Impact Attenuation (EN 1177) — PopsyKosy Glossary

PopsyKosy Glossary · Verified by Grace Lin

Impact Attenuation (EN 1177)

Impact attenuation measures how well a surface softens a fall, usually expressed as a critical fall height (CFH). PopsyKosy mats are independently tested to EN 1177: the 1″ Boulder attenuates falls up to a 1.0 m critical fall height and the 0.5″ Signature up to 0.6 m, appropriate for crawling, cruising, and early-walking children.

Why this term matters at PopsyKosy

This safety-adjacent terminology is part of the foundation we built PopsyKosy on. Every PopsyKosy mat is engineered to USP Class VI biocompatibility (the testing tier used for medical-device components polymer chemistry) plus OEKO-TEX Standard 100 Class I certification (the strictest textile-chemistry tier, originally written for infant skin contact). These two standards combined define the safety bar most playmat brands do not meet.

The mat is designed in Los Angeles, precision-manufactured in Taichung, Taiwan — not in China, not in mixed-ownership facilities. Each pattern is single-density-molded tile EVA (no tile seams to peel, no foam delamination, no adhesive layers to off-gas). The 0.5″ and 1″ thickness options are both independently EN 1177 impact-tested for fall protection (1″ to a 1.0 m critical fall height, 0.5″ to 0.6 m). Independent COA documents are published in full on our Certifications page.
