base for specific models

- stroller parasol

- car seat covers

- cup holders

- stroller holders

- summer seat liners

- insect net seats

- shopper bags

- stroller wheels

- bring the straps together 

- find the puzzle buckle, click it in and pull the straps to tighten the baby 

- push the gray button-down and lengthen the straps 

- remove the pants from the straps, and remove the insert 

- pull the harness there, and you will get more space as the kiddo grows

- straps will come across the top of their shoulders 

- lift the back of the headrest

- find a little gray lever, pull it up and moderate the height options as your kids grow

Are Cybex bases interchangeable?

Yes, they are. You can install, for instance, two car seat bases in two different motor vehicles.

Thus, you will get quick access to both seats and use them interchangeably between the two motor vehicles.

The process won't be either time or energy-consuming, and you can quickly transfer the seats between the vehicles, even if you travel long distances.

Which car seats are compatible with the Cybex Z base?

The CYBEX Base Z is an ISOFIX (LATCH) car seat base works well with two different Cybex child car seats.

The car seats include the CLOUD Z car seat as the first of the car seats, suitable from birth to 18 months, such as the CYBEX Cloud Z i-Size car seat with the SensorSafe system (Autumn Gold.)

Another model is the CYBEX Sirona Z i-Size car seat 2020 Autumn Gold. The car seat supports kids from their birth up to 4 years.

How do you install Cybex without ISOFIX?

CYBEX car seats that are created with the ISOFIX Connect System might also be used and installed in various motor vehicles that are not equipped with the ISOFIX system.
