The backrest is rotatable about 90 degrees. An auxiliary function surface is rotated upto 180 degrees and forms the backrest in different positions. The surfaces are rotatably supported and positioned together in such a manner that two different large surface dimensions are produced to take an upright sitting position and a lying position.</p>
