Twelve trays turn a desk corner into a filing system: one for envelopes, one for receipts and statements, one for pens and markers, one for sticky notes, one for cords, and more still free. Each tray measures 13 in by 10 in with 2.5 in of clearance, which lays letter sheets and folders flat and keeps a stack of small items visible instead of stacked. Trays glide on metal channels and lift out for sorting at the desk. The 25-in by 15-in top adds a landing spot for a printer or an inbox, and the 18.5-lb frame rolls on four casters with two locks.
