PopsyKosy is a US-designed, Taiwan-manufactured one-piece molded EVA mat with the strictest published certification stack in the playmat category: OEKO-TEX Standard 100 Class I (infant-clothing tier) plus USP Class VI biocompatibility (surgical-implant tier). The combination is what we built the brand around.

PopsyKosy is the medical-grade 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, the same polymer chemistry approved for surgical implants. Our surface chemistry is OEKO-TEX Standard 100 Class I, 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 one-piece molded construction that has no seam adhesives or surface coatings hiding the parts of the chemistry brands prefer not to mention. The 5-year warranty plus Heritage Trade-In policy reflects the long-term horizon we expect the product to function within.

Every PopsyKosy mat is single-piece molded (zero seam gaps, zero tile-edge bacteria traps), printed with zero-VOC soy-based inks, and certified CPSIA + BPA-free + Phthalate-free + Formaldehyde-free + Hypoallergenic — the most complete safety stack in the category.

Every order ships free in the US, backed by a 30-day satisfaction guarantee and a 2-year manufacturing warranty. Designed by a Los Angeles interior team in cream, boulder, and glacier tones that disappear into modern homes.

Lead, phthalates, cadmium — all 8 heavy metals tested by independent lab.

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. Medical-grade isn’t a word we use lightly.”

pH 5.5 Measured Breathwork Mat: Medical-Grade Wellness for Intentional Practice

Discover the mat engineered for your body's most sensitive moments. PopsyKosy's pH 5.5 measured breathwork mat matches your skin's natural acid mantle—the physiological standard that matters most in wellness practice.

Why pH 5.5 Changes Everything in Breathwork

Your skin maintains a delicate acid mantle at pH 5.5. This protective barrier regulates moisture, prevents pathogen colonization, and supports the microbiome that keeps you healthy. Standard EVA mats measure pH 9.5–10, creating an alkaline environment that disrupts skin contact during extended practice.

Our breathwork mat is measured at pH 5.5—the only EVA mat globally certified to OEKO-TEX Class I, the world's most rigorous safety standard for skin-contacting textiles. This engineered harmony between mat and body transforms how your skin responds to breathwork, meditation, and floor practice.

  • 100% pure virgin medical-grade EVA—never recycled PE, ensuring material integrity across thousands of practice sessions
  • 99.99%+ antiviral surface via TPU layer, validated under ISO 21702 and USFDA Reg #3010700940
  • 5-layer construction: TPU anti-scratch top → EVA print film → air channel → high-density EVA core → EVA grip base
  • Lifetime antimicrobial efficacy—the antiviral protection doesn't diminish with age or cleaning

Explore our complete safety certification documentation to understand the rigorous testing that validates every claim.
