"USP Class VI-tested" is the most abused word in flooring marketing. The actual regulatory standard is USP Class VI — a multi-stage biocompatibility battery used to qualify medical-device-grade polymer chemistry. PopsyKosy's EVA passes that battery; most consumer foam mats are not tested at that tier because the testing costs $40-80K and takes 18 months.

"USP Class VI-tested" gets used by every consumer brand. The actual regulatory standard is USP Class VI: a six-stage biocompatibility battery (acute systemic, intracutaneous, intramuscular, mouse, rabbit, and chronic) that the polymer chemistry must pass to qualify medical-device materials. Most foam mats are not tested at that tier because the testing costs $40-80K and takes 18 months.
PopsyKosy's foam is rated USP Class VI — a standard used to qualify medical-device materials. Combined with OEKO-TEX Standard 100 Class I (whole product (Class I); the strictest textile-chemistry tier, originally written for items in skin contact with infants under 3), this means the surface is certified at thresholds that exceed FDA food-contact regulation. The relevance for daily use: zero compromise in skin-contact safety regardless of duration, sweat exposure, or pet interaction.

zero-VOC soy-based inks, and certified

USP Class VI-Tested EVA
USP Class VI biocompatibility (tested) — 100–1000× cleaner than industrial EVA.
“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.”

FDA Cleared
FDA approval for a medical device; PopsyKosy is NOT FDA-cleared because the mat itself is not a medical device — only the polymer chemistry passes USP Class VI testing.
GREENGUARD Gold
A low chemical-emission certification; PopsyKosy holds the stricter OEKO-TEX Standard 100 Class I.
Prop 65
California Proposition 65 — requires warning labels for products containing chemicals known to cause cancer or reproductive harm; PopsyKosy is compliant.
The PopsyKosy mat is built from 100% virgin, USP Class VI–tested EVA — a biocompatibility standard that originated in medical-device manufacturing — with a near-neutral measured surface pH of 6.5–7.0 and a smooth, non-porous TPU top layer that wipes clean in seconds. It's engineered for babies and toddlers, where a safe, easy-to-clean surface matters most.
What Makes the Material Different
Many bargain mats are made from recycled polyethylene that can run alkaline and trap odor. PopsyKosy uses a virgin EVA core with nothing carried over from previous industrial use, finished with a wipe-clean TPU surface so spills sit on top instead of soaking in. The five-layer build — wipe-clean TPU top, printed film, ventilation channel, high-density EVA core, and an EVA grip base — cushions comfortably and protects your flooring underneath.
100% virgin USP Class VI–tested EVA — never recycled
Near-neutral surface pH 6.5–7.0, gentle on skin
Smooth, non-porous TPU surface wipes clean with mild soap and water
OEKO-TEX Standard 100 Class I on the whole product — the strictest tier, free of regulated harmful substances

Two Thicknesses
The Signature 0.5″ (12 mm) suits everyday setups and easy cleaning; the Boulder 1″ (25 mm) adds cushioning and sound absorption. Both use the identical virgin USP Class VI–tested EVA core and pH 6.5–7.0 chemistry. To price an exact configuration, build your floor here, or browse the everyday 0.5″ and 1″ ultra-thick ranges.
Certifications You Can Verify
Every PopsyKosy mat is tested against recognized safety standards: CPSIA compliance, ASTM F963 toy-safety protocols, EN 71 toy-safety certification, California Prop 65 screening, and USP Class VI biocompatibility. For impact cushioning, the mat is independently tested to EN 1177: the 1″ Boulder attenuates falls up to a 1.0 m critical fall height and the 0.5″ Signature up to 0.6 m. We publish what we measure — certificates and test reports are available in our product safety hub. We make no germ-killing, hygiene, or sanitizing claims; what the mat offers is verifiable materials and a non-porous, easy-to-clean surface.
Easy to Live With
Virgin EVA resists UV degradation and holds its shape across temperature swings, and the TPU surface resists scratching from everyday use — so the mat lasts longer and needs replacing less often, backed by our 2-year warranty. Cleaning is a simple wipe-down with mild soap and water.
