Definitions

  • This invention relates to a mattress having an adjustable contour.
  • Standard off-the-shelf mattresses and pillows are not designed to satisfy individual needs for contour and hardness and accordingly fail to provide adequate support to the spine and neck of the user.
  • many elderly people have trouble finding a mattress and pillow on the market which would fit 100% their needs for relief from shoulder pain, neck pain, back pain resulting from improper support to their body because of the less-than-optimum contour and hardness of their mattresses.
  • the prior art includes air-bag-type mattresses for pressure sore relief and with low contact pressure for comfort.
  • adjustable bed support frames like those commonly used in hospitals
  • the present invention aims to provide an improved mattress. More particularly, the present invention aims to provide an improved mattress that enables custom modification of the mattress contour in accordance with the preferences and needs of the individual user.
  • the term “contour” is used herein to mean a profile of an upper surface of a mattress.
  • the contour is variable in accordance with the operation of multiple mattress height actuators and is user adjustable.
  • Mattress contour may be adjustably variable in just one dimension, along the length of the mattress, or in two dimensions, including both length and width.
  • the present invention aims to provide a manually adjustable electro-mechanical mattress that allows the user to adjust and change the contour of the mattress and pillow to get the best support he or she wishes.

  • the control of zone height may be effectuated in real time, that is, while the user is on the mattress.
  • user adjustment of mattress zone height may be implemented via electronic storage of user-adjusted mattress contours and subsequent operation of mattress height actuators pursuant to the stored mattress contour.
  • mattress contour adjustment is effectuated while the user is lying on the mattress. Contour adjustments may be stored as “canned” contours per user direction.
