Abstract: A mattress is provided with a plurality of inflatable cushion elements each having two cushion chambers. Air or filling pressure medium can be regulated by a device with a pump. The pump is coupled to a control in which filling pressure values and/or arithmetical operations are programmed. The pump is also provided with sensors. This enables the filling pressure to be increased or reduced on the basis of the weight of a lying person loading the cushion elements until a predetermined value corresponding to a specific degree of hardness or comfort for lying is attained. Simple pressure on a key on a remote control is therefore sufficient to bring about completely automatic adaptation to the lying person, regardless of whether he or she weighs 40 or 150 kg. This intelligent mattress offers an absolute maximum of individual comfort for lying with a minimum of effort for operation.
