Abstract: A multi-layered surface suitable for a playground, including a top layer of perforated resilient mats is also provided with a bottom shock-absorbing layer having pockets or perforations capable of supporting the growth of grass or other plant material from under the mats. A middle mesh layer helps distributes forces sideways. This invention overcomes the inherent absence of resilience in grassed playgrounds and is compatible with formal tests for impact resistance. The resulting playground environment is more natural in appearance than that of an undressed plastics mat surface.
