<p>The invention relates to a body-supporting furniture frame in which two opposed longitudinal members have mutually parallel cross-pieces disposed therebetween. At least the edge portions of the cross-pieces are provided with longitudinal apertures in which a wire or bar is loosely received. The wires or bars, and the cross-pieces generally, are longitudinally curved so that they flex when a load is applied thereto. The cross-section of the apertures and the crosssection of the wires are mutually shaped and sized to prevent rotation of a wire or bar in an aperture through an angle exceeding 90 degrees. In this way dislocation of the wires or bars in the cross-pieces is prevented.</p> |
