SUBSTANCE: invention relates to seating furniture, in particular to a chair, with a spring frame, and is aimed at increasing freedom of movement and to improve stacking. The seating furniture, in particular a chair, with a spring frame which is substantially Z-shaped in side view and comprises an upper part of the frame, two lower parts of the frame, and two middle parts of the frame, each of which connects the corresponding lower part of the frame to the upper part of the frame. The upper part of the frame extends from the rear region located on the upper part of the seat frame to the front region of the seat. The lower parts of the frame form the support rails, at least partially parallel to the seat and extending from the front region of the seat to the rear region of the seat. Each middle part of the frame extends from the corresponding lower part of the frame in the rear region of the seat obliquely upwards to the upper part of the frame in the front region of the seat.

EFFECT: distance (a) between the middle parts of the frame in the upper part of the frame is maximum half, preferably maximum one third of the width (A) of the seat in its front region, to provide during the use of seating furniture at least partially an ergonomically favourable lateral displacement of the upper part of the frame relative to the lower parts of the frame without substantial separation of the lower parts of the frame from the floor.
