Around 1700, André-Charles Boulle develops new models of furniture for small items: jewelry, medals, collections, bathroom accessories. The cabinet with drawers becomes the precursor of the commode designed by himself circa 1706.
The cassette or coffre de toilette is a small coffer mounted on a base of same area. Sixty years later, when the storage box becomes narrower than the tablet, this model of furniture will become the bonheur-du-jour.
These innovations also precede the flat desk, which should be mentioned here as a reminder that Boulle was the designer of all modern forms of French furniture. The luxury of his inlays in première partie and contrepartie and of his gilded bronzes is also unprecedented.
From 1700 until the fire of 1720 and perhaps a little beyond, the cassette sur piétement was one of Boulle's regular product lines. The coffer and its ornamentation were prepared independently and assembled when the workshop received an order.
A pair of cassettes sur piétement was sold for £ 1.55M including premium at Christie's on December 8, 1994.
Another pair also attributed to Boulle is estimated € 1.5M, for sale by Christie's in Paris on November 5, lot 53. The base with four covered feet is topped with a drawer and equipped with a spacer plate centered by a bronze vase.
