Fitting for a piece of seating furniture, comprising: - a base for arranging on an underlying surface in a fixed position or such that it can be rotated about a vertical axis, - a carrying part for a seat surface, it being possible for said carrying part to be moved in relation to the base between a front relative end position and a rear relative end position, - a front and a rear link plate (30, 40), wherein - the front link plate can be pivoted in relation to the base about a first axis, which is fixed in position in relation to the base and the front link plate, and can be pivoted in relation to the carrying part about a second axis, which is fixed in position in relation to the carrying part and the front link plate, and - the rear link plate can be pivoted in relation to the base about a third axis, which is fixed in position in relation to the base and to the rear link plate, and can be pivoted in relation to the carrying part about a fourth axis, which is fixed in position in relation to the carrying part and to the rear link plate, and - a leg-rest part, which can be pivoted between a stowage position beneath the base and a functional position in front of the base and of which the position relative to the base is positively coupled to the position of the carrying part relative to the base such that the leg-rest part assumes its functional position when the carrying part is arranged in its rear relative end position and assumes its stowage position when the carrying part is arranged in its front relative end position, wherein - a first spring is provided between a first and a second point of articulation (81, 82) on the carrying part and on the base part, said spring causing the carrying part to be forced in the direction of its front relative end position, characterized in that - a second spring is provided, and this second spring, on the one hand, is fastened on the carrying part at a third point of articulation, which is spaced apart from the first point of articulation and the second point of articulation, and, on the other hand, is fastened on the base part at a fourth point of articulation and, as the leg-rest part approaches its stowage position, acts between the carrying part and the base part such that the leg-rest part is forced in the direction of its stowage position. -
