Abstract: A submergible stool includes a body having a top, a bottom spaced from the top, and a sidewall extending between the top and the bottom and defining an enclosed interior cavity extending between the top, the bottom, and the sidewall. A first aperture is formed in the sidewall proximate the bottom and extends from the enclosed interior cavity to an exterior of the stool. A second aperture is formed in the sidewall proximate the top and extends from the enclosed interior cavity to an exterior of the stool. The apertures are positioned such that when the stool is placed in a body of water, water will flow into the interior cavity through the first aperture, air will be forced out of the second aperture, and the stool will sink to a bottom of the body of water in an upright position.

Abstract: A submergible umbrella stand includes a body including a top, a bottom spaced from the top, and a body wall extending between the top and the bottom and defining a body cavity therein. At least one filling aperture is formed in the top. An umbrella sleeve is positioned within the body and is configured to receive an umbrella pole. An upper recess is formed in the top and includes an upper recess sidewall extending inwardly and downwardly from the top of the body into the body cavity and a bottom extending inwardly from a bottom of the upper recess sidewall. A first sleeve aperture is formed in the bottom of the upper recess, with the umbrella sleeve extending through the first sleeve aperture.
