The cool design product Underbed Lift™ from MK I Studio is the original.

They said, ‘We invented the concept and have been refining it for almost a decade.  A 50″ panel with Amplifiers, DVD, VCR, Subwoofer, and 7 channels of surround can be concealed beneath a King size bed  and a 42″ panel and all the same equipment can be concealed under a Queen size bed.  Both only take 35 seconds to deploy.  

The Underbed Lift™ gives you the freedom to decorate any way you desire without having an entertainment center or cabinet as the main focal point. It also won’t take up your floor space or block the view out  of windows and doors.’

Really is a cool design solution to watch TV in bed, nice try.
