  • mattresses designed to provide orthopedic support to the resting user are made of layers of materials which do not allow the resting user to sink into the mattress and are thus uncomfortable.
  • Both of the abovementioned mattresses do not meet the modern health-care requirements of providing both comfort and orthopedic support, as one provides comfort without giving proper support to the resting user thereby inducing pain, the other provides a good support thereby sparing the user of induced pain, at the cost of comfort to the resting user. There is, therefore, felt a need for a mattress which provides both comfort and support to the resting user.
  • Some of the objects of the present disclosure which at least one embodiment herein satisfies, are as follows: It is an object of the present disclosure to provide a mattress that affords comfort to a user resting thereupon.
  • Another object of the present disclosure is to provide a mattress that affords orthopedic support to the user resting thereupon so as to reduce pain or any harm to the body-parts of the user.
