A table includes an upper flat board having the edge folded to join the edge of a lower shaped board. The lower shaped board has lower side strengthening ribs radially extending from a central connecting part. An inner rod is connected to the central connecting part from an upper threaded portion, and connected to a base member from a lower threaded portion. An outer tube is placed around the inner rod with a top abutting the central connecting part. A plastic sleeve is passed into a lower end of the outer tube with the central hole encircling the inner rod, and has a lower end flange interposed between the bottom of the outer tube and the upper side of the base member. Thus, the boards are held at an elevated position by both the inner rod and the outer tube.
