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.

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.

Deserves more Stars
Size: Queen
I was very hesitant to make a pillow purchase off Amazon. Turns out it’s the very best purchase! I had chronic neck issues the chiropractor couldn’t resolve. It was the first time, I had an unsolvable issue. I finally decided to spend the money and buy new pillows. My neck issue was 95% resolved the next morning. I’m not kidding! It’s now 100% resolved after a very short period of time. They are a wonderful gift to myself.! quality is top-notch. The support is fantastic. They adjustability is phenomenal and you can adjust the firmness because they give you extra foam. They’re completely worth every penny. I’m 61 years old, 100 pounds and very active. Waking up with neck strain was horrible.

I Hit It With the Dryer and It Became a Real Pillow!
Size: Queen
This DreamyBlue Moon Pillow made a much better first impression than I expected. Out of the package it looked like it needed a pep talk, so I threw it in the dryer to fluff it up and it came back with purpose. Just full on BAM. Pillow achieved. The shape is one of the best parts. It actually feels like a pillow that wants to do its job right. Not too weird, not awkwardly bulky, not one of those ones that looks promising until you lay down and realize your head is now parked on a bag of chopped foam and bad decisions. I also really liked being able to customize it. That part matters more than people think. Pillows are weirdly personal, and most of them give you exactly one option: deal with it. This one lets you adjust the fill until it actually feels right, which is a whole lot better than waking up annoyed and pretending it is fine. And for anyone wondering, mine did not have any weird smell. No chemical funk. No “maybe this needs to live on the porch for a day” situation. It just fluffed up, felt good, and got to work. Overall, this has been a solid win. Comfortable shape, easy to adjust, and none of the usual nonsense. Which, for a pillow, is honestly a strong performance.

Soft yet supportive
Size: Queen
I have been through 4 other pillows in the last year trying to find one that supports but isn't too firm. I gave this one a shot and am really loving it. It's soft, comfortable, supports without hurting my neck or shoulder. I am short so some pillows are too high for me. I'm mainly a siide sleeper, this pillow is great as I can place my head anywhere not just middle of very end like the other pillows I was trying. I can sink into it a little yet still have support and it doesn't crush down. It comes with more filler but haven't needed it. I put it in the dryer on ultra delicate when I first got it and it fluffed nicely. Very happy with this product as I am now getting more sleep.

Absolutely in love with this pillow!
Size: King, Size: King
I’m so excited about this purchase — this pillow turned out to be amazing! I’m a side sleeper most of the time, and the way the edges are designed makes it incredibly comfortable and supportive. What really surprised me is that even when I slept on my back (which I normally don’t like), I felt super comfortable. I actually woke up still lying on my back — and that never happens! I know it’s healthier to sleep that way, so I’m really happy about that and hope it becomes a new habit. Before this, I tried a few regular memory foam pillows, but they always felt too firm and my neck would get tired. This one, with the shredded memory foam, is so soft and cozy — it molds perfectly without feeling lumpy. The King size is perfect too — my little Pomeranian loves to rest his tiny head next to mine on the pillow. I don’t know why he does that, but it’s adorable. And I have to mention the packaging — the box was so high-quality and beautifully made that I just couldn’t throw it away. I’m definitely keeping it to store something in. Overall, I’m super happy with this pillow and will be ordering a second one soon. I only got one to test it out, but now I’m totally convinced. Thank you for such an awesome product!
