A retrofit kit formed by pairs of telescoping legs (28) and a tool anchoring platform for a collapsible leg structure (12, 14) for a metal bench (10) including a T-shaped brace rod (38) having one end of its stem pivotally connected to the underside of the bench and its other end extending between and lockingly engaged with the depending end portion of a pair of the legs (12, 14). A strut (58), pivotally connected with the stem of the brace rod (38), is slidably engaged with a track bracket (50) secured to the under-surface of the bench to limit downward movement of the brace rod with respect to the bench. Links connecting the legs to the strut (58) collapse the legs to a folded position under the bench when the brace rod is manually released from the legs and moved toward the undersurface of the bench.
