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.

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.

Comparable to Major Name Brands in price and quality
Size: Newborn (30 Count)
Good value for the price , comparable in value and quality of major name brands. Visually attractive and detailed product description on packaging. Newborn size package is very small and well packaged for easy storage. Diapers are made to fit comfortably to newborns body and manufactured to wick moisture into the diaper away from babies skin and so not to leak. They absorb a fairly good amount of liquid with no problems. The adhesive tabs stick well and do not come lose.

Lifesavers for sensitive skin!
Size: Size 6 (108 Count)
These are the only diapers we love after trying countless other brands. We struggled with so many issues, from diapers that felt cheaply made and rough, to constant leaks, or scents that caused horrible breakouts on my son’s sensitive skin. The Mama Bear Gentle Touch diapers are the first ones I have found that are truly soft, completely leakproof for us, and do not cause any irritation. They are lifesavers, and it is a genuine nightmare when we run out. They perform great overnight with no leaks, and they hold up well during active daytime play. We do get a few leaks, but it’s when my son chugs the water. I don’t think any diaper is saving that. The fit is consistent, the tabs are secure but still stretchy, and buying the bulk pack is a good value. If you have a child with very sensitive skin, I highly recommend giving these a try.

Wish we had these diapers with my first 3
Size: Newborn (120 Count), Size: Newborn (120 Count)
I am 39 been married 22 years and I have 4 kids. We have always had our kids seperated over the years and I have always used Luv's with my first 3 all other diapers leaked badly, never lasted long or gave the kids rashes. Luv's worked a little better on leaks at night none of the these diaper prevented leaks on sheets and bed while sleeping u always had to change there diapers multiple times a c there skin was always wet. With my first 3 kids we did not have the choices we have now days. Well my 4th child is now 18 months and I had hopes of no more changing sheets in the middle of night. I finally got that with these diapers now I have learned all 3 above brands are garbage. Now they feel like paper to me and a waste of money. When I have ran out of diapers my husband has picked these diapers up at the local store. What happens wet clothes wet beds rashes. I never use these donate them everytime. When I see people say these are cheap diapers and they leak I have no clue what your talking about and my guess is they are buying the wrong size or not putting them on right. Alot of parents don't even realize they are using the wrong sizes for there child and if u are not buying the right size or put them on correct yes u will have leaks. The only time my sons skin is wet is when the diapers have been left on way to long and his peed alot. So if he slept 10 hours over night with no diaper change and he drank alot before bed this happens rarely but when he does this happens. Now while he was tiny no I didn't have this issue. I will say these are amazing diapers and I have tryed many diapers during this time more expensive and less these are the only diapers I will buy. It's also the first time ever with all my kids I didn't wake up many times with newborn having wet clothes and soaking the bed all thoughout the night some night soaking me too. There overnight diapers are really amazing too. I would recommend these to anyone and I would never do so for luv pamper huggies I see those as a waste of money cheap diapers. These are perfect, know the correct size buy bigger keep diapers above belly button to many buy them to small.

Frequent leaks
Size: Size 2 (184 Count)
These diapers leak through frequently. They also run small so make sure to size up. My LO wears a size 1 in other diaper brands but mamabear’s size 1 was tiny. Had to exchange for a size 2.

AMAZING quality & price
Size: Size 7 (80 Count)
Great diapers at an unbeatable price—by far the cheapest option I’ve found. They’re also the only brand that fits my toddlers well since they aren’t potty trained, which has been a huge plus. The quality is solid for the price, and they hold up well overall. The only small downside is that the fit around the legs can occasionally shift a bit. Doesn’t irritate the skin often. Great moisture absorption. Overall, they’re well worth it and a great budget-friendly option.
