A collapsible table structure comprises a tabletop and a plurality of folding leg assemblies pivotally attached thereto. Each leg assembly comprises a first leg and a second leg connected to each other at a pivot coupling defining an unintruding common axis for movement between an open condition generally resembling an X-shaped configuration and a closed condition wherein the legs, as well as the tabletop, are generally parallelly disposed in a common plane. Each leg is formed by at least two telescopically connected leg sections freely movable through and transversely of the unintruding common axis in moving between extended and retracted positions relative to each other. Each leg includes a locking mechanism for retaining a lower leg section in an extended position. The table structure further includes means for releasing the locking mechanism to facilitate collapsing of the table to its closed condition.
