A folding leg apparatus for an article of furniture having a top and a support leg movable between an extended and a folded position comprises a mounting plate configured for attachment to the top of the article of furniture and including a pair of mounting flanges extending along opposite sides of the mounting plate, an upper pivot rod attached to the support leg adjacent the top end, a first pivoting connection between each end of the upper pivot rod and a corresponding one of the pair of mounting flanges and a second pivoting connection between the support leg and a corresponding one of the pair of mounting flanges offset on the support leg from the upper pivot rod. A latch mechanism is provided that includes a pair of pivot arms, each pivotably mounted to a corresponding one of the pair of mounting flanges and positioned between the flanges. Each of the pivot arms includes an actuator plate positioned between the flanges and adapted to be manually pressed. The actuator plates are space apart to receive the support leg passing therethrough. Each of the pivot arms further defines a locking notch configured to capture the upper pivot rod therein when the support leg is in its extended position and the pivot arms are in a locking position. A pair of torsion springs are each operatively anchored to a corresponding one of the pivot arms to bias the pivot arms to the locking position and operable to resist rotation of the pivot arms when the corresponding actuator plate is manually pressed, each of the torsion springs positioned between the mounting flanges.
