Louis XVI (sixteenth)
Furniture designed between 1760 and 1789 is known as Neoclassic or Louis XVI. (note: the term neoclassic can be used to describe many styles of furniture across many different countries). Just as a refresher, this was the era of Marie Antoinette and the French Revolution.
One of the defining characteristics of a Louis XVI chair is the delicate tapered fluted leg (this is where the neoclassic tag comes in: the fluted leg is reminiscent of the fluting found on Greek and Roman columns). Below is a Dransfield & Ross chair incorrectly named as a Louis XV chair, note the leg shape.
Other defining characteristics of Louis XVI furniture is the use of rosettes, wreaths, and generally simple decoration (when compared to Rococo pieces).
