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.

Best Shampoo/Conditioner I Have Ever Used
Scent: Nettle, Scent: Nettle
I purchased the Nettle Shampoo in hopes of getting my hair back to health after frying it off with bleach. I used it for the first time today and it is my favorite thing I have ever purchased for my hair. The smell of this is divine. I am not a sweet gourmand fan and this is just the most fresh scent I ever smelt I think. It honestly smells like a high end salon shampoo/conditioner duo. That is my favorite part about this product. Second favorite is that it actually does work soooo well! I put in quite a bit of oils and hair care before washing my hair and all of those oils were removed without leaving any waxy greasy feel to my hair. I was concerned it wouldn’t come out because this shampoo is 99% lather free. But it worked SO GOOD! It doesn’t feel dried out and brittle either. It’s just perfect I can’t stress it enough. 10/10 I wish there were more way I can say how much I adore this product. I have very fine hair by the way and it doesn’t weigh it down. I will keep using this and will update in maybe a month with pictures! Here’s the update: I used the shampoo and conditioner for idk probably a month. I’m not really sure. BUT I still absolutely love it. In the pictures I am going to attach, you can see that I had a decent amount of growth (the hair from the root that looks gray). My hair is quite oily after other hair care products were added so that’s why it looks the way it does. One more thing, the shampoo is very drying on the scalp I have noticed a little bit of dandruff and itchiness right after washing but I believe my scalp is getting used to it now because it’s getting less and less noticeable after every use. Keep in mind my hair had been chemically treated during the first week of use multiple times including bleach and box dye so that’s probably why it was irritated. I still absolutely adore the scent and the way it leaves my hair feeling light and clean and shiny and SOFTTT!

Great product, poorly designed bottles.
Scent: Onion Unscented
I like this product! However, the bottles are heavy, bulky and awkward, what a waste of plastic. The design is poor. The conditioner top was broken, and the product was so thick it was very hard to try and get out of the unyielding bottle when I unscrewed it. Had to ask for a replacement. But it smells great and leaves my hair very soft. I had gotten one for my mother (87) but the bottle was a little much for her, too bad. There's less in it than what it looks like, as it has an inner, smaller container. A lot of trouble and cost to save a small amount of product.

Great product for damaged bleached hair
Scent: Keratin
Great shampoo and conditioner. Smooths the frizzy ends. I bleach my hair and I am unhappy that this product appears to have washed or altered the toner. I have platinum bleached hair and I put a pale blonde toner on it. I waited 4 days after I bleached and toned my hair to use your product and the end result was yellow hair not that beautiful pale blonde color. I will play around with purple shampoo and your product to see if I can find a happy medium because I do love the silky feeling on my damaged over-processed hair. Thanks for developing such a wonderful product for damaged hair

Shiny Hair? Yes please
Scent: Onion Unscented
I have used this product just a few times since buying it. It made my hair shiny and smooth. Very minimal frizz. I bought it after doing research on how women helped their hair before all these hair products came out and Onion water was one of the top answers. After believing that I wanted onion smell in my hair, I came across this product and it actually smells SO NICE. After blow drying my hair, my hair was fuller and bouncier. I saw a difference right away. I have seen less hair in my shower drain and I honestly couldn't be happier with this combo.

Excellent product at a very fair price
Scent: Caffeine
I have been using the caffeine version of this shampoo and conditioner for a little over three months. I like to give a new shampoo and conditioner about three months before concluding if it’s a hit or a miss. Originally, I was using the biotin version of this shampoo for approximately two years and was very happy with the results. I needed to reorder, so I was looking over the other options in this same brand. This brand is considered to be a good quality product. I did do a bit of research before originally purchasing the biotin version. The biotin version is a lightweight product that did not weigh my hair down with build up over several uses. I ended up needing to use a clarifying shampoo only about once a month, as opposed to once every week. I have very fine, thin hair and a lot of products I have tried over the years have not worked for me because of the heaviness that leaves my hair flat. I did not have this result with the Bellisso Biotin shampoo. Bellisso is very well priced, and in my opinion, is comparable to more expensive salon products. I do like to try new things, so trying a different version of a brand that I was already happy with seemed like it didn’t come with much risk. Comparing the two versions, biotin vs caffeine: The biotin option worked very well on my fine, thin hair. The shampoo had a bit of a lower amount of foaming, but it did get my hair clean. The biotin conditioner also worked well, and was easy to rinse out and did not leave a residue on my hair. The caffeine version is very different than the biotin version, but neither in a good way or a bad way. Just different. I noticed that much less product of the caffeine shampoo and conditioner is needed to get the job done. The amount of product needed is probably highly dependent on your particular hair, so keep in mind, I probably have less hair than most people. The shampoo foams ALOT. I didn’t mind this at all. Per the instructions on the bottle, you are supposed to apply and massage your scalp and rinse after 2-3 minutes so the caffeine can be absorbed into your scalp, so having that extra foaming helps. This is meant to stimulate circulation in the scalp, and promote hair growth. If you are the girl that is always in a hurry, this is probably not the version of this shampoo for you :) The caffeine conditioner goes a very long way, so best to start with half as much as you normally use and go from there. All in all, I’m happy with both versions and I would definitely consider trying another version of this brand. I would highly recommend this brand in whichever version suits your personal hair type and needs. The price is right, as is the quality.
