A desk for use as a computer workstation has a generally planar work surface having first and second portions; a monitor storage space beneath the first portion on and a monitor support that is movable between a retracted attitude iii which the support is in the storage space and an extended attitude in which the support extends above the work surface. The first portion is movable between a closed position in which the first portion forms a part of the generally planar work surface and overlies the storage space to prevent movement of the support and an open position in which the first portion a flows movement of the support between the retracted and extended attitudes. When the support is in the extended attitude, a monitor attachment coupled thereto is movable along horizontal and vertical axes to enable the position of the monitor above the work surface to be adjusted.
