Abstract

A desk according to one embodiment of the present invention includes an upper panel, a support leg, a support member, a movable panel and a vertical panel. The upper panel is coupled to an upper end of the support leg. The support member extends from the upper panel. The movable panel has an upper end movable along the support member and a lower end movably placed on the upper panel. The movable panel is movable between a first position inclined with respect to the upper panel and a second position vertical to the upper panel and between the first position and a third position parallel to the upper panel. The vertical panel is rotatably joined to the support member. A lower end of the vertical panel is movably placed on the movable panel. The vertical panel moves along with the movement of the movable panel.
