Abstract

An item of seating furniture having a seat and a backrest which are supported in an articulated manner on a frame, and having an operating mechanism for adjusting the inclination of the seat and the backrest. The backrest has a catch member and, when the backrest is inclined from a front position into an inclined rear position, the catch member comes into operative contact with the seat as of a specific angle of inclination of the backrest in such a manner that further inclination of the backrest brings about a simultaneous adjustment of the seat.
