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.

Stylish and functional.
Color: Green, Color: Green
First, I love the color. Earth tones are my go to. This is a nice shade of olive green. The design is stylish. Minimalistic is also my preference. It’s very much form and function. So I’ve mostly used this hiking. It’s big enough to store everything I needed for longer or overnight trips. I had a light jacket, sunscreen, flashlight, bug spray, several bags of snacks, a book, wipes and a water bottle. I could have packed more honestly. It’s waterproof and the material doesn’t snag or scratch. I’ve also used it for travel, mostly for my art supplies. It’s sturdy so my sketch book doesn’t bend. Theres a dozen different pockets and compartments, so everything can be separated from each other. The size is good, the strap lengths are long and easily adjustable. The only downside is the compartment for a water bottle or travel mug is pretty tight. Other than that I like it a lot.

Good solid backpack
Color: Latte Beige, Color: Latte Beige
I’m really happy with this backpack. It fits my Lenovo Legion 5 16'' perfectly with just a little room to spare, but not so much that the laptop shifts around. The material feels sturdy and durable, and the waterproof design gives me peace of mind when I’m out and about. The travel strap on the back is a huge plus for me—it makes traveling so much more comfortable. There’s also plenty of space for my things, and I can easily use it as a weekend bag for 1–2 days without it feeling bulky. The price is not bad, for the quality you receiving is honestly really good. If you’re looking for a reliable, well‑made backpack with lots of room, this one is a great choice.

A really nice one!
Color: Latte Beige
This was so close to perfect for me! Love the fabric, the structure and the setup. I just didn't love the really thick padded laptop pocket. It made the bag bulky than necessary and I don't usually carry a laptop.
