A strap-tightening structure for a furniture item having a frame that supports an elongate strap. The elongate strap includes a rearward section that overlies the back rest of the furniture and a forward section that overlies the seat section. A rearward end of the elongate strap overlies a transversely disposed rearward end of the frame and is secured against longitudinal displacement when the forward end of the elongate strap is pulled taut at the forward end of the furniture. A pair of tensioning belts are secured to a forward end of the elongate strap. Each of the tensioning belts is disposed in overlying relation to a transversely disposed forward end of the frame. A pair of releasable buckles is secured to a bottom side of the elongate strap and adjustably engages the tensioning belts so that the elongate strap can be pulled taut whenever it develops a sag. |
