You can purchase keyboard trays from the systems furniture manufacturer, or from other sources such as Boise Cascade. Keyboards vary in styles and options, but they all are attached to the underside of the worksurface. Systems furniture offers storage above, below or next to the worksurface. Open shelving and overhead bins offer convenient storage that is easily accessible without taking up valuable floor space. They can be mounted on the panel at varying heights.
Pedestals consist of regular and file drawer units that are under the worksurface.
When adding storage under a worksurface, keep in mind that there should be enough leg space so as not to constrict movement. Lateral files are another option for storage under a worksurface. They can be either panel hung or freestanding. The panel-mounted units must be the same width as the panel, and the panel can support up to four drawers. The freestanding lateral files are available in a variety of widths and heights.
