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.

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.

A Powerful Anxiolytic and Sleep-Enhancer
Size: 30 Count (Pack of 1)
I have tried a plethora of non-pharmaceutical anxiolytics, and I can say that CalmAid is by far the most effective. For me, the effects are comparable to a low dose of Ativan, but without the drugged feeling. Here are the main things I notice: -Relaxed heartbeat. My heartbeat is usually very pronounced, but when I take lavender, it calms down dramatically. -Quieter thoughts. I don't know how to describe this except to say that the "volume" of my thoughts is turned way down on lavender. -Tremendous sense of calm. It's very hard to get upset or agitated or anxious while under lavender's influence. -Improved sleep. I've suffered from horrible insomnia for a long time, and lavender is one of the only remedies that's had a noticeable effect. It doesn't make me drowsy per se, but it makes me so calm and relaxed that sleeping is easier. However, there are some "side effects" (I use the term loosely) to be aware of when using this: -Reduced energy. I suspect this is just the lavender calming my stress response and revealing fatigue that's already present to some degree, but it's worth noting. As I mentioned, lavender doesn't make me tired, but it makes me just want to kick back and chill rather than doing anything very active or exciting. -Reduced motivation. Tying into the above, when using lavender I would often rather relax and watch a movie or read instead of getting work done. This is, I suspect, the dark side to being incredibly calm, whether it's lavender or something else making you that way. When you're calm, nothing seems to matter that much, including work. Ergo, you have less motivation. I think a certain amount of anxiety is healthy for optimal motivation, and lavender does away with that. -For these reasons, I don't consider lavender an optimal anxiolytic for social anxiety, because energy and motivation are so important in social situations. I suffer from social anxiety, and have used lavender to deal with this at times, and though it does make me less anxious, it also makes me less social. I'd recommend something more like phenibut for social situations. Despite these limitations, I still consider this an essential component in my anti-anxiety toolkit. I just try not to use it too often. Also, it's worth noting that human studies on lavender are somewhat lacking, and without more data, we don't know what the long-term effects of using it are. As with any drug (and I do consider this a drug), I think it should be used as little as possible. I would, however, much rather use this than a pharmaceutical anxiety medication. A final note, on when to take it: I've found the best time to be 30 minutes before bed, on an empty stomach. The effects are more dramatic when taken well away from food, and if you take it before bed, you get the sleep-enhancing effects immediately, and the anxiolytic effects all throughout the next day (it lasts a looong time).

Effective, but gave me a headache
Size: 30 Count (Pack of 1)
I did and do like these. I find it takes the edge off my anxiety. Oddly enough, they give me a headache the next morning. I tried only taking one pill at bedtime (instead of a second one halfway through the night); I made sure it wasn’t dehydration; I took electrolyte solution with it. I’ve pretty much eliminated anything else that a headache could’ve been caused by that I can think of. They work well enough for me that on some nights it’s going to be toss up and I will still take it. But it’s kind of a drag knowing that something natural that works has a residual headache the next morning.

Day 1 and A Week ish Later
Size: 30 Count (Pack of 1)
I was taking Olly Stress Relief gummies for a while to control anxiety, hyperactivity and racing thoughts, and they worked great. Recently I noticed that they were becoming a lot less effective and started searching for alternatives. This was my first choice and I've only used it this morning. Took one pill. So far I have noticed a lighter mood, lack of racing thoughts, and an overall feeling of being slowed down. I can focus on conversations better, and it slightly enhanced my ability to taste, flavors seem more vibrant.. I am a bit more "lazy feeling" as others mentioned, and I did get the lavender burps. They're not horribly obnoxious for me, just a bit different. Burps lasted maybe half an hour. So far I like it. Edit: it's been over a week now. The first few days I dealt with random headaches on and off, but did get benefits as stated above. After my body adjusted I stopped having the headaches and the "lazy" feeling. The lavender burps are still a thing and so is short term lavender breath right after taking a pill. You can describe it like a light lingering, kinda like toothpaste has a minty aftertaste, but lavender instead. For the most part I would still say it helps. It does not hit as hard as the first few days, but it is helping somewhat. Benefits for me: Less overstimulation in public, better ability to relax after work, anxiety is more "inconvenience", easier to focus, deeper sleep, less irritability. Cons for me: Short term lavender breath, vivid and unusual dreams, 2-3 day initial adjustment period for unpleasant side effects. What I'm doing: Taking one pill around 7-7:30pm daily with lots of water. Taking late to sleep off any potential unpleasant initial effects, and get better sleep.

Finally, a Calm That Feela Natural
Size: 90 Count (Pack of 1)
I've tried a lot of "calm" supplements over the years, and Nature's Way Calm Aid is one of the few I've actuallt reordered. I started taking it during a stressful stretch at work when my mind wouldn't slow down at night. Very shortly after taking it I felt more settled and less on edge. it takes the edge off without making me feel like I'm dragging through the day. The softgels are small and easy to swallow with no weird aftertaste. This has been a real game changer for me. If you're looking for something subtle but effective to help you stay calm and focused, CalAid is definitely worth trying.

Great Addition to My Daily Routine
Size: 16 Ounce (Pack of 1)
Excellent Quality MCT Oil — Great Addition to My Daily Routine I purchased this MCT Oil and have been very pleased with it. It is light, smooth, and easy to add to my daily routine without changing the taste of my food or drinks. I especially like that it mixes well in coffee, tea, smoothies, and even oatmeal. It does not have a strong flavor or unpleasant aftertaste, which makes it very convenient to use every day. Overall, I would definitely recommend this MCT Oil to anyone looking for an easy way to add healthy fats to their diet. It is high quality, easy to use, and a great value for the price. I would purchase it again.
