wherein the handles and straps are secured between the top layer and the bottom layer.

2. The cover of claim 1 in combination with an air assisted patient transfer mattress.

3. The cover of claim 1 wherein the plurality of fenestrations comprises a screen and a webbing forming the bottom layer, wherein the screen and the webbing are configured to maintain the structural integrity of the bottom layer when a tugging force is applied.

4. A disposable cover for keeping an air assisted patient transfer mattress sanitary, comprising:

a sleeve having a top sheet, a bottom sheet, and a pocket formed between the top and bottom sheet;

a plurality of patterned fenestrations in the bottom sheet for passing air through onto a supporting surface from air release points in the patient transfer mattress;

wherein the plurality of patterned fenestrations occupy a central portion of the bottom sheet and align with the air release points in an underside of the patient transfer mattress;

a plurality of handles secured to the cover;

a plurality of straps secured to the cover; and

wherein the plurality of handles and straps are secured between the top sheet and the bottom sheet at one or more lateral edges of the sleeve.

5. The cover of claim 4 wherein the top sheet comprises a laminate having an absorbent layer and an impervious layer.

7. The cover of claim 4 wherein the top and bottom sheet comprise a non-woven material.

8. The cover of claim 4 wherein the sleeve includes a closeable opening.

9. A reusable cover for keeping an air assisted patient transfer mattress sanitary, comprising:

a first layer terminating in lateral edges, at least three of the lateral edges connected to a second layer to form a sleeve for housing an air assisted patient transfer mattress;

air passing means in one of the layers for directing air from the patient transfer mattress out of the sleeve onto a supporting surface;

wherein the air passing means comprises a pattern of fenestrations in a portion of the first or second layer;

further wherein the pattern of fenestrations is patterned to correspond with a location of air vents in the air assisted patient transfer mattress;

a plurality of straps secured to the cover between the first layer and the second layer; and

a plurality of handles secured to the cover between the first layer and the second layer.

10. The cover of claim 9 wherein the plurality of straps are releasably attachable over the first or second layer.

11. A method for keeping an air assisted patient transfer mattress sanitary, comprising:

providing a cover having a top layer, a bottom layer and an open end, the bottom layer having air passing means comprising a plurality of fenestrations the top layer and bottom layer being secured together at a lateral edge, a plurality of straps secured to the cover between the top layer and the bottom layer and a plurality of handles secured to the cover between the top layer and the bottom layer;

inserting the air assisted patient transfer mattress into the cover through the open end; and

aligning the plurality of fenestrations in the bottom layer with air vents in the underside of the air assisted patient transfer mattress;

wherein the plurality of fenestrations are patterned to occupy a majority of space comprising the air vents in an underside of the air assisted patient transfer mattress.

12. The method of claim 11 wherein the cover is moved with the air assisted patient transfer mattress.
