To provide a product having antislip action and produced by using a new woven fabric having antislip action and air permeability and provide an antislip method.

The antislip sheet 1 constituting the surface of an antislip cushion S1 is woven by leno weaving by using an uncoated polyurethane yarn C having high frictional resistance as the warp. Accordingly, a number of protrusions and recesses are formed on the surface of the antislip sheet 1 to exhibit excellent antislip action. The open cavities formed by the gap between the wefts and the numerous protrusions and recesses facilitate the passage of air to prevent the skin from becoming stuffy even if the antislip cushion S1 is brought into close contact with the body.
