Start with this (I copied off of the WEB):

FEDERAL style of furniture emerged after the American Revolution. In contrast to the Chippendale style, the federal pieces are more geometric, light and more delicate. Some of the features common to the federal style are fine inlay, cock beads, reeding, refined turnings, veneering and painting. The most popular piece in this style is the Windsor chair with spindle construction, spayed legs and carved slab seat.
