A height adjustable desktop includes an upper work surface platform, and a base platform, which configured to rest on an existing desk, platform, surface, or table. The height adjustable desktop further includes a height adjustment mechanism that includes two sets of two arms that connect at pivot points along their lengths so that the arms configured to move in a scissoring motion to raise and lower the upper work surface platform. The height adjustable desktop also includes two actuators that apply a force to the two sets of two arms, the actuators each containing feedback sensors that provide data regarding the current position and distance each actuator has extended, retracted or moved.

According to examples, an apparatus may include a guide system including a first gear having teeth to engage with a first set of teeth, a second gear having teeth to engage with a second set of teeth, the first gear and the second gear to rotate in concert with respect to each other, and a first glide mechanism to slidably contact a first channel. In addition, the apparatus may include a panel to employ the guide system to be slidably mounted to a base structure, wherein the first gear and the second gear are to impede rotation of the panel about a first axis and the first glide mechanism is to impede rotation of the panel about a second axis.

A pullout lectern and shelf device are disclosed. The lectern is an angled or anglable substantially flat surface or portion thereof which is unobstructed in such a manner as to be designed for paper, books, small items, arms, or the like to rest thereon. A base unit has a top section, middle section, and bottom section, wherein each section has a different circumference than an adjacent section in one embodiment of the disclosed technology. The base unit has at least one shelf, and in some embodiments, three shelves. The lectern is slidably removable from the bottom section. An angle support mechanism attached to the lectern is operable to change an angle of the lectern relative to the base unit. The lectern has a mathematically similar shape to the base unit in some embodiments, this shape being one with at least six sides such as a hexagon or regular hexagon.

An adjustable keyboard tray includes a desk mount configured to secure the adjustable keyboard tray to a desktop, a slide including a fixed rail attached to the desk mount and a slidable rail slidably mated with the fixed rail, a keyboard platform mount attached to the slidable rail with a keyboard platform mount pivot, and a keyboard platform attached to the keyboard platform mount, the keyboard platform being slidable relative to the desk mount via the slide and tiltable relative to the slide via the keyboard platform mount pivot.
