  • Patent number: 4389435
    Abstract: A playing surface for athletic games comprising a stable subsurface, a resilient underpad of specified character, a pile fabric resembling grass and a sand top dressing. The inventive surface is particularly suited for use as a golf green which properly facilitates control of an approach shot and also provides a true putting surface. The playing surface simulates the feel and appearance of natural turf, but has much greater durability and requires less maintenance. By appropriately varying the construction of the surface, it is possible to control its character to provide for a desired type of play.
