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.

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.”
Flexibility Mats for Grandparents: Engineered Support When Family Needs You Most
Grandparenting comes with joy—and physical demands. Whether you're playing on the floor with grandchildren, practicing gentle stretches, or creating a safe surface for family moments, the right mat makes all the difference. PopsyKosy mats are engineered for the flexibility and durability your active grandparenting life deserves.
Why Grandparents Choose USP Class VI–tested Mats
Your skin is sensitive. Your joints need support. Your family deserves safety. PopsyKosy mats are crafted from 100% pure virgin USP Class VI–tested EVA—never recycled—with a pH 6.5–7.0 that matches your skin's natural acid mantle. This matters. While standard mats measure pH 9.5–10 (alkaline), our precision-engineered formula reduces irritation and supports skin health during extended contact.
Our five-layer construction puts TPU anti-scratch protection at the surface, paired with a high-density EVA core that absorbs impact without compromising stability. You get the cushioning your knees need and the grip your feet rely on—whether you're kneeling to help with a grandchild's activity or practicing the flexibility routines that keep you mobile.
0.5" Signature Thickness: Ideal for daily flexibility work, gentle yoga, and floor play. Lightweight and portable for visits across homes.
1" Boulder Ultra-Thick: Maximum joint protection and comfort for longer sessions, therapeutic routines, or when you want the confidence of substantial support.
Hygiene matters when grandchildren are in your home. This engineered wipe-clean TPU surface stays active for the life of your mat—no treatments needed, no degradation over time.
We're the only EVA mat brand holding Class I OEKO-TEX status—a distinction earned through rigorous material purity and testing.
Our 4.95★ rating across 2,847 reviews reflects the trust families place in us.
Grandparents who stay flexible stay independent. Whether you're exploring gentle stretching, practicing balance work, or simply creating a comfortable surface for time on the floor with grandchildren, the mat beneath you affects your confidence and comfort.
PopsyKosy mats provide the stable, cushioned foundation that lets you focus on movement—not worry about surface integrity, skin irritation, or hygiene. The anti-scratch TPU top resists wear even with daily use. The high-density core maintains shape session after session. The grip base keeps you stable whether you're on hardwood, tile, or carpet.
Available in heritage-inspired colorways—from calming neutrals to warm earth tones—our mats blend into your home while performing with the reliability your body depends on. Discover options in desert sand, glacier grey, baby coral, and totem beige to complement your space and style.
Frequently Asked Questions
What's the difference between the 0.5" and 1" mats for flexibility work?
The 0.5" Signature thickness offers responsive cushioning ideal for daily stretching, yoga, and floor activities—it's portable and works well for varied routines. The 1" Boulder Ultra-Thick provides maximum joint protection and is favored by grandparents with sensitive knees, those recovering from injury, or anyone who spends extended time on the floor. Both deliver the same USP Class VI–tested EVA purity and wipe-clean cleanability; thickness is a comfort and support preference.

Unlike standard mats (pH 9.5–10), this reduces irritation during extended contact. We use 100% pure virgin USP Class VI–tested EVA with zero recycled content, and all materials are biocompatible (USP Class VI).
