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.

CYBEX were awarded Which? Baby and Child Brand of the Year in 2024!

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.

Cat Approved
So I have several self warming pads, this is the first one all three cats like. The outer cover is similar to the fake rabbit fur blankets and that was a huge hit in my house, everyone kneaded it excessively. While the pad isn't thick it does generate some heat keeping my smallest cat warm. And even my fattest guy liked it. It is made well and I am already ordering a second.

LOVE this warming cat bed!! With a tiled or cement floor, this is an ideal strategy to remind little pets that this is a warm spot for you to lay your head <3

My cats love these. Will choose these over and over again. I had to buy multiple so they could each have one. Does seem to help keep warmth in. It’s also easy to clean.

Warm, Comfy, and No Electricity Needed
Size: 20.0"L x 16.0"W x 0.5"Th, Color: Grey
This self-warming cat mat works well — it reflects body heat and stays noticeably warm without plugs or electricity. The surface is soft and cozy, and most cats seem to take to it quickly. It's lightweight, easy to clean, and fits well in beds, carriers, or on furniture. It’s a bit thin, so adding extra padding underneath may help. Also, it can slide on hard floors, so best used on carpet or fabric surfaces.

He loves it. I wish I had purchased the large instead of the medium, but it still fits him okay. If he stretches out, it won't, though. :) He's a big boy. I have it lying on a bed in the spare room, where he often is, looking out the window. It's soft and makes barely any noise. It doesn't slip on the bed. I might on the floor. With anything new that we buy him, we spray it lightly with catnip spray and he always takes right to it, as he did with this. It's warm under his body. He's happy, we're happy! :) I ordered the larger one. It got here today! I moved the smaller one to a window seat. I hate when the delivery guys add, was handed directly to homeowner, no it wasn't It was put in a package box outside, ringing the door bell is not the same as handing it directly to me! LOL
