Abstract: A work table having a table top with a uniform planar upper surface, truncated corners and a frame on the underside thereof. Depending from the frame are corner collar members with a respective tapered bore therein. The table top is supported by corner support posts each of which include recesses at least adjacent to the respective upper ends thereof. A pair of matingly engaging sleeve sections clamp around each support post. The sleeve sections, when joined, provide a corresponding tapered exterior surface. A protusion, internally of the sleeve sections, locks into an associated recess on the support posts. The corner collar members receive the respective pairs of sleeve sections and urge them into secure clamping engagement of the support posts. The work table can include a frame support therebelow or an adjustable shelving therebelow.
