Corner standing desk converter

The Mount-It MI-7958 is a corner standing desk converter designed for cubicle corners or standard desktop placement. Its triangular shape fits most corner configurations while providing a height-adjustable work surface. The unit transforms an existing fixed-height desk into a sit-stand workstation without replacing the entire desk. It suits office workers who want to alternate between sitting and standing positions throughout the day.

Gas spring height adjustment

A dual gas spring mechanism handles height changes smoothly across a 6.5 to 16 inch range. The top platform measures 48 by 33 inches and supports up to 33 lbs for monitors, laptops or desktop towers. A separate keyboard platform measures 39 by 12.5 inches and carries up to 4.5 lbs. The converter sits on your current desk surface and requires no permanent mounting or modification to the existing furniture.

Ergonomic sit-stand conversion

The bundled gas spring handle enables one-handed height adjustment so you can switch postures without interrupting workflow. Two independent platforms keep the monitor at eye level while the keyboard tray stays at typing height, supporting neutral wrist and neck alignment. The converter ships fully assembled and ready to place on any stable desk, delivering immediate ergonomic benefits without tools or installation time.
