Place this Realspace Standing Desk Converter on your worktable or desk to transform it into an active workstation. With the pneumatic lift-assist, you can easily transition from sitting to standing and back again, as the riser can move between 5.1" and 19.3'' above your work surface. You'll also be able to maintain a comfortable typing position because the removable keyboard tray moves in accordance with the top surface. Plus, 3 USB ports are located under the desk surface to allow you to easily connect your peripherals.
