This is a pretty elaborate corner workstation from IKEA. It is very space efficient.
Comes with side rack for folders/magazines, a small magnet board, and shelf space on top.
Dimensions:

Desk w/out shelf part: H 29 1/2'', short side: 23 2/3 '', long side: 47 1/4''
with shelf part: H 64 1/2''

It fits at least a 20'' screen (that's what I used it for), perhaps a bit more.

Can be disassembled for transport. Some wear and tear, but looks fine and functions well. In Palo Alto. Must be picked up by Friday 8/13/10.
