Prosource Premium 1/2-inch Extra Thick 71-inch Long High Density Exercise Yoga Mat with Comfort Foam and Carrying straps
Lower concern mat; no PFAS indicators identified in standard yoga mat materials.
Exercise mats typically use closed-cell foam or natural rubber without PFAS additives. ProSource provides no PFAS disclosure, but standard yoga mat compositions pose minimal risk.

What Prosource Premium 1/2-inch Extra Thick is made of, ingredients and materials
This mat is constructed from closed-cell foam (likely ethylene-vinyl acetate or EVA) bonded to a nitrile rubber (NBR) base. Closed-cell foam is a dense, non-porous polymer that resists water absorption and bacterial colonization better than open-cell alternatives. NBR rubber is a synthetic elastomer chosen for durability and slip resistance. Neither material is known to leach significant quantities of heavy metals or regulated plasticizers under normal use conditions, though both can off-gas volatile organic compounds (VOCs) when new.
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
New closed-cell foam and NBR rubber products typically emit trace VOCs (styrene, benzene precursors, or formamide from binding agents) for the first few days to weeks. ProSource does not disclose VOC testing or off-gassing limits; ventilation during initial use is recommended.
Bacterial or mold growth from moisture retention
Closed-cell foam resists water absorption, but the carrying strap attachment points and seams may trap moisture if the mat is not dried thoroughly after cleaning or storage in humid conditions. Regular air-drying is the primary mitigation.
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 documented formaldehyde content or emissions have been reported for ProSource yoga mats. However, foam-to-rubber adhesives in budget-to-mid-range mats may contain low-level formaldehyde-releasing resins; independent testing would be required to rule this out for this specific product.
Source, ATSDR ↗Flame retardants
Exercise mats are not typically treated with brominated or chlorinated flame retardants, as they are classified as non-upholstered soft goods with lower regulatory exposure. No flame retardant content has been reported for ProSource mats.
Source, EPA ↗Phthalates
NBR rubber and closed-cell EVA foam do not inherently require phthalates for flexibility. No recalls or identified phthalate contamination exist for ProSource products, though full material composition is not disclosed.
Source, ATSDR ↗The full breakdown
The brand's record and disclosure
ProSource is a mid-market fitness equipment brand with no documented recalls, FDA warnings, or third-party certifications (such as Greenguard or OEKO-TEX) on file for this mat. The brand does not publicly disclose material sourcing, manufacturing standards, or chemical testing results. No formal environmental or safety statements have been found in available sources. Absence of disclosure does not indicate hazard presence, but limits independent verification of manufacturing controls.
How it compares in its category
Closed-cell foam mats like this one are standard in the exercise mat market and generally carry lower volatile off-gassing risk than open-cell memory foam or latex alternatives. Premium yoga mats often add natural rubber or cork veneers; this product opts for synthetic durability over bio-based materials. Thickness (1/2 inch) and density claim sit in the mid-to-high range, which typically correlates with longer product life and lower replacement frequency, reducing cumulative exposure risk.
If you buy it
Air out the mat in a well-ventilated space for 24 to 48 hours before first use to reduce new-product VOC off-gassing. Clean regularly with a damp cloth and mild soap; avoid harsh solvents that can degrade the foam or rubber. Store in a cool, dry location away from direct sunlight to slow material breakdown and odor development. Replace if the foam becomes sticky, flakes, or develops persistent odor that does not fade within a few months, as this may indicate accelerated polymer degradation.
