I'll build a cradle out of wood and carpet it for safety. Scoot the desk right under the tv and raise it up so the wood assembly grabs the bottom and hoists it up, then lean it over onto a slanted wood carpeted back that I'll make..
I'm a little surprised there's not a better option.
My second option is the Air Bag TV Drop mentioned above. That serves this purpose and is also fun for the whole family.
