    • A height adjustment system for a desk or workstation comprises plurality of height adjustable legs each having a first part in the form of a hollow column and a second part movable relative to the first part in a vertical direction. The second part of each leg includes a gearbox housing containing a crown gear provided on a vertically extending rotatable shaft and at least one pinion gear engageable with said crown gear. The gearbox housing includes ball bearing race assemblies for the crown and pinion gears which enable the height of two or more legs to be adjusted simultaneously by a single winding mechanism. The leg also includes a self-adjusting linear bearing between telescopically movable parts of the leg. The height adjustment system may also include a duct for cabling, a cable tray and a hinged duct cover pivotally attached to the top member.
