Apron

A structural support placed at right angles to the underside of a shelf, chair seat, or table top to provide additional weight bearing strength and often decorative flourishes.

Pedestal

A tall, narrow base which supports a statue, lamp, vase or any decorative object. Usually treated with moldings at the top and a base block on the bottom. Without moldings it is called a plinth.

Filigree

Primarily refers to fine, ornate metalwork (mainly in gold, silver, or copper), that is intricately patterned and used as ornamentation or embellishment, particularly in fine jewelry making. More broadly, the term can refer to any ornamental openwork that is delicate or fine that resembles a metal filigree in its pattern, but in other mediums.
