Not all foam is created equal. EVA foam — the material in most puzzle-piece play mats — compresses under impact and bounces back. Memory foam does something different: it absorbs impact progressively, cradling your baby rather than bouncing them.
PocoKoko mats use 1.3 inches of CertiPUR-US certified viscoelastic memory foam. That's the same slow-rebound technology used in premium mattresses and hospital pressure-relief surfaces — but engineered specifically for the crawling-to-walking stage, when falls happen dozens of times a day.
Our foam is independently tested for formaldehyde, heavy metals, phthalates, PBDE flame retardants, and VOC emissions. Every batch. Every time. You can verify our certification on the CertiPUR-US website.
The one-piece construction means there are no puzzle pieces to pull apart, no gaps to trap moisture or crumbs, and no small parts that could become choking hazards. Just one seamless surface that's easy to wipe clean.
Frequently Asked Questions
How is memory foam different from EVA foam?
EVA compresses and bounces. Memory foam absorbs and cradles. For a baby falling from standing height, memory foam provides significantly better impact absorption. Read our full comparison →
What is CertiPUR-US certification?
CertiPUR-US is an independent testing program for foam products. It verifies that foam is made without harmful chemicals and meets strict emission standards. Learn more about CertiPUR-US →
How thick is the memory foam?
1.3 inches (33mm) — approximately 3x thicker than standard play mats. The foam fully expands within 24-48 hours after unboxing.
Will the memory foam flatten over time?
Quality memory foam maintains its shape for years. Our foam density is engineered for daily use by children — it won't bottom out or permanently compress under normal use.
