Encourage interactive classrooms and engaged learning with StarTech.com mobile sit-stand workstations. These sit-stand desks allow students to set up their learning environments to suit their needs. The workstations can easily be adjusted from a sitting position to a standing position with no disruptions to the class. Teachers can arrange and rearrange their classrooms according to their lessons, they can set up individual desks for tests or lectures, or group two or more desks together for projects.

Moving between sitting and standing throughout the day brings many health benefits, from increased circulation to reduced fatigue. The sit-stand workstations make it easy for students to change their positioning throughout the day, keeping them attentive and focused. Giving students the freedom to stand when needed can also help to reduce anxiety and restlessness. Students can adjust the desk to any height between 29.5' (750 mm) and 45' (1150 mm), they simply need to squeeze the lever located under the work surface, and then move the workstation up or down.

There are no preset heights, so each student can find the precise height they need to work most comfortably. The large surface area of the desktop, 24 (600 mm) x 31.5 (800 mm), provides ample room for all schoolwork and supplies such as textbooks, pens, and other stationery.

The workstations can also be combined with monitor mounts to add displays. The work surface also provides enough room for a keyboard and mouse. Note: If more than 10 lb. (4.5 kg) of weight is added to the work surface, some manual force will be needed to raise the desktop.
