An emergency response treatment bed system. The emergency response beds may include a frame having a pair of opposing tubular stainless steel side supports and a pair of opposing tubular stainless steel end supports. The side supports and end supports are affixed each to the other by corner fixtures. A plurality of collapsible support legs are affixed to the frame. The support legs have an upper end and a lower end, and are adapted to support the frame above a selected substrate. A support deck is coupled to the frame. The support deck is adapted to support a patient body, and is provided with a liquid impervious, molded thermoplastic contaminant resistant cleanable surface. The support deck also has, above at least some of the support legs, a cutout portion defined by edgewalls, to provide access through the support deck to the support legs, so that multiple beds may be stacked one above the other, using support inserts between vertically adjacent support legs.
