HeightMaster HM-500

The catalog description lists a maximum load of 50 pounds, which is about 22.7 kilograms. That total should include the monitor, keyboard, computer, speakers, and any other equipment placed on the work surface.

It is an extra-large electric desk converter for raising a workstation from sitting to standing height. The broad surface is especially suited to drafting, design, and multi-device setups that need more room than a small monitor riser.

Its 50-pound capacity and large work surface may accommodate a multi-device layout, but the exact answer depends on the monitor stands and their combined weight. Check the platform dimensions and keep heavy items centered to avoid instability.

A converter lifts the existing desk surface and leaves the original desk underneath, while a motorized standing desk raises the entire tabletop and frame. The converter is often easier to add to an existing office, but it can reduce legroom and add weight to the original desk.
