I am going to post this on Clist for a friend but I have no idea how to describe it. Thanks!
I would call this a French-style BergÃ¨re corner chair.
Here is a link that might be useful:
I think French Rocaille might be a bit more descriptive, because of the foliate forms and assymetry
However it is Rocaille Revival if there is such a thing--it looks like 1960s---it could fall under the general umbrella of Hollywood Regency, which is a combination of a number of fancy historic styles.
versailles gone very, very wrong...
