This is the neatest thing!  It folds flat and lives behind my entertainment center.  It did arrive with a bent bar but doesn’t seem to affect the stability of  the desk.  My only only negative is that it’s so tall and cannot be adjusted.  It’s out of  place so I can’t leave it set up or it throws off the balance of the room.   I do love it’s functionality though and it is exactly what I wanted and serves its purpose.
