Abstract
There is provided an apparatus for a folding table assembly comprising a lifting assist center torsion bar assembly, a lift off caster assembly and a stability locking mechanism. A folding table assembly with a lifting assist mechanism provides a lifting assist force during a portion of the folding process of a foldable table from an unfolded use position to a folded storage position. A lift off caster assembly maintains an unfolded table assembly in a stationary position and prevents the unfolded table from wandering or deviating from its original location on the floor. There is also provided a stability locking mechanism that can set the folding table in a folded and stable semi-closed position.
