PURPOSE: A flooring member for a cushion is provided to prevent the separation of flooring members and to reduce the influence to binding strength caused by the lowering of binding strength according to a variation of temperature. CONSTITUTION: The flooring member(1) for a cushion comprises a lower projected frame(20) having the appointed width and thickness along the edge of the base and the side of a flooring member(1) for a cushion, and an upper projected frame(30) having the appointed width and thickness to be corresponded to the lower projected frame along the edge of the top and the other side of a flooring member(1) for a cushion. Many coupling grooves(200) are formed on the lower projected frame(20) at regular intervals, and coupling projections are formed on the upper projected frame(30) as much as the number of the coupling grooves(200) of the lower projected frame(20).
