Miniature, roll-up halfpipe (10) for use with fingerboards (60) or miniature skateboards includes a pair of sideframes (11, 12) configurable in either a collapsed, compact configuration or an extended, open configuration. Platfor ms (50, 52) join the end portions of the sideframes to form a generally rectangular structure having a pair of upwardly open curved edges. Flexible, resilient sheet (35) is received upon the supporting frame to form a curved surface of the type frequently used by skateboarders. In the closed configuration, the flexible sheet is rolled into a cylindrical shape and encloses the collapsed sideframes (11, 12) and platforms (50, 52). A pair of generally cylindrical endcaps (61, 62) are received upon the opposed ends of the rolled sheet (35) to provide closure and secure attachment.
