Manufacturers and suppliers of natural wood play surface material all call it by different names, but basically it's all the same stuff, natural wood bark or natural wood chippings.
Play bark is usually more expensive than wood chippings but all serve the same purpose, as safe surfaces in children's play grounds. Make sure the bark or chippings is tested to BS EN 1177: 1998 safety standards
