Sirona T i-Size 0+/1

Enjoy the ultimate travel experience with the CYBEX Sirona T i-Size rear-facing car seat. Your child can enjoy the height of comfort with features like all-around air ventilation promising pleasant temperatures in all seasons. Smooth 360° Rotation lets you get them on and off-board effortlessly and helps you switch between rear or forward-facing travel. Recline the seat with one hand, for extra comfort on the road. And you can enjoy peace of mind through safety features such as integrated Linear Side-impact Protection. Get ready for blissful trips with your child, with the Sirona T i-Size.

PLUS: All-round air ventilation provides year-round comfort. And the Plus fabric version has even better airflow, with a 3D mesh that increases breathability up to six times (compared to conventional fabric). The Plus line also features a sun canopy with mesh inserts to keep your child cool and protected.

Up to 50% higher safety

The Sirona T i-Size is a rear-facing car seat providing superior accident protection, reducing the risk of head or neck injury and improving safety by 50% (compared with the same seat forward-facing; results of testing using 2022 ADAC criteria). In a crash, the child is pushed towards the seat shell, where forces are distributed, and lose impact. Rear-facing is mandatory for at least 15 months (76 cm tall). After that, you are able to rotate the Sirona T-Size forward-facing, although, we recommend rear-facing travel for up to four years if possible.

Easy Boarding Position

Get your child in and out of the car with ease. 360° rotation lets you swivel the Sirona T i-Size smoothly towards the car door with one hand, for easy boarding and less back strain. Rear-facing is mandatory for at least the first 15 months (up to a height of 76 cm). Then you can keep your child rear-facing or turn them forward for extra comfort.

Safe Travels up to 4 Years

In its rear-facing position, Sirona T i-Size reduces the risk of injury in a head-on collision. Tests show that the force of impact from a frontal crash is distributed more evenly over a large area of the car seat shell. We recommend using the Sirona in the rear-facing position until the child is at least 15 months old and longer if possible.

Maximum Comfort in the Car

The one-hand recline function makes it easy for parents to adjust the seat while keeping their other hand free. The Sirona T i-Size car seat has 5 recline positions in both rear and forward-facing modes, increasing comfort for sleeping and traveling.

⭐️⭐️⭐️⭐️⭐️ Perfect for My Suit-Loving 9-Year-Old 🤍👔✨
My 9-year-old is obsessed with suits, and this one was a total win! 😍 The 3-piece set (blazer, vest, and pants) makes him feel so grown-up and confident. The linen material is lightweight and breathable, which is perfect for warm weather ☀️ — and it doesn’t wrinkle easily, which I appreciate as a parent 🙌. He loves that he can wear it different ways — full suit, just vest and pants, or blazer and pants. 👌 The fit looks sharp, and the adjustable waist is super helpful. Perfect for weddings, school events, church, or any time he wants to dress to impress. 💙 Definitely a favorite in our house! 🎉

Adorable special occasion suit for boys
Size: 5, Color: Light Blue, Size: 5, Color: Light Blue
I ordered this 3-piece suit for my son and even though it’s currently a little too big for him, I couldn’t resist keeping it because it’s absolutely adorable! The quality really impressed me right out of the package. The fabric feels lightweight and breathable, which will be perfect for warmer weather, and it has a nice polished look without feeling stiff. The set comes with a blazer, vest, and pants, and each piece is very well made. I love the little details like the lapel on the jacket, the adjustable strap on the vest, and the adjustable waist on the pants, which will definitely help as he grows. It looks like a much more expensive suit than it actually is. Even though my son will have to grow into it, I’m already excited for him to wear it. I’m thinking it will be perfect for Easter next year or any special occasion. It’s such a cute outfit, and I love that the pieces can be mixed and matched for different looks. Overall, I’m really happy with this purchase and can’t wait to see him wearing it! The blue color goes well for any occasion and I may have to order my husband a suit in matching shade of blue so they can be twins. The size looks accurate for boys 5T. I took a picture to show the pants next to a pair of unwashed Oshkosh B’Gosh brand straight leg 5T boys denim jeans.

Perfect Summer Suit for Boys – Stylish and Comfortable!
Size: 5, Color: Light Green
I’m so impressed with this **boys' linen summer suit**! 👔🌞 It’s the perfect outfit for warmer weather while still looking sharp and stylish. The **linen fabric** is lightweight and breathable, making it ideal for those hot summer days. My son looked fantastic in it, and he was comfortable all day long, which is a big plus! The suit fits **true to size**, and the cut is modern yet classic. The **jacket** has a great, tailored look without being too stiff, and the **trousers** are just the right fit—not too baggy or too tight. It’s a very **polished** look for events like weddings, family gatherings, or holiday parties. I also love that the **color options** are vibrant and fresh, perfect for summer. The suit is **easy to care for**—I was worried about linen wrinkles, but it’s held up well after a few washes, and the fabric still looks crisp. Overall, this **boys' linen summer suit** is an excellent purchase for any special occasion or just to make your little one look extra sharp during the summer months. **Comfortable, stylish, and durable**—highly recommend! 🌟👔
