Cybex Sirona Gi i-Size 360 Car Seat with Isofix Base – Magic Black
The latest car seat in the 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 defence 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.
Five recline positions are available in either direction to ensure ultimate comfort for your child, whether they’re a tiny newborn or a fully-grown four-year-old (newborn inlay accessory sold separately).
Comfort and safety for their first four years with the Sirona Gi i-Size.
*compared to the same seat forward-facing in a frontal crash. Result of internal testing using 2022 ADAC frontal crash test criteria.
Product Features:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

Tough chewers favorite toy
Pattern Name: Classic Squeaky Tug, Pattern Name: Classic Squeaky Tug
This has become my dog’s favorite toy! It looks just like a corn on the cob! The toy itself is very durable. The rope that was attached got torn off within hours though. After much use, it still looks brand new minus the rope!

The Toy That Tires Out Your Dog So You Don’t Have To!
Color: Classic Blue, Color: Classic Blue
After trying a different interactive ball previously, I can confidently say this one is built much better. The construction feels more durable, and most importantly, it has held up well against my dog's enthusiastic chewing and chasing. Many interactive toys claim to be tough, but this one has actually survived extended play sessions without being torn apart.
The charging design is simple and well thought out. The ball twists apart easily to reveal the USB-C charging port, making recharging quick and convenient. Once charged, you simply twist the halves back together, press the power button, and it's ready to go. I appreciate that there are no complicated steps or special charging accessories required.
What really stands out is how engaging the toy is. The unpredictable movement keeps my dog interested and encourages plenty of exercise and mental stimulation. Instead of losing interest after a few minutes, my dog continued chasing, pawing, and interacting with the ball until he was genuinely worn out. For pet owners looking for a way to help burn off excess energy, this toy definitely does the job.
One minor issue I noticed is that on a couple of occasions, my dog was able to accidentally turn the toy off while carrying it in his mouth. It wasn't a frequent problem, but it did happen enough to be worth mentioning. Fortunately, turning it back on is quick and easy.
Overall, this has been one of the better interactive dog toys I've tested. It's durable, easy to charge, keeps dogs engaged, and provides the kind of activity that leaves them happily exhausted afterward. If your dog enjoys chasing moving toys and you want something sturdier than many of the alternatives on the market, this is a solid choice.

Great Entertainment, Short Battery Life
Color: Classic Blue
This is the first interactive ball I've found that my dog hasn't managed to destroy, which is impressive on its own. The ball keeps him entertained for long periods, and he loves chasing, nudging, and following it around the house. The material feels durable and has held up well to regular play. The one button operation is convenient, and the ball is easy to recharge and clean.
My biggest complaint is the battery life. On a full charge, it only seems to run for about 10 minutes before needing to be recharged again. Because of that, I find myself charging it frequently. Even with the shorter runtime, it's been one of the more engaging and durable interactive toys we've tried. Overall, a fun and sturdy toy that keeps dogs occupied, but be prepared for frequent charging.

Fun Dog Toy
Color: Classic Blue
This toy has been a lot of fun for our dogs. One of my dogs absolutely loves balls and is perfectly content to just carry this around in his mouth. The outer shell feels like a firm foam material. It is durable while still being lightweight enough for the dogs to enjoy.
The ball screws together, but it is designed well enough that you are not constantly worried about it coming apart. You have to intentionally press and twist it to open it, so normal dog play has not caused any issues. Inside is the motorized component, which is easy to turn on and recharge. It offers a few different vibration modes, which keeps things interesting.
The reactions from our dogs have been hilarious. One dog is convinced the ball might be plotting against him and keeps a suspicious distance. Another dog loves it so much that he holds it in his mouth while it vibrates, making his entire head shake. Our third dog plays with it exactly as intended, chasing it around and interacting with it normally.
The motor has enough power to make the ball bounce, roll, and move unpredictably across the floor, which keeps the dogs engaged. It has been a great addition to our toy collection and provides a different kind of enrichment than a standard ball. Overall, the dogs really enjoy it.

A fun toy
Color: Classic Blue
Our Malamute loves this ball. He likes to carry it around with him and let it will out of his grasp and pick it back up.
The outer ball it tough and durable, and so far it has held up well during play.
It does bounces more than rolls I expected a little more movement across the floor in a more rolling fashion... like those weasel balls from the 90s, but tends to hop and bounce in place. It does works best on hard floor where it has enough contact to move around and keep the dog engaged.
To charge you have to unscrew the ball in half to access the motor unit, and there is grease on the motor, so be careful when opening it and handling the internal piece. It is not difficult, but it is a little more complicated than a simple plug-in charging port.
The button on is also super hard to press. I you have to really squeeze it and even use a tool to turn it on. It has 2 modes though it is so hard to press I am not sure which mode I actually turn on.
It so far has been a fun toy for our young dog and has lasted our extreme chewer (only supervised play)
I would recommend if it went on sale.
