A motorized desktop stand unit having a main surface assembly designed to accommodate a monitor or laptop and a secondary surface assembly designed to accommodate a keyboard. The desktop stand unit also has a frame assembly having an upper frame and a lower frame. An elevation mechanism is provided between the upper frame and lower frame. A switch provided in the main surface assembly, when actuated, causes the elevation mechanism to adjust the space between the upper frame and lower frames, changing the height of the main surface assembly.

A height-adjustable stand unit including a main surface assembly configured to support computing equipment. The stand unit includes an upper frame coupled to the main surface assembly, a lower frame adapted to rest on a work surface, and a scissor-lift elevation mechanism disposed between the frames. The scissor-lift assembly comprises two pairs of elongate arms in crisscross configuration with pivotal connections at central pivot points, enabling stable vertical adjustment of the main surface assembly for ergonomic positioning.
