Lorell 99552 Electric Desk Riser Black 17.1x28.8x35.8 in office furniture

Electric desk riser with USB

The Lorell 99552 electric desk riser converts a fixed-height desk into a sit-stand workstation with push-button height changes. It supports a flat-panel display up to 33 inches and a keyboard tray large enough for a keyboard and mouse. Office workers and home users who want to alternate between sitting and standing without replacing their existing desk will find it suited to that purpose. Builders who need a second monitor arm or a larger worksurface than the top platform provides should look elsewhere.

Build integration and freed space

The unit sits on top of any stable work surface and requires no permanent mounting or special tools to install. Its medical-grade electric motor lifts the platform from 5-1/4 inches to 17-1/8 inches off the desk, clearing room underneath for documents or accessories when raised. A built-in USB interface on the top surface keeps charging cables within reach, and the removable keyboard tray can be taken off to free the full platform depth for wider monitors or other gear.

Sustained-load behaviour

The motor is rated for low-noise operation during repeated up-down cycles, so it remains quiet through multiple posture changes in a single workday. An anti-collision sensor halts movement if the riser encounters an obstruction such as a cup or bottle, preventing damage to the mechanism and items on the desk. The steel-and-aluminium frame supports the maximum 33-pound load continuously without sag, and the unit weighs 59.08 pounds, giving it a stable footprint during height adjustments.
