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.

CYBEX were awarded Which? Baby and Child Brand of the Year in 2024!

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.

Durable and a Favorite!
Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large, Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
I *was* gonna hide them for a later date because they are great for keeping them busy and quiet! But the Amazon box got delivered and my Pittie, Whiskey, was very excited about it... that girl's got a great nose! Through a cardboard box, a sealed bag, and shrink wrap, she knew the best filled bones were in there! She chose the beef one. Otto, my Heinz-57, chose the peanut butter. The bacon and cheese will act as mediator so when they steal and switch, there's always a 3rd bone to keep the peace. These Pawstruck bones don't splinter like the Ol' Roy ones from Walmart (see photo, Ol' Roy is the darker one). Sure, they can manage to break off a few dull, tiny bone chips, but nothing that will hurt them, even if swallowed. Which, in a way is good; hard to break teeth if the bone gives just right. Whiskey is a mega power chewer and can destroy just about anything, but these hold up quite well and don't cause any gastrointestinal upset. The dogs absolutely love them! I also never notice any smell or any significant mess. Very heavy duty and thick, great large size so they really have to work on them. I also like the filling ingredients much better than the corn meal and various fats seen in others.

4 Paws up! My dogs LOVE them
Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large, Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
I have 2 large dogs who LOVE THESE. A Great Pyrenees mix who’s a skinny 80lbs and a lab/terrier mix who’s a chunky 50lbs. They both love bones and can REALLY chew through them quickly so I’m really picky about what I buy them. Here is what is important to me and how I rate and choose bones. These are my comments on this bone set specifically: Do they break/splinter? -They don’t splinter, I have seen smaller pieces that have broken off and when the bone gets down to the end (but this is normal with bones) at which point those pieces can be thrown away. I have never had an issue with them choking, being too small or hurting my dogs though and they are aggressive chewers so I could see this happening with some dogs and never happening with others. 4/5 stars for this. Do they smell/leave stains on the carpet? -Nope! No odor and they actually leave my dogs breath smelling better and their teeth cleaner! 5/5 stars Does it upset my dog’s stomach? (My bigger guy can’t tolerate a LOT of things, he vomits often and also gets diarrhea if he eats the “wrong” thing so I have to be very cautious.) -NOT at all! No upset tummies. This is always very, very important to me. Make sure you have lots of water nearby for your pups though, these will make them very thirsty. 5/5 stars Do they hurt my dogs tongue, mouth or teeth? -Nope, no issues with this. They’re able to gnaw into these aggressively without hurting themselves. 5/5 stars Are they gone in 2 seconds? -No! I’m always worried the “stuffed” bones will be left in the dust after the stuffing is all gone but my dogs will still keep chewing on these after the stuffing is gone. They still enjoy the bones and they last for quite some time, weeks at minimum. I can also stick some peanut butter or other treats back in the middle after they get the original stuffing all out of them to “reuse” them if it seems like they’re getting a little bored with them. 5/5 stars Do my dogs ACTUALLY LIKE THEM? -They love them. 5/5 stars Price? -Great and totally affordable. $20 for 3 of them.. so less than $7/bone. This is comparable to a bone from the pet store and these last a lot longer than something you would find there in the “fresh” grocery-store-like-section of the pet stores. I’m an avid review reader, especially when it comes to items for my fur babies because I want the best for them. I truly love these bones and will keep buying them. I will continue to buy these!

⭐️⭐️⭐️⭐️ Finally Found a Long-Lasting Bone That Actually Keeps My Dog Busy
Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
I’ve tried a lot of filled bones and chew treats over the years, and most fall into two categories: gone in 5 minutes, or upset stomach later. These filled beef shank bones hit the sweet spot. The bone itself is thick, dense, and real, not a thin, brittle shell. My medium-large dog is an aggressive chewer, and this keeps him occupied for a solid 30–45 minutes working on the filling, then even longer gnawing on the bone afterward. The filling smells fresh and appetizing (not rancid or overly greasy), and my dog goes crazy for it. We’ve tried the cheese-style and peanut butter–style fillings, and both were a big hit. No crumbly mess, no weird residue, and no digestive issues so far. What I really appreciate is that these feel safer than many cheaper alternatives. The edges don’t splinter, and the bone wears down gradually instead of cracking. Why I’ll keep buying these: • Long-lasting even for power chewers • Real beef shank bone, not pressed junk • Filling dogs actually care about • Helps with boredom and anxiety • Good value compared to pet store brands Minor cons: • Can get a little smelly after heavy chewing • I supervise and take it away when it gets small (as with any bone) If you’re tired of wasting money on chews that disappear in minutes, these are a fantastic upgrade. My dog is obsessed, and I finally feel good about what I’m giving him.

Best bones out there
Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
These are the best bones I’ve ever bought. I have a lab puppy and as you can imagine most bones don’t last long around here, but this one keeps him entertained for days.
