Third-leg base for sit-stand desk

This third-leg base expands a Lorell two-tier sit-stand base to support a return worksurface. It is designed for office workers who need an L-shaped height-adjustable desk. The metal frame adjusts in width and height to fit different return sizes. A dual-motor system raises the leg smoothly and quietly.

Return worksurface width and depth limits

The base only works with return worksurfaces that measure 42 to 48 inches wide and 24 inches deep. Surfaces outside that range cannot be mounted. The leg height travels from 26.57 to 45 inches at 1.3 inches per second. The frame capacity is 275 pounds, so heavier loads are not supported.

Assembly required with anti-collision safety

Assembly is required before use. The control box synchronises both legs to compensate for uneven loads. The controller stores four height presets and includes an anti-collision feature that stops movement if an obstacle is detected. Buyers without tools or time for assembly should note this requirement.

Questions about this item

Should I choose this third-leg base for a 42 in return or a 48 in return?

The base adjusts in width to fit returns from 42 in to 48 in wide and 24 in deep, so either size works.

What does the 275 lb capacity mean when the base is under my worksurface?

The metal frame is rated for 275 lb total load, and the dual motor compensates for uneven weight while lifting.

How does the dual-motor system affect height changes on this base?

Two synchronized motors raise the leg from 26.57 in to 45 in at 1.3 in per second with anti-collision protection.
