When comparing the Cybex Sirona S and the Evenflo Gold Revolve 360 car seats, it's evident that the Cybex Sirona S stands out in rear-facing capacity, accommodating weights ranging from 4 to 50 pounds and heights up to 49 inches. In contrast, the basic variant of Evenflo Gold Revolve has a rear-facing weight limit of 40 pounds and 40 inches, making the Sirona S a preferable choice by default for the rear-facing position.
However, there are other variants for the Evenflo seat. The Evenflo "Revolve Extend" or Gold Revolve Extend" variants are recommended for those prioritizing extended rear-facing. These variants increase the rear-facing weight limit to 50 pounds and include a reversible, ergonomic leg rest that adds comfort for growing legs.
Both car seats offer similar limits for forward-facing capabilities, supporting weights up to 65 pounds and heights up to 49 inches.
The Evenflo Gold Revolve 360 also has a high back booster advantage of a weight limit of up to 120 pounds and a height limit of 57 inches. The Cybex Sirona S, on the other hand, lacks a high-back booster option.
Cybex Sirona S | Evenflo Gold Revolve 360 | |
Width | 19 inches | 19.8 inches |
Height | 24 inches | 25.9 inches |
Depth/Length | 30 inches | 21 inches |
Regarding size, both options are almost similar in width at 19 inches and 19.8 inches, respectively.
For height of the seat, the Cybex Sirona S measures 24 inches, and the Evenflo Gold Revolve 360 comes in slightly taller at 25.9 inches.
Another difference between these two car seats is their depth or length. The Cybex Sirona S measures 30 inches, while the Evenflo Gold Revolve 360 only measures 21 inches.
The Evenflo Gold Revolve 360 might be the better option if your vehicle has limited space due to its smaller length.

When considering the installation of the Cybex Sirona S with LATCH, some parents suggest a specific technique to ensure a secure fit. They recommend threading the belt's tail back through and standing behind it while pushing down firmly. This method helps prevent any wobbling once the belt is tightened.
Some parents think that the seat's instability might be related to the quality of the vehicle's seat. One parent mentioned that they noticed an improvement in stability by installing the Cybex Sirona on the unused rear seat side.
Despite online installation guides, recent parent feedback on installing the Cybex Sirona S with SensorSafe is predominantly negative, highlighting difficulties, time-consuming processes, and concerns about seat stability.
On the other hand, the Evenflo Gold Revolve 360 offers a simplified installation process with its Sure360™ Safety Installation System. This system integrates the LockStrong™ bar for secure base attachment and the Tether360™ for stability within the vehicle.
Parents often recommend starting with the vehicle seat belt to avoid repeated installations, considering the weight limits associated with LATCH installations.
Parents have reported concerns about wobbling in both seats. Still, it's essential to note that limited movement, within 1 inch, on the belt path is acceptable. It's crucial to assess wobbling only on the belt path, avoiding testing from the headrest or other areas to obtain an accurate indication.

The Cybex Sirona S stands out for its advanced safety features, notably the load leg, an integrated structural element extending to the vehicle floor, diverting crash forces away from the child. The height-adjustable load leg ensures a precise fit in your car.
The Cybex car seat also incorporates an anti-rebound design to minimize rearward movement during a crash, reducing force on the child. The Linear Side Impact Protection (L.S.P) feature enhances safety in side impact scenarios by directing impact forces away from the child's neck.
Including the SensorSafe 4-in-1 Safety Kit in Cybex Sirona S adds an extra layer of security, alerting parents to critical situations through smartphone connectivity.
Despite its comprehensive safety features, some users report dissatisfaction with the Cybex’s floor anchor's perceived ineffectiveness.
On the other hand, the Evenflo Gold Revolve 360 underwent rigorous testing, exceeding federal crash test standards. The optional Sensorsafe system offered in the Gold Revolve Extend variant provides real-time alerts for chest clip unbuckling, temperature extremes, unattended children, and extended seating time. However, user reviews suggest that the Sensorsafe feature has room for improvement, with concerns about false alarms and occasional issues with the accompanying app.
One notable limitation of these two car seats is their unsuitability for air travel. The strap designs of both seats also pose challenges, with easily tangled straps, large rugged plastic buckles that may dig into a child's legs, and difficulty adjusting their straps.

The swivel features of these car seats have notable differences. The Cybex seat's swivel function is limited because of the tether required for secure attachment in forward-facing mode. This means the swivel is only operational when the seat is rear-facing.
On the other hand, the Evenflo Gold Revolve 360 stands out with its impressive 360-degree rotation capability. Unlike the Cybex model, the Evenflo 360's swivel remains functional even in forward-facing mode because its tether is attached to the base, not the main seat.
The Cybex Sirona S and Evenflo Gold Revolve 360 car seats are designed with breathable materials, ensuring comfort for your child during car rides. They are relatively similar in portability, weighing 30.4 pounds and 29.6 pounds, respectively. The machine-washable cover adds a practical aspect to maintenance, making it convenient for parents to keep the seats clean.
In terms of spaciousness, both models provide a roomy environment for the child, and they share the convenience of a no-rethread harness, simplifying the adjustment process as your child grows.
The Evenflo Gold Revolve 360 seat cover is notably easier to remove than the Cybex Sirona S. It's worth noting that the Evenflo Revolve 360 offers an improved "Quick Clean Cover" variant, which may be a more appealing option for parents seeking a hassle-free cleaning process. The improvement in the Revolve Extend variant addresses concerns about seat cover removal and enhances the overall user experience.
Both car seats come with shoulder harness pads to improve comfort during the ride. The Cybex Sirona S boasts 12 recline positions, allowing for flexible adjustment, while the Evenflo Revolve 360 offers four recline positions.
Parents looking for longevity in their investment will appreciate the 10-year expiration period for both car seats. Additionally, cup holders are included with both models, with the Evenflo offering the added convenience of two cup holders.
There is an approximately USD 100 price difference between The Cybex Sirona S and Evenflo Gold Revolve 360. The Cybex is more expensive.
For the added USD 100, you get:
- A higher rear-facing weight and height limits, by default
- More recline positions
Saving USD 100 with Evenflo Gold Revolve 360 will give you:
- A 360-degree swivel
- An option for an extended rear-facing weight limit by choosing the Revolve Extend or Gold Revolve Extend variants

Opting for the Evenflo Gold Revolve 360, specifically the Revolve Extend Variant, offers a compelling set of features at a budget-friendly price. This choice ensures a well-rounded and versatile car seat, providing excellent value for your investment. For a hassle-free experience, choosing the Revolve Extend version with the Quick-Clean cover is recommended, and omitting the Gold Revolve Extend to avoid any complications associated with the Sensorsafe technology.
