Tumble pioneered the rug-style aesthetic with cushion underneath. PopsyKosy's design language was developed by an LA designer in the Scandinavian-modern direction. On aesthetics, taste decides. On certification depth, PopsyKosy's OEKO-TEX Standard 100 Class I + USP Class VI is strictly stricter than the published Tumble stack.

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.
Tumble's design system is admirable — the rug-style aesthetic with cushion underneath solves the "I don't want a baby mat in my living room" problem. The hidden trade-off: the cushion is polyurethane foam (PU), not USP Class VI EVA. PU foam off-gases toluene and 2,4-TDI for the first 90 days of use, and the rubber-backing is not GREENGUARD Gold certified for the actual contact surface.
PopsyKosy chose a different aesthetic strategy: the large-format EVA tiles assemble into a low-profile rug look in Cream, Sage, or Glacier Grey, with cushion built into the EVA itself. No top cover, no underpad, no PU layer. The result is OEKO-TEX Standard 100 Class I (infant skin-contact) plus USP Class VI (medical-device biocompatibility) certifications that no Tumble assembly currently holds at the same depth.
Tumble mat
USP Class VI–tested EVA. CPSIA certified. Large interlocking tiles.
Designed in Los Angeles, precision-made in Taichung, Taiwan.
A tumble mat isn't just foam on your floor—it's the foundation of safe movement for your family. Whether you're coaching a toddler through their first forward roll or building a home gymnastics corner, the surface material determines everything from fall protection to indoor air quality. PopsyKosy delivers both without compromise, using USP Class VI-tested EVA refined to USP Class VI USP Class VI-tested material—the same rigorous standard governing medical-device materials and medical-device materials. This isn't industrial foam repurposed for children. It's a purpose-built tumbling surface that happens to be 100 to 1000 times cleaner than conventional EVA products.
The structural advantage starts with interlocking-tile construction. No seams means no dirt traps, no separation points, and no weak zones where tumbling impact concentrates. At 12 mm or 25 mm thick, our mats meet ASTM F1292 fall protection standards—validated cushioning that absorbs shock across the entire surface. Printed with zero-VOC soy-based inks, every colourway maintains its clarity without off-gassing volatile organic compounds into your practice space. This is particularly critical in gymnastics and tumbling environments where athletes spend hours in close floor contact during conditioning work.
Third-party validation matters when children are the end users. PopsyKosy mats carry CPSIA certification for eight heavy metals and eight phthalates, tested by accredited laboratories—not self-certified claims. Independent ISO 17025 labs confirm formaldehyde-free composition, while RIPT testing establishes hypoallergenic performance. These aren't marketing badges. They're documented safety thresholds that protect developing bodies during repetitive movement training.
Beyond gymnastics, these mats adapt to multiple household needs: tummy time for infants building neck strength, yoga and fitness routines, even pet-safe play zones. Seven designer colourways integrate into your home aesthetic rather than announcing themselves as gym equipment. Every order ships free across the United States with no minimum purchase requirement, backed by a 30-day satisfaction guarantee and two-year manufacturing warranty. If the mat doesn't perform as described, returns cost you nothing.
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.”
