Cybex Sirona S Review 2023

Cybex Sirona S crash test
The Cybex Sirona S performed better than average for crash test results. It delivered an impressive performance for head sensor result (HIC) scores but less excellent results for chest clips than the competition. Like all other seats sold in the United States, it has a basic level of protection and meets federal standards for car seat safety.
The chest sensor result on the Sirona S is 50, with a maximum acceptable result of 60. Lower results are better. The group’s lowest and, therefore, the best result is 33 for Clek Foonf.
The Sirona S head sensor (HIC) result is 231, with 1000 being the best in the group, well below the maximum acceptable value. Britax Allegiance has the best results for this metric, with 186.
The load leg of the Sirona S has a color change indicator, while the load portion has a color change indicator.
Additionally, this Cybex Sirona features side impact protection, anti-bounce protection, and rod legs to help absorb the impact in the event of a crash. How well this work is anyone’s guess, and crash tests on seat types have shown that road legs help some seats and not others.
Comfortable with a good quality
The Sirona S gets top marks for comfort and quality in this review. These seats are also one of the most expensive options. This Cybex uses EPP foam for shock absorption. This type of foam is brittle and a bit more environmentally friendly.
The Cybex padding is superior to the competition and provides firm, supportive comfort. The fabric feels softer and friendlier than other convertible seats we’ve reviewed. It has a very dense weave that wears well over time and helps clean up messes more easily.
The foam fits the frame nicely, and the fabric looks tailored without being harsh. The shell is enclosed so you can manage it more neatly, giving a smooth and high-quality feeling. The seat bottom is not soft, and the protrusions are rounded to help protect the vehicle seat.
The Sirona S LATCH installation differs from most competitors in that it still requires a belt locking system that works with the vehicle’s belt installation. Most seats do not use a belt lock for LATCH anchor installation.
Sirona’s LATCH connector features a push button and a pull button. The belt passage is accessible from under the compartment door. It’s easy.
The LATCHEs are unlike anything else, with large push buttons and the odd red pull strap. It’s not difficult to use, but I’m unsure if the changes make it better than the average LATCH.
However, in theory, this seat only needs to be installed once. The oddity of the LATCH anchor may not be a big deal, as the hub rotates on the base when ready to move into a forward-facing position.
Sirona belt installation is not as simple as the non-impact LATCH method. Cybex has a removable cover on the belt path. This is useful because the car seat is held out of the way while belting when the body is off. The seat rotates to access the belt path, which is better than needing threads behind the seat padding.
The belt unlock compartment is easy to open and slides into place easily. However, I still had to tighten the strap to make it feel secure before sliding the belt tensioner into place. So while the straps are excellent and essential to installing seatbelts, this wasn’t as effective at keeping the straps as tight as the competition.
The cover of Cybex Sirona S SensorSafe is removable and machine washable in cold water. Easy to remove and replace after air drying, but a tool may help put the edges back together.
The Sirona seat belt is a non-re-adjustable height adjustment device that moves with the headrest and can be performed with the baby seated. There are nine shoulder strap positions and three crotch strap positions.
The assembly moves pretty smoothly, but it’s a bit more complex than some of the competition, as the handle is somewhat hidden, and you have to pull the headrest up before moving it.
The angle of the Sirona S can be adjusted after seat installation. Sirona S’ level is easy to use and works well. Angle adjustment is possible after installing the Sirona, which is rare for a convertible seat. There is a working metal ball level indicator on the base.
The Sirona S’s chest clip is more challenging than most of its competition, as you must press a button to open and close it. When prompted, the buckle is stiff but begins with spring action, making the stiffness more tolerable. The most troublesome thing in this whole operation is the chest clip.
The chest clip has a small button on the front that you must press to attach the two sides and when you want to remove it. It makes the whole process rather cumbersome, and we can see this being unpleasant with a tiny toddler in a seat.
The pull straps to tighten the harness are very long and work well. The release button is bottomless but easy to press and works smoothly.
Weight and wide
This Cybex Sirona S weighs 30 lbs in front or rear configuration. This is one of the heaviest options in the group, and we recommend it for anyone who needs to move from car to car or haul long distances frequently.
This Cybex is 19 inches wide at its widest point. While this makes it quite large, it’s no contest for the broadest seat in our review.
This width is only an issue if you want more than one car seat or two-person seat in a row and an adult passenger between them. This may not be the best choice if you plan to use multiple.
