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.

An excellent strapless option
Size: XX-Large, Color: Nude
Extremely comfortable! It didn’t slip down like some do, so I don’t feel the need to tug it up. Felt like I wasn’t wearing anything at all. I also like that it comes with optional straps. Great coverage. The two things to watch for is the top seam is a little thick, so it won’t work under thin tops, and the pads will move around, but they are easy to adjust or remove. On the whole I find this a great fit and easy to wear, at an excellent price point.

Great!
Size: XX-Large, Color: Nude
REVIEW FROM A REAL PERSON WITH NO FINANCIAL INCENTIVES This is my first time ever wearing a strapless bra and I really like this one! It's very comfy and feels like wearing any other sports bra just, well, without the straps (though they do include straps in the box that you could attach if you wanted). I'm somewhere around a 40DDD and got a 2x and it fits well, though I did wear it to work one day and by the end of the day, it did feel like it was digging/squeezing into my side a bit too much (however it had been 10hrs by then). The bra IS stretchy but if I were really any bigger, I think I'd want to go to a 3x. Only very minor issues with it slipping, nothing even close to where I was worried anything was going to pop out or anything, even after being out in 90F heat.

Stays in place
Size: Medium, Color: White
I’d give the Letts Jolli Push-Up Strapless Bra a solid 3 stars. The fabric quality is actually really nice—it feels soft, smooth, and comfortable against the skin, which is a big plus for something strapless. It also does a great job staying in place. I didn’t have to constantly adjust or worry about it slipping down throughout the day, which is usually my biggest concern with strapless bras. That said, the “push-up” aspect was a bit disappointing. It didn’t really provide much lift or enhancement like I expected, so if you’re looking for noticeable cleavage, this might fall short. Overall, it’s comfortable and reliable for staying put, but it doesn’t quite deliver on the push-up promise.

It holds the girls up!
Size: Large, Color: Nude
This is absolutely the best strapless bra I have ever owned! It stays put, doesn’t ride up or ride down & I don’t have to adjust it. It fits true to size. Worth the money! It’s also not the sexiest bra, but when you just want a strapless bra that holds the girls up, I promise it will do that!

Will be my go to strapless for sleeveless everything
Size: Medium, Color: Nude
Ok so, this did not disappoint. Supportive and has cups/padding so there's no show through. Stays in place. Sturdy will not roll on you or stretch out half way through your day/ evening. Straps are included but not necessary. Do not try to put on right out of the shower. You also need to step into it to pull up. Do not try to pull it over your head. Perfect for under spaghetti string tops/tube tops. I am 135 lbs, 34DD or a 36D depends on bra. I bought a medium and it holds everything tight. I believe I could also go with a large at this weight to have a little less compression.
