Wire mesh for a vandal-proof seat

A mesh for incorporation in a seat cushion, said mesh comprising a plurality of wire lengths with each wire length being wound to follow a generally helical path so that each wire provides a plurality of convolutions, with adjacent convolutions of adjacent wire lengths overlapping so as to be linked, and wherein each wire length is formed of medium carbon steel and having a diameter between 0.65 mm and 0.75 mm, and wherein the mesh has parameters A, B and C, and wherein the distance A is the distanct between parallel convolutions of adjacent wire lengths, and the distance B is the distance between apexes of adjacent convolutions, and the distance C is the convolution pitch in each wire, with the mesh having pitched parameters and wherein distance A is between 5.0 mm and 10.0 mm, distance B is between 10.0 mm to 18.0 mm, and distance C is between 7.0 mm and 12.0 mm.
