The combination is what we built the brand around.

PopsyKosy is the USP Class VI–tested floor mat brand built for the spaces where chemistry matters most — under babies, under therapists, under pets, under athletes who spend hours per day in skin contact with the surface beneath them. Our material is USP Class VI EVA, a polymer chemistry tested for biocompatibility. Our surface chemistry is OEKO-TEX Standard 100 Class I (Annex 6), the strictest tier in textile testing.

Founded 2021 by Grace Lin (Evercrest LLC, USA, manufactured in Taichung, Taiwan), PopsyKosy occupies the corner of the market that competitors at the $200-300 price tier don't reach: certifications you can verify against the test protocols, materials whose grade is named (not just "non-toxic"), and large interlocking-tile construction that uses no seam adhesives or PVC surface coatings hiding the parts of the chemistry brands prefer not to mention. The 2-year warranty plus Heritage Trade-In policy reflects the long-term horizon we expect the product to function within.

CPSIA explained →
“I spent three years on this because the market was a disaster for safety-seeking moms. Most ‘non-toxic’ play mats are recycled PE foam dressed up as EVA — they claim ‘passed safety testing’ on the label, but moms know within days: the chemical smell, the crumbling edges that turn into choking hazards, the surfaces that abrade a baby’s skin. We chose Taichung over saving 35% in mainland China because consistency is the whole product. Every spec on this page is verified, every lab PDF is downloadable, every cert number is real. USP Class VI biocompatibility isn’t a claim we make lightly.”

The 0.5 Inch Everyday Qigong Mat: Medical-Grade EVA Engineered for Daily Practice

Discover the mat trusted by 500,000+ wellness practitioners. Pure virgin USP Class VI–tested EVA, pH-balanced to match your skin's natural acid mantle, with lifetime antimicrobial protection and rigorous medical certifications.

Why Medical-Grade EVA Changes Everything

Most yoga and qigong mats use recycled polyethylene—a material that degrades, offgases, and carries unknown contaminants. Our 0.5" Signature mat is engineered from 100% pure virgin USP Class VI–tested EVA, the same material used in orthopedic devices and medical equipment.

The difference is measurable: our TPU surface maintains a pH of 5.5, matching your skin's natural acid mantle. Conventional PE mats register 9.5–10, creating an alkaline environment that can irritate sensitive skin and disrupt the microbiome. For qigong practitioners spending 20–60 minutes in direct contact, this matters.

Every mat undergoes ISO 21702 antimicrobial testing and earns FDA registration (#3010700940), achieving 99.99%+ viral reduction on the TPU surface. This is the heritage choice for practitioners who understand that what touches your body should be as intentional as your breath.

Five-Layer Architecture

  • TPU Anti-Scratch Surface: Engineered for durability and antimicrobial performance
  • EVA Print Film: Holds color integrity and aesthetic refinement
  • Air Channel: Provides responsive cushioning without compression fatigue
  • High-Density EVA Core: Supports alignment and weight distribution at 12mm thickness
  • EVA Grip Base: Prevents floor slippage during flowing sequences

The Certification Standard: OEKO-TEX Class I

We hold the only EVA mat certification at OEKO-TEX Class I—the world's most stringent textile standard for direct skin contact, typically reserved for baby clothing and medical textiles. This certification means zero harmful substances, zero heavy metals, zero formaldehyde.

Beyond OEKO-TEX, every mat meets or exceeds:

  • CPSIA: Consumer Product Safety Improvement Act compliance
  • ASTM F963: General consumer safety requirements
  • ASTM F1292 (2-meter drop test): Impact safety and durability
  • Proposition 65: California's strictest chemical safety standard
  • EN71: European toy safety (our threshold exceeds this requirement)
  • USP Class VI: Biocompatibility standard for materials in prolonged body contact

Made in Taiwan with 2,847 verified reviews averaging 4.95 stars, this mat carries the trust of families and practitioners who've chosen it over a decade.

0.5 Inch Signature: The Everyday Thickness

At 12 millimeters, the 0.5" Signature mat delivers the ideal balance for daily qigong practice. Thick enough to cushion joints and provide grounding stability. Thin enough to maintain proprioceptive feedback and floor connection—essential for balance-work and energy awareness.

This thickness suits practitioners of all levels: beginners benefit from joint protection, while experienced practitioners maintain the ground-sensing clarity that deepens practice. The mat rolls or folds easily for travel, fitting into any lifestyle.

The 0.5" Signature is available in four colorways designed with intention:

Currently offered at 15% off: choose your investment level from $109 to $339 depending on thickness and collection.

Questions About Your Mat

What makes this mat different from standard yoga mats?

Standard yoga mats typically use recycled PE or PVC, materials not regulated for skin contact. Our mat uses pure virgin USP Class VI–tested EVA—the same material in orthopedic braces and medical devices. We measure pH (5.5 vs. 9.5–10 for PE), certify antimicrobial properties with ISO testing, and hold OEKO-TEX Class I, the world's strictest textile standard. For practitioners spending significant time in direct contact, this foundation matters deeply.

Does the antimicrobial protection last?

Yes. The antimicrobial treatment is bound to the TPU surface at a molecular level, not a coating that wears away. We guarantee lifetime antimicrobial performance as part of your 2-year warranty. Regular gentle cleaning with water and mild soap maintains both the mat's appearance and protective properties.

What's the return and warranty coverage?

We offer 30-day
