Nuna EXEC Next Convertible Car Seat
Lower PFAS risk for primary structure, but foam and fabric treatments not publicly disclosed, request materials spec from Nuna before buying.
The Nuna EXEC Next is primarily foam, fabric, and rigid plastic, materials less commonly treated with PFAS than waterproof textiles or nonstick coatings. However, Nuna does not publicly disclose PFAS content or absence in this product.

Why this grade
Category baseline
furniture is a category where PFAS exposure is more common.
No PFAS disclosure
No public statement about PFAS in this product.
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 EXEC Next uses polyurethane foam padding, plastic shell housing, and polyester-blend fabric upholstery. Polyurethane foam is standard in car seats for impact absorption but may contain brominated or phosphorus-based flame retardants to meet federal safety standards (FMVSS 213). The fabric upholstery treatment (water/stain resistance, antimicrobial finish) is not publicly detailed by Nuna, leaving uncertainty about dyes, formaldehyde resins, or additional chemical coatings. Plastic shell components can leach plasticizers under heat exposure typical in parked cars.
The brand's record and disclosure
Nuna has not published detailed material safety data sheets or flame retardant chemical lists for this seat model. The brand holds no known certifications beyond mandatory FMVSS 213 compliance and has not issued public statements on PFAS, phthalate, or heavy metal testing. No major safety recalls specific to chemical hazards have been issued for the EXEC Next, though general design/harness recalls should be verified via NHTSA. Nuna's silence on material transparency is typical of the industry but represents a disclosure gap relative to leading competitors.
How it compares in its category
The EXEC Next sits mid-range in material transparency; brands like Clek and Graco have published restricted substance lists and third-party testing summaries, while many other mainstream seats (Chicco, Evenflo) match Nuna's limited disclosure. All convertible seats must pass the same flame-retardant burn test, so chemical composition varies by manufacturer choice rather than regulatory mandate. Cost and safety performance are competitive, but chemical accountability lags premium or eco-focused alternatives. This seat is not a safety outlier within its category, merely average in transparency.
If you buy it
Contact Nuna directly to request the Materials Declaration, flame retardant chemical name, and fabric treatment specifications before purchase or installation. Keep the seat out of direct sunlight when not in use to reduce off-gassing and plasticizer migration from the plastic shell in hot cars. Do not use aftermarket seat covers unless they are non-flame-retardant certified and breathable, as they can trap heat and alter seat function. Inspect the foam and fabric annually for tears or peeling; if degradation is visible, consider replacement earlier than the 10-year industry lifespan, as breakdown accelerates chemical leaching.
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.”
Flame retardants in polyurethane foam
Polyurethane foam padding in car seats typically contains brominated or phosphorus-based flame retardants to meet FMVSS 213. Specific chemistry is not disclosed by Nuna; brominated retardants carry potential bioaccumulation concerns, though exposure during normal use is low. Request the flame retardant chemical name and CAS number from Nuna.
Fabric dyes and finishing resins
Polyester-blend upholstery may be treated with formaldehyde-releasing resins for water/stain resistance or contain azo dyes, neither of which Nuna publicly discloses. Off-gassing risk is low in ventilated vehicle environments, but infants and toddlers spend prolonged time in contact with the fabric.
Plastic shell plasticizer migration
The rigid plastic housing (likely polypropylene or ABS) may contain phthalates or other plasticizers that can leach under sustained heat in parked vehicles. Migration risk increases in temperatures above 60 degrees Celsius (140 degrees Fahrenheit), common in closed cars during summer.
Coating or finish degradation over time
No published data on polyurethane foam or fabric durability under long-term exposure to vehicle heat, UV, moisture, and cleaning products. Degradation can expose underlying chemicals and create microfiber/foam particle shedding, particularly concerning for children with respiratory sensitivity.
Bacterial or mold growth in fabric and foam if wet
No recalls or field reports of microbial contamination in this model; however, polyurethane foam is moisture-absorbent and can retain humidity if not dried promptly after spills or rain exposure, creating conditions for mold or bacterial growth that is difficult to assess without disassembly.
What we don’t know
This grade is a model-based estimate from public materials, coatings, and brand disclosure at 62% 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.
