All-round air ventilation keeps the ride cool – choose the Plus version for additional mesh and even more breathability. Five recline positions provide tailored comfort in either direction, for tiny newborns and fully-grown four-year-olds alike. 360° of comfort and safety for their first four years: the Sirona Gi i-Size.

Installation with base: Pay attention to the i-Size logo. If a vehicle seat is marked with this logo, it is suitable for use with all i-Size child seats and will therefore not appear in our list of compatible vehicles. If your vehicle does not have an i-Size seat, please check the compatibility of your vehicle. If your vehicle is not displayed, please contact our customer service team.

Up to 50% higher safety levels*

Rear-facing is one of the safest ways to travel. In the critical first moments of a front impact, the child's body is pushed against the padded car seat shell, minimizing movement and reducing the 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 comfortable rear-facing travel until your child weighs 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 to face the car door and get your child onboard. You avoid back strain, while your child stays comfortable in any recline position.

Optimal breathability

Comfort in any season. All-round air ventilation lets air flow through channels in the car seat, carrying away heat and helping avoid a sweaty ride for your little one. The Plus version also includes mesh fabric that increases breathability up to six times compared to regular fabrics.

Side-protection

Integrated 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

Find the ideal recline setting, whether your little one is a newborn or a growing child. Five positions are available in both riding directions – and in the boarding position, too. And when your child falls asleep, you can recline the seat with one hand, letting them dream that little bit longer.

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 only one hand is required.

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. Switching from rear to forward-facing is just as easy.

Straightforward installation and anchorage

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. Both provide stability and extra safety. Visual indicators help you confirm the seat is ready to protect.

SMALL! Don’t waste your money!
Size: 1 Fl Oz (Pack of 1)
I should’ve looked closer when purchasing because this is a super small sample size that isn’t even as big as the travel size and yet I paid as much for it as a regular size. What a joke! The product itself is great but I would’ve never ordered this size if I’d known it was going to be sooooo small. What a ripoff!

Obsessed. Soothing, effective, fragrance-free, incredibly healing
Style: Tolerance Daily Foaming Facial Cleanser
I’ve been loving this so much I bought a second bottle after a few days of using it. It has all the skin soothing benefits of the tolerance lotion cleanser, but it’s also a really great cleanser. It’s almost not noticeable how good it is at cleansing because your skin doesn’t feel stripped after, but it takes things off really quickly. I was worried because it doesn’t foam a lot and it feels so nurturing — much like the tolerance lotion cleanser (which I use as a second cleanse when my skin needs a few days to recover from something like a derm office treatment) — but when I wash again with my favorite HG cleanser nothing extra comes off, and I tested it twice on waterproof eyeliner that I’d swiped on my forearm for an hour or so, the eyeliner dissolved and wiped off with two or three gentle swipes. It has a very emollient texture, so when you rub it against your skin it slips so easily you don’t realize it’s dissolving and taking things away because there is no friction. So it’s great at taking off makeup, it’s AMAZING at cleaning makeup brushes, and IT DOES NOT BURN MY EYES AT ALL. Also, it is FRAGRANCE-FREE… before I bought it I read a review complaining about smelling a citrus fragrance, that person either has some sort of brain tumor or something spilled on their bottle when it was in a warehouse because this is definitely a fragrance-free product. Prior to trying this, I had tried another cleanser that gave me weird acne hives all over my chest (never happened to me before) and I was struggling to heal the acne and the irritation. I noticed an immediate difference when I started using the tolerance cleanser on it; the fresh redness went away, the acne started healing, and the post-inflammatory hyperpigmentation has been healing fast. So I’ve been using this on my body as well and it’s soothing and moisturizing in all the places where other things have been drying. I have mild rosacea and I hadn’t realized how irritated my skin was from the last thing I’d tried until after 5 days or so of using this my skin tone looked much more even and the stubborn PIH I have from a two-zit hormonal breakout a month ago finally looked dramatically lighter (as recently as the week before, I’d needed to cover them with high-coverage concealer). Because this doesn’t foam much, some people might not realize how well it’s cleaning… I encourage you to judge it based on how your skin looks and feels. Since it is very emollient though, I do think it’s important to use it with a face wash scrubber or washcloth just to ensure you’re getting some mild mechanical exfoliation and clearing away skin cells that could be trapping stuff in your pores. For this reason, I do wash my face with this twice so the first wash can get off makeup/debris/oil and then the second wash can really penetrate and clean my skin.

No Scent and Gentle
Style: Tolerance Daily Foaming Facial Cleanser
I broke out in a case of Perioral Dermatitis recently and bought this product to help before I could see my doctor. Avene Tolerance facial cleanser has no scent and is very gentle on my skin. It didn’t burn when washing with this product, and even helped to slough off the dead skin around my lips. My face feels clean, not dry. I am still going to see my doc to get an RX for the inflammation, but I do believe this product helped to alleviate the dryness and tightness of my skin and lips. I’ve used other Avene products and I’m very happy with them. Even though these products are more expensive, to me they are well worth the money because they are much more gentle on the skin than any other products I’ve used. I will buy this product again just because of the fact that it’s so gentle. PS: at the time of purchase for this product, I also bought Avene’s Tolerance Control Skin Recovery Cream (you don’t need to use a lot of this one on your entire face), and Avene’s Cicalfate for lips. Between these 3 products, my lips and skin feel a lot better (however, I will still see my doctor because I have Crohn’s Disease and Perioral Dermatitis is considered an extra-intestinal side effect of Crohn’s).

Gentle everyday cleanser!
Style: Tolerance Daily Foaming Facial Cleanser
My go to nightly cleanser! Gentle yet effective. Removes makeup without leaving any residue behind. Also does not dry out my skin or cause breakouts! I would say it’s more of a cream cleanser though. It does not really foam up. It’s a decent size bottle for the price. The pump dispenser is an added plus!

So gentle and moisturizing. Great for super sensitive skin.
Style: Tolerance Daily Foaming Facial Cleanser
This is so gentle and moisturizing. Does not irritate my skin in any way. My skin is super sensitive and I have atopic dermatitis, it has been the best cleanser I’ve used to date. I was using another one from this brand and it was fine but this is the one I will continually stick with from now on. Just hope they don’t change the formula.
