FlexiSpot Height-Adjustable Standing Desk Riser for Corner Desk, 41"W, Black

Break up time spent sitting and working by creating a sit-stand workspace in your home or office. Place this height-adjustable standing desk riser directly on top of your existing desk, squeeze the lever to move the desk into 1 of the 12 height positions and set up your keyboard and mouse on the tray - there's plenty of room for both. The gas springs (pneumatic pistons) let you switch between sitting and standing with ease and control.
