An article support such as a shelf or a table top has a frame that, in its heated state, slidably receives a glass or plastic planar sheet into grooves along two opposing edges of the frame, until an end of the sheet abuts a third edge of the frame that joins the two opposing edges. The edges of the frame have lips that rest on a portion of the top surface of the sheet. When cooled, the frame contracts such that the edges of the sheet are tightly engaged within the grooves of the frame and the lips tightly abut the top surface of the sheet, thereby creating an article support that resists spills around its periphery. The frame may be reheated to expand the material of the frame, permitting removal of the sheet from the frame. Thus, the frame and the sheet may be recycled.
