Who makes an adjustable computer stand for couch? - recliner computer stand

I find that a manufacturer of a product that can make me end on a workstation for my home office offers.
Let me first say that I like to sit or lay on my couch and work.
So this season should be adjusted in height.
It must be large to a 20 "flat panel monitor, standard keyboard, mouse pads to keep. Also add an additional space for placing limits on certain foods, beverages and other documents and objects (such as CD, which I applications etc.).

The base can not slide on the couch and the chair on the street. I saw a house that "boom" of the system was too expensive. But I can not imagine that there is a manufacturer of high IT-as-you-need-offers IT system. I read of people in systems that Built (around your body like a machine centrifugal exercise device) and can no longer find.
