ABSTRACT:
A foldable workbench made of a pair of U-shaped (when viewed from the above) frame works connected to each other, each frame work being formed with rear frame section and two side frame sections which are pivotally connected to the rear frame section so that the two side frames can be folded one on the other. A top panel is pivotally connected to the upper end of the rear frame section so as to be raised to a horizontal position. The height of vertical posts that make the frame work is adjustable by way of locks inserted into holes opened in the posts.
