Super Deal Angle and Height Adjustable Rolling Table Desk
It doesn't get more adjustable than the Super Deal Angle and Height Adjustable Rolling Table Desk ($46, originally $50). No need to worry about your items sliding or falling because this 360-degree swivel tray is equipped with safety edge bumpers and lockable wheels. You can tilt the tray up 180 degrees and adjust the desk up to 35.5 inches off the ground (be sure to measure the height of your bed, especially if you have a box spring if you're considering using this one).
