The cubicle, cubicle desk, office cubicle or cubicle workstation is a partially enclosed workspace, separated from neighboring workspaces by partitions that are usually 6-7 feet tall. Its purpose is to isolate office workers from the sights and noises of an open workspace so that they may concentrate without distractions. Cubicles are composed of modular elements such as work surfaces, overhead bins, drawers, and shelving, which can be configured depending on the user's needs. Installation is generally performed by professionals, although some cubicles allow configuration changes to be performed by users without specific training.
