Ergonomic Sit-Stand Converter

This pneumatic desk converter transforms an existing desk into a height-adjustable sit-stand workstation. It supports one monitor up to 30 inches and 28.7 lb with a steel frame and engineered wood base. The one-touch lever allows smooth transitions between sitting and standing positions. It suits home or office users seeking improved posture and comfort.

From Fixed Desk to Adjustable Workstation

The unit replaces a static monitor setup by adding 16.6 inches of vertical travel via a pneumatic spring mechanism. The jump is worth it when you want to alternate positions throughout the day without replacing your entire desk. It fits on surfaces at least 33.70 inches wide and 26.80 inches deep. The 6.30-inch folded height keeps the profile low when seated.

Check Desk Space and Monitor Compatibility

Verify your current desk top measures at least 33.70 by 26.80 inches to accommodate the base footprint. Confirm your monitor weighs no more than 28.7 lb and does not exceed 30 inches diagonally. Ensure the 421 mm maximum height suits your standing eye level. The package includes the pneumatic arm, keyboard tray and mounting hardware.

Questions about this item

How much desktop depth does the 26.80" base require?

The steel base measures 26.80" deep, so your existing desk must provide at least that much clear depth to sit flat and stable.

What is the correct way to engage the pneumatic lever for one-touch height changes?

Squeeze the lever while gently guiding the platform; releasing the lever locks it at any height up to 16.6 in. Forcing the platform without the lever engaged is the common error.

When should the pneumatic spring be checked or replaced?

If the 28.7 lb capacity feels heavier or the platform drifts down after the lever is released, the spring has lost pressure and needs service.
