3M Premium Adjustable Monitor Stand
These are terrific & come in 2 widths, 20" & 15". I have 3 of the wider ones under my desktop laptop, a monitor & a TV; 2 of the narrower ones, under a scanner & label printers. They free up invaluable desktop space underneath, giving room under the TV for the cable box, under the monitor & laptop for paperwork, under the scanner for documents being scanned and under the label printers for a cassette transcription machine. They're height-adjustable, so you can make them as short or tall as you need, which is a real bonus; also very durable, and blend in nicely with other office equipment. With them, my home office is much more efficient!
