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.

Somewhat satisfied
Size: 38, Color: Light Khaki
I like them........ but don't love them. comfortable material but fit is a little off for me. Ordered these because of the length which was perfect....... until you sit down. They tend to hike up quite a bit which was the issue with even my no so long joggers. Figured these would solve that high-water-esque issue but they did not. They really ride up the legs when seated.

Look great on my preteen with just a little chub who wears 32 or 34" with 32" inseam
Size: 32, Color: Navy, Size: 32, Color: Navy
I got these in a 32" waist for my preteen son who is between 32 and 34 right now. He either has pants that are too tight or too loose and he feels like they're falling off all the time. These fit him perfectly. The length hits just right, the stretch in the waist is enough that they fit well without squeezing his pre-growth-spurt chub out in an unflattering way. They are comfortable enough he came out with a smile and asked if he could keep them on. That hasn't happened in a very long time. He loves the pockets. I'm really hoping that when he grows a few more inches they still look as good on him. He did say they conduct the temperature a lot, so if you're wearing them outside on a cool day, you might need to layer a bit. They also do have a bit of a swish too them as they are the water repellant material, but it's a quiet swish rather than the 80s/90s rain wear swish too many of us remember too well. If you have a little chub and want to look sleek, these are a great option. I'm impressed with how flattering they are on his current build. He wears pants with a 32" inseam and these fit him just like it's shown in the ads, snug right around the ankle by the shoe. I haven't included pictures of him wearing them as there are already quite a few of those, but these do attract dog hair more than an average pair of jeans in the crotch and ankles. Why those spots, I have no idea. I just know that our cream colored Siberian husky is shedding a ridiculous amount right now and you can really see it on these pants, so be prepared to get some sort of lint roller/remover for these. As a side note, it also had the appearance of pilling in some of the pictures I took, but I couldn't see or feel anything there, so I'll be watching to see if there is randomly the same dust all over the pants or if pilling starts to happen. Also, he knows chub or no chub he's amazing and handsome and I'm proud he's mine, so it's not me being a harsh mama, just an honest mama in this review.
