Abstract: Table top support arms are pivoted to a base frame and extend above and below it. The lower ends of the support arms are connected through linkages with picnic table bench sections having sliding engagement with the base frame. When the support arms are tilted in one direction on their pivots, the linkage draws the bench sections together to produce a single bench bottom and the table top which is pivotally supported on the support arms is swung to a back rest forming position. Stop elements on the support arms limit the swing of the support arms and also position the back rest and table top component.
