A folding sectional table assembly includes a pair of table sections, each o f which includes a table top and leg structure pivotably mounted to the table top. Each leg structure includes a pair of upper tubular members pivotably mounted between a pair of apron members secured to the underside of the table top, for providing pivoting movement of the leg structure relative to the table top. A torsion bar assist mechanism is disposed within selected ones of the upper tubular members of the leg structures, and includ es a torsion bar located within an internal passage defined by the upper tubular member. Each end of the upper tubular member is pivotably mounted to a hub member secured to one of the apron members. One end of the torsion bar is engaged with a torsion bar retainer mounted to one of the hub members, and a torsion bar driver is mounted to the upper tubular member at a location spaced from the torsion bar retainer, and engages the torsion bar t o twist the torsion bar during pivoting movement between the table top and the leg structure. A pneumatic cylinder assembly is interconnected with each table section for cushioning t he table sections as the table sections are lowered, and also to provide a spring biased assis t in lifting the table sections for folding. At least one pair of hinge plates interconnect t he table sections. Each cylinder assembly is interconnected at one end with a hinge pin which pivotably interconnects the hinge plates, and at the other end to one of the leg structures.
