  • the present invention relates to adjusting pressure and more particularly, to adjusting the pressure in a pocket in response to stress areas of an individual.
  • Relieving stress in the body can provide for a more restful sleep and stress can be relieved by increasing or decreasing pressure in various spots of the body.
  • Some conventional mattresses allow the firmness to be adjusted; however, the firmness is manually adjusted based upon how a person is feeling and not based on measured parameters, for example, pressure, in the body which corresponds to stress.

  • Sensors 102 (or any device capable of measuring pressure), within pockets 1 12, detect stress areas of an individual sitting or lying on mattress 101 by measuring the individual's body pressure at the location of each of pockets 1 12.
  • Sensors 112 may be located on the mattress, in a layer of the mattress or the mattress toppers.
  • a stress area is an area of an individual's body that is receiving too little or too much pressure from mattress 101. If a stress area is detected, the volume, or spring tension, in the corresponding pocket or zone, is adjusted to alleviate the stress.
