The pattern relates closely to one published in Rudolph Ackermann's The Repository of Arts, 1811. It was noted as 'A new-invented sofa writing-table, represents one of the most simple and useful articles it is possible to have in the drawing-room, boudoir, or any apartment for the accommodation of ladies. It forms, in the first place, a handsome small card-table, and, with the help of two sloped neat pieces of mahogany or other wood, it becomes two writing or reading tables, having one drawer in each side, fitted up with pen, ink, and paper, so that two persons may at one time use it either as a writing or reading table, neither being able to overlook the other. By drawing out at each end the ornamented brackets, for the support of the two end flaps, it then forms as handsome a sofa table as can possibly be contrived either of mahogany, satin-wood, rose, king or any other fashionable Brazil wood'.
