Our Thoughts

When it comes to choosing car seats, safety and convenience should be at the forefront. Both the Cybex Sirona S and the Graco Extend2Fit meet these criteria, offering parents reliable and highly rated options. Each has its unique advantages and minor drawbacks to consider, making the decision largely one of individual preferences and needs.

Firstly, let's overview the Cybex Sirona S. Renowned for its innovative design, this convertible car seat notably features a 360° swivel function which parents have touted as a game-changer for getting their child in and out of the car. This feature can be a boon for those who frequently park in tight spaces or have back issues. The Cybex Sirona S is equipped with advanced safety technologies, including SensorSafe technology and a steel-reinforced load-bearing leg, ensuring maximum safety for your child. It has generous rear-facing and forward-facing weight limits (50 lbs and 65 lbs respectively), which means long-term use from infancy through the toddler years. This is a significant advantage if you're keen on keeping your little one in a rear-facing position longer for safety. Nevertheless, some parents found the installation somewhat complex and time-consuming, which might be a point to consider. Furthermore, it is not certified for air travel in either of its configurations.

On the other hand, the Graco Extend2Fit also goes beyond the standard safety measures with its reinforced steel frame and enables extended rear-facing up to 50 lbs. One of its standout features is the Extend2Fit 4-position adjustable extension panel, providing up to 5" of extra legroom to keep kids in the safer rear-facing position for longer. This model is also versatile, transitioning to a forward-facing harness for kids up to 65lbs and eventually to a highback booster seat for kids up to 100 lbs. It also boasts an FAA-approved configuration in both its rear-facing and forward-facing modes. However, some parents have been challenged by tightening the harness and found the seat cover difficult to remove for cleaning. It also tends to be bulky, possibly making it a less optimal choice for compact cars.

Both the Cybex Sirona S and Graco Extend2Fit are sturdy and well designed, promising safety and comfort for your child. However, there are a few key differences. The Cybex Sirona S stands out for its cutting-edge features and SensorSafe technology, while the Graco Extend2Fit offers extended rear-facing and transitions all the way to a highback booster.

In terms of which to purchase, if you want a tech-advanced, high-quality car seat and don't mind spending a bit more, the Sirona S would be a great choice. However, if you're looking for a budget-friendly, versatile car seat that will grow with your child and offer the option for extended rear-facing, the Graco Extend2Fit would be an excellent choice.
