In a casket, a rigid bed frame is adjustably mounted at its end so that the casket bed frame can be raised, lowered and tilted. Mounted on the rigid bed frame is an adjustable body support positioned at about the thoracic area for raising the chest and lifting the chin off the chest. It is contemplated that the adjustable device has a pair of hinged frames with a power transmission mechanism for sliding one edge of the frame to pivot the hinged edges of the frame of the bed. Alternatively, an inflatable bladder underlies the body and is used to raise it, or is positioned between a pair of hinged members and causes the upper hinged member to raise the body. Two pairs of hinged members may be positioned across the width of the bed frame underlying the body, and the upper hinged member of each pair may be raised to different heights thereby allowing the thoracic area of the body to be rotated about a longitudinal axis of the bed frame.
