A computer desk comprises two support frames similar in construction to each other, an ascendible and descendible main desk top supported by the support frames, and an ascendible and descendible auxiliary desk top supported by the two support frames. The support frames are formed of a base tube, two support tubes, two movable support rods, a fitting member, a retaining member, an adjustment shaft, and an adjustment shaft, and an adjustment knob. The main desk top and the auxiliary desk top are mounted on the top ends of the movable support rods which can be raised or lowered by turning the adjustment knob clockwise or counterclockwise.
