This chair is of high quality, although not a reproduction of a specific piece. It has a well done diamond-shaped splat based on New York designs of the 1750-1780 period.
The knees of the front legs are nicely carved and it has well articulated claw and ball feet.
The mahogany has great color and the piece has been waxed and includes a new Brunschwig & Fils silk damask seat cover. This piece would be great used as a desk chair, in an entry hall or as a extra chair in a living room or library.
For more information about period American Chippendale chairs I suggest Albert Sack's "Fine Points of Furniture, Early American," colloquially known as "Good, Better, Best." For more reading on Colonial Revival furniture I would refer to "Colonial Revival Furniture" by David P. Lindquist and Caroline C. Warren.
