The latest car seat in our successful Sirona line is the most comfortable yet: the Sirona Gi i-Size. Extended rear-facing for safer travel up 20kg, this car seat also features integrated Linear Side-impact Protection for defense from all directions.

A range of innovative features also upgrade your child’s comfort, including 360° rotation in any recline position with the easy rotation handle, for smooth on and off boarding. Innovative all-round air ventilation means the ride stays cool, and you have the option of choosing mesh fabrics for maximum breathability with the Plus fabric version.

Five recline positions are available in either direction ‒ tailored comfort for your child, whether they’re a tiny newborn or a fully-grown four-year-old (newborn inlay accessory sold separately). 360° of comfort and safety for their first four years: the Sirona Gi i-Size.

CYBEX were awarded Which? Baby and Child Brand of the Year in 2024!

Features:

Up To 50% Higher Safety Levels*

Extended rear-facing – one of the safest ways to travel in a car seat. In the critical first moments of a frontal impact, the child’s body is pushed against the padded car seat shell. This keeps movement to a minimum and reduces 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 your child to sit comfortably rear-facing until they weigh 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 using the easy rotation handle to face the car door and get your child onboard, in any recline position. You can avoid back strain, while your child stays comfortable in the recline position that fits them, whether they’re a newborn or a toddler. Switching from rear to forward-facing travel is just as easy.

Optimal Breathability

The all-round air ventilation of Sirona Gi i-Size allows air to flow through ventilation channels within the car seat, carrying away heat and helping avoid a hot and sweaty ride for your little one. Choosing the mesh fabric available on the Plus version increases airflow even more – with up to 6 times more breathability than comparable car seat fabrics. The clear choice for comfort in any season.

Easy Onboarding

When you’re getting your child strapped into the car seat, you need all the help you can get. The Sirona Gi i-Size features ingenious loops designed to keep the harness out of the way as you get your child onboard.

Grows With Your Child Up To 4 Years Old

As your baby grows, adjust the Sirona Gi i-Size headrest for a comfortable fit at every stage. 12 positions allow a tailored fit to your child, with the harness lengthening automatically with each adjustment. And it can be adjusted with one hand for extra ease of use.

Side-protection

The Linear Side-impact Protection defends your child against the force of a side impact. Working together with the energy-absorbing shell, the L.S.P. System significantly reduces the effect of impact force on the child.

Always In A Comfortable Position

For every moment, whether your little one is a newborn or a growing child, the ideal recline setting is available in both riding directions – and in the boarding position, too. And when your child falls asleep in the seat, you can recline it with one hand, letting them dream that little bit longer.

Straightforward Installation

It only takes moments to set up your Sirona Gi i-Size. Use an ergonomic handle to click the ISOFIX into the vehicle seat and extend the load leg down to the car floor. Both provide stability and extra safety in the event of an accident. Visual indicators help you confirm the seat is ready to protect.

On the fence.
Scent: Citrus
Long lasting but don’t take anything off the skin it’s great for moisturizing but not for washing anything away like deodorant it can’t handle the task, smells great during wash but not long lasting after.

Felt commercial vs natural
Scent: Tea Tree
I got the tea tree soap and the first thing I noticed was it has a strong perfume smell that I don’t believe to be natural because I’ve had other kinds of tea tree soap bars and I prefer the other bars over these because I could actually smell the tea tree sent with the other bars and it was a nice mild scent in comparison to these that have a strong perfume scent. This soap didn’t bother my skin but it was not as effective as my other tea tree soap purchases I made prior to trying these. It came with a soap sack to help build up a soap lather but it was so cheaply made it felt apart after the second use. This soap appeared commercial in my opinion and it was made in china and I didn’t notice this prior to making my purchase. I would have avoided making this purchase knowing what I know now including my personal experience using this product.

Gentle but Effective Cleaner
Scent: Tea Tree
This tea tree oil soap does an excellent job of cleaning without being harsh on the skin. It removes dirt and oil effectively, yet my skin never feels dry or tight after use. The lather is rich and smooth, and the light tea tree scent feels fresh and refreshing. Thanks to the shea butter, my skin feels soft and moisturized, making it great for daily use on face, body, and hands. A solid choice if you want a natural soap that’s both gentle and effective.

Don't Be Fooled By The Title On The Box🩷
Scent: Citrus
Let me simply say that I KNOW this soap is the "real deal". I am not one to give an average product an excellent rating. When I spend my money on a product, I write about the positive (if any) as well as the negative. Since being sick from 2015 to 2019, my skin tone changed from a medium "sienna" to having an unnatural ashy cast that that makes me always look ill although I am well ,now. When I looked at myself in the mirror in natural light, that "ashy cast" to my complexion didn't look healthy or attractive. I had come to accept that this would probably be an issue the rest of my life. I am a lady that never used foundation makeup but, decided to try it as a last resort. Using foundation makeup only made me look worse. I accidently came across this item while searching for another type of soap. When it arrived and I saw "Men's Soap Set" on the box 👀😩, I was devasted. I had ordered something that I never intended to order. I was about to return the item when I heard a clear message in my mind directing me to try the soap. Several months ago, I prayed and asked Our Creator and Lord to make my complexion healthy in appearance. That prayer came back to mind and I tried the soap without any further hesitation. I wasn't expecting anything but, to my surprise the soap immediately started removing that "ashy cast" from my face. Let me make it crystal clear that I had tried dozens of other soaps and products that did absolutely nothing to help. I have only used this soap once. As I write this review it is almost 7:00pm ET and I haven't turned the lights on inside of the house yet. I glanced at myself in the mirror and I can see myself and that healthy tone coming back. My prayer has been answered and I'm beginning to look healthy again! As for this soap, I couldn't ask for a better value for the money. This soap is of amazing quality. I will continue to use it. Don't be fooled by what's written on the box. This soap is for ladies as well. I can only speak about my personal experience but, it's a superior product in my opinion and definitely worth a try for anyone that has had an unnatural change in complexion. I give it five SUPER SIZED stars!!! 🩷🩷🩷

You'll be disappointed if you want pine scented soap.
Scent: Cedar
Has a mild scent, and not very pine like. I was disappointed. Grandpa's is still the best. I'm going to melt down the remaining three bars of this soap and add my own pine oil. The soap quality is good; long lasting bars that lather well.
