The standing desk in question is the descriptively titled Wall-Mounted Standing Desk. It's comprised of a wooden spine which is permanently attached to the wall, with grooves set into it at regular intervals. These grooves are used for the two shelves which turn it into a standing desk; a small shelf is set at head height for a laptop or tablet, with a larger shelf set at chest height for keyboard, mouse, and a beverage of your choice.
The shelves can be placed in whichever groove best suits the individual user, being temporary locked in place using a carriage bolt. When the standing desk is not being used, the shelves can be removed and stored out of sight. This leaves just the spine visible as a conversation starter, that the more creative among us would be able to describe as a piece of modern art.
The wooden spine measures 24 x 3 x 2.25 inches (61 x 7.6 x 5.7 cm), with the lower shelf measuring 23.5 x 15.5 in (59.7 x 39.4 cm) and the upper shelf measuring 11.5 x 15.5 in (29.2 x 39.4 cm).
The Wall-Mounted Standing Desk is available in light or dark wood, and is priced at $245. Drywall anchors and wood screws are provided for easy installation on a range of wall materials.
