Computer table
A computer table generally has wheels and is specifically used for a computer and its peripherals (keyboard, mouse, monitor, multifunctional printer, trackball, speakers ).
Gyratory computer tables can be used over a bed by people that are bed-ridden (i.e. because a spine problem they have to be horizontal). In this case is convenient to use trackball (instead of mouse) and a keyboard extension cable in a ergonomic keyboard tray. This is often used with a WiFi LCD monitor, which is much smaller, lighter and sold than a CRT monitor and can be used wirelessly.
Some computer tables for bed-ridden people are modular, so they can separate one fix module (with the WiFi computer case and connection to the Internet) and two portable modules (one with with WiFi LCD, trackball, mouse and other for, eventually, the multifunctional).
