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.

Good little party speaker!
Style: X3206 with One Woofer
For the price, this thing is amazing! Let me cite pros and cons: Con - On battery, the bass is not very good and overall volume is not very loud. However, if you have to run on battery for a small group, it is definitely "loud enough" for a group. Such as background music for an outdoor dinner party, or cocktail party. Pro- Plugged in, the power and bass is impressive! MUCH Better than I expected. Connected it to my laptop for karaoke and it is definitely plenty loud for any house party, or plugged in, loud enough for any backyard party! ALSO - the lights that are included are pretty cool. And, it has a variety of input connectors for just about any application. Again, in this price range, it is a hit!

Big controllable sound! Buy it
Style: X3206 with One Woofer
Just buy this! It will not disappoint. I bought it for a family reunion gathering in a 5000 square-foot backyard garden. There were multiple seating stations all around and it could be heard from any location without being turned up all the way. Even at the halfway point it is extremely loud. I love that it is waterproof Because I left it outside overnight when the sprinklers came on and it was just fine. The battery charge lasted for five or six hours. It doesn’t take long at all to recharge. It has a good weight to it so it’s not going to blow away, but it’s not too heavy to move around. I use it in the garage. I use it while cleaning. I use it on campsites. It is a fantastic speaker. It is a little large, but not too large that it’s not manageable. I only say that because I have a BOSE small Bluetooth speaker and if you’re used to that small size, this obviously is larger. I have no Bluetooth connection issues with it at all. It plays my Amazon prime music from my phone library perfectly. I would absolutely buy one again. While my BOSE Bluetooth speaker is great, I needed it as an extra boost for a DJ party atmosphere and this did the trick. Here’s a tip, create a playlist on your phone for hours of streaming music or go to YouTube and save your favorite music videos of live music DJs and you have your very own DJ all night.
