Meet rear-facing travel made simple with the CYBEX Sirona G3 car
seat, offering up to 50% higher safety levels* for your child.
 

Its 360° rotation makes getting your child in and out far easier by
positioning them at a much more manageable angle. Specially
designed to provide an ergonomic sitting position throughout, it keeps
your child’s legs and hips in the posture-friendly M-position to aid their
development as they grow.
 

The advanced Linear Side-Impact Protection System adds 25% more
protection in a side collision**. As part of the Modular G3 family, Base
G3 used for the Cloud G3 fits this seat perfectly, providing a secure
solution for the first four years.

UP TO 50% HIGHER SAFETY LEVELS*

Children must travel rear-facing until they are 15 months old and the Sirona G3 delivers up to 50% better protection until they are 4 years*. In a frontal collision, the seat’s padded shell absorbs and distributes the impact while holding the child close, limiting motion and reducing strain on their neck.

EASY ON AND OFF-BOARDING

A 360° rotation mechanism makes it so easy to get your child in just the right position to get them in or out of the car, even when reclined, making it much quicker and better for your back. 

25% MORE SIDE PROTECTION**

The advanced Linear Side-impact Protection combined with an energy-absorbing shell and a specially designed headrest gives your child 25% more protection in a side collision2 keeping them safer on every trip. Advanced means it opens automatically when take out of the box,
one less thing to worry about. It can easily be folded away when space is limited.

MODULAR SYSTEM

As part of the Modular G3 family, both the Cloud G3 and Sirona G3 fit Base G3 and Base G. Once your child has outgrown the infant car seat, the Sirona G3 can simply be installed with just one click. Thanks to ISOFIX connectors, it provides a user-friendly, safe foundation for the
first 4 years.

ISOFIX AND LOAD LEG

Extra stability and safety in the car, with a load leg to prevent forward rotation  in the event of an accident and user-friendly ISOFIX fastenings that connect a separately purchased base directly onto the chassis of your car.

DOUBLE NEWBORN INLAY ACCESSORY***

Two cleverly designed, removable inlays let you use the car seat from day one. The first, newborn inlay is for babies measuring 40 to 60cm. It sits underneath a soft, secondary inlay to keep their legs in a posture-friendly M position to support spine and hip development as they grow.

BELT HOLDERS

Cleverly designed belt holders keep the harness straps out of the way to avoid your child accidentally sitting on them when putting them in the car seat, making the whole process so much smoother and simpler for parents.

MULTIPLE RECLINE POSITIONS

Always find the perfect traveling position as your child grows. 5 different recline levels, in both front and rear-facing positions are specially designed to provide a comfortable, ergonomic position for those welcome mid-trip naps or on longer journeys.

Best liner socks EVER
Size: Medium, Color: (348) Silica Green / Silica Green / Hydro Green
I have them in every color and used to get them from Sams, but they stopped selling them and I was lucky to find them on Amazon. Got all colors again. They stay, it's all I'm gonna say! And don't show in any of my tennis shoes. Absolutely love them and wear them until they get holes. They last a LONG time too. They're on the thin side and my foot loves them because they tend to get hot. There's no shrinking, they wash great with exception of the white ones I couldn't manage to keep white - they turned a bit greyish.

Great socks
Size: Medium, Color: Pink - 647
Well-made and comfortable to wear. Great for golf and other outdoor activities. Like them because they do not show above shoes.

These ACTUALLY stay put all day long - I was skeptical, but am so glad I took a chance on these
Size: Medium, Color: (014) Halo Gray / Halo Gray / Castlerock
I was so skeptical about whether these would stay on my feet all day without sliding down into my shoe - I’ve tried so many socks in the past with the silicone strip on the heel which failed. I’ve owned these for a couple months now and they have never slipped down - they stay put all day! I love the variety of colors to choose from, and the value per pack is great since six pairs come per pack (I thought it was only three when I first purchased and was pleasantly surprised by the additional pairs). They also have perfect thickness - not too warm to wear during the summer months with sneakers; I live in a tropical climate, though, so I’m not sure how they will do in cooler climates. I’ve washed each pair once or twice and the color and quality of the silicone has stayed so far (knock on wood). Overall: high recommend based on my experience so far!
