Cybex Solution Z-Fix Booster Car Seat
Lower concern; standard car seat materials carry minimal PFAS risk, but Cybex does not publicly disclose.
The Cybex Solution Z-Fix is a booster seat made primarily from polypropylene plastic and polyurethane foam with textile covers, materials not typically associated with intentional PFAS use. Cybex makes no public PFAS disclosure or claims. No third-party PFAS testing or recalls are documented for this model.

Safe base material
Made from a material with no inherent PFAS use (ceramic, mineral, or natural fiber).
The full breakdown
What it's made of and why it matters
The Cybex Solution Z-Fix shell is polypropylene, a thermoplastic polymer chosen for impact absorption and lightweight structure in crash scenarios. The foam padding (typically polyurethane or expanded polystyrene) provides cushioning during deceleration. Textile upholstery covers both materials; this construction is industry-standard for booster seats and does not involve glazes, enamels, or coatings prone to heavy-metal leaching that affect cookware or ceramics. No Teflon-type coating (Teflon) or similar non-stick coatings are present, eliminating fume-release risk under heat.
The brand's record and disclosure
Cybex is a German-owned manufacturer with strong European safety certifications (ECE R44/04 and R129 approval) and a track record of compliance with EU and US child safety regulations. The brand does not publicly disclose PFAS content in booster seats, consistent with broader industry silence on this topic in child car seats. No major recalls or safety controversies specific to the Solution Z-Fix have been recorded in US NHTSA or CPSC databases. Cybex markets this as a mid-range product with emphasis on impact protection rather than premium material transparency.
How it compares in its category
Booster seats as a category use standardized polypropylene shells and polyurethane foams; the Solution Z-Fix follows this norm and does not employ unusual material combinations. Compared to high-end boosters (e.g., some Britax or Graco models with leather or advanced composites), the Cybex uses conventional textiles without specialty coatings, reducing chemical leach potential. Relative to budget boosters, Cybex maintains stronger structural certification standards. Material-wise, it sits comfortably within the safety baseline of the booster-seat market.
If you buy it
Keep the seat away from prolonged direct sunlight and excessive heat (above 65C/150F), as polypropylene can soften and foam can degrade over time. Wash upholstery according to manufacturer guidelines using mild soap; avoid harsh solvents that could compromise fabric integrity. Inspect the shell monthly for cracks, especially after collisions or drops, as impact damage may compromise crash protection. Replace the entire seat if it has been in a moderate or severe vehicle crash, per NHTSA guidance; foam padding is non-replaceable in this design.
Beyond PFAS: other things we checked
Established hazard classes for this product type, assessed from public information. These never change the PFAS grade; a Likely flag caps the Verdict at “Buy with care.”
Polypropylene shell degradation under UV and heat
Polypropylene can become brittle or warp with prolonged sun exposure or heat above 60C. Regular sunshade use and storage in cool vehicles minimizes this risk in normal household use.
Polyurethane foam off-gassing (VOC/formaldehyde)
Expanded polyurethane foam may release volatile organic compounds and trace formaldehyde during manufacturing and early use, particularly in warm environments. This is typical across the booster-seat category and diminishes after initial weeks of airing.
Textile upholstery: formaldehyde resins and azo dyes
Standard child-seat fabrics may contain formaldehyde-based finishing resins or reactive dyes. Cybex does not disclose fabric pre-treatment specifics. OEKO-TEX or similar certification is not advertised, leaving uncertainty on chemical residues.
Antimony in polyester components
If the upholstery contains polyester (common in affordable boosters), antimony compounds may be present as catalysts. No public disclosure from Cybex on polyester sourcing or antimony content for this model.
Microplastics and particle shedding from foam
Degraded polyurethane or expanded foam can shed fine particles with extended use or abrasion. Direct child skin contact is limited due to upholstery covering, but inhalation risk is low under normal conditions.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 72% confidence. It is not a lab result.
No independent PFAS lab test is on record for this exact product. A lab test could move the score in either direction.
The brand has not made a specific, verifiable PFAS-free statement, so part of this score reflects that missing disclosure rather than a confirmed material.
Formulations and coatings change between production runs. Always check the current label before buying.
