Probably, the handiest and most useful accessory you can get for a computer desk or table would be the keyboard tray. Normally a desktop or table surface is simply too high for you to be able to reach and use a keyboard comfortably. With a keyboard tray you have the ability to orient the keyboard slightly lower than the desktop surface making it much easier to reach.

A keyboard tray is also, in affect, a storage device for the keyboard. When you aren’t using it simply slide it in and under the desktop. A keyboard tray is like a shelf on a sliding mechanism. A keyboard arm is very similar, but it has the added feature of tilt adjustment. This provides the maximum of comfort and positioning. Swivel your keyboard to get the perfect angle.
