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 solid chair for the budget conscious sitter.
Color: Black, Size: Pack of 1
While this is not THE most comfortable chair, let's face it - if you sit for long periods, what chair IS? I bought this chair because I'm making a career change. I've returned to school and spend hours at my desk. At the age of 50, sitting for a long time with my nose pointed toward a book can be hard on the seat, back and neck. I looked at all kinds of office chairs and settled on this one, primarily because it was on sale, was in my budget and so I clicked the "Add to cart" button and hoped for the best. It was delivered, and I had to work that evening, and when I got home my 17-year-old son had assembled it. My theory on the simplicity of assembly can be deduced from that sentence above. He didn't have any extra parts left over and the chair was complete! I sat down. I leaned back. I shifted the lever that keeps the chair in an upright position and sat straight up. Okay! I can live with this. It has been almost two full months of using this chair and I have no problems. Pros: easy to assemble sufficient comfort level - adequate cushion in the seat can be leaned back or pop the lever in to stay straight up rollers on bottom headrest is adjustable affordable easy to clean arm-rests can be moved up or down height adjustment is self-explanatory - you'll figure it out the "lumbar" support is actually comfortable - it's "there" if you back up to it but if you scoot forward just a bit, you won't feel it if you don't want to sit like that Overall this seems like a chair that's going to last me for a few years, at least, and not fall apart. In the context of size, I'm not a small or extra larger person. I'm an average middle-aged woman with meat on the bones. The seat is plenty big enough. I would recommend this chair as an upgrade to the hand-me-down office chair that just isn't comfortable any longer.

Love this chair!
Color: Black, Size: Pack of 1
I had an office chair that cost $300 more than this chair - had it for years, then things started breaking down on it. I read about this chair and, wow! I wish I had known about it sooner. It's more comfortable and it's not a chore to sit for a couple of hours working on designs. Wonderful design - supports my back well and it's very stable, easy to adjust.

Good chair with some quality issues
Color: Black, Size: Pack of 1
I've been using this chair for 12+ hours a day for the last 5 or 6 months and so far it is much better than my last chair I bought at Staples with a few problems. First, overall the chair is still comfortable when set properly, the cushion on the bottom is a little worn out but is still comfortable and I find the backrest comfortable except for the lumbar support which has very little cushioning and feels like a plastic brick being pushed into my back, however I find that I can keep it mostly out of the way most of the time and it isn't noticeable when I carry most of my weight on my upper back area while reclining. The reclining angle is super comfortable and the mesh on the back is not noticeably worn out. I like the headrest which is made of a cushioned mesh, its not better than a pillow but it's very comfortable to be able to rest your head in a chair you are going to sit in for long hours and gives good support. The arm rests don't feel amazing, they have a very stiff plasticky cushion feeling that I'm not much a fan of in terms of pure comfort but they get the job done as I mostly only rest my elbows on them when typing. The arm rest adjustment has a pretty good height range and I keep them at the highest settings and set as close to the chair as possible. While the chair may be comfortable, I have had some quality issues that bring down my opinion of the chair. First, my right arm rest does not go as high as my left arm rest and I have to set the left one down two positions to match the right one Second, the back rest locking for the upright position is broken but I can rarely get it to work as long as I don't put much weight on the back. I would imagine that most people would want to lock the chair upright as opposed to the other positions. Third, the 3 screws holding in the backrest untighten themselves over time, causing the backrest to move to its furthest back position and rock left or right if I lean on either side. When I tighten them again they will usually last about 1-2 weeks before becoming mostly loose again. There is no danger of the screws completely falling out though, just losing their tightness Lastly, I'm not sure how stable or secure the wood panel at the bottom of the seat that everything attaches to is strong enough, I used to have my armrests adjusted out further from the center but when I would lift up on my arms to adjust my seating position I would occasionally hear a sound of the wood stressing under the torque from the armrests. since I moved both armrests as close to the center as I can this has not happened; I would like them a little bit wider but I don't want to risk breaking the chair over it. Also, one of the factory-installed screws in the bottom seat panel fell out and wont stay back in but I haven't noticed any problems other than the risk of stepping on a screw caused by it While this is likely the most comfortable chair I've ever sat in, I have to give it 3 stars for the uncomfortable lumbar support and the quality control issues. If the QC issues were fixed I could easily give this chair a 4 star review

Fantastic!
Color: Light Grey, Size: Pack of 1, Color: Light Grey, Size: Pack of 1
Outstanding quality and incredibly easy to assemble! The back support is a perfect 10/10. I was debating between the M57 and the B100, and the B100 definitely won me over. The materials feel premium and durable. Highly recommended!
