A folding table, comprising: a. a table top, b. a pair of leg assemblies pivotally connected to said table top, c. said leg assemblies being swingable about their respective pivotal axes between a generally vertical operative position and a generally horizontal inoperative position, and d. spring toggle means for holding said leg assemblies in either of said positions, e. said spring toggle means comprising a coiled tension spring, f. said tension spring being connected at one end to the table top, g. said tension spring being connected at its opposite end to its associated leg assembly below the pivotal axis thereof, h. whereby the tension spring moves across said pivotal axis when the leg assembly is pivoted between its said vertical and horizontal positions, i. each leg assembly comprising a pair of legs and cross-bracing between them, j. whereby said pair of legs and said cross-bracing constitute an integral unit, integrally movable about a common axis extending through both legs, k. there being a single spring toggle means connected to said integral unit, l. the cross-bracing of each leg assembly including a cross-bar which is secured to the upper ends of the two legs of said Leg assembly, above its pivotal axis, m. said cross-bar, pivotal axis and spring connection with the leg assembly defining a three-point isosceles triangle pattern, wherein the pivotal axis represents the apex and the cross-bar and spring connection represent the base angles, n. said cross-bar being situated adjacent the table top and end members provided adjacent said table top with hand grip cutouts allowing said cross-bar to be engageable by the fingers of one hand when the table top is held by the palm of the same hand, o. whereby each leg assembly can be manually swung into operative or inoperative position while the table top is held in horizontal position.
