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.

Transformative for Dry, Cracked Heels!
Color: Original Grey
I recently purchased Dr. Frederick's Original Moisturizing Heel Socks, and they have truly transformed the condition of my feet! I can’t recommend them highly enough. Effective Moisturization: These socks are infused with moisturizing agents that work wonders. After just a few uses, I noticed a significant reduction in dryness and cracking on my heels. My feet feel softer and smoother, and I love that I can wake up to beautifully moisturized skin. Comfortable Fit: The socks are incredibly comfortable to wear, with a snug yet gentle fit. I appreciate that they don’t feel restrictive, allowing me to walk around my home while wearing them without any discomfort. They are also lightweight, making them easy to slip on before bed. User-Friendly: They are super easy to use—just wear them overnight, and let the socks do their magic. I love the simplicity of incorporating them into my nighttime routine. Durable Quality: The quality of the socks is impressive. They wash well and have maintained their shape and effectiveness after multiple uses. I feel confident that they will last a long time. Final Thoughts: If you're struggling with dry, cracked heels, I highly recommend Dr. Frederick's Original Moisturizing Heel Socks. They are a fantastic investment in foot care and have made a noticeable difference in the health of my skin. These socks have become a must-have in my self-care routine!

These worked for me!
Color: Original Grey
They worked great. I bought these for cracked sore heels. It took 2-3 weeks but my heels no longer hurt and the cracks have closed and look more like an indention than a crack now. They feel so much better, but I'll probably wear them another week just to be sure they stay healed. They look and feel like regular socks from the outside but only cover the heel with the toe open. Not think but not thick, again like regular socks. They would probably be slippery on a smooth surface the same as socks. The inside feels like rubber or something smooth at the heel. I have washed them once each pair and accidentally dried one pair in the dryer. They still seem to feel the same so I think they're fine. They're pretty inexpensive and had different colors and sizes.

Truly Helped My Cracked Heels
Color: Original Grey
I didn't include a photo cause they look exactly like their advertisement photo. I so liked the silicon-type heel lining as it kept the heel-repair cream on my heel and did not get soaked up by the sock. But, it is so, so slippery when walking around in them! Take care to be mindful when you set each foot down as the lotion can slide your heel across the sock quite a bit. If these socks were for an elderly person, I would have them only sit while using the sock - no walking around for fear of falling. I have larger ankles and found that having both the top and the bottom hems/elastic, etc. the same size to be quite troublesome and was not a nice feeling or fit on my upper hem that hit my ankle. Don't get me wrong, I am so glad that I got them and I continue to use them and they are helping my horribly-cracked heels greatly, but I find that I have to keep moving the top hem up and down so that it doesn't stay in one position as it cuts in to my ankle. My feedback and advice might be to please make the upper hem somewhat larger than the one that is on the bottom and goes over my actual foot. They really should not be the same circumference...or else make different sizes - S, M, L, etc. That's really my only complaint or "con" to ordering these. I think they are a great concept and I like the fact that I can throw them in the washer and dryer.

Actually works, and really well
Color: Original Grey
I bought these because I got them on a great deal and was quite skeptical, but they actually worked exactly as advertised and I saw a huge difference after the first night! I understand why they don’t cover the whole foot like a regular sock (it would be stifling), but it would be incredible if they made a pair that go forward enough to cover the ball of the foot. One pair lasted about 3 weeks before the moisturizer wore out (I did notice a dropoff after washing, so for best results put them on when you’re clean and just for overnight, so you can avoid washing). Apologies for no photos- no one wants to see the before photos. These work so well I’ve just come back to order more even though I’m now paying full price. Definitely, definitely recommend.
