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 a 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 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.
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 were usually joined together by being all attached to a same cloth or leather foundation, and were thus less influenced by the problems which plagued the cylinder desk.
