Our Thoughts

The CYBEX Sirona S and the Nuna Rava are both high-end convertible car seats equipped with state-of-the-art safety features. However, there are key differences in the design and functionality that might sway a parent's decision based on personal preferences and lifestyle.

The Sirona S by CYBEX is lauded for its unique 360° swivel feature, which brings convenience for parents when placing a child in the car. This function could be a lifesaver for those with back issues or who routinely park in tight spaces. Also, it boasts a SensorSafe Technology, a fascinating feature that offers critical safety alerts by connecting to a smartphone app. It offers advanced side-impact protection and accommodates kids up to a weight of 65lbs in the forward-facing position, and 50lbs when rear-facing. However, some parents might find its size quite bulky, especially for smaller vehicles, and the installation often challenging. Although the seat cover is machine washable, making cleaning easier, its higher price point might be something for parents to consider.

On the other hand, the Nuna Rava emphasizes unmatched safety and comfort, featuring an all-steel frame and advanced side-impact protection. An enticing feature of the Rava is its legroom extension, which allows up to 2 inches of added legroom in the rear-facing mode. Like the Sirona S, the Rava can accommodate children up to 65lbs in the forward-facing position and 50lbs when rear-facing. Though installation is markedly simpler with the unique door mechanism, the trade-off comes in its size - this model is quite bulky, making it a less optimal choice for smaller cars or those needing to frequently move the seat. Additionally, parents have commented that the fabric tends to stain and show wear relatively easily.

In conclusion, both the CYBEX Sirona S and Nuna Rava stand out for their impressive safety features and long-term value in accommodating growing children. The Sirona S might be a better fit for those who appreciate innovative features and can navigate around the initial complexity of installation. The Nuna Rava, on the other hand, would be an excellent choice for those who prioritize the ease of installation and exceptional comfort for their child. Looking at both products and considering their features, we recommend the Nuna Rava for its superior safety features if your budget allows for it. The simple installation and comfort it offers for your child makes it an excellent investment despite its higher price point.
