Product 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.
  • 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.
  • 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.

Handy Tool for Frequent Flat Tire Repairs
Size: 3 mm 4.5 mm 6 mm Tire, Number of Items: 3
Good quality and easy to use. As someone involved in emergency services, we deal with flat tires often, and this tool has been really helpful. The bits are sharp, durable, and make the repair process quicker and cleaner. Great to keep on hand for regular use or in a roadside kit.

Makes For Quiet Rides
Model: 10 SqFt(0.95 SqM)
Comparable quality and performance to name brand competitor. It sticks on strong, easy to apply, and does make a difference in sound reduction. Turn your hollow shell sounding vehicle panels into solid sounding walls.

Must for subwoofers. True 2mm spec. High quality.
Model: 36 SqFt(3.4 SqM), Model: 36 SqFt(3.4 SqM)
Let me start of by saying WOW! This made a huge difference in the SQ of my L7S pushing 930w rms. Before I had major rattles in my 2020 Honda Civic SI. Taking the time to do this to my trunk and Lid made me realize just how loud my subwoofer actually is. It literally eliminated the rattles throughout my whole car. I still plan on doing this to my doors and rear deck but once I upgrade the speakers. I still have half of the box just doing the trunk and lid so 1 box of 36sf will be enough for most of the areas that need to get done. You may need a little more overall. This is true 2mm spec. Very sticky and easy to apply. It just take time to finish the work correctly and roll it down. It is not as heavy as I thought it was going to be. The size of the sheets are perfect for what you need to do. The value is on point for the quality. It does not rip very easily but you can cut it to size without any problems. Again, This is a must buy for anyone who is pushing 1000w rms or more.

Quality product you
Model: 18 SqFt(1.7 SqM), Model: 18 SqFt(1.7 SqM)
Summary: Great quality product, priced right. Cuts and installs easy-follow the instructions people!! PRO TIP-you don’t need to cover every square inch. OVERKILL!! Think about it-when a bell rings you could put your fingers on the edge and silence it right? Same rules apply here. A strip or square will isolate the vibration and notice when placed correctly— knock on the surface and see what vibrates or what part makes the loudest drowning and that’s a good clue of where you should put a piece of this…unless you’re trying to use it for temperature insulation no need to go ape on it. If you look at the bottom of a stainless steel sink, it’s got a stripe or a small sticker of insulation that keeps it from rattling. You can do that here. What’s important to note is the instruction specifically say use a roller to roll the ribs out until it’s smooth that way you’ve got maximum adhesion. I see a lot of pictures and videos from people that finished their install and didn’t follow this simple instruction. It makes sure that it’s stuck down before you put all your paneling and carpet back in and it’s a small step with a cheap wooden roller it’s easy. I’ll say the installation with this product is a breeze. You can use sharp scissors or a blade. It does get gummy after a while, and you may need to clean off your blade or your scissors, but it cuts very well and the ribs make it easy to size in space the thickness is fantastic and the backing paper comes off quite easily. I’ve done lots of installations with Graphics emblems you name it and this product is very easy to use and represents good value.
