Seating furniture comprising a seat part, a back part, a chassis and an at least two-part leg rest pivotably connected to the seat part and/or to the chassis, - the parts of the leg rest being displaceable relative to one another during the pivoting, - the seating furniture being adjustable between a sitting and a lying position, - for which purpose the leg rest is pivoted in substantially below the seat part in the sitting position and is pivoted out in front of the seat part in the lying position in such a way that the seat part is extended by the leg support, - part of the leg rest being formed by a telescopic leg rest element which is pulled in when the leg rest is pivoted in and pulled out to increase the length of the leg rest when the leg rest is pivoted out, wherein, - in the sitting position of the seating furniture, a first and/or a second articulation lever are articulated to the seat part and/or to the chassis, and a longitudinal axis, formed between the two end articulation points (18, 19) of at least one of the first and/or the second articulation lever, is arranged oblique to the seat part, and thus the end articulation point of this articulation lever facing the seat part is positioned closer than the end articulation point of this articulation lever remote from the seat part to a vertical plane spanned by the seat part front edge, - a third and a fourth articulation lever having, in the sitting position of the sitting furniture, an orientation in which a longitudinal axis, formed between the two end articulation points (20, 21) of at least one of the third and/or the fourth articulation lever, is arranged oblique to the seat part, and thus the end articulation point of this articulation lever facing the seat part is positioned closer than the end articulation point of this articulation lever remote from the seat part to a vertical plane spanned by the seat part front edge, - the third and fourth articulation lever being respectively connected via their end articulation points (20, 22) facing the seat part in the sitting position of the seating furniture to a fifth articulation lever, - a coupling lever being articulated to the first and/or second articulation lever and/or to the third and/or fourth articulation lever, and - a control lever being articulated to at least one of the first, the second, the third and the fourth articulation lever, - the fifth articulation lever being connected both to the third and to the fourth articulation lever and, via its free end in an articulated manner, to the telescopic lag rest element. - the parts of the leg rest being displaceable relative to one another during the pivoting, - the seating furniture being adjustable between a sitting and a lying position, - for which purpose the leg rest is pivoted in substantially below the seat part in the sitting position and is pivoted out in front of the seat part in the lying position in such a way that the seat part is extended by the leg support, - part of the leg rest being formed by a telescopic leg rest element which is pulled in when the leg rest is pivoted in and pulled out to increase the length of the leg rest when the leg rest is pivoted out, -

the third and fourth articulation lever being respectively connected via their end articulation points (20, 22) facing the seat part in the sitting position of the seating furniture to a fifth articulation lever, - a coupling lever being articulated to the first and/or second articulation lever and/or to the third and/or fourth articulation lever, and - a control lever being articulated to at least one of the first, the second, the third and the fourth articulation lever, - the fifth articulation lever being connected both to the third and to the fourth articulation lever and, via its free end in an articulated manner, to the telescopic lag rest element.
