Cybex Sirona Gi i-Size 360 Car Seat with Isofix Base – Magic Black
The latest car seat in the 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 defence 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.
Five recline positions are available in either direction to ensure ultimate comfort for your child, whether they’re a tiny newborn or a fully-grown four-year-old (newborn inlay accessory sold separately).
Comfort and safety for their first four years with the Sirona Gi i-Size.
*compared to the same seat forward-facing in a frontal crash. Result of internal testing using 2022 ADAC frontal crash test criteria.
Product Features:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

Love These Balls
Color: H) 2.5" 3-Pack (Beef), Color: H) 2.5" 3-Pack (Beef)
These are great balls. My Border Collie can destroy a tennis ball in a couple of hours and the Kong brand ball is heavier than I like to play with in the house. These balls hold up to her biting and chewing but are lite weight and softer for bouncing off the walls.

Seems durable - but the scent is not the best
Color: B) 3" 2-Pack (Bacon)
I don't know if I'd call the scent of this "bacon," more like rubber with a hint of bacon. It's very strong. I gave my dog one of the balls & put one in a cabinet where I keep his treats & a few other unrelated odds & ends. I now hold my breath when I open that cabinet b/c good lord, the smell. I'm tempted to just give that one to the dog too, just because it'll air out eventually & then everything else in that cabinet won't smell bad.
My dog feels so-so about it. He'll briefly chase after it & chew on it, but loses interest in it pretty fast. My rather hyperactive cat also plays with it from time to time, as he seems to have more interest in most dog toys than the dog these days, so there's that. (Then again, he thinks a wide variety of random items around the house are loads of fun to toss about, so it's possible his opinion is to be taken with a grain of salt. Between the brief periods of one of these balls being chewed on & clawed at, it's stayed completely intact. I think if you have a dog who simply likes to play fetch or chew on rubber balls in general, this one would stand up to the task. But if you're expecting it to be greeted with the enthusiasm as a bacon grease covered ball might be - I'd adjust your expectations.

My dogs favorite toy so far in two years
Color: C) 4" 2-Pack (Bacon)
I use this with my medium sized dog. These are large for him but that's what I want so I don't ever have to think about them being too small or a swallow hazard. He has been through A LOT OF TOYS in the last couple years, but nothing, NOTHING has he loved as much as these.
His favorite used to be squeaker balls. Then his favorite was crackle balls. But he will gladly ignore both for this one. I don't know if it's the bacon flavor or what, but he go nuts for it.

Durable Rubber Bone Toy for Aggressive Chewers
I got this rubber bone chew toy in purple (size large) for my dog, and it's been a solid addition to his toy rotation.
What I Liked:
The bacon flavor is a huge hit. My dog was immediately interested in this toy and goes back to it regularly, which speaks to how appealing the scent is to him. The natural rubber material is tough and has held up well to his aggressive chewing - it's designed for heavy chewers and delivers on that promise. The textured surface is great for dental health. I can see how it helps clean his teeth as he chews, and the grooves are deep enough that you could add dog toothpaste for extra cleaning power. It's a functional toy that serves multiple purposes beyond just entertainment.
The rubber material is softer than hard nylon toys, which gives me peace of mind that it won't damage his teeth during extended chewing sessions. It's still plenty durable but has some give to it that makes it safer. This toy genuinely keeps him busy and engaged. It helps redirect his chewing instincts away from furniture and other household items, and it seems to help with anxiety when I need to leave him alone for a bit. At $8.99 (down from $15.99), this is an excellent value for a durable, functional chew toy.
What Could Be Improved:
While it's marketed for all sizes from small to large breeds, I think it works best for medium to large dogs. Small dogs might find the large size a bit cumbersome. The bacon scent is strong initially, but it will fade over time with use and cleaning. Also, we all know it's a little... interesting looking haha.
Overall:
This is a high-quality, durable chew toy perfect for aggressive chewers. The bacon flavor, dental benefits, and tough construction make it a winner. It keeps dogs engaged, helps maintain dental hygiene, and redirects destructive chewing behaviors. At under $9 (well, it is right now, at least), it's a great value and makes an excellent gift for any dog owner dealing with a heavy chewer. Highly recommended.

The Purple Power Chew My Dog Thinks Is His Life’s Mission
I bought this purple rubber bone hoping it would survive longer than the usual 10 minutes my dog needs to destroy a “durable” toy. Shockingly, this one is still alive and thriving. Honestly, I think it might outlive me.
The material is tough enough for aggressive chewers, but still bouncy and fun, which means my dog is entertained AND my furniture gets a break. It’s the perfect size for medium to large dogs, and it keeps mine busy like he’s working an important full-time job.
He tosses it, chases it, gnaws on it with total devotion… and somehow it barely shows a scratch. The purple color is a bonus, easy to spot in the yard, and it makes him look very fashionable in his ferocious-chewer era.
If your dog believes every toy is a challenge to conquer, this chew toy just might be the worthy opponent they’ve been waiting for. 💜🐶
