ABSTRACT:
A work surface is supported for adjustment in a vertical direction by a device which includes a base and an angle post upstanding therefrom with a column mounted for sliding movement in engagement with the post. The work surface is mounted on an upper end of the column which is moved slidably by manual movement of a ratchet type mechanism and which is maintained in engagement with the post by an arrangement which provides for three dimensional as well as torsional stability. The work surface is provided with a further degree of mobility by mounting an axle and wheels on the base in such a way that the axle is moveable between a rest position in which the base rests on a floor and a mobile position in which the base is spaced above the floor by the wheels which ride thereon.
