I believe it's a late 19th century....late Victorian chair that is part of a parlor set....which would have included a settee, perhaps a "patent rocker" a ladies chair and a gentleman's chair...as well as a side chair and a corner chair.
Chairs that fit into a corner were very often part of such a set....and this chair would have likely have been used in a corner.
The wood appears to be maple...not chip carved as is typical of Eastlake, but "engraved" as in earlier styles.
