CYBEX Sirona G3 i-Size 360° Rotating Toddler Car Seat - Rear-Facing to 4 Years

The CYBEX Sirona G3 i-Size is a 360° rotating toddler car seat designed to keep children travelling rear-facing - from approximately three months up to four years old, and from birth with the optional double newborn inlay accessory (sold separately). Certified to UN R129/04 and holding both an AGR back health seal and a Red Dot Award, the Sirona G3 combines proven safety engineering with the kind of everyday practicality that makes a genuine difference across thousands of car journeys.

Up to 50% Higher Safety Levels Rear-Facing

The Sirona G3 is built around a straightforward but important principle: rear-facing travel is significantly safer for children than forward-facing. In a frontal collision - by far the most common type - a rear-facing seat's padded shell absorbs and distributes impact force across the child's back, shoulders, and head, rather than placing that force through the harness straps alone. CYBEX's internal testing shows that the Sirona G3 used rear-facing delivers up to 50% better protection compared to a conventional forward-facing seat. UN R129/04 (i-Size) regulations require all children to travel rear-facing until at least 15 months, and we strongly recommend continuing in the rear-facing position for as long as the seat allows - up to 105 cm in height, or approximately four years old.

360° Rotation for Effortless Boarding

One of the most challenging aspects of daily travel with a toddler is getting them settled in their seat without awkward lifting, twisting, or straining your back across the car door frame. The Sirona G3's 360° rotation resolves this directly. Rotate the seat to face the door, secure your child in comfort, then swing the seat back into the travel position. The rotation works in all recline positions, so you never need to adjust the recline angle before you can rotate - particularly useful when you have a sleeping child to move. The same smooth process applies when you arrive at your destination.

Advanced Linear Side-Impact Protection (L.S.P.) - 25% More Protection

The Sirona G3 features CYBEX's Advanced L.S.P. System, which deploys automatically when you first take the seat out of its packaging - no setup required. The energy-absorbing wings combined with a specially designed headrest reduce the force of a side collision by approximately 25% compared to the same seat without L.S.P. (based on internal testing). If space is limited - for example when fitting three seats across a rear bench - the inner L.S.P. wing can be folded away, though CYBEX recommends always keeping the door-side wing extended for maximum protection.

AGR-Certified Ergonomic Comfort

Holding the AGR Seal of Approval from Germany's independent back health organisation, the Sirona G3 is designed to support healthy posture throughout your child's development. The M-position keeps legs and hips correctly supported, aiding hip joint development over the months and years of use. A height-adjustable headrest grows with your child, and five recline levels - available in both rear-facing and forward-facing orientations - mean you can always find a comfortable, well-supported position whether your child is awake and alert or napping mid-journey.

Practical Details That Make a Difference

Belt holders keep the harness straps neatly out of the way when you're settling your child into the seat - a small detail that significantly reduces the fuss of getting a wriggly toddler buckled in. All-round ventilation keeps the seat environment comfortable across longer journeys and warmer days, with Plus Line versions adding a premium mesh fabric six times more breathable than conventional cover materials.

Part of the CYBEX G3 Modular System

The Sirona G3 is part of the CYBEX Modular G3 family, and fits onto the same CYBEX Base G3 as the CYBEX Cloud G3 infant car seat. If you started with the Cloud G3 from birth, transitioning to the Sirona G3 requires no new base purchase - it clicks onto the existing Base G3 in a single step, supported by ISOFIX connectors and a load leg for a stable, secure fit. Together, the three products form a complete birth-to-four-years solution; you can find the full set in our CYBEX G-Line Car Seat Bundle.

Please note: the Sirona G3 requires the Base G3 for installation in all vehicles. Unlike the Cloud G3, it cannot be secured using a vehicle seatbelt alone. Always verify compatibility using CYBEX's Car Compatibility Checker before purchase.

