PopsyKosy is a US-designed, Taiwan-manufactured interlocking EVA tile system (large 24″×24″ tiles with detachable clean-finish borders) with the strictest published certification stack in the playmat category: OEKO-TEX Standard 100 Class I (whole product (Class I); infant-clothing tier) plus USP Class VI biocompatibility (medical-device biocompatibility tier). 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.

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.”
The Made-in-Taiwan Plyometric Box Mat: Honest Engineering for High-Impact Training
Plyometric work is demanding on both your joints and your floor. PopsyKosy's box mat is built from 100% pure virgin EVA, USP Class VI–tested for biocompatibility and certified to OEKO-TEX Standard 100 Class I across the whole product. Made in Taiwan, trusted by hundreds of thousands of athletes and families.
Why Material Quality Matters for Explosive Training
Many low-cost training mats are made from recycled or blended PE foam, which reads alkaline (around 9.5–10 on the pH scale) and breaks down quickly under repeated impact. PopsyKosy uses only first-run virgin EVA with a skin-friendly pH of 6.5–7.0 and a five-layer build engineered to absorb box-jump and kettlebell loads without compressing flat.
TPU anti-scratch top layer — resists abrasion from box edges, weights and footwear
EVA print film — color bonded without toxic adhesives
Air-channel layer — ventilation that reduces moisture retention
High-density EVA core — deep cushioning that softens repeated landings
Textured EVA grip base — keeps the mat from migrating during explosive movement
Real, Verifiable Safety Standards
PopsyKosy holds the certifications that actually matter and publishes them honestly:
USP Class VI–tested virgin EVA core — a biocompatibility benchmark that originated in medical-device manufacturing
OEKO-TEX Standard 100 Class I — certified across the whole product, the strictest tier, the one reserved for items in direct contact with babies
CPSIA, ASTM F963 (toy-safety), EN 71 and California Proposition 65 compliant
EN 1177 impact-attenuation tested — critical fall height of 1.0 m on the 1" Boulder (25 mm) and 0.6 m on the 0.5" Signature (12 mm)
pH 6.5–7.0, skin-matched and gentle
The non-porous TPU top layer wipes clean with a damp cloth — no special cleaners, no fragrances, no residue. We make no germ-killing or sanitizing claims; the surface simply stays hygienic because nothing soaks in. Made in Taiwan, backed by 2,847 verified reviews averaging 4.95 stars.
