Uncaged Ergonomics WorkEZ Adjustable Monitor Stand Riser for Desk, Black | Aluminium computer riser, 16 x 11 in panel that rotates 360, holds up to 13 lb, folds flat at 3.1 lb.

RAISE IT 2 TO 18
INCHES: The legs open across a 16 inch range, so this height adjustable monitor stand brings the screen to your eye line instead of you dropping your chin toward the desk all day.
TURN THE SCREEN,
NOT THE DESK: The panel turns a full circle and locks every 15 degrees, so this monitor swivel stand angles a display toward someone beside you and clicks straight back to your position.
TAKES UP TO 13 POUNDS: Aluminium construction carries a full-size screen without flex or wobble, so an adjustable computer monitor stand this light still holds a heavy display steady.
GOES TALL ENOUGH TO STAND: At the top of its range this tall monitor stand puts a screen at standing height on an ordinary desk, so you can work on your feet for an hour without buying a converter.
16 BY 11 INCH TOP PANEL: This aluminum monitor stand supports the whole base of a large screen rather than one edge of it, and two stands sit side by side if you run more than one display.
FOLDS FLAT,
NO TOOLS: At 3.1 lb the whole thing collapses and lifts with one hand, so this portable monitor stand moves between desks or into a bag with no installation at either end.
