Abstract: An invalid bed guard sheet is presented for use with invalid beds having raisable guardrails. The guard sheet has a standard flat horizontal sheet which is placed over the mattress. Continuously attached to the sheet are left and right guard pads which may be folded over the guardrails. The inner and outer pads are then fastened to each other by means of buttons, VELCRO (TM) strips, or other fasteners. The guard sheet eliminates the gap between the mattress and the metal guard rails, thus making the bed safer for patients. The cushioning effect of the guard pads also makes the patient bed safer and more comfortable.
