A rolltop desk is basically 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 Carleton house table. Unlike these two however access to the compartments as well as the desktop, can be covered by the means of wooden slats rolled, or slid on slots in the sides. In that, it is a descendant in function, and partly in form, of the cylinder desk of the 18th century, and it is a relative of the tambour desk whose slats retract left and right to the sides instead of up and down to the back.
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.
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. It gradually fell out of favor with the introduction of the steel desk and the coming of greater quantities of correspondence and other documents, which made the stacked drawers and small shelves obsolete. There were just too many letters to bother folding them again and placing them in the proper slot and there was too little time to open and close all the small drawers to look for things.
Because it was produced in vast numbers and at varying levels of quality, the rolltop desk is popular in the antique market. It is also popular amongst set decorators who want to recreate the "ambiance" of an office at the turn of the previous two centuries, or during famous eras like prohibition. The rolltop has starred in many plays and movies, the most famous one being probably a movie called His Girl Friday with Cary Grant and Rosalind Russell.
