When considering car seats for your child, dimensions play a crucial role in determining whether the seat will fit securely and comfortably in your car. 

The Evenflo Revolve 360 Slim boasts a width of 16.75 inches, a height of 24.3 inches, and a depth/length of 21 inches. In contrast, the Cybex Sirona S presents bigger dimensions, featuring a seat width of 19 inches, 24 inches in height, and a length extending to 30 inches.

For parents with limited space in their vehicles, the more compact dimensions of the Evenflo Revolve 360 Slim may be an appealing feature. Its narrower width is particularly advantageous in cars where space is at a premium. Additionally, the shorter depth can benefit vehicles with smaller backseat areas.

On the other hand, the Cybex Sirona S is a bit bigger, but it could be better for parents who want more room in the car. The wider seat gives extra comfort; the longer part can be helpful if you like a seat that leans back more. The Cybex one works well in cars with a lot of space in the back.

The Evenflo Revolve 360 Slim is noted for its straightforward installation process in both rear-facing and forward-facing positions. Users generally find it easy to install and uninstall, especially when using the seatbelt for installation. 

Some users find the LATCH tips on the Evenflo Revolve 360 Slim less convenient than the original 360 model. Getting a secure installation can be challenging depending on the type of car as some users need help with the bottom tether.

On the other hand, the Cybex Sirona S presents some challenges during installation. Parents suggest threading the belt's tail back through and applying firm pressure from behind to eliminate wobbling. 

While online guides are available, recent feedback on installing the Cybex Sirona S with SensorSafe has been overwhelmingly negative. Parents express frustration with difficulties securing LATCH attachments, challenges with the rotation function, and concerns about the seat's stability, even after repeated attempts.

It's crucial to note that the headrest is not a reliable reference for tightness; users are advised to check the car seat's belt path, ensuring minimal movement within an inch.

The Cybex Sirona S, incorporates several safety features, including a notable load leg that extends to the vehicle floor, distributing crash forces away from the child. The anti-rebound design reduces movement toward the vehicle's rear during a crash, minimizing crash forces on the occupant. The Linear Side Impact Protection (L.S.P) feature shields the child from side impact forces. 

Additionally, the Cybex seat integrates Cybex SensorSafe 4-in-1 Safety Kit, connecting to a smartphone to provide alerts on critical situations such as a child left unattended or unbuckling. 

However, user feedback indicates dissatisfaction with the Cybex floor anchor's effectiveness.

Similarly, the Evenflo Revolve 360 Slim prioritizes safety with a steel-reinforced frame and rigorous testing to meet or exceed federal standards. 

The "Gold Revolve Slim" variant includes the Sensorsafe system, integrating an intelligent sensor into the harness. While aiming to enhance safety, user reviews reveal mixed opinions. Some users report reliability issues, including false alarms indicating a child left in the car when that is not the case. 

The accompanying app of the Evenflo Sensorsafe has also faced criticism for occasional bugs and inaccurate temperature alerts. 

While the Cybex Sirona S is not approved for airplane use, it's worth noting that the Evenflo Revolve 360 Slim has received approval, making it a suitable choice for families who frequently travel by air.

Moreover, as reported by users, both car seats encounter challenges in the buckling and unbuckling process of the 5-point harness.

It's noteworthy that the Cybex Sirona S is constructed with EPP foam. In contrast, the Evenflo Revolve 360 Slim is made with EPS.

Expanded Polypropylene (EPP) and Expanded Polystyrene (EPS) are both types of foam commonly employed in constructing car seat energy-absorbing components. They are designed to absorb and dissipate impact forces in the event of a collision, thereby enhancing the child's overall safety within the seat.

EPP foam, used in the Cybex Sirona S, is known for its resilience and durability. It is often characterized by its ability to recover its shape after impact, making it a reliable choice for absorbing and distributing crash forces. The use of EPP foam in the Cybex Sirona S suggests a focus on providing robust protection in the face of unexpected events.

On the other hand, the Evenflo Revolve 360 Slim incorporates EPS foam. EPS is a lightweight yet practical material that absorbs energy during a crash. It is widely used in the automotive industry for its ability to cushion and reduce impact forces. While it may not be as resilient as EPP, it offers commendable safety features.

In comparing these foam materials, it's important to note that the effectiveness of a car seat's safety features goes beyond the specific type of foam used. The overall design, engineering, and compliance with safety standards contribute significantly to the protective capabilities of the car seat.

The Evenflo Revolve 360 Slim features a convenient swivel mechanism for seamless transitions between rear-facing and forward-facing positions. In contrast, the Cybex Sirona S utilizes a tether to secure the seat when facing forward, preventing rotation and emphasizing safety in this mode. This means that, due to the tether, the Sirona cannot rotate in the forward-facing position.

Both models boast breathable materials, ensuring comfort during extended rides. Considering the weight, the Evenflo Revolve 360 Slim is lighter at 28.5 pounds, making it a slightly more manageable choice compared to the Cybex Sirona S, which weighs 30.4 pounds.

The machine-washable cover feature is common to both, simplifying cleaning and maintaining hygiene. However, the Evenflo Revolve 360 Slim's Quick Clean Cover variant stands out. It provides an efficient solution for parents looking to maintain cleanliness easily.

Regarding spaciousness, both car seats offer a roomy design, prioritizing the child's comfort during travel. The no-rethread harness feature in both models adds convenience for parents, allowing for easy adjustment as the child grows.

An essential aspect for parents to consider is the expiration date, and both models offer a generous lifespan of 10 years. This ensures long-term use and value for the investment.

Cup holders are a practical consideration for parents, and here, the Evenflo Revolve 360 Slim takes the lead by providing two cup holders compared to the Cybex Sirona S's single cup holder.

The Evenflo Revolve 360 Slim and the Cybex Sirona S have notable differences in their recline positions. While the Evenflo model provides four positions, the Cybex counterpart surpasses it with an impressive twelve, offering a broader range of options to cater to the child's comfort and safety.

My Final Verdict


There is an approximately USD 200 price difference between the Evenflo Revolve 360 Slim And Cybex Sirona S. The Cybex Sirona S is more expensive.

With the Cybex Sirona S, you get a

  • slightly higher rear-facing height limit (but only 1 inch more)
  • a seat that is jampacked with safety features
  • a seat has EPP foam instead of EPS
  • more recline positions

With the Evenflo Revolve 360 Slim, you get

  • a more compact seat
  • a complete 360-degree swivel feature
  • car seat that is effortless to install and uninstall across all modes of use.
  • a slightly lighter seat
  • an approval for airplane use
  • an optional "Quick Clean" cover
  • an extra cup holder

The Evenflo Revolve 360 Slim, especially the version without Sensorsafe, is a practical, budget-friendly choice that maintains essential safety features. Choosing the Quick Clean cover or the standard Revolve Slim variant ensures a user-friendly design, compactness, and added conveniences. It's a well-rounded option for families seeking a reliable car seat without unnecessary hassles.
