A skateboard is adapted to include an auxiliary rotating platform which swivels upon a flat plate device secured to the upper surface of the board. An auxiliary platform is rotatably affixed to the top surface of the deck by a swivel mechanism that allows for full 360° rotation in both clockwise and counterclockwise directions. The auxiliary platform is preferably connected to upper deck surface by a flat bar stool type swivel mechanism having rotatably connected upper and lower plates separated by ball bearings. The auxiliary platform provides a structure capable of supporting the weight of the user while allowing the user to rotate about the swivel axis.
