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.

Surprisingly amazing chair!
Color: Pink, Color: Pink
tl;dr: If you need a chair that has the features of this one, then this one is a winner! Hits above its weight class for sure. My wife is 5’. She’s small. For whatever reason she ended up with a chair made for big people, like 6+ feet and up to 500lbs type of a chair. She’d often even sleep on it and chill on it. The chair was big enough to fit 2 of her to be honest. It was an expensive chair that I won at some raffle and didn’t like myself. Over the years it ripped (got a cover for it) and even started to get lopsided (from the sleeping) and finally a spring broke (hence the pillow on it in the pictures) She obviously lives pink. I also wanted to get a chair where she could work and not end ip asleep on. Not like we have a couch or a bed for that 😂. This chair is very obviously smaller than her previous chair, it’s also significantly cheaper in price and build, it’s also not as durable feeling or stable, and it’s just not as padded. Yet somehow it’s an amazing chair that we both like better than her previous chair??? Like it’s crazy that this chair somehow works better in so many ways. Her desk is modified to be shorter than normal desks (again, she small lol) and her previous chair was just too big. The wheels are also like SUPER smooth, like you can run a chair race easily with it. It rolls over her rug and tucks into her desk (which is in our bedroom) easily. The amount of space this has save us when the chair isn’t being used is a lot. Previous chair was much bigger and didn’t tuck in at all. The color is nice and the padding is plenty for a small and much lighter than 500lbs woman. I’m 6 feet and 200 lbs and the chair is nice for me as well. My chair is bigger and more secure in the backing, which is similar to this one. The lowest tension setting on my chair is still too high for her to lean back on my chair. This chair has a lower tension minimum and she can easily lean back freely, as well as keep enough tension to work without sagging. This chair is surprisingly outstanding! I’m sure my wife will destroy it quicker than the last one, but it’s so cheap that even if it only lasts 1-3 years, I’ll happily buy it ones or twice more 🤷🏽‍♀️. Maybe by then they’ll invent a comfortable titanium chair that’s affordable that she won’t destroy 😂.

Mid.
Color: Light Purple
The chair is fine, and reasonably easy to put together. However, I've been using it for a little over a year and a half, and it's already falling apart. Random parts of it have fallen off, which is fine because it was still functional. But now the most frustrating part is that the wheels continue to pop off, and while the first attempts to pop them back on worked, they will not stay on now. This is obviously greatly impacting the stability, and I will need to purchase a replacement soon. For this price and lack of long-term durability, I would not buy again.

Alexa messed me up, but the company of the chair made it right!
Color: Light Purple, Color: Light Purple
I wanted something small with arms that moved out of the way when I wanted to slide my chair all the way into my desk for more space. This fit the bill. I loved the color blue and I had that in my cart for a bit. One day Alexa mentioned that an item that was in my cart was on sale. It was the chair. I let it be ordered. When it came it didn't exactly look blue to me. But I kept putting it together thinking maybe it was the lighting in the room I was assembling it in. I brought it to my craft room and lo and behold it is light purple. I looked at my order and sure enough it said light purple. Boo! I looked in my saved cart and the chair was gone. So I accepted it for an error. The next day I checked to see if I could return it. Thought I could, till I read that I would have to pay to return it. So I wrote the seller to tell them to ignore the return. And that was that. Till a couple days later I get an email from the seller asking if I would like a full refund or a replacement at no cost. I was like heck yeah send me the blue one. I was thrilled and I wanted to thank the seller for doing this without the return of the other chair. But I could not find a place to do that now. So here is where I will thank you. Thank you so much for doing this for me. You guys are AWESOME!. I love the chair and I love the blue color. I find it very comfortable, lite, easy to adjust, the size works great for me, and for the price the quality fits my needs. I do hope it lasts me for quite some time. Thanks again!

Awesome chair definitely recommend
Color: Blue, Color: Blue
It was amazing the color was spot on and it was very very easy to put together and the size is amazing for my 11 year old daughter maybe not for an older person it doesn’t recline as much as it says so if you want a reclining chair maybe I don’t recommend this chair but the quality is amazing and the adjustment capability is incredible the noise level is at 0 it is an amazing chair we just got it so I don’t know so much about the dupability so if you want this chair for a child or a tween maybe even a teen easy to put together beautiful blue color this is the chair for you.

Very Straightforward and Easy to Use
Reload type: One Time Reload
I have used this several times, and it has always been a smooth and convenient experience. The biggest advantage is how intuitive the process is. Reloading the balance is simple, quick, and easy to understand without unnecessary steps or confusion. It is especially useful for managing spending, setting a shopping budget, or keeping funds ready for future purchases. Instead of entering payment details every time, having balance available makes checkout faster and more convenient. I also appreciate how quickly the funds are applied, allowing immediate use once the reload is completed. This is one of those simple Amazon features that works exactly the way it should. Overall, easy, efficient, and user-friendly. I have been very satisfied with it. Five stars.
