Love this folding desk. It's compact but not cramped, and it folds in seconds. It's nice and stable, not wobbly at all. Works well with a folding chair. There's enough room on the top level for a flat screen monitor, but I'm just propping my laptop up there. 

I'm very petite (5'1") and it's a nice size for me. Not sure how well it would work for someone who is really tall.
