An apparatus having a fabric and method of forming thereof. The fabric's load bearing surface for supporting a load, comprising: at least one layer(s) (L<SUB>n</SUB>) wherein n=0, -1, -2, . . . -i, wherein n=0 represents the at least one layer(s) (L<SUB>n</SUB>) of the load bearing surface that contacts the load. An n=-1, -2, . . . -i, represents successive underlying at least one layer(s) (L<SUB>n</SUB>) of the load bearing surface. An n=-i, represents a bottom underlying at least one layer(s) (L<SUB>n</SUB>). The fabric consists essentially of a polyurethane fiber and a fiber that is chemically different from the polyurethane fiber, and wherein the fabric has been stretched to the point just before encountering the Young's Modulus. The method comprising: cutting the fabric to a predetermined pattern; and stretching the fabric to the point just before encountering the Young's Modulus.
