Rolltop desk
A rolltop desk is a 19th-century reworking of the pedestal desk with, in addition, a series of stacked compartments, shelves, drawers and nooks in front of the user, much like the bureau à gradin or the Carlton House desk. In contrast to these, the compartments and the desktop surface of a rolltop desk can be covered by means of a "tambour" consisting of linked wooden slats that roll or slide through slots in the raised sides of the desk. In that, it is a descendant in function, and partly in form, of the cylinder desk of the  18th century. It is a relative of the tambour desk, whose slats retract horizontally rather than vertically. The rolltop desk was re-invented by Jacob Alles in Jasper, Indiana in 1879. "About 1760 Jean-François Oeben designed a new type of bureau: the original rolltop desk. The writing area can be covered by a shutter made of flexible slats, which is rolled round a cylinder hidden behind the top tier of drawers. In the Château de Versailles is found the most famous example of this type of desk, the "bureau du roi," which was begun by Oeben in 1760 and  finished by Riesener. Riesener made several rolltop desks; the one for Thierrry de Ville d'Avray indicates that the Louis XV style was not yet regarded as outmoded in the 1780s". Production. Unlike the cylinder desk, the rolltop desk could be mass-produced rather easily since the simple wooden slats could be turned out very fast in a uniform way. In contrast, the wooden section of a cylinder had to be treated with great pains to keep its form perfectly over time, lest it warp or bend, and make it impossible to retract or extend. The wooden slats of the rolltop 's tambour were usually joined together by being all attached to a cloth or leather foundation, and were thus less influenced by the problems which plagued the cylinder desk. Usage. The rolltop desk was the mainstay of the small or medium-sized office at the end of the 19th century and the beginning of the 20th. Because it was produced in vast numbers and at varying levels of quality, the rolltop desk is popular in the antique market. It is usually expensive especially if the wood used is expensive. It is also popular amongst set decorators who want to recreate  the ambience of an office of the late 19th or early 20th century.
