A stackable office tray for the temporary storage of documents comprising a substantially rectangular base with two longer sides and two shorter sides; two side walls extending upwardly from said longer sides of said base; a rear wall extending upwardly from one of said shorter sides; a front access opening on the other of said shorter sides; and two runners on the under side of said base adjacent and parallel to said longer sides of said base, said tray being stackable in a vertical stack with a similar tray thereunder and said runners having side faces extending in longitudinal direction and adapted to engage faces of the side wall of the similar tray thereunder for holding the two trays in the vertical stack against displacement in longitudinal direction and in a direction transverse thereto, said tray being also stackable in a stair-like stack with a similar tray thereunder and said runners having further at least one pair of first recesses adapted to be engaged with the rear wall of a similar tray thereunder while said side faces of said runners engage faces of the side wall of the similar tray for holding the two trays in the stair-like stack against displacement in longitudinal direction and in direction transverse thereto, said tray being further stackable in a crosswise stack with a similar tray thereunder and each of said two runners having further a pair of second recesses respectively adapted to be engaged with said two side walls of a similar tray thereunder for holding the two trays in the cross-wise stack, at least two of said four second recesses being arranged for holding the upper tray against displacement in longitudinal direction of said runners with regard to the lower tray and in a position in which the portion of the upper tray provided with said front access opening extends outwardly beyond the adjacent side wall of the lower tray a distance considerable greater than the rear wall of said upper tray extends outwardly beyond the adjacent side wall of said lower tray.
