Our Thoughts

The CYBEX Sirona S and the Graco 4Ever DLX 4-in-1 are two convertible car seats both designed to grow with your child. The Sirona S features a unique 360° swivel design, SensorSafe technology, and enhanced side-impact protection, making it a standout choice for safety and comfort. On the other hand, the 4Ever DLX 4-in-1 boasts a four-in-one design making it suitable for children weighing between 4-120 lbs, meaning it could potentially be the only car seat needed from infancy through to elementary school years.

Both car seats offer an innovative selection of features. The Sirona S is especially known for its 360° swivel function, which allows easy placement and removal of the child. It also offers enhanced side-impact protection and an adjustable headrest for ultimate safety and comfort. Despite its innovative features, some parents found the car seat installation tricky, possibly due to its more specialized design. The 4Ever DLX 4-in-1, conversely, has been praised for its ease of installation, thanks to Graco's Click Connect feature.

In terms of size and weight, the CYBEX Sirona S is slightly larger and heavier, which may be worth considering if space is an issue in your car. Both these models provide robust safety features – the CYBEX Sirona S utilizes SensorSafe technology and a steel frame, while the Graco 4Ever DLX 4-in-1 boasts steel reinforcement and high safety ratings. Importantly, both car seats meet federal safety standards.

In terms of longevity and utility, the Graco 4Ever DLX 4-in-1 outshines with its versatility to adapt through four stages of a child’s growth. However, the CYBEX Sirona S has a higher weight limit for rear-facing use (up to 50 lbs compared to Graco's 40 lbs), allowing the child to remain in the safer rear-facing position for a longer period.

If budget is a consideration, the Graco 4Ever DLX 4-in-1 might appeal more due to its more affordable price range. However, the CYBEX Sirona S offers innovative features and advanced safety technology which could justify the higher price point for those who can afford it.

In the end, the selection depends on your personal needs and preferences. For those who highly prioritize easy installation and long-term use, the Graco 4Ever DLX 4-in-1 is an excellent choice. However, if innovative features and advanced safety technology are your top criteria, the CYBEX Sirona S provides a high-quality and distinctive solution. Whatever your choice, both these car seats offer trusted brand reputations and are designed to keep your little ones safe while on the road.
