Clek Oobr Booster Seat
Lower PFAS concern; standard booster seat without obvious high-risk coatings, but brand offers no transparency.
The Clek Oobr is a rigid polypropylene booster seat without obvious stain-resist or water-repellent treatments commonly associated with PFAS. Clek has not publicly disclosed PFAS policies or testing, which limits confidence.

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 Oobr shell is polypropylene plastic with polyurethane foam padding, both common in car seats. Polypropylene is a relatively stable thermoplastic that does not leach BPA or phthalates under normal vehicle temperatures. The foam padding is a potential source of off-gassing of volatile organic compounds (VOCs) during initial use, particularly in hot vehicles, though this typically diminishes within days to weeks. No lead, cadmium, or azo dyes are known to be used in the construction.
The brand's record and disclosure
Clek is a well-regarded specialty booster seat manufacturer with a reputation for engineering and safety focus, but the company does not publish detailed material safety disclosures or third-party chemical test results on their website. The brand has not faced documented chemical safety recalls or controversies in the public record. Clek does not explicitly address PFAS in its material sourcing or flame retardant statements, leaving the full chemical profile opaque.
How it compares in its category
The Oobr is positioned as a premium, lightweight backless booster in a market segment that includes brands like Graco, Britax, and Evenflo, most of which use similar polypropylene and polyurethane construction. Clek's engineering reputation and German design heritage differentiate it on durability, but it does not stand out chemically; most boosters in this category carry similar baseline plastic and foam hazard profiles. It is not specifically marketed as low-chemical or non-toxic, which may appeal to parents seeking transparency but does not necessarily mean higher chemical risk than competitors.
If you buy it
Air out the seat for 24-48 hours in a well-ventilated space before first use to reduce initial VOC off-gassing, especially if purchasing in warm months. Do not cover or store the seat in direct sunlight for extended periods, as heat can accelerate foam degradation and minor plastic off-gassing. Inspect the plastic shell and seams annually for cracks or peeling, which could allow foam exposure or seat compromise. Clean with mild soap and water; avoid harsh solvents that may degrade the plastic or foam.
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.”
VOC and polyurethane foam off-gassing
Polyurethane foam padding may release volatile organic compounds, particularly in the first days after purchase or when exposed to heat. This is a recognized characteristic of foam in booster seats generally, not unique to Clek, and typically resolves with ventilation.
Polypropylene plastic degradation over time
Prolonged UV exposure and temperature cycling in vehicles can cause brittleness and surface cracking in polypropylene shells. This is a durability and functional safety concern rather than an acute chemical risk, but compromised plastic may allow foam contact.
Flame retardant chemicals (unspecified)
Booster seats are not required to meet the same flammability standards as car seats, and no public documentation indicates whether the Oobr foam or shell contain added brominated or organophosphate flame retardants. Clek has not disclosed the flame retardant status or chemistry.
BPA and phthalates in plastic
Polypropylene does not naturally contain BPA, and modern booster seat manufacturers rarely add phthalates to PP; no recalls or tests have flagged these chemicals in the Clek Oobr specifically.
Heavy metals in dyes or coatings
The Oobr's simple molded plastic construction and printed graphics do not match the high-risk profile for lead or cadmium contamination seen in some ceramic or painted children's products. No testing data or recalls reference heavy metal contamination.
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.
