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.

A real review.
Color: 2PC, Color: 2PC
When I saw the Unbreakable Teddy Extreme Bear 2.0, I thought, Finally! A toy that might survive my 9-month-old Rottweiler puppy, Pepper. She’s an aggressive chewer with a love for stuffies—she adores them, right up until she disembowels them and feasts on their cotton insides like a tiny, unhinged zombie. The toy’s name, "Unbreakabear," sounded promising. Durable? Stuffie-like? For large breeds? Sign me up! Fifteen minutes later, it looked like a crime scene from a horror movie. The Good: Pepper was IN LOVE with this toy... for about 10 minutes. The double pack is nice in theory—you know, so you have a backup when the first one inevitably doesn’t live up to its "unbreakable" promise. The Bad: False Advertising: This toy is marketed as "extremely durable for aggressive chewers." But let me tell you: Pepper’s chewing isn’t aggressive—it’s surgical. She shredded the bear’s ears, ripped off the tail, and then went straight for the brain like she was auditioning for Zombie Dogs Gone Wild. It didn’t even put up a fight. Durability (or Lack Thereof): Calling this toy "extreme" is like calling a paper towel roll a chew toy. One good shake, and the seams basically exploded in surrender. Safety Concerns: Once Pepper exposed the stuffing (and the metaphorical "brains"), it was a race to see if I could stop her from swallowing it. Stuffing everywhere. The floor looked like someone had murdered a carnival bear. The Ugly: Walking into the room after Pepper was done was like stumbling upon the aftermath of a teddy bear massacre. The "Unbreakabear" lay limp on the floor, its ears and tail missing, stuffing spewed around like it was the victim of a bear-sized horror flick. Pepper, triumphant, sat there with bits of fluff clinging to her mouth, looking like a deranged extra from The Walking Dead. Final Thoughts: If your dog is a light chewer who likes to gently cuddle their toys, this might be fine. But if your dog sees toys as a challenge, run. Stick to hard rubber toys, Kongs, or something without a vulnerable, squishy middle. As for the warranty? Sure, I could try to get a replacement, but what’s the point? Pepper will just go full zombie surgeon again. Would I recommend this toy? Only if you’re filming a sequel to Teddy Bear Massacre. For aggressive chewers, this is nothing but fluff and disappointment. Pepper’s Review: 5/5 stars for taste. 0/5 stars for durability.

Toy does not live up to its name
Color: 1PC
This product is not sturdy enough for an aggressive chewer as it is advertised. It took my 7-year-old "Rottie" approximately 15-20 minutes to have this "unbreakable, in destructive aggressive chewer" toy rip open and stuffing everywhere. A complete waste of money and I would not recommend this toy to anyone with an aggressive chewer.
