Abstract: A sleeper sofa having a bridge joint to inhibit bowing between frames in a sleeper position is provided although other folding articles are contemplated. The sleeper sofa has a first frame section and a second frame section foldable/pivotable from a first sitting position to a second sleeping position. When in the sleeping position, the bridge joint extends under and between the first and second frame section to provide support to inhibit bowing at the junction between the first and second frame section. The bridge joint includes a pivot axle and an anti-buckling member coupled to a pivot guide having a track. The anti-buckling member travels in the track as the first and second frames are unfolded about the pivotal axle.
