[kwlug-disc] Couch laptop table/platform?

[unsolicited]

Being the unreformed couch potato that I am, with a small laptop, 
already with a sore neck from tilting my head down to read it, and now 
needing reading glasses to see the screen ... anyone know of laptop 
table thingies and where to get them for couch laptop use?

Wheels would be required, and the table must extend over the cushions. 
Even better, given the laz-y-boy, if things fit over the footrests!

I could see an end table with an arm that swings over, or a cart I 
could push away when I get up. More likely the latter, there's already 
enough junk on the end table.

Decadent, I know, but we live in that kind of society.

I'm thinking Staples. Neither stack a shelf nor costco web sites seem 
to have anything suitable.

Suggestions?
