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.

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.

Couldn't get the zipper button open!
Special Size: Midweight, Size: 38W x 30L, Color: Dark Midnight Wash
Returned. They are probably a good product but I have arthritis in my thumbs and it was excruciating to try to undo the button above the fly. I seemed like like the button hole was too small. Maybe a gorilla finished final assembly?

Suprisingly great jeans.
Special Size: Midweight, Size: 29W x 32L, Color: Grey Wash
Love the fit and style of these. The waste is abnormally small, I purchased a 29 but also 30 would have been better. The rest of the fit is great, color is great, good mix between stretchy and stiff.

Too baggy! (UPDATE): Bought this style of jeans again and they fit great!
Size: 31W x 30L, Color: Tinted Light Wash
These jeans are too baggy for my liking. Edit: I purchased more jeans of this style recently again and for some reason they fit a lot better to my liking than before when I first left the initial review for this. I have updated my review from 3 stars to 4 stars now. I purchased the black, grey, dark wash and tinted medium blue, and all 4 had a good fit on me. My original review stated that it was too baggy but the 4 jeans I just bought had a fitted look which is what i prefer, not too baggy and not to slim/skinny. I want to point out that the fit varies from the color choices. For example, the black, grey and dark wash jeans, i went with a size 32x30 because 31x30 for those colors were too tight/slim on me and for the tinted medium blue, i downsize to 31x30 because 32x30 for this color is too baggy. So buy the size you usually wear and if it's too slim or baggy then send it back and size up or down. Buying jeans on Amazon, i feel that you will have to buy a few different sizes and see which one fits you the best and then go from there. Edit (3/7/26): sizing is very inconsistent. So my previous edit above stated that the jeans I recently purchased fit great on me, and that's true, so I decided to buy another jean, same color and same size, this time the jean fit way too small/tight. I feel like amazon needs to do better quality control on these jeans. How does 2 pairs of the same jeans/color/size have such an inconsistent in size/fitting to it!
