"favourite piece of furniture: a Louis XIV escritoire"

Worth a fine fortune today, the royal French furniture style of King Louis XIV wears smooth curves and a beautifully rounded off style. Such baroque antiques flourished in 18th century France and dripped decadence.

The escritoire or writing desk referred to by LMS would probably have had a sloping front, which would have opened down for use as a writing surface and held drawers for writing materials inside.
