A knock-down type workbench including a three piece support structure assembly which may be assembled in rigid form entirely without the use of nails, screws or other fastening means. The knock-down workbench includes a plurality of table tops which have different functions and are interchangeable. The panels of the workbench are interlockingly stressed to create a structurally tight workbench held together by forces created by the interlocking parts. Thus, the workbench may be lifted or severely jolted without fear of it collapsing.
