A piece of seating furniture according to one of the preceding claims, wherein a connecting member (30) is arranged at the upper part of the frame (11) in the front area of the seat surface (20), wherein the front area of the connecting member is inclined towards the surface formed by the upper part of the frame (11).
A piece of seating furniture according to the preceding claim, wherein the connecting member (30) comprises a fixing device so that auxiliary equipment, particularly arm rests (40) and/or writing tablets can be attached to the connecting member (30).
A piece of seating furniture according to one of the preceding claims, wherein the bottom side of the seat surface (20) comprises an opening (50), into which the portion of the upper part of the frame (11) in the rear area of the seat surface (20) can at least partially be arranged in a form-fitting manner.
A piece of seating furniture according to the preceding claim, wherein a force is applied in case of a connection, preferably a bolted connection, of the stable surface (35) with the connecting member (30), tightening the part of the upper part of the frame (11) arranged in the opening against the opening (50).
A piece of seating furniture according to one of the preceding claims, wherein the frame (10) is formed in one part.
A piece of seating furniture according to one of the preceding claims, wherein the lower parts of the frame (12a, 12b) are connected by means of a cross member in the rear area.
A piece of seating furniture according to one of the preceding claims, wherein the middle parts of the frame (13a, 13b) are connected by means of a cross member.
