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.”

USP Class VI–tested EVA Mats for Your Sunroom Rebounder Trampoline

Engineered with 100% pure virgin USP Class VI–tested EVA—the only trampoline mat that matches your skin's natural pH balance while delivering wipe-clean cleanability your family deserves.

Why Sunroom Rebounders Deserve Premium Matting

A sunroom rebounder transforms movement into a wellness ritual. Low-impact bouncing strengthens your lymphatic system, improves balance, and renews energy—but only when your mat foundation meets clinical standards. Most trampoline mats use recycled polyethylene (PE), which carries an alkaline pH of 9.5–10. This creates micro-friction against skin, disrupts the acid mantle that protects you, and offers zero assurance.

PopsyKosy mats are engineered differently. Beneath sits our EVA print film, an air suspension layer, a high-density EVA core, and a grip base—all virgin USP Class VI–tested EVA at pH 6.5–7.0, matching your baby's skin.

This is the heritage choice for families who understand that wellness begins with materials integrity.

Clinical Certifications That Matter

PopsyKosy holds every certification that protects your household:

  • OEKO-TEX Standard 100 Class I — the EVA mat at this tier, tested for harmful substances across 100+ parameters
  • CPSIA — Consumer Product Safety Improvement Act compliance
  • ASTM F963 — toy safety standard
  • — drop impact safety from 2 meters
  • Prop 65 — California's strictest chemical safety protocol
  • EN71 — European toy safety directive
  • USP Class VI — biocompatibility for medical applications

Made in Taiwan with precision engineering, our mats have earned 4.95 stars from over 2,847 verified reviews across 500,000+ families. This is the data of trust.

Frequently Asked Questions

How does pH 6.5–7.0 EVA protect my skin during rebounder use?

Your skin's acid mantle—its natural pH of 4.5–5.5—is your first immune barrier. When you bounce barefoot on alkaline PE mats (pH 9.5–10), micro-abrasion occurs, weakening this barrier and increasing sensitivity to irritants. PopsyKosy's pH 6.5–7.0 EVA maintains this balance, reducing friction and supporting your skin's natural defense system. This matters especially for children and those with sensitive skin. Learn more about our safety protocols.

For sunroom rebounders shared across family members, this reduces pathogen transmission during high-contact activities. It's not a substitute for hygiene, but a material-level safeguard that works continuously.

Why is virgin EVA different from recycled PE in a mat?

Virgin EVA is manufactured fresh from ethylene and vinyl acetate polymers, allowing precise control of density, pH, and purity. Recycled PE is ground-down plastic from previous products—its composition is variable, its chemical additives unknown, and its pH consistently alkaline
