Cybex Sirona Ti i-Size Plus Car Seat
The 360-degree rotation makes getting kids in and out much easier on your back, and the safety credentials are solid. Perfect for parents who struggle with back pain or have narrow car doorways, but skip it if you have a smaller car or need something that works seamlessly from birth.
⚠️Check your specific car model's compatibility before buying—the base doesn't fit securely in all vehicles, and the rotation mechanism can feel stiff in certain car configurations.

“Award-winning car seat praised for safety and comfort, but with rear-facing limitations”
Solid Choice
The Cybex Sirona is a well-regarded car seat that has won multiple safety and design awards. Parents highlight its comfortable, stylish design and ability to accommodate children from birth to around age 4. However, some note the limited leg room when rear-facing and find installation more difficult than expected, especially for smaller or less mobile users. Overall, it's a solid choice for families seeking a safe, long-lasting car seat, though it may not suit all needs or preferences.

Tips from parents
Check your car's compatibility and measure the rear-facing space to ensure the Sirona will fit your needs.
