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.

Glad I chose these Sturdy, Fluffy Pillows
Color: White, Size: 18x18 Inch
Took me forever to decide which pillows to buy....Price won out. There might be better out there, but I really can't see how. They plumped up really nicely. I once learned from a manager at a big box dept store when purchasing a goose down pillow how to 'activate' the pillow. Basically, he violently threw the pillow down onto the floor, then proceeded to beat the tar out of it....That's how it's done. I think many ppl don't do a good enough job when they get their pillows. I watched several videos from ppl who have purchased this type of pillow. And quite frankly, they do not know what they are doing....My pillows are very plump and awesome. I purchased the 20" squares and then chose 18" pillow covers to stuff them into. Perfection. Fat, soft, soothing pillows. Me and my Doggo are quite happy to lounge around on these durable puffs of fluffiness.

Excellent Inserts. Great price point.
Color: White, Size: 12x20 Inch
I purchased the 20x20 first and loved them so much, I purchased these the next day. They come vacuum sealed so please do be careful opening them. It takes a little time and patience. These fluff up so nicely. I manipulated by hand a bit then into the dryer with wool dryer balls on medium heat for about 20 minutes. They are odor free which is a big plus for me and the quality is there for the price. I can't use feather inserts for anything so these are the next best I've found at this price point. I will be purchasing more and I do recommend.

Fluffy and Supportive Pillow Inserts
Color: White, Size: 12x20 Inch, Color: White, Size: 12x20 Inch
I used these pillow inserts for my couch cushions, and they’ve worked out really well. They give my throw pillows a nice full look without being too stiff or flat, which makes the couch feel more put together and comfortable. Filling quantity: They’re nicely filled and give good shape without feeling overstuffed. Durability: They seem well-made and hold their shape well even after daily use. Color: Clean, bright white that works well with different pillow covers. Appearance: They make my decorative pillows look fluffy and full, giving the couch a more finished look overall.

Exactly what I was looking for
Color: White, Size: 26x26 Inch
I bought these to fill some euro pillow covers and they worked out really well. They come vacuum packed, so at first they look flat, but once you open them and give them a little time, they fluff up nicely. They are soft but still have enough structure to hold their shape on a bed or couch, which is exactly what I was looking for. Not overly firm, but not limp either. They give that full, styled look without feeling stiff. The size is true to 26x26 and fills the covers well without looking saggy. I like that they don’t feel hollow like some cheaper inserts can. Quality feels good for the price. They are not luxury pillows, but definitely a solid option for decorative use and they hold up well. Overall, really happy with them and would buy again for other rooms.
