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.

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.

Good option
Color: White, Size: Body(Pack of 1)
I’ve been using the ACCURATEX Full Body Pillow for Adults – Hybrid Shredded Memory Foam for a few weeks now, and overall I’m really happy with it. The blend of shredded memory foam gives it a firm, supportive feel, but what I love most is that you can adjust the filling to get the exact firmness you want. Whether you prefer something more structured or slightly softer, it’s easy to customize by adding or removing foam. Comfort-wise, it’s definitely a step up from standard body pillows. It keeps its shape throughout the night and offers great support for side sleeping. That said, it is a bit firmer out of the box than I expected, which is why I’m giving it 4 stars instead of 5. If you’re looking for a body pillow that won’t go flat and lets you tweak the feel to your liking, this one is a solid choice.

Favorite pillow!!
Color: White, Size: Body(Pack of 1)
I honestly wasn’t expecting to love this pillow as much as I do. Buying pillows online always feels risky because you can’t actually feel them beforehand, but this ended up being one of the best blind buys I’ve made on Amazon. The quality is genuinely shocking for the price. It feels way more expensive than it is. It’s insanely comfortable, supportive without feeling stiff, and just has that “perfect” cozy feel. I have neck problems, so I’m really picky about pillows, and this one somehow manages to be the perfect balance. It’s supportive without being stiff or overstuffed, but also not too flat where your neck feels unsupported. It has that perfect “sink in but still supportive” feel that’s hard to find. I loved the body pillow version so much that less than a week later I’m already ordering the regular pillow version too. Easily 5 stars from me!!

Probably going to replace all the pillows in the house with these
Color: White, Size: King (Pack of 2)
These pillows are just about perfect. They have to be the best pillow for the money out there at least. I didn't even know that this kind of pillow existed but was asking Google Gemini what kind of pillow would best suit my list of needs and this is what we came up with. - High loft for comfortable side sleeping, but can be reduced by removing foam to be less high - Gives initially, but stays at that new same thickness throughout the night b/c it's memory foam chunks - Doesn't feel lumpy because it has the 1cm outer pillow layer that covers the memory foam pieces I'm 6/3" 210lbs and after a couple nights of adjusting I found that removing about 1 gallon ziploc of foam chunks from each pillow was about perfect. I saved the foam in ziplocs in case I change my mind. They come REALLY loaded at first so should fit literally anyone with some adjusting. It was definitely too big the first two nights until I got it just right.

Hard As Rock When Cold
Color: White, Size: Standard (Pack of 2)
These are good pillows except they get hard as a rock when the temps go below 65F and take 10-20 minutes to warm up at bedtime. Not ideal where the winters are colder or for someone with cervical spine issues.

LUXURIOUS, just like it says
Color: White, Size: Queen (Pack of 2)
I used My Pillows for years which needed constant fluffing throughout the night until they just became useless. Since they became useless, I would always wake in the middle of the night with terrible headaches and my head would be sore all over, throbbing like a boil. I couldn’t stand anything to touch my any part of my head while these headaches occurred. One night almost a week ago I was awake in pain and couldn’t sleep. I started googling for a solution, a pillow that would support a human head, basically a bowling ball. After several products which kept sending me to Amazon, I stumbled upon this pillow. I read all of the reviews. Many compared it to a “luxurious hotel pillow”. So I waited and got them within less than 48 hours. It was a thin box so I wasn’t expecting much. They were vacuum sealed, I opened them and allowed about an hour for them to fully expand. They were comprised of memory foam and down alternative like “luxurious hotel pillows”. They were heavy too. I tried to fluff it for maximum feel. It was extremely firm and I wasn’t able to actually fluff or reform it in any manner really. I could feel the down alternative filling surrounding this semi hard center ( the memory foam I guess) and I fluffed as much as possible. I had difficulty getting it into my pillow case, which was fine to me. It just made me anticipate this perfect looking pillow. I had been suffering with these headaches due to inferior pillows, I couldn’t wait. I laid down and put my bowling ball head on it! It completely supported my head. I normally like my pillow to conform around my neck and shoulders to allow a straight alignment with my head. My head was slightly up, but hey this felt great!!! I could feel the down alternative filler cushioning my head with the firm memory foam in the middle. I could not wait to try it that night. Night comes and I’m excited to see if I can sleep through the night finally without waking with those terrible headaches. I slept almost all through the night except for going to the bathroom once!! And my head wasn’t hurting nor did it feel like a boil!! I was ecstatic to say the least. I know there are people just like me searching for relief. If you can tolerate a firm pillow you can’t go wrong with these pillows. You get two for a great price! I just wish I hadn’t wasted hundreds on My Pillows for all my bedrooms a few months ago. I will be replacing all the pillows in my home with these WONDERFUL pillows!!!
