A folding trauma stretcher (10) having two rectangular frame assemblies (11 and 12) hingedly mounted together and supported by four legs pivotally mounted to the frame members, wherein the frame members are adapted to fold inward into a compact configuration for storage. The stretcher (10) includes a support structure for securing the stretcher in an open, unfolded position, the structure including brace arms (74 and 75) for preventing the legs from pivoting with respect to the frame assemblies and a stop plate (52) and locking means (87) for preventing the frame members from pivoting with respect to each other.
