A seat construction comprising a frame having first and second spaced rails and a seat suspension mat comprising covered first and second border wires and a plurality of longitudinally spaced transversely extending spaced wires having their ends attached to the border wires, said first border wire being attached to the first rail and the second border wire being attached to the second rail. First and second auxiliary coated wires extending longitudinally and generally parallel to the border wires. Each transversely extending wire is wound around each of the auxiliary longitudinal wires, thereby defining a first portion extending upwardly from the first border wire to the first auxiliary wire, a second portion extending from the first auxiliary wire to the second auxiliary wire, and a sinuous portion extending from the second auxiliary wire to the second border wire. When a load is applied generally perpendicular to the general plane of the suspension mat, the wrapped portions of the wire about the auxiliary longitudinal wires are wound to varying degrees about the auxiliary longitudinal wires and the sinusoidal portions of the wires extend to provide continued resilient suspension.
