Abstract: There is described a convertible table system which has a fixed central portion and leaves along at least two adjacent edges. The leaves fold from an operative position where they are substantially co-planar with the table top to a stored position where they are rotated through 180.degree. to be against or adjacent the bottom of the fixed part of the table. The leaves are retained in the operative position by sliding supports. These supports have pendant portions to be sufficiently robust to withstand the usage to which the table might be put. The pendant portions are able to be retracted out of the paths of the leaves when they are folded to the stored position. The angle of mounting of the sliding supports allows this to occur. The leaves are held in the stored position by a catch which can be magnetic or frictional or other.
