A back, two sides continuously decreasing in height from the back toward the front, a bottom and a front, significantly lower than the back, are secured together to form a paper stacker. The bottom is doomed at is midpoint between the sides with the dome extending from the front to the back. A pair of quarter round moldings are disposed at the juncture of the sides and bottom and extend from the front to the back. Thus, there is formed a right parallelapiped with an essentially open front and slopping sides. The back can be extended by an extension attached to the stacker by teats which are attached to the sides of the extension and fit into slots extending through the back of the stacker at the junction with the sides allowing the back of the stacker and extension to form a coplanar surface when so attached. Multiple slots and teats are deployed at essentially equal intervals.
