The ornamental design for a self-leveling bean bagcoaster, as shown and described.
FIG. 1 is a top, perspective view of the self-leveling bean bag coaster;
FIG. 2 is a top plan view thereof;
FIG. 3 is a right, elevational view thereof (the front, rear and left-side elevational views area mirror images and thus are omitted); and,
FIG. 4 is a bottom plan view thereof.
A self-leveling bean bag coaster includes a flexible “bean bag” base and a generally rigid planar top surface that allows a liquid filled vessel, e.g. a glass or can, or other item to be stably supported on a non-planar surface. It should be understood that the “bean bag” base can be filled with any suitable pellet-form stuffing.
