What this base does

The Alera AdaptivErgo pneumatic table base raises and lowers a worksurface between 26.25" and 39.63" without electricity. A 13" lift range lets you alternate between sitting and standing with one touch. The black powder-coated steel frame includes cross bars for stability and adjustable glides for uneven floors.

Replacing a fixed desk

It retrofits most common tops from 59" to 72" wide and 24" to 30" deep, adding ergonomic height change to an existing surface. The jump is worth it when you want posture variety but lack a power outlet nearby. Buyers needing lift beyond 85 lb including the top should look elsewhere.

Sustained daily use

Pneumatic lift-assist operates smoothly through repeated cycles without motor heat or power draw. The durable steel frame resists racking under the rated 85 lb capacity during long work sessions. Leveling glides maintain a stable platform on imperfect floors over time.

Questions about this item

What table-top sizes does the 28.35" deep base support?

The base fits most common tops from 59" to 72" wide and 24" to 30" deep, matching the 28.35" frame depth.

How is the pneumatic lift installed, and what step is often missed?

Mount the base to a pre-drilled top with the included hardware, then set the adjustable leveling glides so the frame sits level before first use.

What maintenance does the pneumatic cylinder need over time?

No routine service is required; if the 85 lb lift capacity ever drops, the sealed cylinder must be replaced as a unit.
