lululemon The Mat 5mm Made With FSC Certified Rubber
Lower concern yoga mat; rubber unlikely PFAS source but no brand disclosure.
Natural rubber yoga mat with FSC certification offers lower PFAS concern. Lululemon provides no PFAS statement, but material itself is not a typical vector for these chemicals.

What lululemon The Mat 5mm Made With FSC is made of, ingredients and materials
This mat is constructed from FSC-certified natural rubber, a plant-derived elastomer that does not require synthetic chemical processing typical of PVC or closed-cell foam alternatives. Natural rubber's inherent elasticity and durability mean it resists coating degradation and does not depend on volatile off-gassing adhesives or flame retardant treatments. The 5mm thickness provides adequate cushioning for yoga and pilates without need for supplementary chemical stabilizers. FSC certification indicates the rubber source was harvested from sustainably managed forests, though this does not address processing chemicals downstream.
What’s concerning
Category baseline
The starting point for this type of product, before anything specific to this product is counted.
No PFAS disclosure
No public statement from the brand about PFAS in this product.
Volatile organic compound (VOC) off-gassing from natural rubber
Natural rubber may emit terpenes and other volatiles during manufacturing residue outgassing, especially in the first days of use or if stored in warm conditions. This is generally mild and subsides quickly but may be noticeable in poorly ventilated spaces or for chemically sensitive individuals.
Rubber degradation and microparticle shedding over time
Natural rubber mats can crack, flake, or shed microparticles as the elastomer ages, particularly if exposed to UV, ozone, or heat. This is a material property of rubber and not specific to Lululemon but increases with product age and poor storage conditions.
What’s reassuring
Base material not linked to PFAS
The main material recorded for this product is not one associated with PFAS.
Formaldehyde / VOCs
No evidence that Lululemon uses formaldehyde-releasing resins or treatments on The Mat. Natural rubber does not require such additives for structural integrity, though processing additives remain unverified by brand disclosure.
Source, ATSDR ↗Flame retardants
Natural rubber does not typically require halogenated or phosphorus-based flame retardants; FSC rubber certification does not explicitly exclude them but no reports or brand statements indicate their use in The Mat.
Source, EPA ↗Heavy metals
No recalls or testing reports link Lululemon's rubber mat to lead, cadmium, or other heavy metals. Natural rubber sourced from established plantations carries lower contamination risk than reclaimed rubber products.
Source, FDA ↗The full breakdown
The brand's record and disclosure
Lululemon does not publicly disclose full material testing or chemical audit results for The Mat, nor does the brand make PFAS statements or publish restricted substance lists. The company has faced no major safety recalls or lawsuits specific to yoga mat composition. Lululemon markets the product on sustainability and performance rather than chemical safety transparency, which is typical for apparel and gear brands but limits independent verification of manufacturing practices.
How it compares in its category
Natural rubber mats generally carry lower flame retardant and heavy VOC concerns than PVC, TPE, or polyurethane foam alternatives, which often require chemical treatments or emit formaldehyde during curing. However, natural rubber may off-gas volatile organic compounds (primarily terpenes) during first use or storage in heat; this is distinct from synthetic resin off-gassing and typically mild. Compared to branded TPE or closed-cell foam mats, The Mat's rubber composition avoids reported phthalate and flame retardant exposures associated with budget PVC mats.
If you buy it
Unroll the mat indoors in a well-ventilated space for 24-48 hours before first use to allow any initial terpene off-gassing to dissipate. Clean with mild soap and water; do not expose to heat sources, direct sunlight for extended periods, or harsh solvents, as natural rubber can degrade or become sticky. Replace if cracking, flaking, or surface degradation develops, typically after 2-3 years of regular use depending on storage conditions. Store rolled in a cool, dry location away from ozone sources (e.g., air ionizers) and UV exposure.
