ABSTRACT:
A foldable table frame includes a table support apparatus which includes a set of our tabletop support arms slidably connecting at their inner, crossing ends to two opposing tabletop support arm holders and at their outer ends pivotally connecting to four frame top joints, such that each set of two tabletop support arms opposedly face with each other and are parallel to the other set of the two tabletop support arms. The table support apparatus further includes a pair of table support pillars for providing greater stability for the table support apparatus for supporting a foldable tabletop, each connecting at its upper end between the respective pair of tabletop support arm holders and at its lower end to a foldable table frame body. The foldable table frame is arranged to allow being pushed together in one motion to fold up the foldable table frame or pulled open to unfold the foldable table frame for the foldable tabletop to mount thereon.
