A pressure reduction mattress construction for a liquid or gel bed having a flexible basin forming a cavity with inclines head and foot for surrounding and supporting a liquid or gel filled flotation bladder that is anchored to the head of the basin. The inclines made of a soft yielding material allow the head or foot of the bed to be easily raised as the liquid or gel moves toward the center of the bed. The head incline also serves to provide a soft yielding surface to support a patient after liquid or gel has naturally moved to the sacral area. The entire structure is then covered with a flexible and yielding hospital fabric cover, giving the bed the appearance of a conventional hospital mattress. An optional heater pad may be used with a fiber filled sacral/pelvic bladder placed over the heater pad. Buoyant fiber material may be secured to portions of the inner surface of the upper sheet that forms the flotation bladder to provide additional lift to portions of a patient's body and thus reduce pressure on other, more vulnerable portions of the body.
