ABSTRACT:
A novel bed having a horizontal support frame affixed to a plurality of vertical legs and providing a stretchable mat made of a porous support surface which may be subjected to selected tension by a plurality of springs and spring adjustment bars whereby to selectively adjust the sag resistance of the support surface to the user's various body portions. The stretchable mat of the present invention is readily removed for washing and reinstalled by simply releasing the tension on the springs. The stretchable mat is of a porous nature which allows the body surfaces in contact with the mat to "breathe" and which also allows liquids to pass through the mat whereby to provide a means for avoiding unnecessary discomfort to an incontinent user or patient. One of the principal advantages of the present invention is the hygienic effect of avoiding the use of a dust producing mattress of conventional configuration which typically uses materials which deteriorate with time and are readily released through the mattress cover to create a dust problem adjacent the bed of the prior art. The bed of the present invention will, unlike the bed of conventional mattress and box spring configuration of the prior art, not sag with time. Any sag produced in the present bed as a result of protracted use can be readily removed by simply readjusting the tension of the springs whereby to always provide a non-sag surface to promote the healthful sleep and rest of the user. An optional lumbar support is also disclosed.
