What is a Bergere?
Allow us to cheat a little on historical data, and refer to the Wikipedia entry on the style:
A bergère is an enclosed upholstered French armchair (fauteuil) with an upholstered back and armrests on upholstered frames. The seat frame is over-upholstered, but the rest of the wooden framing is exposed: it may bemoulded or carved, and of beech, painted or gilded, or of fruitwood, walnut or mahogany with a waxed finish. Padded elbowrests may stand upon the armrests. A bergère is fitted with a loose, but tailored, seat cushion.
It is designed for lounging in comfort…A bergère in the eighteenth century was essentially a meuble courant, designed to be moved about to suit convenience, rather than being ranged permanently formally along the walls as part of the decor.
