Abstract: The invention relates to seating furniture comprising two frames arranged at a distance to each other on a support, between which frames a seat part and a backrest part can be mounted, and the frames have one upper frame part and a lower frame part each which mechanically immobilize the seat part and the backrest part a the sides thereof. The upper frame part and the lower frame part are clamping elements that can be braced with each other. At least one clamping element has a laterally extending recess on each edge which recess forms a frame groove in which a respective engaging element provided on the edges of the seat part and of the backrest part can be mounted by way of a frictional connection to the upper frame part and the lower frame part. The recess has an undercut portion which forms a stop for holding the clamped engaging element by a form fit.

Abstract: The invention relates to seating furniture comprising two frames (2) arranged at a distance to each other on a support (1), between which frames a seat part (3) and a backrest part (4) can be mounted, and the frames (2) have one upper frame part (6) and a lower frame part (7) each which mechanically immobilize the seat part (3) and the backrest part (4) on the edges thereof. The support (1) contains a horizontal bar (11), extending between two legs (5), on which the frames (2) can be mounted as a terminal frame or intermediate frame via respective frame bases (12). The bar (11) comprises a linking piece (13) which is put on a detachable, form-fitting pin connection (14) together with the frame base (12) of a terminal frame and a leg (5) in a certain order.
