A synthetic-grass flooring may include a substrate with multiple filiform formations extending upwards from the substrate to simulate natural-grass cover or turf. End portions of the filiform formations may be curled to bestow upon the filiform formations a general tree-like conformation. The synthetic-grass flooring may be manufactured as a finished product in a factory. A particulate filling material or infill may be retained on the substrate by the curly ends of the filiform formations.
