Placing the work surface right next to the user seated in the front of the vehicle. The tray comes with a non-slip pad, providing extra security so the laptop or tablet with keyboard won't move around while working. There is an additional security strap for a laptop or a tablet with a built-in keyboard. Keep all of your valuables safe with the hidden storage space located beneath the desk work surface.
