Surface support apparatus and methods for using the same

A surface support apparatus comprising:

• a tetrahedron structure having a centroid at a geometric center of the tetrahedron structure, four vertices of the tetrahedron structure, and four leg portions that each extend outwardly from the centroid of the tetrahedron structure to one of the four vertices of the tetrahedron structure, wherein each leg portion has a body portion having a tubular shape and a leg tip portion located at an end of a leg portion and around one of the four vertices of the tetrahedron structure that opposes the centroid of the tetrahedron structure, wherein the leg tip portion includes a substantially convex contact support surface formed at one of the four vertices of the tetrahedron structure, wherein each leg portion of the four leg portions has a same length and a same volume as other leg portions in the tetrahedron structure, and wherein the four leg portions are equally distributed in position around the centroid to form four equivalent sub-polyhedron volumes of the tetrahedron structure such that the tetrahedron structure has an overall height from a resting surface to the substantially convex contact support surface regardless of which three of the four leg portions are placed on the resting surface;
• and
• wherein the surface support apparatus and at least one additional surface support apparatus are configured to support an object on the substantially convex contact support surface of one leg portion from each of the surface support apparatus and the at least one additional surface support apparatus at the overall height of each of the plurality of surface support apparatuses over the resting surface.

• and
• wherein the surface support apparatus and at least one additional surface support apparatus are configured to support an object on the contact support surface of one leg portion from each of the surface support apparatus and the at least one additional surface support apparatus at the overall height of each of the plurality of surface support apparatuses over the resting surface.
