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.

I’ve lived decades without this pillow… and I regret every single second!
I can’t even overstate how excited I am about this pillow. I’ve only had it for one night, but in that time, it’s completely changed my life. Literally — I sat on my bed with it all day just hugging it and marveling at how I survived adulthood (and procreation years!) without it. Physically, I’ve been more comfortable in the last 24 hours than I have been for years. And as a bonus, my dogs sleep up against me, which can produce a lot of pressure, but this pillow creates a perfect natural barrier. They seemed to respect it completely — for the first time in three years, I didn’t have a 50lb dog pressing on me all night. Total bliss. The U-shape supports you in all the right places — back, hips, knees, belly — and the velvet cover is soft, removable, and washable. Honestly, whether you’re pregnant or not, this pillow is a life-changing sleep upgrade. I have no idea how I ever lived without it.

Bumpy & lumpy.
This pregnancy pillow arrived in a surprisingly small box—about the size of a shoe box just a tad bigger—which honestly impressed me considering it’s a full-body U-shaped grey pillow. Once opened, I cut the plastic wrap and let it decompress for a full 24 hours as recommended. After placing it on my bed to check it out, I noticed the pillow felt lumpy throughout, almost like the filling needs to be manually shifted and positioned to where you want support. That part felt a bit odd and took some adjusting. The outer velvet cover is soft and pleasant to the touch, but unfortunately the pillow itself doesn’t feel very soft once inside the cover. Doesn't give the fully support that I wand and need. Overall, it does expand to full size and the cover is nice, but the uneven filling and firmness made it less comfortable than I expected for sleeping.

Finally a Cooling Blanket That Actually Works for Hot Sleepers
Size: Queen (90" * 90"), Color: Luxury Grey, Size: Queen (90" * 90"), Color: Luxury Grey
I first got to know this brand when they released their cooling pillow. At the time, I was very skeptical because I’ve tried many “cooling” pillows and pillowcases from other brands, and almost all of them failed to stay cool throughout the night. Surprisingly, this brand was the first one that actually worked for me. Going through menopause has been extremely difficult, especially dealing with the constant heat and night sweats. I kept thinking that if they could somehow use the same cooling technology in a blanket, it would be amazing — and they actually did it. This blanket has honestly been a lifesaver for me. One side has the cooling fabric while the other side feels more like a regular blanket, so you can switch depending on the temperature or season. I’ve been using a silk comforter before this, and while it was comfortable, it really didn’t help much with overheating at night. This cooling blanket made a noticeable difference almost immediately. What impressed me most is that the cooling effect doesn’t just disappear after a few minutes. It stays comfortably cool and lightweight through the night without feeling damp or overly thin. Since using it, I’ve actually been tracking improvements in my sleep using my WHOOP device, and over the past 20 days I’ve noticed my deep sleep readings improving consistently. The blanket also feels well made, soft, and lightweight without feeling cheap. For the quality and performance, I think the price is very fair, especially compared to other “cooling” bedding products that overpromise and underdeliver. If you struggle with hot sleeping, night sweats, or menopause-related heat issues, I would absolutely recommend giving this a try. It genuinely improved my sleep quality.

Great blanket for keeping cool, but doesn't magically defy physics.
Size: King(103“*90”), Color: Luxury Grey
This blanket is pretty awesome, and functions exactly as stated; however you might get the wrong impression from the image of the blanket in a the snowy mountains glowing blue as if its actively cooling. The blanket has two sides, the "cold" and "normal" side -- the cold side is the one that has the Q-max 0.45 effect, it actually feels cool to the touch. That being said, covering yourself with this blanket feels pretty similar to using a down blanket with a silk (or some cooler) fabric. It feels quite cool initially but eventually your body puts out enough heat and it "runs out" of cooling. Although this blanket doesn't magically actively generate cooling, its quite effective because it operates fundamentally differently from most blankets. Most blankets are engineered to keep you warm by trapping heat in; this blanket is explicitly designed to draw heat away from your body. As such, it is extremely effective if you use a fan or run the AC, because your body heat is drawn away from the top surface and the inner surface can "grab" and remove more heat. As you probably know, air is a great insulator so this blanket has to be making contact with your body to achieve the cooling effect. If you are familiar with the way "Under Armor" works, I believe this blanket uses a similar principle to keep you cool. This blanket is quite light weight and comfortable, with a very silky (polyester) feeling outer surface. I have not owned this for a year yet, but I'm quite confident that this blanket would be suitable for winter (in Southern California); except if you live in a snowy region. 5/5 for a somewhat high tech blanket that keeps you cool; its the best in cooling you can get without resorting to "active" cooled blankets such as ones with water circulation.

Fascinating product.
Size: Twin(90“ * 67”), Color: Luxury Grey
It is a nightly struggle. My wife is a hot sleeper. I am not. It’s resulted in more than one argument. One of us is usually left shivering or sweating. So when Amazon offered to send me this cooling blanket, I thought I would give it a try. I’m really glad that I did. This item arrived well packaged and in good condition. It is lightweight and made of a polyester type material. The stitching is strong. The first test was the washing machine. We washed it with cold water on the gentle cycle. We then line dried it. It held up fine. We have a king size bed, but I decided to get a twin sized blanket. I put a warm blanket on my side of the bed and the cooling blanket on her side of the bed. It worked brilliantly. I don’t know what the science is buying these blankets, but it really does lower your body temperature. The moment that you open the package and feel the blanket, you’ll realize that it has some sort of cooling gel inside of it or something that draws heat away from you. Suffice it to say that our first night with this product was one of the best nights sleep that both of us had. If you have a problem like this, I would definitely recommend this blanket as a viable solution. In terms of value, I understand that this is not cheap; however, ask yourself what the value is of a good nights sleep. Overall, I’m very pleased with the quality, design, and functionality of the cooling blanket. I would definitely recommend it.
