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 Basement Gymnastic Mat Engineered for Growing Bodies
USP Class VI-tested safety meets performance. Discover why 500,000 families trust PopsyKosy mats for home gymnastics training, from preschool tumbling to serious athletes.
Why USP Class VI-tested EVA Changes Everything
Most gymnastics mats begin as recycled plastic. Ours begin as 100% pure virgin USP Class VI–tested EVA—the same material trusted in surgical applications and infant care. This distinction matters when your child spends hours training on the surface.
Our pH 6.5–7.0 formulation matches the natural acid mantle of baby skin, preventing the alkaline irritation (pH 9.5–10) found in standard PE mats. The result: a mat that supports skin health alongside athletic development.
This matters in basement environments where humidity and enclosed spaces create conditions for microbial growth. Our safety certifications
Engineered Architecture: Five Layers, One Purpose
Basement gymnastics demands a mat that absorbs impact without breaking down. Our signature construction stacks performance from top to bottom:
TPU Anti-Scratch Surface: Resists wear from repeated tumbling and equipment contact while maintaining the wipe-clean cleanability.
EVA Print Film: Locked-in color and pattern that won't fade, peel, or transfer onto skin and clothing.
Engineered Air Layer: Precision-calibrated for shock absorption without compromising stability during handstands and balance work.
High-Density EVA Core: The structural heart—dense enough to support advanced skills, responsive enough for younger learners.
EVA Grip Base: Stays anchored to concrete or vinyl basement flooring without requiring adhesives or tape.
This is the only EVA mat lineup earning OEKO-TEX Standard 100 Class I certification—the world's strictest standard for textiles touching skin. We're the only EVA mat manufacturer at this tier.
Basement Training Reimagined
Home gymnastics training has evolved. Parents no longer accept mats that crack, yellow, or emit chemical odors in enclosed spaces. PopsyKosy mats were engineered specifically for basements: thicker cushioning, superior moisture resistance, and performance that persists for the life of the mat—not just the first month.
Choose your thickness based on skill level and space:
0.5" (12mm) Signature: Ideal for beginners and preschool tumbling. Portable enough to roll and store. Discover our Signature collection.
1" (25mm) Boulder Ultra-Thick: Engineered for advanced skills—aerials, back handsprings, complex combinations. Explore the Ultra-Thick lineup.
Will a USP Class VI–tested EVA mat perform differently than standard foam?
Yes. USP Class VI-tested EVA offers superior resilience and durability. It won't compress, yellow, or develop odor the way standard closed-cell foam degrades over 12–24 months. The high-density core maintains its shock-absorption properties through thousands of training sessions. Additionally, the pH-neutral (6.5–7.0) formulation prevents skin irritation during extended contact—critical for young gymnasts training multiple hours weekly.
Is wipe-clean cleanability necessary indoors, or is this marketing?
Basements create ideal conditions for mold and microbial growth: lower light, higher humidity, and temperature fluctuations. The TPU surface prevents biofilm formation that other mats experience within months. This extends mat lifespan and maintains a healthier training environment—particularly important for children with sensitive skin or respiratory considerations.
What happens after purchase if the mat doesn't meet expectations?
Every PopsyKosy mat includes a 30-day full-satisfaction guarantee—explore our mat at home, train on it, and return it if it doesn't align with your needs. Our 2,847 verified reviews (4.95★ average) reflect why 500,000+ families choose us as the heritage choice in home gymnastics equipment.
