What Premium Yoga Cork Mat 5mm Extra Support is made of, ingredients and materials

This mat combines a natural tree rubber base with a cork surface layer. Natural rubber is a latex polymer extracted from rubber trees and does not require synthetic flame retardants or halogenated fire suppressants typical of petroleum-based foams. Cork is harvested bark from cork oak trees and is inherently antimicrobial and low-VOC. Both materials are biodegradable and do not off-gas formaldehyde or volatile organic compounds at room temperature, unlike many synthetic yoga mats (PVC, EVA foam, or polyurethane).

♾️

No PFAS disclosure

No public statement from the brand about PFAS in this product.

85/ 100
⚠️

Microbial growth (mold, mildew)

Natural rubber and cork are organic, porous materials that can support fungal growth if not dried promptly after use or stored in humid conditions. This is a maintenance issue, not a manufacturing defect, but untreated mats are more susceptible than chemically antimicrobial synthetics.

70/ 100
⚠️

Latex protein allergenicity

Natural rubber contains latex proteins that can trigger contact dermatitis or respiratory sensitivity in individuals with latex allergy. The risk is low for most users but non-negligible for the 1-3% of the population with latex sensitization; no hypoallergenic variant is marketed under this brand.

45/ 100
💨

Cork dust inhalation (minor)

Cork surface can shed fine particles with heavy use or if worn. Inhaling cork dust is not acutely toxic but may irritate respiratory passages in sensitive individuals; brushing or vacuuming the mat regularly minimizes this.

Heavy metals

No published third-party analysis of cadmium, lead, or arsenic in mats exists in public records. Cork and rubber are low-risk for heavy metal accumulation, but the brand does not voluntarily disclose testing data.

How is this PFAS grade calculated?

The brand's record and disclosure

The brand maintains a reputation aligned with traditional yoga practice and has no documented safety recalls or material disclosure controversies in public records. The brand does not publish detailed third-party certifications (e.g., Oeko-Tex, Cradle to Cradle, or heavy metals testing reports) on their website, which is typical for smaller yoga equipment manufacturers. Their silent stance on PFAS is consistent with the material choice; natural rubber and cork do not require water-resistant fluorochemical coatings.

How it compares in its category

Most budget yoga mats use PVC or EVA foam, which carry known flame retardant residues and formaldehyde off-gassing concerns. Synthetic rubber and polyurethane alternatives often incorporate antifungal chemicals and antimicrobial additives. Natural rubber and cork mats occupy the premium end precisely because they avoid these additives; the tradeoff is shorter lifespan and higher moisture sensitivity compared to chemically stabilized synthetics. This product uses materials with lower concern for PFAS but requires more active maintenance.

If you buy it

Store the mat in a dry, ventilated area; cork and rubber are porous and can harbor mold or mildew if kept damp. Clean with mild soap and water after sweaty sessions, and air dry fully before rolling. Do not expose to direct sunlight for extended periods, as UV degrades natural rubber over 2-3 years of heavy use. Replace when the cork surface flakes significantly or rubber loses grip, typically 3-5 years with regular care.
