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.

Very nice at a nice price.
Color: White, Size: 35 Inch, Style: 2 Pack, Color: White, Size: 35 Inch, Style: 2 Pack
Very easy to mount on the wall. Very sturdy with about 10-12 lbs on each shelf. Only took about 15 minutes to hang each one.

Cat playground
Color: Black, Size: 35 Inch, Style: 3 Pack, Color: Black, Size: 35 Inch, Style: 3 Pack
Easy to install. Sturdy enough for 2 large rambunctious kitties to play on and look very nice. I was working on a vertical play space for the cats and since these come in many sizes it worked great. I did add grip tape to some.

Not the best quality
Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack, Color: Rustic Brown, Size: 35 Inch, Style: 2 Pack
The shelving unit was not as I had expected. It arrived damaged. The damage is on the under side though. They are hollow and not hardwood as I had expected. Save your money if you want something of good quality. These are like 3 pieces of pressed wood glued together. They are space saving and look great in my space. The mounting hardware it comes with was plenty enough to hang these but make sure you hang them in the studs if at all possible. Assembly was simple. It does come with a micro level. Which a kid or pet could accidentally swallow. It’s like pill capsule sized so just be careful when opening the package.

Loving these
Color: Wooden Black
Two (Med and Large) will safely hold a larger electric power strip. The Small is on my desk holding odd items and bits that should be stored upright. They're so simple to use too! I love the colored Velcro strips that come with them and the plastic cable guides. I honestly didn't know they were included so that was a BONUS! It definitely helped sort my cables and power cords for my work station as well as my crafting station. Keeping them safely out of the way means my robot vacuum can run without any complications. The wood tops actually blend with the floors making them less visible. If I needed more I would certainly get more! I may buy more for gifting.

No More Messy Looking Cords Everywhere
Color: Wooden Black
These are such a great find! My office, bedroom and living room look so much cleaner now! The sizes were just right to meet our needs. The colors matched our decor and the cords no longer stick out like a sore thumb. It was easy to get the power strip and the cords organized inside the boxes and using these is just the perfect solution to a messy problem. Highly recommended!
