ABSTRACT:
A chair has a seat and a back rest supported by a back rest support to be vertically adjustable, the back rest support being connected, on the one hand, to the back rest and, on the other hand, to the seat. In order, firstly, to enable a simple and elegant vertical adjustment and, secondly, to design the back rest and the seat to be suitable for packaging and, therefore, for dispatch, the back rest support is telescopically composed of an inner and an outer support member, and an interlocking device for the detachable interlocking of the two support members in varying positions, relative to one another, is provided on the back rest support.
