Abstract (en)
[origin: EP0311993A2] A sitting or lying system is proposed, which consists of sitting or lying furniture and has several pressure cushions which can be filled with air or the like. In order to improve further the sitting or lying characteristics, in particular to guarantee sitting or lying which does not cause tiredness, a pulsating pressure medium acts on the pressure cushions (2), and the quantity of compressed air flowing in and flowing out and the time period are controlled. <IMAGE>
