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.

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.

reviewing 2 years later, still in love with this blanket!
Color: Grey, Size: Queen (88" X 88")
i've had this blanket for almost two years - i bought it july 5th, 2024. i should have wrote this review much sooner, there hasn't been a single day in the past almost two years of owning this blanket that i have regretted getting it, it is an absolute must have for hot sleepers. it isn't constantly cold, but it is cold to the touch and you'll feel how cold it is as you move around. it mainly helps regulate your body temperature throughout the night. i've washed and dried this blanket so many times (with cold water and low heat as directed) and it still maintains the cooling effect the same as the first day i got it, it also hasn't torn or ripped anywhere. whenever i travel i always miss this blanket and i am so happy when i come back home because i have my blanket again, it makes a huge difference for my quality of sleep. i'm genuinely considering only packing this blanket and nothing else the next time i travel. also, despite helping me stay cool throughout the night, it's very comfortable and has a nice thickness and weight to it, so i don't feel like i have to sleep with a paper thin sheet for the same effect. what i like to do during winter (and i'm talking actual winter, like wind chill in the negatives) is add a thicker blanket on top to get some extra layering, but still have the cooling effect. 1000/10 i absolutely recommend this blanket if you're a hot sleeper and honestly this company in general, bedsure makes some really good stuff! this was a really good investment for me, yes it's an expensive blanket but it pays off for sure. as a goth person i do wish they had some darker colors for this blanket, ideally black, but when this blanket has helped me this much with my sleep? i took the loss in that aspect, and if the color was the only loss i think that says a lot! thank you bedsure for helping me get good sleep :)

Magic!
Color: Grey, Size: King (102" X 90")
This comforter is super soft. Almost silky feeling. Very easy to wash and dry. It does as advertised. It keeps me super cool. I love it so much that I bought a second one for my camp. It is so cool to the touch. The fit is true to size. It's not thick but not too thin either.

Bought this for my son and just ordered me one
Color: Grey, Size: Queen (88" X 88")
My son's college apartment runs warm (that is probably because college students trying to save money) so we decided to order him this cooling comforter. I have been wanting one since entering menopause but never bought one for myself (the things we will do for our kids but not ourselves) so when his came in I told him I was going to use it to see if I liked it and if it helped with the night sweats until we met up to give it to him...those three nights of me using it were enough for me to want one. This is a game changer! It is thin like a blanket so we removed the flat sheet and put this under our regular comforter. My husband needs the thickness of our regular comforter because he says I freeze him out at night. This 'comforter' is so soft, fits the bed great (as a blanket or comforter), and is truly cooling. Now, that's not to say I haven't woken up a little on the warm side but all I need to do is readjust to a cool spot under the blanket and I fall right back to sleep. The grey is very light but it is washable as needed.
