ABSTRACT:
The present invention is directed to a therapeutic bed comprising a mattress. The mattress has a fluid cushion and a fluid pump. The fluid cushion has a fluid support surface, a retractable/deployable bolster, and a closure mechanism. The fluid support surface has a top surface designed to receive a patient thereon. The closure mechanism corresponds to the retractable/deployable bolster and allows the retractable/deployable bolster to be deployed or retracted. When the retractable/deployable bolster is deployed the retractable/deployable bolster protrudes from the top surface and is positioned about a portion of the patient's perimeter. When the retractable/deployable bolster is retracted the closure mechanism is positioned over the retractable/deployable bolster to prevent the retractable/deployable bolster from protruding from the top surface. And the fluid pump provides a fluid to the fluid cushion.
