Cybex Sirona S
Cybex Sirona S is listed here as a convertible with a value score of 33. Its lowest catalog price is from $529, and that figure is a labeled sample until Amazon’s Creators API or legacy PA-API replaces it. Any spec marked Manufacturer was read from the cited page on the date shown; everything else stays Unverified, and none of this is a safety rating.
Rotating convertible. The NHTSA file has a Sirona M row; this page matches only the Sirona S phrase, so that older row does not attach here.

Questions people ask
What is the Cybex Sirona S?
Cybex Sirona S is a convertible in the Foldbench catalog. The summary on this page describes how it is sold. It is not a safety endorsement.
How much does the Sirona S cost on Foldbench?
The lowest price shown is from $529. If the row says Sample, it is not a live Amazon price. Live Amazon prices come only from the Creators API or legacy PA-API.
Is the Sirona S value score a safety rating?
No. The value score is 33. It compares shopping features with price. Foldbench does not publish a crash-safety score.
Does Foldbench say the Sirona S has been recalled?
Only when a child-restraint row in NHTSA’s post-2010 file matches this make and model phrase. A match is a name match. No match is not a clean bill of health. Check the model number and manufacture date.
Where do the Sirona S specs come from?
Each spec row is Unverified or Manufacturer. Manufacturer rows link the page that was read and the date it was checked. Unverified rows were not confirmed on a maker page.
Specs in this catalog are unverified seed values. Prices are samples until a live provider writes a price. Do not install a car seat from these numbers.

NHTSA recall check
Matched against child-restraint rows (record type C) in NHTSA’s post-2010 flat file, checked Oct 30, 2026. A match is a make and model-name match. It can miss a model number or include an older production run. It is not a certification that a seat is clear, and it is not a statement that your exact unit is recalled.
No child-restraint rows matched Cybex Sirona S. That is not a clean bill of health. Search NHTSA with the model number and the manufacture date on the label.
Foldbench does not copy NHTSA ease-of-use stars. Open NHTSA and look up Cybex Sirona S by the model number on your label. Ease-of-use ratings are about labels, instructions, and installation features. They are not crash-test scores. Foldbench’s own “day-to-day ease” number is a separate shopping formula.