“My heart bows to you and you only, Huntress.”
Format: Kindle
3.5 🌟 This book popped up in my KU recommended reading suggestions and the synopsis sounded like what I was in the mood for. I'm so glad I took a chance on it. I went into this knowing absolutely nothing about it and ended up really liking it. I love when this happens. The main characters are likeable and I easily found myself rooting for them. There is a mystery element to each of their backstories that I enjoyed watching unfold and can't wait to get more of. Wolf, in particular, has me fixated. Love him. I found this to be an entertaining, addictive read with a plot that moves along at a good pace. It reads so easily I found myself very reluctant to put it down. Lots of twists and turns and the angst is there. A good set up for the next book to come, for sure. My issues with this book....the dialogue feels a bit juvenile at times and there is a repetitive over use of a particular word phrasing that I found myself giving the ole eye-roll to. There are, without a doubt, some pretty cliche moments that gave me a bit of the cringe. I think this could've certainly 100% benefited from more depth regarding the world building. Perhaps the world building was sacrificed to keep the pacing quick? Just a guess. Also, the lack of consistency of character for the FMC was really evident and so she feels quite illogical at times. Overall, this was a fun and enjoyable read that hit the spot well enough for me. That ending certainly has me impatiently pining for book 2!

Interesting take on the genre
Format: Kindle
True rating: 3.25 ⭐️ I enjoyed the fresh take on the genre. The best way I could describe the setting and world is an apocalyptic dystopian version of Farie where vampires, fae, and angles struggle to survive in what is left of the world. It was definitely interesting throwing the academy/hunger games aspect into this world as well. Even though I guessed the final reveal early on in the book, I kept hoping I was wrong, and it would take a surprising turn. While the "plot twists" were a bit predictable to me, I still enjoyed the ride this book took me on. Another downfall for me was the plot holes in the world building... I.E. if society has fallen and the world is in the aftermath of war, how are there trains running around the world? Just to take young adults to the trials to get into the golden city? How is the train maintained, the tracks clear, etc? However, I did enjoy the FMC & MMC and thought they were fleshed out nicely. I also enjoyed the side characters but wish some were developed more like Ashalin (sp?). I do find myself rooting for the MCs to succeed and find happiness together, which is obviously an important aspect for romantasy. Overall, was this an earth-shattering, mind-bending, terrific piece of literature? No. But was it the worst thing I've read this year? Also, no. This book has, to me, the bones of a great read & just needs a bit more to push it from an alright book to a great book. Overall ratings: Plot- 3.5⭐️ World building 3⭐️ Spice 2.5 🌶🌶 Main characters 4 ⭐️ Supporting characters 3.5⭐️

great book
Format: Kindle
I am really excited to meet the author at the book retreat this month. I really enjoyed this world that she built and most of the female main character Huntress is so awesome. She goes through a lot in this book and the ending; wow! I wouldn't have even guessed. I highly recommend everyone to read this book. I have been so lucky this year that almost all the books I have read have been, so far, 5 out 5 stars.

Fallen for the Fallen Angel – A Guilty Pleasure Worth Every Page
Format: Kindle
There’s something deeply irresistible about a dark academia or trial-based setting, a brooding and arrogant fallen angel, and a fierce heroine with enough sass to go toe-to-toe with him. Wings So Wicked is exactly that kind of book—and I devoured it in just a couple of days. To be fair, the plot isn’t groundbreaking. If you’re looking for something fresh and innovative in terms of storyline, this might not be it. But if your reader heart beats faster at the mere mention of enemies-to-lovers, jealousy-fueled banter, magical trials, betrayals, and forbidden tension—you’ll feel right at home. It’s like catnip for those of us with this particular weakness. The chemistry between the leads could have used a slightly slower burn to make the tension sizzle longer, but I still found myself completely invested in their dynamic. There are moments and phrases that feel a bit cheesy or underdeveloped, but honestly? I didn’t care. The vibes were exactly what I wanted. This book isn’t trying to reinvent the genre—it’s here to give readers like me what we crave: high-stakes magical drama, angsty romance, and the thrill of watching a badass girl and her brooding counterpart clash and spark. If that sounds like your kind of story, Wings So Wicked will hit the mark. Here’s hoping Book 2 turns up the heat and keeps the magic alive.

my new favorite book
Format: Kindle
Ok so I never write reviews but this book was so good I felt the need to write this. Firstly your introduced to Huntyr you see her closed off hard core badass than towards the end you see the most subtle change and growth it’s amazing and the enemies to friends to lovers was just perfect, AND THE TWIST AT THE END GOT ME GOOD! You see one spicy scene the whole book but it doesn’t even MATTER BECAUSE THE BOOK WAS THAT GOOD. I’ve read 85 books in 2023-2024 so far and I’m pround to say this is my all time favorite. I’m so excited to read more of Emily Blackwoods books, this was my first time reading one of hers and I’m glad I did because HOLY!! Well done Emily well done
