What is the difference between soft play and a playground?
Soft play is padded indoor apparatus intended for younger children, typically two to eight years, in a contained commercial setting. The safety requirements come from a different standard in the US — ASTM F1918 for soft contained play structures rather than ASTM F1487 for outdoor playgrounds — because the padded environment changes the fall height assumptions. In Europe, EN 1176-1 is generally applied with modified assumptions.
