Best Under-Desk Storage
What changes about storage when the desk moves, and the one cabinet worth buying for a sit-stand setup.
Top pick: Vari File Cabinet
A sit-stand desk travels roughly two feet, several times a day, and drags every cable and every attached object with it. That single constraint is what separates accessories that work on a sit-stand setup from accessories that work on a fixed desk, and it is why this category exists separately at all.
The obvious benefit is desk depth: a monitor stand occupies eight to ten inches, which on a 24-inch desk is a third of your working area. The two less obvious benefits matter more.
First, an arm decouples screen height from desk height. Your elbows set the desk; your eyes set the screen. On a factory stand those two are locked together, so a desk set correctly for your arms usually leaves the screen several inches too low and you spend the day looking down. Ergotron publishes about 13" of lift on the LX, which breaks that dependency entirely.
Second, an arm reduces the wobble you actually perceive. Monitors on tall stands sit high above the desk and act as a lever — mass far from the pivot turns a tiny deck movement into a visible screen sway. Clamping them to the desk edge lowers the center of mass and anchors it to the stiffest part of the top. The mechanism, and the two cases where an arm makes things worse.
Ergotron also publishes something almost nobody else does: with monitors over 20 lb, the LX Dual's vertical range may be reduced by up to 4.5", for a total height range of 8.5". A maker publishing a limitation of its own product is the single best reason to trust the rest of its figures.
The rule is one cable to the wall. Everything on the desk plugs into a power strip that is attached to the desk and travels with it, and that strip has exactly one lead going to the wall, with about two and a half feet of slack routed down a leg and a service loop at the bottom to absorb the travel.
Get that right and everything else is tidying. Get it wrong and the desk stops being raised — which is the real failure mode, because it costs you the entire purchase. The method, and the parts list.
Anything bolted under a moving desktop rises with it, so at standing height a drawer is at chest level and its contents are a surprise. Its weight also counts against the frame's rated capacity. The answer is storage that stands on the floor, rolls, locks, and is shorter than your desk's minimum height.
Vari's File Cabinet publishes three lockable soft-close drawers on roll-and-lock casters, a lower drawer taking letter- or legal-size hanging files, fully assembled delivery, and a cable opening for charging devices inside a drawer. That last detail is what separates it from a generic pedestal: the charging pile disappears rather than migrating to a corner of the desk.
One planning note. There is a finite amount of floor under a desk and several things here want it. A walking pad and a file cabinet will not both fit comfortably under a standard 60-inch top — decide which one you will actually use daily before buying the second.
