Abstract: A desk assembly is disclosed utilizing a framework for supporting side and back panels and file drawer slide assemblies. Adjacent frameworks may be clipped together to form a credenza; they may be spaced apart and joined together by a desk top slab; an extension may be added to form an L-shaped desk unit. An accessory-holding track assembly is included formed from an extruded track with exposed and internal channels. Accessories are positioned in the exposed channel; support members are positioned in the non-exposed channels. Identical slide drawers are utilized, with boxes therein of differing heights. Drawer fronts of differing heights corresponding to the different heights of the boxes are utilized. The entire framework is filled with file drawer boxes of differing heights, and the module is fronted by corresponding drawer fronts of differing heights. A file drawer compressor or follower is used, resiliently biased against the sides of a file drawer.
