High-strength, lightweight blow-molded plastic structures

A table comprising:

• a table top constructed from blow-molded plastic and including a generally hollow interior portion that is formed during the blow-molding process, the table top including an upper surface, a lower surface and a thickness measured from the upper surface to the lower surface;
• a plurality of depressions integrally formed in the lower surface of the table top as part of a unitary, one-piece structure, the plurality of depressions being arranged into a predetermined pattern that covers at least a majority of the lower surface of the table top, a majority of the plurality of depressions having a generally uniform configuration and a generally consistent distance between adjacent depressions, the plurality of depressions being sized and configured to increase the strength of the table top, the plurality of depressions including a height measured from the lower surface to an end of the depression, each adjacent depression of the plurality of depressions being separated by a distance that is generally equal to or less than three times the average height of the plurality of depressions;
• and
• a support structure that is connected to the table top to support the table top above a surface.
