GEL-FILLED, VARIABLY-ADJUSTABLE CUSHIONING SYSTEM FOR SUPPORTING A PERSON Abstract of the Disclosure A cushioning device, which can be a mattress, mattress pad or seat for supporting a person by distri- buting force over a support area of the person's body, comprises a gel-filled flexible enclosure assembly with variably-adjustable supportive force distribution to prevent pressure points and resultant decubitus ulcers (bed sores) in patients and others who must spend long periods of time in prone or seated positions. The flexible enclosure assembly has multiple gel-containing compartments each underlying a different portion of the supportive surface of the device and preventing the transfer of gel from one compartment to another. Selectively openable and closable ports each com- municate between the interior of a respective compart- ment and the exterior of the enclosure for enabling the infusion or extraction of gel from a particular com- partment so as to variably adjust the distribution of supportive force. One or more gel containers, separate from the flexible enclosure, matingly couple with the respective ports for delivering gel to or receiving gel from the respective compartments. Gel is initially formed within each compartment by adding water to a highly absorbent gel-forming material provided in dry form with the compartment.
