Key Features

UP TO 50% HIGHER SAFETY LEVELS

The Sirona T i-Size provides superior protection in both travelling directions in the case of an accident. When in the rear-facing position it reduces the risk of an injury to the child’s neck and head, resulting in 50% higher safety levels*. In the case of an accident, the child is pushed towards the seat shell, where forces get distributed over the entire surface therefore reducing the impact. Legally a child must stay rear-facing until at least 15 months and 76 cm in height but we recommend using it for longer, up to four years if possible. The Sirona T i-Size’s versatility allows for forward-facing positioning once the child has grown, offering freedom of choice that suits you and your child.

ALL-ROUND AIR VENTILATION SYSTEM – COMFORT FABRIC

The Sirona T i-Size breathable materials keep your little one cool.

ALL-ROUND AIR VENTILATION SYSTEM – PLUS FABRIC ONLY

The Sirona T i-Size PLUS provides all-round air ventilation for year-round comfort. Air circulation and comfort are further enhanced due to its specially designed 3D mesh structure that increases breathability up to six times**. The sun canopy with mesh inserts to keep your child cool and protected.                                                                     

360° ROTATION - EFFORTLESS ON & OFF BOARDING

With the Sirona T i-Size, you can effortlessly on and off-board your child, thanks to its 360° rotation that smoothly rotates towards the car door. This feature minimizes any potential strain on your back during the boarding process. Legally a child must stay rear-facing until at least 15 months and 76 cm but we recommend using it for longer, up to four years if possible. Once your child has grown, you can easily choose between the rear or forward-facing position. It’s so simple, using just one hand, the seat can be smoothly rotated and reclined, ensuring that even the youngest passenger is comfortably boarded.

NEW INTEGRATED UPF50+ FABRIC SUN CANOPY – PLUS FABRIC ONLY

The brand new integrated sun canopy on the Sirona T i-Size is made of UPF50+ fabric**** and offers your child excellent sun protection in the car. As your child grows the sun canopy moves seamlessly with the headrest, and on dull days can be simply folded back and tucked away. For warmer days, the sun canopy is equipped with mesh inserts, which guarantee ideal breathability and ventilation.

FROM BIRTH TO APPROX. 4 YEARS

Thanks to its height-adjustable headrest, the safety of the Sirona T i-Size evolves with your child, accommodating their rapid growth. With its 12 different positions, the car seat adapts to your child’s size during the first four years, providing steady protection throughout this time. When adjusting the headrest height the harness adjusts automatically to ensure a comfortable fit.

25% MORE SIDE IMPACT PROTECTION

The Sirona T i-Size is equipped with the proven Linear Side-impact Protection System (L.S.P.) which enhances safety in the event of an accident. Activate the L.S.P on the side of the car seat nearest the door, together with the energy-absorbing shell of the seat, the extended side protection reduces the initial impact forces by up to 25%**. If needed, the L.S.P. System can be easily stored away in the case of limited space in the car.

INTUTITIVE ISOFIX BASE T

The ISOFIX Base T serves as a secure base for the Sirona T i-Size seat unit. It is equipped with ISOFIX and a load leg for easy and secure installation. The ISOFIX release buttons are user-friendly and intuitive, visual indicators confirm the correct setup on both the ISOFIX buttons and Load Leg. With these features, setting up the Sirona T i-Size is as easy as it gets, reassuring parents and providing a safe and comfortable ride.

COMFORTABLE SLEEPING POSITION

The five recline positions of Sirona T i-Size can be easily adjusted with just one hand, freeing up your other hand for different tasks. This feature works in both rear and forward-facing positions, providing additional comfort for your sleeping child while travelling.

HARNESS MAGNETICS

Small magnets located on either side of the Sirona T i-Size, allow you to attach the metal parts of the harness, keeping the straps  out of the way for a simpler the onboarding.

NEWBORN INLAY – SUPPORT FOR SMALLER BABIES

The Sirona T i-Size includes a removable newborn inlay which provides a near-flat lying position, allowing for the use of the car seat from birth in the rear-facing position. The inlay helps keep the baby’s head in the most ergonomic position, especially while sleeping, to avoid breathing complications. To accommodate your baby as it grows, the newborn inlay should be removed once your child is taller than 60cm.

COMPATIBILITY

The Sirona T i-Size is compatible with the CYBEX Base T and Base Z2.

Comfortable and cool. Does not ride up.
Color: 01-multicolour (4-pack), Size: Medium
Extremely comfortable. Stays cool. Ample coverage. Quality material. They do not creep up. I ordered a medium which I generally take a size small. I have reordered and will reorder again to add more colors to my collection.

Great Value for Cool Thigh Protection
Color: 02-multicolour (4-pack), Size: XX-Large
For the price, I'm not sure there are better women's boxer shortlettes anywhere. I've tried more expensive brands, and for quality and cooling, these are right up there. I have other bamboo viscose undies that still get gross when I get sweaty in the summer, but these, with the large mesh panel, really help wick away a lot of that moisture, keeping you feeling dryer and cooler. I find that the leg openings are comfortable and don't roll up! and the waist band doesn't dig, nor does it roll down. These do not provide any compression, and I wasn't looking for any. I just wanted some cooling, thigh protecting women's boxers that wouldn't break the bank. These are them! Bonus- I've washed them and put them in the dryer (following their instructions), and they haven't shrunk; they look about the same and are nice and soft.

Great for the entire family but expensive
So far so good. The brand of boxers we had been buying changed their style and construction so we needed to find an alternative. These have held up well so far to multiple weeks of frequent washing and wearing from the entire family. We did size up from the usual 6/M we normally buy and ordered large to prevent the legs from rolling up which worked out great. Our daughter likes the length and how soft the fabric is for wearing under skirts and gym shorts and liners stay put without moving or leaking as another reviewer mentioned. Our son says they are comfortable and fit well being just supportive enough without being constrictive. We all agree that there seems to be not enough fabric in the back as they tend to be much tighter across the backside than the front and that also causes the waist band to ride lower in the back than the front. These have better seam placement than some brands we tried with no seam across the lady bits and no seam down the middle of the back side so they are more much comfortable but the cost is also much higher and that is why we're only giving it 4 stars. These will stay in the rotation until we find something cheaper that both us and the kids like.

Pregnant lady review! Soft, comfortable, cool.
Color: 03-multicolour (4-pack), Size: Large
So soft, comfortable and cool. I'm pregnant and I've gained weight in my legs. I love wearing dresses but my thighs were rubbing together too much. These are perfect to wear under dresses. I also wear them under my bibs at work and it keeps me from getting overheated but I don't have to worry about whether or not my underwear show since they just look like shorts. I wish these came in maternity. I just keep them below my belly. I'll be buying more for sure.

I want to live in these
Color: 01-multicolour (4-pack), Size: Medium
I bought 4 different sets of new underwear. Unfortunately these came last. It’s unfortunate, because if they had come first I would have cancelled all my other orders or returned them and ordered more of these. I never want to wear anything else ever again; these are the comfiest undies I’ve ever owned, I want to live in them. I can wear them under pretty much anything except leggings or very tight pants (but let’s be honest, I don’t wear those anyway.) They are incredibly soft and breathable, they wash well, don’t roll, keep my thighs from rubbing, are comfy to sleep in, and the colors were true to the photo. Just a heads up, they are on the thin side and just a bit see through in the rear. I’m 5’5” 140lbs and the mediums fit perfectly, they go about mid-thigh.
