Ergo Works offers a wide selection of ergonomic keyboard tray systems that are designed to make your workstation more comfortable. The primary benefit of a keyboard tray systems is that it allows you to adjust the height of your keying and mousing surface and is a perfect solution for a multi-user workstation. You will need to consider the worksurface depth, width of the desk opening, and your keyboard and input device when making your selection. If possible we recommend a keyboard tray platform that is wide enough to accommodate both your keyboard and input device (mouse or trackball) to eliminate excessive reaching. Also remember that installing a keyboard tray will lessen the amount of available leg room under the worksurface, so be sure there is enough room after the keyboard tray is installed.
