Our Thoughts

When you're shopping for a new car seat, it's often helpful to focus on safety features, comfort, size, and longevity. Comparing two popular models — the Cybex Sirona S and Graco 4Ever DLX — can help inform your decision.

The Cybex Sirona S stands out for its innovative features and a focus on enhanced safety. From the SensorSafe technology that alerts you to potentially unsafe situations to the impressive side-impact protection provided by the reinforced steel frame, it's a car seat designed to put parents' minds at ease. Yet the standout feature is undeniably the unique 360° swivel design, easing not only the process of getting your child in and out of the car but also changing between rear and forward-facing configurations at ease. The seat also boasts maximum weight limits of 50 pounds for rear-facing, and 65 pounds for forward-facing. One of the few downsides is its installation which some parents found complex and time-consuming, but the advanced safety features and longevity from infancy to toddlerhood certainly compensate for it.

On the other hand, the Graco 4Ever DLX is an impressively versatile seat that grows with your child from infancy through their grade school years. It offers five stages of use: an infant car seat, convertible car seat, high back booster, backless booster, and even a seat belt trainer. Unlike many car seats on the market, the 4Ever DLX provides tremendous value for the price, eliminating the need for multiple purchases as your child grows. It has a maximum weight limit of 40 pounds for rear-facing, 65 pounds for forward-facing, and extends up to 120 pounds in its booster mode. With its SnugLock installation system and single-motion adjustment for harness and headrest, this car seat is user-friendly on top of being long-lasting.

In terms of safety, the models are relatively on par, providing excellent protection and meeting federal safety standards. Both have been equipped with a reinforced steel frame for stability, a 5-point harness for secure fitting, and have the same expiration period of 10 years. However, one notable difference is their FAA approval; the Graco 4Ever DLX is approved for both rear-facing and forward-facing modes while the Cybex Sirona S is not FAA approved for any of its configurations, which will be a deciding factor if you travel frequently by plane.

So, which to choose? If outstanding safety features and innovative design are your top priorities, the Cybex Sirona S offers excellent value for its higher price point. But if you're seeking a one-time purchase that will comfortably see your child through to their pre-teen years, the Graco 4Ever DLX delivers excellent value and an impressive lifespan. Moreover, keep your travel needs in mind; if you're a frequent flyer, Graco 4Ever DLX will be a more suitable choice. Both seats excel in comfort, safety, and adaptability, making them top choices for a long-term car seat investment.
