Claim:
A drape for a tiered surgical operating table, comprising: a pair of elongated sheets connected at aligned distal ends to define a skirt for a drape, a first one of the elongated sheets defining a first side wall and a back wall and a second one of the elongated sheets defining a second side wall opposing the first side wall and a front wall opposing the back wall, each elongated sheet having a length exceeding a width and each elongated sheet having a first portion of a first width and a second portion of a second width greater from the first width so that side walls thereby define a stepped structure; a pair of paper and non-permeable material laminated tier sheets, a first one of the tier sheets attached on opposing sides to respective first edges of the first portion of the elongated sheets and a second one of the tier sheets attached on opposing sides to respective edges of the second portion of the elongated sheets; a central panel attached on opposing lateral sides to a respective transition edge of the elongated sheets between the first portion and the second portion thereof and attached on opposing second sides to a respective inner edge of the first tier sheet and the second tier sheet, whereby the central panel is substantially normal to the first tier sheet so that the drape has a stair-step structure; and the first and second side walls extending uninterrupted from the respective first edges to a free distal edge in a common plane remote from the first tier sheet.
