Abstract: The present invention is a mouse pad for use with a computer mouse or tracking device. The mouse pad includes a planar plate including a top surface, adapted for use as a computer mousing surface. It also includes a flexible outer membrane including a bottom; wherein the planar plate is fastened to the flexible outer membrane, such that said outer membrane and planar plate define a cavity. It further includes fluid like fill media received within the cavity for supporting the planar plate such that the membrane bottom is adapted to substantially conform to the contour of an uneven surface it is placed upon, thereby providing a stable base and a usable mousing top surface when placed on uneven surfaces.
