If you're looking for a desk that moves with you, this Mount-It! mobile standing desk is seriously awesome. The top two platforms are extra wide at 39.5 inches - plenty of space for dual monitors, your keyboard, mouse, and other office gear. What's really cool is you can adjust the height from 37.25 inches up to 55 inches with just a turn of the locking knobs, no tools needed! That's 17.75 inches of adjustment range so you can switch between sitting and standing throughout the day. There are four shelves total - the middle one's great for books and papers, while the bottom shelf can handle your computer tower or printer. The whole thing holds up to 132 pounds (33 lbs per shelf) and rolls smoothly on casters that lock in place when you need stability. Made from steel, plastic, particle board and melamine, it's sturdy enough for office use, trade shows, schools, hospitals, or even at home. Seriously, whether you're doing presentations or just want a workstation you can move around, this thing has you covered.
