The Cybex Sirona S boasts a rear-facing weight limit range of 4 to 50 pounds and a height limit of 49 inches. The Evenflo Gold Revolve 360 offers a rear-facing weight limit of up to 40 pounds and 40 inches. Therefore, if you need a car seat with the capability to accommodate larger children in the rear-facing position, Cybex Sirona S is the better choice.

For forward-facing weight and height limits, both car seats offer very similar capabilities with up to 65 pounds for weight and up to 49 inches in height. 

The Cybex Sirona S does not have a high back booster option. The Evenflo Gold Revolve 360 has one from 40 to 120 pounds and 44 to 57 inches in height. Thus, if you plan on using your car seat as a high back booster too, then you should go for the Evenflo Gold Revolve 360.

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


When it comes to size, both options are quite 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 measures 21 inches.

If you have limited space in your vehicle, then the Evenflo Gold Revolve 360 might be the better option due to its smaller length.

Consider narrowing down your options by focusing on those made with EPP or EPS foam for impact management. Both materials meet government safety regulations, but EPP foam is more elastic and less brittle than EPS foam, making it better at withstanding multiple impacts and regaining its shape.

Keep in mind that any seat involved in an accident should be replaced, regardless of the foam type.

Do I need to use a pool noodle/rolled towel?

No

Easy To Install Rear-Facing 

Yes

Easy To Install Forward-Facing?

Yes

Easy To Uninstall?

Yes


The Cybex Sirona S and the Evenflo Gold Revolve 360 are both easy to install, either rear-facing or forward-facing, and easy to uninstall if needed. 

Some parents have reported that the “main seat” of both Cybex Sirona S and Evenflo 360 feel wobbly and not secure after installation.

To ensure proper installation, testing should only be done on the belt path. Testing from another part of the seat may give an inaccurate indication and cause excessive movement.

Even if you experience some wobbling at the top, this doesn't mean it's improperly installed as long as there is no more than 1 inch of movement when testing on the belt path.

The Cybex Sirona S and the Evenflo Gold Revolve 360 are made in China and feature a steel-reinforced frame. Both car seats are not approved for airplane use.

When compared to the Evenflo 360, adjusting the five-point harness straps on the Cybex Sirona S is a breeze. The straps are much easier to handle and don't take as long to adjust properly.

While both seats are packed with safety features, the 5-point point harness of the Cybex Sirona S has an added feature - SensorSafe 4-in-1 Safety Kit. To further ensure your child's safety, connect the included SensorSafe 4-in-1 Safety Kit to your smartphone after securing them in the car seat. This will alert you to potential hazards such as if the child has been left alone in the car, temperatures becoming too cold or hot, them unbuckling their clip, or sitting for too long.

The Cybex Sirona S and Evenflo Gold Revolve 360 are both quite heavy. The Cybex car seat weighs in at 30.4 pounds, while the Evenflo car seat is 29.6 pounds.

Compared to the Cybex car seat which has little to no complaints about its seat cover being difficult to remove for washing, the Evenflo 360's seat cover is reported to be relatively harder to take off. 

The Cybex car seat has one cup holder, while the Evenflo offers two.

Cybex provides a generous recline positions of 12, compared to Evenflo's 4 recline angles.

The handle of the Evenflo headrest can be a source of frustration for some parents, as it rattles quite a bit. Evenflo claims that this is normal, though it can still be bothersome.

My Final Verdict


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 limit
  • A higher rear-facing height limit
  • A 5-point harness that is easier to buckle and unbuckle
  • A 5-point harness with an extra safety feature
  • A seat cover that is easier to remove for washing
  • More recline positions

Saving USD 100 with Evenflo Gold Revolve 360 will give you:

  • A highback booster seat of up to 57 inches and 120 pounds
  • A more “compact” seat due to its length
  • A slightly lighter seat
  • An extra cup holder

The Cybex Sirona S and the Evenflo Gold Revolve 360 are both great car seats to consider for families with young children. Both offer excellent safety and comfort features, but they do have some differences that may make one of them a better choice for your family.
