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.

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.

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.”

Non-Toxic Plyometric Box Mat: Medical-Grade EVA for Serious Athletes

Every impact matters. Whether you're training explosive leg power, conditioning for sports, or building functional strength, your foundation shapes everything. The PopsyKosy non-toxic plyometric box mat is engineered from 100% pure virgin USP Class VI–tested EVA—the only material that matches your skin's natural pH while delivering professional-grade impact absorption. This is the mat that 500,000+ mothers and serious athletes trust.

Why Medical-Grade EVA Changes Everything

Most plyometric mats use recycled polyethylene (PE), which carries unknown contaminants and registers at pH 9.5–10 on the alkaline scale. Your skin's protective acid mantle sits at pH 6.5–7.0. That mismatch matters, especially during high-intensity training when pores open and absorption increases.

Our signature non-toxic plyometric box mat uses only 100% virgin USP Class VI–tested EVA, measured and verified at pH 6.5–7.0. This single material choice eliminates the chemical disruption that cheap mats introduce. The result: a surface your body recognizes as safe, even during barefoot training or when you're building a home gym for your family.

The engineering runs deeper. Our five-layer construction starts with a TPU anti-scratch top coat, moves through an EVA print film and engineered air chamber, anchors to a high-density EVA core for impact distribution, and finishes with an EVA grip base. Every layer serves function. Nothing is filler.

Beyond safety, the material science delivers performance. Our mats achieve 99.99%+ antimicrobial coverage on the TPU surface—verified through ISO 21702 testing and registered with the USFDA (Reg #3010700940). This matters in shared training spaces, CrossFit boxes, and any environment where hygiene is non-negotiable.

Certifications That Mean Protection, Not Marketing

We list certifications because they represent real oversight, not because they sound impressive:

  • OEKO-TEX Class I: The world's highest standard for textiles and materials. We're the only EVA mat at this tier. This certification proves our material contains zero harmful substances—no heavy metals, no banned dyes, no carcinogens.
  • CPSIA + ASTM F963: Consumer Product Safety standards that matter most for items in active use.
  • ASTM F1292: Impact attenuation testing via 2-meter drop. Your mat absorbs force the way it promises.
  • California Prop 65: No listed chemicals. Transparency on what isn't present is as important as what is.
  • EN71 + USP Class VI: International toy safety and biocompatibility standards. These apply because families use our mats.

Manufactured in Taiwan under strict quality control, each mat ships with a 30-day satisfaction guarantee, 2-year structural warranty, and lifetime antimicrobial protection. These aren't promises—they're backed by 2,847 verified reviews averaging 4.95 stars.

Thickness That Matches Your Training

Impact absorption isn't one-size-fits-all. We offer two engineered options:

0.5" (12mm) Signature: Ideal for plyometric box training, jump rope stations, and mixed-use home gyms. Provides responsive feedback while protecting joints. Explore our everyday collection for this option.

1" (25mm) Boulder Ultra-Thick: Built for serious explosive training, high-impact conditioning, and extended barefoot use. Maximum energy return with superior shock distribution. Discover the ultra-thick collection for full details.

The choice depends on your training volume, body weight, and the intensity of your plyometric work. Both materials offer the same non-toxic construction and pH-matched safety.

Current Pricing — Signature 0.5"

  • Single mat: $109

Frequently Asked Questions

Is this mat safe for barefoot plyometric training?

Yes. The pH-matched USP Class VI–tested EVA, OEKO-TEX Class I certification, and USP Class VI biocompatibility clearance mean the material is designed for direct skin contact during intense exercise. The TPU anti-scratch top coat adds durability. More details are available on our product safety page.

How does USP Class VI–tested EVA differ from standard foam?

Medical-grade EVA is manufactured to pharmaceutical standards with rigorous purity controls and zero recycled content. Standard foam (especially recycled PE) may contain unknown contaminants, plasticizers, and
