Our Thoughts

The Clek Foonf and the CYBEX Sirona S are two high-quality car seats known for their superior safety features and usability. Each offers unique features and benefits that make them stand out in the realm of convertible car seats.

The Clek Foonf boasts a reputation for its safety, style, and advanced features. As a convertible seat, it's designed to accommodate children from infancy to toddlerhood, adapting to your child's growth. Leading in safety technology, the Foonf features a steel anti-rebound bar and energy-absorbing foam layers. It's also appreciated for its narrow design, allowing for fitting multiple seats in a vehicle - a great plus for families with several children. However, it's worth noting that it has a higher weight, which can make moving it between vehicles a challenge. The Foonf also offers a rear-facing weight limit of 43 pounds and a forward-facing limit of 65 pounds.

On the other hand, the CYBEX Sirona S car seat is known for its unique 360-degree swivel feature, which makes placing and removing your child from the seat significantly easier. The Sirona S features SensorSafe technology and a load-bearing leg for added stability, enhancing child safety. It also boasts an adjustable headrest, providing comfort for growing children. With a convenient cleaning process thanks to its removable and machine-washable cover, it differentiates itself from the Foonf, which can be cumbersome to clean. For the Sirona S, it's important to note it has a slightly higher rear-facing weight limit than the Foonf at 50 pounds, but matches the same forward-facing limit of 65 pounds.

While both car seats are stellar in terms of safety and quality, they also share a challenge in terms of installation. Some parents have found that both the Clek Foonf and the CYBEX Sirona S are complex and time-consuming to install. However, once in place, they offer superior stability and child safety.

When considering which car seat to choose, it comes down to your specific needs and preferences. If the convenience of a swivel seat and easy cleaning process stands out to you, then the CYBEX Sirona S might be your best option. Alternatively, if fitting multiple car seats in one vehicle is your concern or if you prefer a sleek and modern car seat design, the Clek Foonf could be your preference. Both car seats fall into the higher price range, but their advanced safety features and versatility from infancy to toddlerhood justify the investment.
