A surgical drape for use during surgery on a patient includes a sheet configured for covering at least a portion of the patient during the surgery. At least one pair of straps are configured on an underside of the sheet and extend in generally opposite directions laterally beyond sides of the sheet. The straps have a sufficient length so as to extend down below the support surface upon which the patient rests and engage with each other below the support surface, or with structure alongside the support surface, in order to restrain the patient in a desired position on the support surface.
