Cybex Sirona G i-Size Plus Group 0+/1 Toddler Car Seat

The BubsNest Verdict

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.

BubsNest expert analysis of 5 parenting forum discussions

“Award-winning car seat praised for safety and comfort, but with rear-facing limitations”

7.5

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.

What parents love

Safety and ComfortParents praise the Sirona's top safety ratings and say it provides excellent comfort for children from birth to around 4 years old.
Versatile UseThe ability to use the seat rear-facing and forward-facing is appreciated, allowing it to grow with the child.
Stylish DesignThe Sirona's modern, sleek design is frequently called out as an appealing feature.

Worth knowing

Rear-Facing LimitationsSome parents report the Sirona doesn't provide enough leg room to be used rear-facing up to the full 4-year age limit.
Installation DifficultyA number of users, especially smaller or less mobile parents, find the Sirona challenging to install properly, especially when using ISOFIX.
Weight and BulkThe Sirona's substantial weight and size make it difficult for some to move the seat in and out of the car.

Best for

  • Families seeking a long-lasting, high-safety car seat
  • Taller children who can use the Sirona's full rear-facing capacity

May not suit

  • Parents with limited mobility or strength who struggle with the Sirona's weight and installation
  • Smaller vehicles with tight spaces that limit the Sirona's rear-facing leg room

Tips from parents

Before You Buy

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

Getting the Most Out of It

Watch the installation video carefully and practice the process before your child's first ride.

Safety Note

Be sure to follow all safety guidelines, including keeping the seat rear-facing as long as possible.
