Besource 3-Tier Mesh Desktop File Organizer - Stackable Letter Paper Tray with Compartments for Office, Home & School - Black (Perfect for Organizing Documents, Mail, and Office Supplies)

Nice and sturdy, had to take a good 5-10 minutes to assemble and screw all the pieces together. It does not come with a tool to help. I had to pull out my Phillips screwdriver to assemble. You have to line up the holes on the trays very well or it throws the whole sturdiness off. There are about 12 screws on this thing. Once assembled, it does it job and looks nice.
