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.
Playmat for twin babies
USP Class VI–tested EVA. CPSIA certified. Large interlocking tiles.
Designed in Los Angeles, precision-made in Taichung, Taiwan.
A playmat for twin babies needs to do more than look good—it has to deliver twice the durability, twice the safety, and enough space for two little explorers to move freely without compromising on hygiene or structural integrity. PopsyKosy's interlocking-tile design eliminates seams where dirt, moisture, and bacteria typically accumulate, giving parents of multiples a surface that stays genuinely clean between wipe-downs. With fifteen millimeters of ASTM F1292-certified fall protection, the mat cushions tumbles during those wobbly first crawls and early cruising stages—critical when you're monitoring two babies learning to move at different paces.
What sets this mat apart for twin households is the material standard. PopsyKosy uses USP Class VI-tested EVA refined to USP Class VI USP Class VI-tested material—the same benchmark required for medical-device materials and medical-device materials. That means it's one hundred to one thousand times cleaner than the industrial-grade foam found in typical play mats. For families with two infants spending hours on the floor daily, that difference matters. The mat is CPSIA-certified for eight heavy metals and eight phthalates through accredited laboratory testing, and independently verified formaldehyde-free by an ISO 17025 lab. It's also RIPT-tested hypoallergenic, so sensitive skin—common in newborns and especially twins with genetic predispositions—stays protected.
Printed with zero-VOC soy-based inks across seven designer colorways, the mat integrates into your living space rather than dominating it. Whether you're setting up separate tummy time zones or creating one large safe area where both babies can roll and reach, the surface performs equally well for early motor development and later fitness use as your twins grow. PopsyKosy backs every mat with a thirty-day satisfaction guarantee, free returns, a two-year manufacturing warranty, and free shipping on every US order with no minimum purchase required.
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.”
