  • a pressure profile can be set for each of various sleeping positions, such as on the back or on the side.
  • real-time, feedback-controlled response of the air pressure controller to increase or decrease the amount of air in one or more air bladder cells 22 can redistribute the air pressure to reshape the bed in response to, for example, a person turning from her back to her side.
  • the air bladder cells 22 in the back zone 50 may be desirable, and less inflation of the air bladder cells 22 in each of the hip zone 50 and shoulder zone 50, when a person rolls onto her side from her back.
  • Such redistribution of inflation of air bladder cells 22 can be achieved by suitably linking the plurality of sensors 192 with control components of the air pressure controller 100 to sense, respond, and provide feedback in a loop that operates to provide for the pre-determined inflation levels.
  • the distribution of inflation of air bladder cells 22 can thus be constantly monitored for each zone, with adjustments automatically made while the person 30 sleeps.
  • the air pressure controller 100 can draw in air from outside the bed through any suitable pathway, including, by example, through an air duct 119 having an opening outside of the bed, including any foam padding.

  • the transformer 172 can be located outside of the support structure 10, such as on a floor on which the support structure 10 rests. In this configuration, all relatively high voltage, and all AC voltage, is decoupled from the support structure 10, and, therefore, physically separated from a person 30 laying on the support structure 10
  • the support structure 10 provides for safe power that can be placed unobtrusively in a place where it is near to, but invisible, to the person 30 and undisturbed from inadvertent impact from outside influences.
