Abstract

A disposable or reusable "crawl resistant" flexible mattress formed of panels sealed together to define alternately inflatable passages between the panels for sequentially supporting structure for a long term bed patient to reduce decubitus ulcers, bed sores, etc. The mattress has vent holes in its top for ventilating the patient with inflation gas and a crawl resistant layer bonded to a bottom of the mattress to prevent the mattress from "crawling" relative to the bed and patient during use. In one form of the mattress, crawling is reduced by a separation between the inflation passages so individual sections of the mattress can more readily conform to a patient's body contour.
