A convertible mat (10) is provided and comprises a generally planar base (20) and a border extending around the base, the border comprising border sections (25, 26, 27, 28) joined together by webs, the webs being single, substantially non-folding web sections (35, 36, 37, 38) which cause the border sections to be movable together between a first position in which they are coplanar with the base and a second position in which they are inclined whereby to form a tray. |
