Abstract
The invention relates to a chair with a seat, a base support and a backrest, wherein the seat is mounted on the base support so as to be pivotable about a first pivoting axis and the backrest is mounted on the seat so as to be pivotable about a second pivoting axis. The two pivoting axes are arranged so as to be displaceable relative to one another in order to be able to change the seat depth.
