Abstract: An office desk system or work station is based on a structural supporting frame or chassis made up of two spaced parallel end gables and a beam extending between the gables at the rear edge of a work top. Each gable is a welded assembly of steel channels and the beam is a steel generally box section member. Decorative cladding is attached to the frame to provide the desk with the required external appearance. The beam has two internal wiring channels so that electrical power and telecommunication services can be provided directly at the work surface of the desk. Disconnectable couplings are provided between the beam and gables and each gable is provided with several coupling points so that many different desk system or work station configurations can be assembled from the same basic components.
